ABSTRACT: The paper discusses rectifier circuits shown in Fig. I of the Enclosure
for use in rectifier-type meters and employing germanium diodes. The advantages Of
using such dioded for this application are enumerated. Such diodes are going into produe-i
tion in the Zaklad "Tewa!l ("Tewall Plant). The circuits and the factors determining the i
temperature -error of rectifier-type meters are discussed,, and a formula for the tempera-~'
ture error due to the variation of the diode forward resistance with temperature is de-
rived. A simple method of compensating the temperature error due to the variation Of
diode characteristics with temperature Is shown. The temperature error due to the varia-1
pre
tion of the diode feedback resistance with temperature is also considered. The paper
sents some results of measuring the following parameters of some Polish germanium
point-contact diodes: static voltage-current characteristic, dynamic forward-current re

sistance vs current variation of the dynamic forward-current resistance for a tempora-
ture change of 100, variation of voltage-current characteristic with temperature from
-20*C to +40*C. On the baBis,of the experimental ~tnd theoretical results circuits were
developed for rectifier-type meters for current, range from 150,dA to 600 mA and volt
s ag
ranges from 1. 5 v to 600 v. Schematics of the meters are shown. The meters were
fabricated and 36 meters were tested for temperature error; the measurement results
are shown in a table. Their temperature error was small enough and all meters have
passed the Polish standard requirements. For volt metern the mmdmum frequency error
did not exceed 1. 5% and for millivolt meters and microampere meters it did not exceed
2. 0%. Orig. art. has: 9 figures, 5 tables and 18 formulaB.

TITLE: Infrared Radiation Absorbing Glass
PERIODICAL: Szk1o I Ceramika, 196o, No. 12, PP. 361 - 364
TEXT. As a result of the increasing demand (about 100,000 m2 annually) for
automobile windshields made of,glass which absorbs infrared radiation, the Centralm
Laboratorium Przemyslu Szklarskiego (Central Laboratory,of the Glass Industry) be-
gan laboratory and industrial tests connected with production t.echnology of 6-mm
thick glass absorbing about 70% of infrared radiation in the range of from 0.7 to
3:0/.k. The research was divided into a) laboratory tests, b) melting on small in-
dustrial scale in the Huta Szkla "Jaslo" (Glass Plant "Jaslo") and c) melting on
industrial scale in the ZSL "Walbrzych". Laboratory investigations were made on
glass melted in a laboratory furnace, and Its absorption properties were testedwith
a Zeiss spectrophotometer in the range of from 0.7 to 3-0/W. A normal d-c "Nitra"
lamp was used as infrared radiation source and the monochronomator was equipped
with saline prism making possible the measurement of infrared radiation up to 17/A
The test results revealed that the glass produced by the ZSL "Walbrzych" plant has

TOPIC TAGS: photosensitivity, photoconductivity, Impurity center
ABSTRACT* Results are given of an investigation of the spectral distribution of
Rhotocanductivity of InP n-type specimens with carrier concentrations from 1016 to
,-.,1015 cm-3 at 80 and 296K. Deeply located photoactive impurity centers with energies
of 0.33 and 0.14 ev and an impurity level with an energy of 0.04 ev were found in the
forbidden zone. The spectral distribution of natural photoconductivity measured at
80K Fhowed the width of the forbidden zone determined from X1/2 to be E G = 1.41 ev.
The peak of photosensitivity corresponded to X = 0.90-0.91 u. The natural photore-
sponse had a smaller value than the impurity photosensitivity, No correlation was
found between the electron concentration and the location of the peak within the in-
terval n - 1016_1018 cm-3. Measurements performed at 296K showed that Al 2 for the
peak of impurity photoconductivity corresponds to 1.21 ev. The width of t~e forbidden

zone at room temperature was EG - 1.35 ev. The presence of minority carrier traps
and the strong effect of the capture of nonequilibrium current carriers with the aid
of traps on the lifetime of electrons and holes were evident. The lifetime evaluated
by means of photoconductivity was of the order of 10-6 sec and the rate of surface
recombination was 104-2 x 103 cm-sec-1 and depends on the surface treatment. Orig.

TEXT:: Changes in plasticity properties of St 50 steel were
investigated at the Dnepropety-ovskiy Metallurgical Institute by
determining the relative elongation and reduction in cross-section
area of -wacuum-annealed specimens held for 1; 5, M 15 and 30 min
at temperatures in the range of 300 to 600'C, After annealing,
the specimens were examined by X-.rays (interference lines from
(110) and (220) planes), Tests were also made on cold-worked
specimens at 61.6 and 87.5% defoxination, Relative elongation
was found to increase with increasing temperature of annealing,
with a maximum of 6 to 7% corresponding to annealing tempsratures
within the range of 300 to 350'C, A further in--reasa of the
annealing temperature (up to 550'C) and spee~,imen holding for

dislocations and also by a non-uniform distribution of the
dislocations in the sub-grains volume (polygonization). The
increase in plasticity of the steel observed at temperatures
exceeding 5000C is ascribed to the onset of recrystallization,

The authors carried out experim.ents for the purpose
of producing tubes,with high mechanical properties and a surface
free from peeling-off scale.by ineans of induction heating (67 kc/5),
applying a special cooling regime. The tubes, made of the steel
(10sp) were )10 mm in diameter, 360 mm long, the wall thickness
was 1.5 mm and the heating speed was 600OC/sec. The heat
treatment consisted of heating to 10000C, quenching with water,by
ineans of a special tangential sprayer with slot openings,down to
700-6000C and then in air. This heat trea.tment ensured decomposi-
tion of the austenite in the range of pearlitic transformation.
As a result of these experiments, tubes with a clean surface and
high mechanical and technological properties were obtained. The
microstructure of the weld and of the near-weld zone did not

TEXTs Good understanding of the electron paramagnetic resonance of
the Fe3+ ion in corundum is of great importance in designing para-
magnetic amplifiers since, because of small distances between the
spin doublet, a small or even no magnetic field, permits the reali-
zation of paramagnetic amplifier in the centimetric frequency rang
as stated in T,,S. and A.M, -P-rnknorov (Ref. 1: ZhETTp
1959, 36, 91jj aaid J E. King, ana d.#. Terhune (Ref. 2s J. App-
Phys. 1959, 30, 1844~. For an arbitrary orientation of axes of the
magnetic field and of the trigonal axis, the Fe3+ ions form two
magnetic non-equivalent systems according to L.S. Korniyenko and

ing its own system of lines of various intensities. The richness of
this spectrum permits a good s-tdy of cross-relaxation phenomena in
a paramagnetic amplifier. The original work ol analysis of the pa-
ramagnetic resonance of the Fe3+ ion in A12 03 was carried out by
L.S. Korniyenko and A.M. Prokhorov (Ref. 3: Op.cit.), who showed
that the observed spectrum of the electron par-amagnetic resonance
can be explained by the spin-Hamiltonian as proposed by B Bleaney
and R.S. Trenam (Ref. '6; Proc. Roy. Soc., A., 1954, 223, ;); they
also measured its constants at room temperatures. The evaluation of
Eigen-values and of wave functions for parallel orientation was
done by V.M. Vinakurov, M.M. Zaripov and N.R. Yafayev (Ref. 7: ZhE
TT, 1959, 37, 312). In the present article the authorSevaluate the
numerical values of the levels of energy for an arbitrary orienta-
tion of the magnetic field with respect to-the trigonal axis in the
planes, for which all ions are magnetically equivalent. Numerical
results are compiled as tables and graphs which permit determina-

ABSTRACT: The author presents a selection of formulas and curves
needed for determining the dimensions of closed slots in the rotor of
induction motor. The formulas and curves are selected from four Soviet
and German sources mentioned as references at the end of the article.
The optimal dimensions are chosen from a series of various versions
calculated by using experimental curves and empirical data. The method
of calculation is based on calculating the magnetic permeance of closed
slot for various steels and slot sizes. An example of calculation is
presented for a 75 kw, 380 v, 740 rpm induction motor of A101-8 type.

The versions for semi-closed and closed slots are presented and the
results of calculations are compared. Then, the optimal size is select
ed as shown in a cross-section of the slot. The proposed method of
calculation can be applied to the design of Induction motors in accord-
ance with the GOST specifications. Orig. art. has: 5 figures,

TOPIC TAGS: computer, digital computer'. computer component
ABSTRACT: An experimental'recorder uniO-
Intended for receiving alphanumerical
information from digital computer is described; the infornation can be recorded on
a photo film or a xerox paper. A step register logically converts information and
makes up the lines on the film which enhances the speed of operation. A principal
circuit of the*recorder unit is briefly explained. IFK-120 flash lamps operating
with a very low duty factor help in transmitting characters to the photo film-
writing' density, 2000 lines pcr m. The writing rate of the new experimental ~idt is
clai&ea to exceed that of the regular "Ural-2" computer by 11 times; it can be
varied within 1-13200 lines per min. Orig. art. has: 2 figures and 5 formulas.

Generally practical experience helps the students. The author
states that systematio excursions to industrial works are an
important educational factor. New methods of instruction
resulted from ,he possibility of teaching directly at the
plants. The Komsomol organizations also tell the students to

ABSTRACT: The origin of the arc in butt condenser welding is analyzed.
On the basis of existing data it is concluded that the major
factor of the arc origin is the melting of micrcprotrusiors
on the c.,nds of the parts to be welded, and vapor formation
of the metal. If there are such vapors in the interelec-
trode gap, the development of the discharge can be explained
on the basis of the thermo-electronic theory of the arc.
Stability of the arc depends mainly on the transitional
contact resistance. A formula is recommended to calculate
the melting coeeficient which determines the quantity of

ABSTRACT: During the post-war years, the number of higher educational
institutions in the eastern districts of the USSR has rapid-
ly increased. There are in Sverdlovsk alone 11 higher schools
(including the Ural Polytechnical Institute with 20,000 stu-
dents). Professor 'A.G. Chilikin fRef 2_7 was right in
asserting that the demands raised by industry in respect
to higher school graduates have considerably changed. Soviet
industry now requires a specialist of versatile education
With a thorough theoretical and good practical training.
The vuzes, however, while supplying the students with
gufficient theoretical knowledge, do not ensure the required
practical training, thus compelling the young engineer to
complete his education at places of production. The admit-
tanas of studenta with a record of practical experience
radically changes the situation. In 1957, the Ural Poly-

Ural Polytechnical Institute with 10 day-time faculties and
over 9,500 students, 3 evening faculties with 1,700 students
and 3 correspondence faculties with over 8,700 persons, is
one of the most flexible types of educational institutes,
ensuring a connection between theoretical education and
practical experience. This combined type of a polytechnical
vuz is considered by many other vuzes as the most rational
one, where students of the junior courses study by correspon-

TITLE. The Influence of Additional Capacitance on Current
Cotimiutation
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy, Elektromekhanika,
1959, Nr 6, pp 34 - 40 (USSR)
ABSTRACT: A very brief review is given of recent work on the physical
processes of the final stage of current commutation in
machines. The process is explained with reference to the
diagram in Figure 1. The short-circuit time T in the
diagram generally differs from the actual time of the
electro-magnetic transient commutation process, so that
there is a residual current L 0 at the instant when
contact is broken. Previous authors have noted the
influence of the coil capacitance on the commutation current,
its effect being to reduce the probability of sparking.
Since the natural capacitance of a coil is very small, Tur,
in an article in Elektrichestvo, 1956, Nr 11, described
the effects of including an additional capacitance ten
Cardi/6 times as great as the natural capacitance.

sov/144-59-6-5/15
TLie Influence of Additional Capacitance on Current Commutation
In order to study the influence of such additional
capacitance, the authors built a rig, the schematic
circuit diagram of which is given in Figure 2. The
parallel circuits of the machine are represented by
tw-j generators and the portion undergoing commutation
by an inductance and resistance in series shunted by
a capacitance. A cominutator is provided and as it rotates
the section investigated is periodically shorted. The
inductance and resistance were given values typical of
ail ordinary machine but the added capacitance was
lo-14 -~LF. This i4 much greater than typical normal
values of 9 x 10 IiF but was necessary in order to
reveal the influence of capacitance on commutation.
The equipment was used to plot curves of sparking threshold
and of permissible sparking zones both with and without
capacitance. The curves shown in Figure 3 represent the
threshold of sparking taken with the natural capacitance
of 2 x 10-4 IiF and with an additional capacitan ce of 10 IiF.
Card2/6 It will be seen that the addition of capacitance displaces

SOV/144-59-6-5/15
The Infiuence of Additional Capacitance on Current Commutation
the curve of sparking threshold in such a way that the
cotmnutating properties are Improved and, in addition, the
zone of permissible sparking is extended. Equations (1)
and (2) are the main differential equations of the final
stage of conLnutation; they are solvgd in an appendix,
where it is shown that when C =L/r the commutation
process is aperiodic. If the ohmic resistance of the
section is constant the capacitance at which the aperiodic
process cotimiences depends on the section inductance, as
indicated in Table 1. It is shown that the values of
current in the capacitance, current in the section, voltage
in the section and rate of voltage-restoratlon are primarily
functions of the current in the capacitance at the instant
,;-rhen the brush breaks circuit, which is taken as the initial
time.
If the process is periodic the current and voltage in the
section each consist of two components: one is constant

T.he Influe-ice of Additional Capacitance on Current Commutation
By increasing the capacitance the frequency of the
,eriodic component is decrased.
In actual machines the natural capacitance of the commutator
and section is always much smaller than the values given
in Table 1, uhilst the values of inductance and resistance
are similar; thus, a damp*d periodic process is always
present in actual machines.
An oscillograni of the section voltage taken on the 4
experimental rig with the natural capacitance of 10 jiF
is given in Figure 4. It will be seen that in this case
t1te variable component of the voltage becomes a peak. An
oscillogram of the current in the section in the presence
of additional capacitance is given in Figure 5 and if the
current curve is compared with one constructed from Eq (13)
of the appendix it will be seen that the agreement is good.
Correspondingly, the oscillo~Zram of Figure 6 and Eq (14)
of the appendix relate to section voltage and are in good
agreement.
Certain differences between conditions in actual machine

reference to the sketch in Figure 7. It is shown that
there is a certain voltage U I at which the contacts
can break without arcizig, even though there is a consid-
erable current before the circuit is interrupted.
Comniutation can be improved by reducing the voltage;
in general, this is only possible by reducing the constant
component by the use of interpoles or by reducing the
amplitude of the varying component by increasing the
capacitance. In the limiting case, when the capacitance
is sufficient to make the process aperiodic, the amplitude
of the section over-voltage is equal to the constant
component and if this is made equal to the voltage U 1
no sparking will occur, whatever the value of current
int errupt ed.

ABSTRACT: The Uralelektroapparat works operates in close
collaboration with the Ural Polytechnical Institute
imeni S.M. Kirov. Many students of the MuLtit%te are at
the works, and many of the works' staff lecture at the
ImUtate. The Zutitmte is doing research for the works,
especially on the reduction in size of oil circuit-
breakers. D=ents. I.I. Ponomarevq R.L. Malkin&. and
A.A. Oatul have developed a method of designing
and ellipsoidal cylindrical tanks and have shown that the
rating of oil circuit-breakers can be increased without
using thicker tank walls by making use of the plastic
properties of the materials. I.V. Tarlinskiy and
A.N. Kosukhinj have also done theoretical and experimental
work on this problem. It has been demonstrated that
breaker ratings can be increased without increasing size.
At present, R.L. Malkina, V.V. Kolobov, L.L. Ghemerinakiy
Card .1/3 and A.N. Kosukhin are working on the calculation of
dynamic loading of circuit-breaker tanks and their

foundations which is a neglected problem of practical
Interest. Engineers from the works, including
V.k. Yiditskiyg G.L. Chetchuyev, T.Ya. Buben, B.I. Rader,
are also participating in practical and theoretical
research work. There is already a need for circuit-
breakers with a rupturing capacity of 25.million kVA at
500 W. Because the requisite short-circuit testing
facilities are very expensive, Dnter 49 tWWw1esLSi1AmWW NJ,
Akod:Ls is investigating artificial testing circuits. The works
is at present completing the construction of a short-
circuit testing station using these methods9 which will
give ratings of 5 to 10 million VA. By further
development it is expected to obtain equivalent ratings
of 30 to 40 million kVA from a short-circuit testing
laboratory with a normal rating of 5 million VA.
Assistance has also been given to the works in the design
of are-suppression devices for oil circuit-breakers.
A recurrent-surge cathode ray oscillograph with electro-
magnetip shutter has been devised for the study of
Card 2/3 transient processes in rectifiers and high-voltage
circuit-breakers. A good deal of work has been done

A P.1ant and a VTUZ SOV/110-59-7-9/19
on the cooling of electrical machines under the guidance

cal Sciences*, P.S. Mamykin, who works on the technology of
silicates, has helped the works in the manufacture of
ceramics. The works has collaborated in drafting the

TITLE: The Influence of the Method of Connecting the Stator and
Rotor Windings on the Operation of a Doubly-fed Motor
PERIODICAL; Izvestiya vysshikh uchebnykh zavedenly,
Elektromekhanika, 1959, Nr 9, pp 15-19 (USSR)
ABSTRACT: Despite their advantages, doubly-fed motors are not yet
widely used, mainly because they will not run up to speed
independently. They have also a tendency to hunt, but
this can easily be overcome. Schematic circuit diagrams
of such motors, both with series or parallel connection of
Stator and rotor windings, are given in Fig 1 and circle
diagrams are constructed in order to study their
behaviour. To this end, expression (6) is derived and
curves of mutual reactance as functions of magnetising
-urrent are given in Fig 2. With the windings connected in
series the properties of the circle diagram depend upon
whether the transformation ratio from primary to secondary
is unity or not. If it is unity the applied voltage is
Card 115 divided equally between stator and rotor and the magnetic
flux remains practically constant over the working range
V

Windings on the Operation of a Doubly-fed Motor
though the saturation diminishes somewhat near maximum
loads because of the voltage drop in the windings. The
iron becomes saturated near the no-load point at which
the circle diagram of current is distorted and passes from
circle 1 to circle 2 of Fig 3. If the transformation ratio
is not unity the magnetic flux is not constant because the
magnetising current is not constant, and when the motor is
running at full speed and load the stator voltage is greater
than the supply voltage. Experimental curves of the
increase in voltage on the windings as the load is increased
with a transformation ratio of 0.345 are given in Fig 4.
A circle diagram for the case when the transformation ratio
is 0.345 is given in Fig 5. As the magnetising current
rises and the mutual reactance drops, the current curve
passes from circle 1 to circle 3. The maximum torque and
the overload capacity are much lower than when the
transformation ratio is unity. The case of parallel-
connected windings is then considered. Eq (9) is derived
Card 215 and it is found that when the transformation ratio is unity
the current diagram is the same as for the series case*

The Influence of the Method of Gonnecting the Stator and Rotor
Windings on the Operation of a,Doubly-fed Motor
When the transformation ratio is not unity the voltages
applied to stator and rotor must be such that the volts
per turn on both is the same, otherwise energy passes
between stator and rotor by a transformer effect, which
increases the losses and impairs the power factor. A
circle diagram for the case when there is a different
number of turns on the stator and rotor is given in Fig 6.
Here the transformation ratio is 0.345, and although the
performance is not so good as when the transformation ratio
is unity, its deterioration is not so great as in the case
of series connection. For purposes of comparison, data
for doubly-fed motors with series and parallel connection
and various transformation ratios are given in Table 1.
The data apply to a motor type AK-52-4 which, under
induction-motur conditions, has a rated output of 4.5 kW
and a power factor of 0.83. In an induction motor7 power
is supplied only to the stator and the rotor carries only
Card 3/5 the power loss, whilst in the doubly-fed motor power is
applied both to the stator and to the rotor. Since the
rotor is fully utilised in the latter case, the power t,//

output is double that of an induction motor with the same
rated current. The magnetising current of the doubly-fed
motor is also less because the resultant magnetic field
is created by the turns of both stator and rotor and so
the poVor factor is greater, being about 0.98. Iron
losses In the doubly-fed motor are double what they would
be in an induction motor but since the other losses
remain the same and the output is doubled) the efficiency
is greater. To confirm the above statements, tests were
made on motors for speeds of 2000, 3000 and 6000 rpm with
various transformation ratios. Curves of current,
active and reactive power, efficiency and power factor as
functions of useful output on the motor shaft are given
in Fig 7, for machines of the same size as a wound-rotor
induction motor of '+.5 kW. The tests confirm that the
motor has a good performance and that the power output is
doubled at the rated current of 30 IL. Points obtained
from the circle diagram are given in Fig 7 and show good
Card 4/5 agreement with the test results. It is concluded that

ABSTR.'---, In recent years considerable attention has been paid to
the development of single-machine frequency-changers in
order to reduce the weight and dimensions of the
equipment. However, the complexity of the electro-
magnetic processes in these machines and the inadequate-
understanding of their properties have hindered their
widespread introduction. The present article gives some
results of an investigation of a machine of this kind
converting from 50 to 200 c/s, the machine being in effect
an induction motor and a synchronous alternator with a
common magnetic system. The stator slots of the machine
contain two three-phase windings without mutual
Card inductance. The first (1), corresponding to the motor,
1/8 has an appropriate number of poles, and the other (4)
corresponding to the alternator, has a different number

of poles. The rotor carries a squirrel-cage winding (2)
and an alternator field winding (3) with an appropriate
number of poles. The alternator field winding is
energised through slip-rings from a rectifier (5)
supplied from a voltage-stabilising device. The winding
(1) is connected to a 50 c/s supply and by reaction with
the rotor winding (2) drives the rotor. The complete
circuit arrangement is shown in Fig 1. When the
alternator is loaded, interaction between its windings
(3) and (4) sets up a retarding or generator torque which
reacts directly on the driving or motor torque, so that
no surplus torque appears at the machine shaft. The
process of power conversion is illustrated by the energy
liagram of Fig 2. The influence of the one machine on
the parameters and characteristics of the other when both
have a common magnetic circuit is described by reference

tested with identical results. The most important data
of the frequency-changer type OPCh-3 are given in
Table 1. Calculated values of motor and alternator
induction and of total induction are given in Table 2.
Load tests showed that the temperature rise of the
windings was within the limits permitted by the standard
GOST 183-55. The temperature rise by resistance was
51 OC for the stator winding and 39 OC for the field
winding. The external characteristics of the alternator
with the voltage stabiliser in operation at unity and
0.75 power factors are plotted in Fig 3. Oscillogram
charts of transient processes in the frequency-changer are
seen in Fig 4. Here, chart 1 corresponds to starting
U'-he motor at full supply voltage with the stabilising
ievice connected to the alternator. Chart 2 corresponds
to a sudden three-phase short-circuit of the stabilised
'ilternator. Corresponding oscillograms with the voltage

rated load with the voltage stabiliser in use. It will
be seen that the transient processes in a high-frequency
alternator built in a common magnetic circuit with a
motor, do not differ from those for normal alternators
excited by semiconductor rectifiers. Analysis of
oscillograms of steady-state and transient conditions
with various degrees of saturation of the magnetic
circuit indicate that under all conditions the combined
machine behaves like the alternator and motor in a two-
machine set. The motor currents and e.m.f.'s do not
contain harmonics of the alternator frequency and its
e.m.f. curve does not contain harmonics of the power
frequency. Both current and voltage wave-shapes are
satisfactory. Fig 5 gives oscillograms of phase-
voltages and currents of the motor and alternator parts
of the frequency changer on no-load and at rated load.
The tooth harmonics occurring in the phase-voltage of
the alternator can easily be prevented by a more
suitable choice of winding pitch or by skewing the slots.

with different pole pitches gives rise to a number of
effects associated with changes in permeability when the
steel is magnetised simultaneously by fluxes of the
different frequencies. This point is briefly discussed,
and a formula is given for the change in reluctance of
the magnetic circuit of one part of the machine due to
the presence of the field of the other. The increases
in reluctance of the magnetic circuit with increase in
alternator flux and motor flux are plotted in Figs 6 and
7 respectively, both for different levels of saturation.
Analysis of these figures and of the data given in Table 2
shows that the increase does not exceed 1.25 provided
that the sum of the generator and motor induction in each
section of the magnetic circuit does not exceed the normal
values of induction for ordinary machines. The leakage
reactance of the one part of the machine is little
affected by the presence of the field of the other. The
iron losses in the combined machine may be greater than
the sum of the losses with separate magnetisation2 as is
illustrated by the graph plotted in Fig 8 for various

values of generator and motor field. This graph and the
data given in Table 2, and test results from other
examples of frequency-changer, indicate that the iron-
loss increase does not exceed 1.25 provided that the
total induction of the alternator and motor in other
parts of the magnetic circuit does not exceed normal
values of induction for ordinary electrical machines.
Operating characteristics of an experimental frequency-
changer type OPCh-3 are plotted in Fig 9; the rated load
efficiency of the set is 71%, allowing for field losses.
The maximum efficiency of 72% is achieved at three- L/
quarters rated load. At rated load the power factor is
0.92. The efficiency and power factor remain quite high
down to half load. The performance of the experimental
frequency-changer may be assessed by comparing it with a
two-machine frequency-changer set using an induction motor
type KU-72, Kith a rigle-machine synchronous frequency-
changer type PSCh-5.~nll three have an induction motor

(50 c/s) and voltage (220/380 V). The principal data
of the machines are given in Table 3. It will be seen
that the experimental machine has the highest efficiency
and power factor and smallest weight per unit output.
There was also economy in steel of 30% and in copper of
4.5% as compared with a machine type FSCh- 2, It should
be pointed out that the design of the exper mental
frequency-changers OPCh-3 was not ideal, being limited by
the slot geometry of the stampings of induction motor
type MR-53-4. The following students participated in
the design of these frequency-changerst A.V. Dvornikovj
Yu.K. Cherepanov2 B.G. Balter, S.I. Kazakova, and
Yu.K. Rad'ionov. The calr-Ulntions demonstrated that the
performance of the new machine as compared with a two-
:aachine set improves with increase in output. The
economy of material becomes 30 - 60%. The efficiency of
the new machine is equal to or somewhat higher than that
of a two-machine set, and the power factor is higher.
The motor and alternator reactances of the new machine are
7/8 of normal value and it is appreciably smaller than a

On the basis of the investigations carried out the new

use. The machine, partially dismantled7 is depicted in

TEXT~, Current commutation by a mechanical rectifier in the
field circuit of a synchronous motor may be improved by
shunting the rectifier brushes by ohmic resistance. However
such resistances lower the efficiency of the rectifier.
Better and more efficient commutation may be obtained by using
additional capacitances instead of the shunt resistances. In
view of the previous article by some of the present authors~
published in this journal, 1959, No. 6, the operation of
mechanical rectifiers is now considered and the conditions
necessary to obtain sparkless commutation are established.

Fig. L shows a circuit of a single--phase mechanical two--plate
re:tifier with supply transformer. The differential equation
for the concluding stage of commutation is given and analysis
of its solution makes it possible to establish a physical
picture of the processes during current zommutation, Near the
point where the voltage of the supply to the rectifier passes
through zero there is a certain current when the transformer
and load circuit are interrupted. As both transformer and
load have appreciable inductance, a charging current passes
into the capacitor, Later the capacitance disc~harges,
partially through the transformer winding and partially through
the load, The process of discharge may be periodic or aperiodic.
Since the natural ^-apacitance of the transformer is small,
c.onsiderable over-voltages are set up in the process of current
switching, their peak values reach 200 -- 230 V. These over-
voltages can cause severe sparking at the brushes, As the

ABSTRACT: An editorial note states that the method was developed

t e
Previous work has shown that commutation of motors may be
improved by connecting capacitors either between
individual commutator bars or between the main brush and
an auxiliary brush located behind its trailing edge. The
second of these methods is more convenient because it
does not involve mounting capacitors on the armature but
it is somewhat less effective. The tests described were
made on a d,c, motor of 6,8 kW4 220 Vj 1000 rpm, An

circuit on the section, the voltage across the section
is restored on a rapidly damped curve, in az~~ordance with
the theoretical conclusions of an article published by
the author in Elektromekhanika, 1959, Nr 6. These
overvoltage peaks can vary over a wide range. A graph
of the ovevvoltage amplitude as a function of the
capacitance connected for the motor under test is
plotted in Fig 3 and it will be seen that the curve is
asymptotic. The first ten microfarads of capacitance
notably reduce the overvoltage: thereafter considerable
increase in capacitance causes relatively small further
decrease. It was found that on introducing capacitance
into the auxiliary brush circuit, the zone of sparkless
operation is extended by 20 to 25% and is limited by
sparking at the auxiliary brush. A graph of the
amplitude of overvoltage as a function of interpole
boost is plotted in Fig 4 and shows that up to a point,
interpole boost reduces the overvoltage amplitude.
Beyond this point the overvoltage increases again,
