Abstract: Disc permanent magnet synchronous AC speed regulating motor is gradually used in petroleum industry due to its special structure and excellent performance.A disc permanent magnet synchronous AC speed regulating motor applied to top drive device with double stators and single rotor was presented in this paper.Besides，noload and load state was discussed，two spiral channels were designed and compared in the temperature field，and the main structure was analyzed by finite element method.Optimized electromagnetic scheme，compact structure design and unique spiral channel cooling method were adoped.Prototype machine experiment shows that it has good frequency control of motor speed. It can build the stable foundation for later research and development of same type motor which has higher power.
Key words: disc permanent magnet synchronous AC speed regulating motor；structure；electromagnetic；cooling
