Abstract

The invention provides a squirrel-cage rotor assembly, a squirrel-cage rotor and a motor. The squirrel-cage type rotor assembly comprises a rotor iron core which comprises tooth grooves; the conducting bars are arranged in the tooth grooves in a penetrating manner along the axial direction of the rotor iron core; and the supporting piece is filled between the conducting bar and the tooth groove wall. The filling type supporting pieces are arranged between the conducting bars and the tooth grooves of the rotor iron core, the supporting pieces play a supporting role and have corresponding structural strength, and shape distortion of the conducting bars can be prevented when the conducting bars are machined in the rotor iron core.

Description

technical field [0001] The application belongs to the technical field of motors, and in particular relates to a squirrel-cage rotor assembly, a squirrel-cage rotor and a motor. Background technique [0002] At present, my country's industrial energy consumption accounts for about 70% of the total energy consumption, of which the motor energy consumption accounts for about 60%-70% of the industrial energy consumption. At present, asynchronous motors are the most widely used in the industrial field. The losses of such motors mainly include copper loss, iron loss, mechanical loss, and stray loss. Among them, the stray loss of the cast aluminum rotor accounts for about 1%-3% of the rated power. , although it accounts for a small part of the input power of each motor, but because the squirrel-cage rotor asynchronous motor is widely used and the number is relatively large, the amount of electric energy consumed by this loss is considerable. [0003] There are many types of stray ...
