摘要：
The vibration and noise performance of V-type interior permanent magnet (IPM) machines can be improved by reducing cogging torque. Based on the analysis of cogging torque symmetry, the influence of rotor parameters on the cogging torque symmetry of V-type IPM machines was studied, and a set of optimal parameter combinations were determined. The symmetry of the cogging torque was increased, and the cogging torque of the motor was reduced significantly by combining rotor step-skew method. Through the 2-dimensional and 3-dimensional finite element simulation, the influence of the improved rotor parameter combination on the motor performance was analyzed firstly, and then the feasibility and effectiveness of the proposed method was verified. It is found that, by improving cogging torque symmetry, the weakened effect of cogging torque for V-type IPM motors is nearly doubled compared with that before optimization, with litter influence on the motor performance. © 2020, Harbin University of Science and Technology Publication.
