Built-in permanent magnet synchronous motor rotor punching sheet structure

A built-in permanent magnet synchronous motor rotor punching sheet structure disclosed by the present invention comprises a rotor punching sheet body and magnetic steel, the rotor punching sheet body is provided with a plurality of magnetic steel structure groups, the magnetic steel structure groups are uniformly distributed along the circumferential direction of the rotor punching sheet body, and the number of the magnetic steel structure groups is equal to the number of poles of a motor. The magnetic steel is installed in the magnetic steel structure group. According to the rotor punching sheet structure, the problem that in the prior art, magnetic steel is prone to demagnetization can be effectively solved, by adding the magnetic steel limiting structure, the demagnetization resistance of the magnetic steel is improved, the performance of a motor is improved, the service life of the motor is prolonged, and the cost of the motor is reduced. 本发明公开了一种内置式永磁同步电机转子冲片结构，包括转子冲片本体和磁钢，所述转子冲片本体上设有多个磁钢结构组，磁钢结构组沿转子冲片本体
