| 摘 要： | 定子永磁型双凸极非稀土永磁电机(NREDSPM)采用剩磁较高的铝镍钴(AlNiCo)永磁代替传统的稀土永磁,降低电机制作成本的同时也可配合磁化绕组对电机气隙磁场进行调节,使电机获得较好的性能。但受电机本体参数影响,NREDSPM在运行时相电流中含有大量的谐波,严重影响电机的效率和稳定性。为解决此问题,采用了一种PI控制器并联谐振调节器的电流环控制方法。该方法结构简单,易于实现,且无需增加硬件成本,可对电流谐波进行有效抑制。一台1.25 kW的NREDSPM样机在试验平台上进行了试验,试验结果验证了所用方法的有效性。

| Abstract: | 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. |
