摘 要:针对分数槽配合电机的气隙磁场谐波次数过多,容易产生振动和噪声问题,采用磁路计算和有限元分析相结合的方法,设计了一台8 极24 槽、11.8 kW、额定转速1 500 r/min 的整数槽配合的永磁同步电动机。给出了确定电机主要尺寸的方法,利用Ansys Maxwell 软件对电机空载磁场、反电势、齿槽转矩、电机负载性能进行了仿真分析与计算。样机试验结果表明达到了设计要求,与仿真结果误差在5% 以内,验证了设计和仿真的准确性。

Abstract: It is easy to generate vibration and noise if there are overabounded times of air gap magnetic field harmonics in fractional slot combination motor. Aiming at the above problem, this paper adopted the combined method of magnetic circuit calculation and finite element to design a permanent magnetic synchronous motor with integer slot combination of 8 poles, 24 slots, 11 .8 kW, rated rotation speed of 15 00 r/min. Main dimensions of the motor was given. By using Ansys Maxwell software, simulation analysis and calculation were carried out for no-load motor magnetic field, counter electromotive force, cogging torque and motor load performance. Sample machine test result shows that the motor has reached design requirements. Compared with the simulation result, the error is less than 5%, which verifies the correctness of the design and simulation.
         Key words: permanent synchronous motor; fractional slot combination; integer slot combination; vibration; noise
