摘　　要：对一种新型薄片式永磁同步无轴承电机的设计进行了分析。从无轴承电机和普通永磁电机的基本原理出发,通过对各种转子结构的比较,研究它们的磁场分布,提出了一套优化的转子结构。与传统的电机相比,内转子薄片式永磁同步无轴承电机的结构比较特殊,它的运行原理、分析和设计与普通无轴承电机有着较大的不同且应用前景广阔。着重阐述了内转子薄片式永磁同步无轴承电机的工作原理和控制方法。The design of a new type of self-bearing slice PM motor is analysed. Based on the basic principle and theory of self-bearing motor and traditional PM motor,this paper make a comparison between some different kinds of rotor structure by probing into their flux distribution, then an optimized rotor structure is proposed. Due to its unique structure,self-bearing slice motor with innerrotor is very different from traditional PM motor as far as its function theory, analysis, design as well as its great potentiality for application is concerned. The function theory and control technique of self-bearing slice PM motor with inner rotor is also expatiated in this paper.
