    摘要： Three-phase alternating current motor with Y-connected windings adapted to operate on single-phase source by disconnecting one leg of Y from other two legs, connecting the disconnected leg in series with a running capacitance across the single phase supply, connecting said two legs in series with a shuntable inductance across said supply. The coils of two voltage-sensitive relays for respectively shunting said shuntable inductance, and disconnecting a starting capacitance, each at different motor speeds, are connected in parallel with the aforesaid disconnected leg of the motor winding.
