The invention relates in general to winding machines
and more particularly to a winding machine designed to
wind two differently shaped coils.
My prior Patent 2,791,121 issued May 7, 1957, shows 10 a form shown as the outer member or stator 15 of a ro
tary dynamoelectric machine.
a mechanical movement device which may be used for
winding a coil, for example, on a dynamoelectric machine
to wind the ?eld windings thereof on salient pole pieces.
The present machine may also be used to wind coils on
This may be an induc
tion motor, for example, of the shaded pole type and in
such case the coils 12 and 13 become ?eld windings on
salient pole pieces 16 of this stator. The stator 15 has
pole pieces of a dynamoelectric machine, for example, 15 been shown with two pairs of pole pieces although any
number may be used, and these pole pieces have pole
