TITLE: The Reaction of Commutation Currents in Transverse-Field
Dynamoelectric Amplifiers
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy,
Elektromekhanika, 1958) Nr 12, pp 47-51 (USSR)
ABSTRACT; In d.c. machines under normal conditions of operation the
magnetic effects of commutation currents are only
significant under transient conditions. In transverse
field rotating amplifiers the commutation currents (c.c.)
have a delaying action and also oppose the flux from the
control winding. A number of methods have been proposed
for calculating reaction effects. That due to Epshteyn
is much used but it is laborious and introduces a 'brush
overlap coefficient' (Ref 3) which describes commutation
incorrectly. M.M. Tarashchanskiy (Ref 4) represents the
current in the commutated sector as the sum of recti-
linear and auxiliary components. Only the latter cause
reaction effects and the estimate is not accurate enough.
V.I. Radin (Ref 5) calculates the magnetizing force of
Card the c.c. on the assumption that the resistances of the
leading and trailing edges of the brush contact are equal
1/3 and constant, but the accuracy is no better than with VX

Epshteyn. The process of commutation is most truly
represented by the method due to M.S. Mikhaylov-
Mikulinskiy (Ref 8). The commutating circuit is
represented by an equivalent network and the auxiliary
currents are found by a superposition method. The
formulae for these currents in the EM`U-5P and EKU-12A
amplifiers are respectively Eqs (1) and (2), where ez
is the resultant e.m.f. of the commutating sector,
R is the transfer resistance when the-brush width and
collector pitch are equal. The magnetizing force of
the c.c. is Eq (3), where w is the number of turns in
the commutating sector. Tab e 1 compares the results of
the four methods of calculation with experimental values
obtained by M.I. Alyablyev's method (Ref 7). The
agreement is poor. It is therefore proposed to represent
the auxiliary current by a sinusoid, as in Fig 1. Since
the 'brush overlap coefficient', 0, usually lies between
1 and 2 commutation must occur partly in one sector and
Card. 2/3 partly in two. In the latter case the resulting current
can be found from the vector diagram of Fig 2, where the
V*_

shift angle is Eq (6). The demagnetizing force varies
between two limits and the average value is Eq (10), or
in terms of the branching coefficient K (Fig 3)q
Eq (12). Table 2 compares calculations by this formula
with experimental results (obtained as before) for three
different machines under two conditions of operation.
The agreement is very satisfactory. The magnitude of the
auxiliary current was calculated from a formula, Eq (11),
due to Arnold (Ref 10).

TITLE- On the Commutation of --- Si~a-.11 DC Machines
PERIODICALf Izvestiya vysshikh uchebnykh zavedeniy, Elektromekhanika,
1959. Nr 2, pp 73 -- 75 (USSR)
ABSTRACT, A study was made of commutation, with particular reference
to amplidynesj?ktaking the transient brush contact resistance
to be a function of current. Using the equivalent circuit
of Figure 1, expression (1) gives the differential equation
of the current in the commutating section, where r 1 and
r2 are the transient resistances of the leading and
trailing parts of the brush. In formulating the equation
it is assumed that the brush is the same width as the
commutator bars and that there is no commutating e.m.f.
In this equation the two transient resistances are taken
as functions of current density. An experimental curve of
transient brush contact resistance as a function of current
density for a brushgrade EG-8, used in amplidynes, is
Plotted in Figure 2; it is a straight line. The values

of r 1 and r 2 required in Eq (1) can be obtained from
this curve using Eqs (2). (3) and (4). The current
densities are given by Eq (5). Eqs (5) and (4) are then
substituted into expression (1) to give the non-linear
differential Eq (6). This equation is solved by the method
of successive intervals.
Curves calculated in this way are compared with oscillograms
for two different experimental cases in Figures 3a and b.
In both cases the good agreement between the experimental
and the theoretical curves shows that the transient
resistance of the brush contact considered as a function
of current density has an important influence on the
changes in current in the commutating section and so
should not be neglected.
There are 3 figures and 6 Soviet references.

TITLE: Tn-e-C-ommutation of Cross-field Amplidynes
PERIODICAL: Izvestiya vysshikh uchobnylch zavedeniy, Elektromekhanika,
1959, Nr 6, pp 66 - 70 (USSR)
ABSTRACT. A study was made of commutation in a cross-field amplidyne,
making allowance for the non-wlinear relationship between
the transient resistance of the brush contact and the
current density. It is shown that the work of Tur, published
in Elektrichestvo, 1956, Nr 11 and relating to a normal
DC machine is not applicable. Accordingly the equivalent
circuit of Figure I was used, which introduces lChe transient
resistance of the brush contact directly.
Eq (1) is the differential equation that describes the
change of current in tile commutating circuit. In formulating
this equation it is assumed that there is no commutating
e.m.f. and that the brush width is equal to the commutator-
bar pitch. An experimental curve of the transient
resistance of a brush contact as a function of current
density for brushes grade EG-8 used in a cross-field
Cardl/3 amplidyne is given in Figure 2. This curve may be

Tbe Commutation of Cross-fleld Amplidynes SOV/144-59-6-8/15
approximately represented by the exponential equation (2).
It should be noted that because of manufacturing variations
the transient resistance of this grade of brush as a
function of current may sometimes be exponential and some-
tinies linear.
Various subsidiary equations that are required are derived
and are substituted in Eq (1) to give Eq (5). The latter
was solved for a particular case by the method of successive
integration to give Curve 1 of Figure 3. Other curves,
corresponding to equations obtained by other authors, are
also plotted in Figure 3 to check their validity in
relation to a cross-fi-eld-amplidyne. It will be seen that
Curve I agrees best with test results. This is because
non-linearity of the transient resistance of the brush
contact has a considerable influence on the change of the
current in the commutating section. and should be allowed
for in analysis of commutation in cross-field amplidynes.
The differences between Curve 1 (theoretical) and Curve 5
(experimental) result partly from the approximate nature of
Card2/3 the solution of the differential Eq (5) and partly from

The Conmiutation of Cross-field Amplidynes SOV/144-59-6-8/15
disregard of armature reaction in the amplidyne.
The curves of other authors do not in general agree at
all well with the experimental values.

ABSTRACT: T~ie cross-field amplidyne has two sets of brushes, so
that the current distribution in the armazure vrinding
is not uniform and co;-inidutuation is poor,, There are
several stator windings, each of which affects
com-...iutation., It vas accordingly decided to make
tests of co~rimutation in cross-.field amplidynes, and
this article gives some information on the infiuence of
the compensating winding and intuerpoles on the process
of commutation, if the amplidyne direct-axis armature
reaction is not compensated, the a-raplidyne cannot work,
and under- or over-compensation are causes of unstable
operation. Sparking is often attributed to tlie brushes
or to out-of-balance when in fact it is due to incorrect
c.o,:'.i

ABSTRACT: A Zr-Nb phase diagram is plotted. The mechanical and certain
physical properties of alloys (A) thereof are investigated relative to
temperature and time. The A are made in an arc furnace with a W
electrode in an Ar atmosphere. The charge employed is Zr iodide
containing 1.50/o Hf also Nb foil with 10/o Ta added. After repeated
remelting, contamination with W is
