同期型および誘導型磁気浮上回転モータの研究 Research on Synchronous Type and Induction Type Levitated Rotating Motor
A general solution of levitation control to PM synchronous type and induction type rotating motor is presented. It is intended that the rotor has the levitation force which is controlled by the stator magnetic flux. The rotor of the permanent magnet motor is assumed to have the sinusoidally distributed magnetic poles along the axial surface, while the rotor of the induction motor is assumed to have the uniform magnetic property. The inner wall of the stator is also assumed to have a current sheet, which can produce an arbitrary current distribution. The same number of magnetic pole gives the rotating torque to the rotor, while the plus minus two magnetic pole of the motoring control produces a pure drag force to the rotor. By controlling the magnitude and phase of the plus minus two pole current distribution relative to the motoring magnetic pole, the drag force can be controlled in the radial coordinate. This general solution is experimentally confirmed by using a simple experimental setup and the load test is conducted and reported.
