摘　　要：提出一种新型Halbach次级结构的无铁心永磁同步直线电机,介绍了该新型直线电机的结构和原理,利用矢量磁位和边界条件对Halbach永磁阵列所产生的磁场进行解析分析,得到气隙磁通密度的表达式,建立直线电机的数学模型。通过研究分析,设计制造一台样机并进行相关实验研究,通过对比实验和仿真结果,来验证解析设计的合理性。A novel ironless synchronous permanent magnet linear motor with Halbach array is proposed. The operation principle and structure of this linear motor are introduced. Based on magnetic vector potential equation and boundary conditions, flux density distribution induced by the permanent magnet array is analysed analytically. And then the expression of the air-gap flux density distribution is derived. In our laboratory, a prototype machine was designed and manufactured. And some experimental study was carried out, which validate the analytical and simulated results.
