Abstract
This paper deals with the characteristics analysis and the normal force minimization of a synchronous permanent magnet planar motor (SPMPM) with a Halbach magnet array. The characteristics such as flux density, back-EMF and thrust are evaluated and compared with experimental values. The measured values of back-EMF are in good agreement with the simulation ones, but the experimental results of thrust are much smaller than those of simulation due to the friction force generated by the normal force. The normal force is minimized by using a genetic algorithm, and it is greatly decreased from 672.83 N to 144.24 N.
