ABSTRACT:
A 3-phase, alternating current electric motor or generator having a stator winding comprising three phase-windings in start-connection wound on a stator having a slot-number not divisible by "3", yet providing a substantially balanced 3-phase winding. The stator winding coils are disposed to provide a high positive-sequence distribution factor and a low negative-sequence distribution factor. This is achieved with two of the phase-windings having an equal number of coils to each other, the third phase-winding having a different number.
