Abstract
A three-phase asynchronous motor squirrel-cage rotor structure capable of reducing starting current and a motor. The squirrel-cage rotor structure includes: a rotating shaft; a rotor core fixedly provided on the shaft; conducting bars provided in the rotor slots of the rotor core; two end rings fixedly provided at ends of the rotor core and integrally connecting the conducting bars to form a short circuit; and two starting rings provided at the outer ends of the end rings. The starting rings are fixedly connected with the end rings, with the gap therebetween being greater than 0 and less than 3 mm so that magnetic resistance between the end ring and the starting ring is reduced in the starting process of the motor, the eddy current effect of the starting ring is improved, the weakening effect on the starting current is improved, and the starting current is reduced.
