Analysis of thrust ripple of permanent magnet linear synchronous motor with skewed PMs

2015 18th International Conference on Electrical Machines and Systems (ICEMS), 2015
The thrust ripple of Permanent Magnet Linear Synchronous Motor (PMLSM) at load can reach 10% average thrust, which deteriorates thrust performance. To reduce the thrust ripple, two methods of optimizing the primary length and skewing are widely adopted during PMLSM design. In this paper, the effect of skewing technology is investigated.

Design of thrust ripple minimization by equivalent magnetizing current considering slot effect

IEEE Transactions on Magnetics, 2006
This paper proposes the maximum thrust design of slotted permanent magnet linear synchronous motor (PMLSM) using equivalent magnetizing current method (EMCM) considering slot effect. The genetic algorithm is used for optimization. The objective functions are selected for the maximum thrust and the minimum detent force.
