The Simulation of Novel Bearingless Consequent-pole Slice Motor

In the bearingless slice motor, two radial degrees magnetic levitation is realized by utilizing bearingless technology. Meanwhile three out of five degrees can be stabilized passively. In this paper, a novel bearingless slice motor is proposed. The levitation control is independent of the drive-winding magnetic field. This paper introduces the principle of radial force, as well as the advantages of the motor. Furthermore, the equations of radial levitation force are given. At last, the main levitation characteristics of the novel machine are analyzed by using 2D/3D finite element analysis in detail. The results verify the validity of the proposed motor.
