AlNiCo permanent magnet was used in doubly salient permanent magnet motor with nonrareearth (NREDSPM) to replace traditional rare earth permanent magnet, which could reduce the production cost of the motor, and the airgap magnetic field of NREDSPM could be adjusted by the magnetizing windings to improve the performance of the motor. However, due to the influence of the motor parameters, a large number of harmonics existed in the phase current of NREDSPM motor, which seriously affected the efficiency and stability of the motor. To solve this problem, a current loop control method based on PI controller parallel resonant regulator was adopted. The method was simple and easy to implement, and does not need to increase the hardware circuit cost, could effectively suppress the current harmonics. Experiments were finished on a 1.25 kW NREDSPM experimental platform, and the effectiveness of the method was verified by the experimental results.
