    摘要： A high starting torque induction motor with simultaneously reduced starting current adapted to be associated with a drive having a high load torque on starting that includes a stator, a rotor, a first end ring fixed on said rotor, a second movable end ring associated with said rotor and having a lower electrical resistance than the first ring, and a centrifugal device associated with the second ring and operable upon the rotation of the rotor at a predetermined speed such that, when the motor is electrically energized, the high resistance of the first ring produces a high starting torque at reduced starting current, and when the motor achieves a predetermined speed, the second ring is moved into engagement with the first ring reducing the effective resistance and permitting normal operation of the electric motor.
