中文摘要：

Halbach永磁电动机独特的永磁体结构不仅使其磁极磁场呈正弦分布，而且还可以增加气隙磁通密度，削弱转子轭部磁通密度，这使得在提高电动机的功率密度的同时，又可以减小电动机的体积和提高电动机的效率。借助Ansys10．0有限元分析软件对Halbach列以及Halbach电动机进行了深入研究，有限元分析结果和样机的实验数据说明了Halbach电动机的优越性。

英文摘要：

Halbach motor is a new type permanent magnetic （PM） motor. A sinusoidal field is produced by the special distribution of permanent magnets. The field can increase the air-gap flux while decrease the rotor yoke flux. The result can improve power density, increase efficiency and reduce volume of the motor. Insight research on Halbach array and Halbach motor have been done by finite element analysis of Ansys10. 0, Finite element analysis and experiment results prove Halbach motor has more advantages than traditional PM motor.
