摘　　要：提出一种新型复合电流驱动的永磁同步平面电机,简单介绍了该平面电机的结构和原理,利用标量磁位和边界条件对永磁阵列所产生的磁场进行解析分析,分别推导出电磁力和反电动势的表达式,建立电机的数学模型。在实验室条件下,设计制造一台样机并进行相关实验研究,通过对比试验和仿真结果,验证了解析设计的合理性。A novel composite-current driven synchronous permanent magnet planar motor is proposed.The operation principle and structure of this planar motor are introduced.Based on scalar magnetic potential equation and boundary conditions,flux density distribution induced by the permanent magnet array is analyzed analytically.And then the expressions of the forces and back-EMF are derived respectively.In our laboratory,a prototype machine is designed and manufactured.And some experimental study is carried out,which validate the analytical and simulated results.
