摘　　要：介绍了无轴承薄片电动机的基本结构和工作原理,用转子气隙磁场积分的方法推导出电机悬浮力和电磁转矩数学模型。利用ANSYS有限元分析软件,分析了电机转子圆周面上径向悬浮力的分布,验证了径向悬浮力产生机理和数学模型准确性,分析了径向悬浮力和转矩的特性,为电机控制系统的构建提供了理论依据。The basic structure and principle of bearingless permanent slice motors was introduced, and the mathematical models of radial suspension force and electromagnetic torque were deduced with the integral method of the rotor air-gap. The distribution of radial suspension force acting on the rotor circle surface was analyzed by using the finite element analysis software, namely ANSYS ,which testified the generating principle of radial suspension force and the veracity of math models. The characteristic of the radial suspension force and torque was analyzed, which provided the theoretical basis for the construction of control system.
