Abstract

The invention discloses a double-cage rotor punching sheet, a double-cage rotor and a motor. The double-cage rotor punching sheet has a ring-shaped structure. The double-cage rotor punching sheet with the ring-shaped structure is provided with multiple rotor grooves along the circumferential direction, and the multiple rotor grooves are a combination of any two or three selected from double-cage convex grooves, double-cage ladder-shaped grooves and double-cage knife-shaped grooves. Starting current and groove leakage reactance of the motor can be reduced, skin effects and the rotation speed of the motor are enhanced, and the starting ability and the operation stability of the motor are enhanced.

Description

technical field [0001] The invention relates to the field of 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, which is composed of the rotor core, the rotor winding and the rotating shaft. Its function is to generate induced electromotive force or induced current under the action of the rotating magnetic field. The rotor core is usually formed by laminating multiple rotor punches, and each rotor punch is provided with a plurality of rotor slots. Most of the rotor slots in traditional rotor punching are pear-shaped slots, which have a single structure, which is not conducive to the improvement of the overall performance of the motor. Contents of the invention [0003] The invention provides a double-cage rotor lamination, a double-cage rotor and a motor, which effectively improves the overall performance...
