In this paper, a novel permanent magnet array is proposed and the magnetic field distribution is evaluated analytically by using magnetic scalar potential. The characteristics of the synchronous permanent magnet planar motor with this novel magnet array such as inductance, back-EMF, and force are calculated by analytical method. The superiority and feasibility of the novel magnet array are verified by comparing with Asakawa array, Chitayat array, and experiment data. Otherwise, the force is developed form 27.77[N] to 30.37[N] by using the method of genetic algorithm.
