Abstract: Aiming at the influence of the number of hybrid stator core layers on the torque and loss performance of remanufactured motor, the three, five, and sevenlayer hybrid stator core remanufactured motors were analyzed. The loss calculation formula of silicon steel segment and amorphous segment were given, the axial distribution of magnetic flux density and the loss distribution of different layers of hybrid stator cores were analyzed. The axial electromagnetic distribution of unit electromagnetic torque and unit electromagnetic torque of remanufactured motor were calculated, the torque performance of remanufactured motor was analyzed. The remanufactured motor prototype was fabricated by threelayer hybrid stator core and the bench experiment was carried out. The experimental results indicate that the remanufactured motor loss has reduced, torque and efficiency has increased, the feasibility of remanufacturing the motor is verified.
Key words: hybrid stator core; number of layers; output torque; stator core loss
