Thrust Study of a Novel PM Linear Synchronous Motor

Abstract:

This paper presents an analysis of a new type of permanent magnet excited transverse flux linear synchronous motor (PMTFLSM). This linear motor achieves a high thrust from its novel design and fabric. Its translator consists of cross-shaped core sets. Considering parameters such as magnet dimension, pole pitch, and tooth width of the translator, the effected thrust is analyzed and simulated with a 2D model of our PMTFLSM using the finite element method. Extensive simulations were conducted to investigate how the motor performs under a variety of parameter settings. Accordingly, motor characteristics are identified whereby an optimal combination of parameter values can be found. The new findings are then fed back to our motor design to validate performance improvement.
