提出了一种新型的五自由度主动控制自轴承电机，该电机结合了电机、两个径向电磁轴承和一个轴向电磁轴承的功能，同时实现了更小的尺寸和更高的性能。本文研究了五自由度可控自轴承电机的磁悬浮特性。首先，径向控制性能的开发自轴承电机的径向实验装置进行评估。其次，通过五自由度实验装置，对倾斜控制性能和五自由度主动控制性能进行了评价。最后，在五自由度的频率响应测量与非接触悬浮。五自由度控制的自轴承电机产生足够的径向力和倾斜控制扭矩，以克服径向负刚度和稳定转子。在频率响应中观察到足够的频率带宽，并且自轴承电机成功地抑制了谐振频率处的振动。
A novel 5-DOF actively controlled self-bearing motor that combines the functions of a motor, two radial AMBs, and an axial AMB has been developed to achieve smaller size and higher performance simultaneously. In this paper, magnetic suspension performance of the 5-DOF controlled self-bearing motor is reported. First, radial control performance of the developed self-bearing motor is evaluated by the radial experimental setup. Next, tilt control performance and 5-DOF active control performance are evaluated by the 5-DOF experimental setup. Finally, the frequency response in the 5-DOF is measured with the contact-free levitation. The 5-DOF controlled self-bearing motor produced sufficient radial force and tilt control torque to overcome the radial negative stiffness and to stabilize the rotor. The sufficient frequency bandwidth was observed in the frequency response and the self-bearing motor successfully suppressed vibration at the resonant frequencies.
