This paper provided a novel magnet arrayed permanent magnet synchronous motor with self-starting function and high efficiency. The magnetic pole which is affixed in rotor surface is composed of a number of small array magnetic blocks; its width, height and the interval between arrayed magnets meet a modulation relationship. So magnetic field generated by arrayed magnets more closely to sinusoidal waveform via reasonable setting the structure and location of the rotor and poles. At the same time, using the remaining space between the array magnets to set damping coils that generates asynchronous electro-magnetic torque and enhanced the magnet arrayed permanent magnet synchronous motor self-starting capability. Then magnetic field analysis using ansoft program are verified by experiment results.
