摘要

针对低速大转矩切向结构永磁同步电机中磁钢尺寸对性能的影响进行研究。提出一种“工”字形排布的磁钢径向并联组合优化方案。在保证电机磁钢轴向长度和体积不变前提下，分析磁钢磁化方向长度变化对电机性能的影响。分析表明：磁钢的磁化方向长度在一定范围内增加可降低磁钢漏磁、增大反电动势和降低转矩波动；但磁钢的磁化方向长度过度增加会大大降低电机磁通面积，使得电机反电动势不增反降。在此基础上，提出一种降低磁钢漏磁、增大反电动势和降低转矩波动的三块磁钢径向并联组合的“工”字形排布方案：近气隙侧和近隔磁槽侧磁钢槽内分别插入磁化方向长度短、径向宽度窄的磁钢以降低近气隙侧和近隔磁套侧磁钢漏磁；近气隙侧磁钢和近隔磁槽侧磁钢之间采用磁化方向长度较短的磁钢以保证磁钢磁通面积降低得不多。通过仿真实验验证所提方案的可行性。

Abstract：

The performance impact of permanent magnet size in spoke-type permanent magnet synchronous motor with low speed and high torque is studied. And the scheme of radial parallel permanent magnet with ‘工’-shape for spoke-type permanent magnet synchronous motor is proposed. With the axial length and the volume of the magnet is maintained, the influence of the magnetization length on motor performance is analyzed. With the magnetization length increased in a certain range, the analyzed result proved that the leakage coefficient and the torque fluctuation can be reduced, the back-electromotive force can be increased. However, excessive increased magnetization length will reduce the back-electromotive force with the magnetic flux area sharp decreased. On this basis, the scheme of radial parallel permanent magnet with ‘工’-shape is proposed to reduced the leakage coefficient, cogging torque and increase the electromotive force:the magnets with longer magnetization length and thinner radical size are inserted into the near air gap side and the near magnetic sleeve side magnet slot respectively to reduce the leakage coefficient; the magnet with shorter magnetization length and wider radical size is inserted between the near air gap side and the near magnetic sleeve side magnet to ensure the magnetic flux area of the magnet modest decreased. The feasibility of the proposed scheme is verified by simulation and experiment.

Key words： Spoke-type permanent magnet synchronous motor(PMSM) the size of permanent magnet magnetization length leakage coefficient radial parallel permanent magnet
