Composite rotor punching sheet, permanent magnet motor and vehicle

Abstract

The invention discloses a composite rotor punching sheet, a permanent magnet motor and a vehicle. The invention provides a composite rotor punching sheet. A first magnetic steel groove and a second magnetic steel groove are formed in a rotor punching sheet; the first magnetic steel and the second magnetic steel are correspondingly detachable; wherein the rotating speed, the torque and the power are required by a whole vehicle driving system assembly. Determining whether the first magnetic steel is inserted into the first magnetic steel groove; the second magnetic steel is inserted into the second magnetic steel groove; different assembly performance requirements of the new energy motor can be finally met; and when different assembly performance requirements of the new energy motor are met,universalization and serialization can be achieved without redesigning the electromagnetism, so that the research, development and production periods of the motor stator and rotor punching sheets aregreatly shortened. Meanwhile, the die cost is reduced, the material control and purchase cost is reduced, and the operation efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a composite rotor punch, a permanent magnet motor and a vehicle. Background technique [0002] The motor is composed of stator, rotor, machine base, end cover, etc. According to the working power supply, structure and principle of the motor, the motor is divided into many types. The permanent magnet assisted synchronous reluctance motor is widely used in servo drive and other aspects because of its advantages of high energy density, good work efficiency and low noise. In the motor, the iron core part of the stator and the iron core part of the rotor are both the magnetic conduction parts of the motor, which play a vital role in the working performance of the motor. Its shape, size, and technological level determine the noise, vibration, temperature rise, and various performance indicators of the motor. The stator core and rotor core of the motor are formed by laminating many sta...
