The effect
of such change, however, would the same
as reducing the number poles one-half,
and thereby doubling the speed any given
25 motor.
2. the eight poles may either alter
nately opposite there may any given
time alternately two like and two opposite
20 poles. This readily attained making
the proper electrical connections. If
this not the case, there will certain
unevenness action which the less appre-
40 ciable the number poles greater; but
even this may measure corrected by
special provisions which not here neces
sary explain. These multipolar motorshave
rS peculiarity which maybe often utilized to
great advantage.
It obvious that the electrical transform
ers described prior patents and
jo which have independent primary currents
may used with the generators herein de

tend produce free pole the ring be
tween them and the twelve coils be
similarly wound. The combination, with alternating-
current generator having independent in
duced circuits and constructed adapted 80
produce given number current impulses
or alternations for each turn revolution, of
motors having corresponding energizing-cir
cuits and poles which number are less
than the number current impulses pro- 85
duced each circuit turn revolution
of the generator, set forth. these and other respects will be
seen that the invention involves many im
portant and valuable features. also follows, matter
of course, and from the above obvious,
43 that the number the poles the motor
be greater than that the generator the mo
tor will revolve slower speed than the
generator. The motor with twelve coils or
sixpoles, will rotate with twice the speed the
generator, and the motor with eight coils or
four poles, will revolve three times fast as
the generator. The combination, with alternating- 50
current generator comprising independent
armature-circuits formed conductors al
ternately disposed, that the currents de
veloped therein will differ phase, and field-
magnet poles excess the number arma- 55
ture-circuits, motor having independent
energizing-circuits connected the armature-
circuits the generator, substantially set
forth. The combination, with source alter- 60
nating currents which differ phase and com
prising rotating magneto-electric machine
yielding given number current impulses
or alternations for each turn revolution, of
a motor motors having independent ener- 63
gizing-circuits through which the said cur
rents are caused flow, and poles which in
number are less than the number current
impulses produced each motor-circuit by
one turn revolution the magneto-ma- 70
chine, set forth.
It may stated with respect the de
vices hereinafter set forth that the most per-
35 feet and harmonious action the generators
and motors obtained when the numbers of
the poles each are even and not odd. For example, the motor

What claim invention is—
1. single revolution the
disk cylinder the twelve polar projec-
S tions which are opposite polarity, will
therefore produce twelve current impulses in
each the circuits W'.
4. The combination, with multipolar al
ternating-current machine having independ
ent induced current-generating circuits, of
motors having independent energizing-cir- 75
cuits and smaller number poles than the
generator, set forth. Hence the motor
X, which has sixteen coils eight free poles,
will make one and half turns the gener-
io ator’s one.
