提出了一种无轴承片式电机的新结构，用于悬浮和旋转环形实心钢磁阻转子。转子直径50毫米，外表面有显著特征。对称的Halbach磁体阵列安装在定子齿的尖端，在转子周围建立一个同极偏置磁通。偏置磁通在平面外倾斜和轴向平移时被动稳定转子，而通过反馈控制主动稳定转子的径向平移。转子凸度在空间上调制气隙偏置磁通，从而产生类似于永磁同步电机的扭矩-电流关系。我们已经设计、制造和测试了无轴承电机和控制系统的原型。样机的转矩常数为14.9 mNm/A，最大转速为5500转/分，悬浮带宽为84赫兹，相位裕度为11.3°。额定扭矩和转速分别为26.8MNM和3486rpm，轴向和倾斜被动刚度分别为15.3N/mm和34.4MNM/deg。
We present a new configuration of bearingless slice motor that levitates and rotates a ring-shaped solid steel reluctance rotor. The rotor is 50 mm in diameter and has salient features on the outer surface. Symmetric sets of Halbach magnet arrays, mounted on the tips of stator teeth, establish a homopolar bias flux around the rotor. The bias flux passively stabilizes the rotor in the out-of-plane tilts and axial translation, whereas the rotor’s radial translations are actively stabilized by feedback control. The rotor saliencies spatially modulate the air-gap bias flux such that the resulting torque-current relationship is similar to that of permanent-magnet synchronous machines. We have designed, built, and tested a prototype bearingless motor and control system. The prototype system achieves a torque constant of 14.9mNm/A, maximum speed of 5500 rpm, and suspension bandwidth of 84 Hz with a phase margin of 11.3 deg. The rated torque and speed are 26.8 mNm and 3486 rpm, and the axial and tilting passive stiffnesses are 15.3 N/mm and 34.4 mNm/deg.
