Paper Title:
Magnetic Levitation Permanent Magnet Linear Synchronous Motor Electromagnetic Analysis
  Abstract

According to the problem of the friction between the mover and the static guide rail in the linear motor drive system of CNC machine tool, this paper proposed the direct magnetic levitation permanent magnet linear synchronous motor to achieve friction-free feed. The mover of the direct magnetic levitation permanent magnet linear motor consists of two sets of windings. One is the thrust winding, which is used to generate electromagnetic thrust, the other is the suspension winding, which is used to generate magnetic levitation force. The mathematical model of the motor’s electromagnetic thrust and levitation force is derived by the Maxwell stress tensor method. Ansoft is used for making finite element analysis of the motor’s electromagnetic thrust and levitation force. The results verified the correctness of the mathematical model. The feasibility of friction-free feed with two-winding direct magnetic levitation permanent magnet synchronous motor is proved.
