چکیده
In this paper, an analytical analysis is presented to calculate air gap flux density distribution, thrust and efficiency in air-core permanent magnet linear synchronous motor with Halbach array based on Maxwell equations. In order to improve mean thrust, thrust ripple, magnet and copper consumption, the main design parameters of analyzed machine are optimized by using genetic algorithm in an appropriate objective function. The results show an enhancement in motor performance. Finally, we have used 2-D nonlinear time stepping finite element method to demonstrate validity of the analytical analysis and optimization method.

In the permanent magnet linear synchronous motor (PMLSM), force ripple is harmful, useless and disturbing. The force ripple is basically composed of two components: detent force and mutual force ripple. This force is influenced by the geometric parameters of the permanent magnet (PM) motors; such as width, thickness and length of the magnet poles, length and thickness of the rotor and stato...
