| 摘 要： | 为了削弱永磁电机齿槽转矩,提高电机气隙磁密,改善气隙磁场分布,采用分段式Halbach阵列磁体结构,使永磁体获得理想的单边磁场。利用Maxwell软件,建立电机二维有限元分析模型,计算空载时电机的磁力线分布,获得电机气隙磁密和齿槽转矩等电磁特性,并与传统径向充磁磁体电机进行对比分析。研究结果表明,该方法能有效削减齿槽转矩,提高磁密幅值,增强磁密正弦性。

| Abstract: | In order to reduce the cogging torque of the permanent magnet motor (PMM), increase the magnetic induction density in air-gap and improve the air-gap magnetic field distribution, segmented Halbach array magnet is used to obtain the ideal one-sided magnetic field. By finite element analysis of Maxwell Software for 2-D moeling of the machine, the no-load distribution of the magnetic field lines was calculated to obtain the electromagnetic parameters like air-gap magnetic induction density and cogging torque, and was compared with that of the traditional radial magnetization motor. The study shows that this method can effectively reduce the cogging torque, and increase the amplitude and sinusoidal property of flux density. |
