This paper presents the characteristic of torque and suspension force in a d-q axis current control bearingless motor. It is derived based on Finite Element (FE) analysis using a simulation software, and furthermore compared with the computed results of the conventional bearingless motors, which two kinds of windings for motor drive and magnetic suspension are wound in a stator core. Three types of the conventional bearingless motor with n-pole motor winding and (n +- 2)-pole suspension winding are taken up and their computed results of the torque and suspension force are discussed in detail. As a result, the superiority of the proposed d-q axis current control bearingless motor is found.
