Research on Permanent Magnet Linear Synchronous Motor with a Special Pole Shape Based on Finite Element Analysis

Abstract:

In this paper, a model of unit motor (16p15s) which is used for vertical elevator has been set up. And a modification of the primary geometry has been presented. In the new geometry, pole shoes are affixed to the primary poles. The finite element analysis (FEA) of various width of pole and different width of pole shoe have been carried out in this paper. The results show that the force profile of the proposed PMLSM has been improved. The minimum force ripple occurs in a suitable width of the pole shoes. And the back EMF constant is analyzed, too.
