ABSTRACT:
A single phase induction motor of the capacitor start, capacitor run type, has a rotor and stator of conventional polyphase design and a two phase stator winding comprising a main winding with approximately 70% as many turns as a comparable conventional single phase induction motor and an auxiliary winding in series with the main winding, the auxiliary winding having two branches wound in opposite directions, each branch having substantially the same number of turns as the main winding. One branch of the auxiliary winding is connected in series with a running capacitor and this combination is in turn connected in parallel with the other branch. The series arrangement of the main and auxiliary winding is connected to the supply line and a starting capacitor may be paralleled with the running capacitor during starting for improved starting torque in the conventional capacitor start manner. In one embodiment of the invention the main winding is a single winding and in an alternate embodiment it has two branches each connected in series with the respective branch of the auxiliary winding.
