What claim invention is—
1. For example, the motor coils
25 may all alike, but those one energizing
circuit connected parallel while the others
are connected series, the connection in
each eaitgizing circuit may alike, but the
- currents directed through them may of

For example, one set energizing coils may
be finer wire than the other, have a
iS greater number convolutions, each cir
cuit may contain the same number convo
lutions, but composed different conductors,
as, for instance, one copper, the other of
German silver. The combination with source alter-
