Abstract

The invention discloses a double-cage rotor punch, a double-cage rotor and a motor, wherein the double-cage rotor punch has a circular structure, and the double-cage rotor punch of the circular structure is provided with A plurality of rotor slots, the plurality of rotor slots are a combination of any two or three slot structures among double-cage convex slots, double-cage trapezoidal slots and double-cage knife-shaped slots. The invention reduces the starting current and slot leakage reactance of the motor, improves the skin effect and rotating speed of the motor, and enhances the starting ability and operation stability of the motor.

Description

technical field [0001] The invention relates to the field of electric motors, in particular to a double-cage rotor punch, a double-cage rotor with the double-cage rotor punch, and a motor with the double-cage rotor. Background technique [0002] The rotor is an important part of the motor. It consists of a rotor iron core, a rotor winding and a rotating shaft. Its function is to generate an induced electromotive force or an induced current under the action of a rotating magnetic field. The rotor core is usually formed by laminating multiple rotor punching sheets, and each rotor punching sheet is provided with a plurality of rotor slots. Most of the rotor grooves in the traditional rotor punching piece are pear-shaped grooves, and their structure is single, which is not conducive to the improvement of the overall performance of the motor. SUMMARY OF THE INVENTION [0003] The invention provides a double-cage rotor punching piece, a double-cage rotor and a motor, which effe...
