Calculation of Steady State Parameter in Permanent Magnet Linear Synchronous Motors by Analysis Method and FEM

Article Preview

Abstract:

The steady state parameters of permanent magnet linear synchronous motor (PMLSM) has an important influence on the performance of the motor. Based on a linear permanent magnet horizontal motion synchronous motor, the paper adopts multi-layered model method to give the formulas of the air-gap flux density that the permanent magnet and armature winding act on alone, no-load back electromotive force, the thrust force in steady-state operation and vector control of thrust in the dq model equation, then compute the value of these parameters according to the formulas, and the finite element method (FEM) to each parameter is validated, the simulation curve is given, the experimental value is also done to prove the exactness of the two methods.
