介绍了双向轴向间隙组合电机轴承的设计特点，其中平盘电机同时具有旋转和轴向位置控制能力。该电机由盘形转子组成，转子两侧各有一个定子。转子的轴向运动受到主动控制，而其他轴则受到额外的被动或主动径向磁轴承的约束。每个定子在气隙中产生旋转磁通量，以产生电机扭矩。通过改变旋转磁通的振幅来控制轴向力。对永磁电机和感应电机版本都进行了理论分析和实验测试。结果证明了其能够同时提供电机和磁力轴承的功能。
Introduces the design characteristics of a bidirectional axial gap combined motor-bearing where the flat disc motor has both rotation and axial position control capability. This motor consists of a disc rotor with a stator on each side of the rotor. The axial motion of the rotor is actively controlled while the other axes are constrained by additional passive or active radial magnetic bearings. Each stator produces a rotating magnetic flux in the air gap, to generate the motor torque. The axial force is controlled by changing the amplitude of the rotating flux. Both permanent-magnet motor and induction motor versions were analyzed theoretically and tested experimentally. The results demonstrated the capability of providing both the functions of a motor and a magnetic bearing.
