Proposal of a permanent magnet hybrid type axial magnetically levitated motor

A permanent magnet hybrid type axial magnetically levitated motor is proposed. The motor consists of a spherical permanent magnet and an axial type bearing-less motor that has tilt control function. The rotor has two permanent magnets on one side, and the motor stator has eight poles, which include eight concentrated windings. The operating principle was investigated by numerical analysis. It was verified that the proposed motor can control the translational motion, inclinational motion and rotational motion independently.
