Abstract: In this paper, a doubleclosed loop control system of a novel transverseflux permanent magnet motor was designed and realized to improve speed regulating and stability of the motor. In consideration of much longer commutation process, phase advance commutation was brought to enlarge torque per current and to increase the efficiency of the motor. Results of simulations and experiments show that the control system can obviously improve the performance of the motor.
Key words: transverseflux permanent magnet machine; BLDCM mode; doubleclosed loop control; phase advance commutation
