Problems solved by technology

[0006] 1) Increase the rotor inertia, and the response speed of the motor will decrease
[0007] 2), increased production costs and reduced production efficiency
[0008] 3) The magnetic steel pressure plate will block the magnetic isolation bridge hole and hinder the air flow, which is not conducive to the heat dissipation of the rotor
[0009] 2. The heat dissipation efficiency is poor, which affects the motor efficiency
[0010] 3. The use of magnetic steel is large, and the cost is high

Abstract

The invention discloses a method for obtaining the radial length of an IPM motor rotor and a strip-shaped heat-conducting material. Each rotor core slot is arranged radially; each rotor core slot is equipped with magnetic steel and strip-shaped heat-conducting material; wherein, the strip-shaped heat-conducting material faces the side of the rotating shaft, and the strip-shaped heat-conducting material is the coefficient of thermal conductivity and expansion Coefficients are greater than the non-magnetic material of silicon steel sheet. The strip-shaped heat-conducting material is preferably an aluminum strip. A magnetic isolation bridge is arranged on the rotor iron core between two adjacent strips of heat conducting material. The application has the reliability of high-speed operation when there is no end magnetic steel baffle plate, enhances the heat dissipation effect of the rotor and reduces the cost of the magnetic steel of the motor.

Description

technical field [0001] The invention relates to the field of permanent magnet synchronous motors, in particular to a method for obtaining the radial length of an IPM motor rotor and a strip-shaped heat-conducting material. Background technique [0002] As China vigorously promotes the process of Industry 4.0, a large number of enterprises have been driven from labor-intensive enterprises to highly automated enterprises; as the degree of automation of enterprises continues to deepen, the requirements for industrial permanent magnet synchronous motors are becoming more and more stringent. A simple SPM motor turns to an IPM motor with a more compact structure and better overload capacity; so the design of the rotor structure of the IPM motor becomes the key to the entire motor. [0003] The existing IPM motor rotor structure has the following deficiencies and needs to be improved: [0004] 1. The end face of the existing rotor needs to be added with a magnetic steel pressure p...
