针对微型主轴电机提出了一种新结构的混合式（HB）型自轴承电机。所提出的设计将HB型自轴承电机和HB主动磁力轴承结合在公共定子和转子对中，以产生较大的径向力。首先介绍原理和理论背景。然后对气隙磁通进行有限元分析。对所提出的和标准型 RB 自轴承电机的单元方法和径向力进行了比较。最后，进行实验来确认所提出的电机的性能。该电机体积小，能够以较高的转速和较高的扭矩运行。悬浮非常稳定，电机在实际应用中表现出良好的性能。
A new structure of hybrid (HB)-type self-bearing motor is proposed for miniature spindle motors. The proposed design combines the HB-type self-bearing motor and HB active magnetic bearing in the common stator and rotor pair to generate large radial forces. First, the principle and theoretical background are introduced. Then, the air gap flux is analyzed by the finite. element method and radial forces for the proposed and the standard-type - RB self-bearing motors are compared. Finally, experiments are conducted to confirm the performance of the proposed motor. The motor can run at relatively high rotating speed with relatively high torque compared with its small size. The levitation is very stable and the motor indicates good performance for practical application.
