Abstract:

The interior permanent magnet synchronous motor (IPM) for electric vehicle drive has the disadvantages of high torque ripple and high vibration. Auxiliary slots on the rotor surface can improve the air gap magnetic density sinusoidality by changing the magnetic permeability at different positions of the air gap. The IPM uses a double-layer permanent magnet (PM) rotor structure, and the shape, position, and number of different auxiliary slots affect the torque performance and vibration of the IPM. In this paper, we optimize the rotor auxiliary slot structure of three IPM rotor structures with torque ripple and air gap magnetic density deformation rate (MDDR) as the optimization objectives and summarize the influence of rotor auxiliary slot on the torque performance and vibration of double-layer permanent magnet IPM.
