| Abstract: | In order to improve the sinusoidal waveform of surface-mounted permanent magnet motor,cut down its harmonic component and increase its efficiency and power index,this paper put forward a sinusoidal magnetic pole modulation permanent magnet motor.Rotor iron core surface was composed of a number of small arrayal magnetic blocks.Its width height and interval between arrayed magnets met a modulation relationship.Air-gap magnet field waveform was generated more closely to sinusoidal waveform by setting the struc... |
