Original Abstract Submitted
A bearingless motor includes a rotor, a stator for applying support force and torque to the rotor, and a first displacement sensor and a second displacement sensor for detecting a radial position of the rotor. The stator includes a motor winding for generating a magnetic flux having p poles to produce the torque, and a support winding for generating a magnetic flux having p±2 poles or two poles to produce the support force. The first displacement sensor and the second displacement sensor are disposed at positions axially different from each other.
