Problems solved by technology

[0002] The rotor is an important part of the motor. The rotor is divided into a winding rotor and a double-cage rotor. The double-cage rotor is composed of a double-cage rotor core, guide bars and end rings. Under the action, induced electromotive force or induced current is generated. Among them, the double-cage rotor core is formed by laminating several double-cage rotor punches. Currently, there are two types of double-cage rotor punches on the market. Refer to Figure 1-2 , one is a single-cage rotor punch, which includes a single layer of evenly distributed rotor slots 112, but results in a narrow and long bar structure of the single-cage rotor to which the single-cage rotor punch is applied. ;refer to Figure 3-4 , and the other is the traditional double-cage rotor punching. The traditional double-cage rotor punching includes double-layered rotor slots 112 that are evenly distributed in the radial direction, but the two layers of rotor slots 112 are connected to each other. , the magnetic field 120 cannot pass between the two layers of rotor slo

Abstract

The invention discloses a double-cage rotor punching sheet, a double-cage rotor and a motor. The double-cage rotor punching sheet comprises a circular silicon steel sheet. Each silicon steel sheet isprovided with two layers of rotor grooves. The two layers of rotor grooves are spaced along the radial direction of the silicon steel sheet. The two layers of rotor grooves comprise an outer-layer rotor groove and an inner-layer rotor groove. The outer-layer rotor grooves and the inner-layer rotor grooves respectively comprise a plurality of first rotor grooves and a plurality of second rotor grooves. The first rotor grooves and the second rotor grooves are formed in the circumferential direction of the silicon steel sheet, the first rotor grooves and the second rotor grooves are formed in a staggered mode in the circumferential direction of the silicon steel sheet, and the first rotor grooves and the second rotor grooves, the first rotor grooves and the second rotor grooves are not communicated. The double-cage rotor punching sheet has the beneficial effects that a magnetic field can pass through the gap between the two layers of rotor grooves, the magnetic permeability of the double-cage rotor punching sheet is improved, and the performance and the operation efficiency of a motor are improved.
