| 摘 要： | 该文比较了ALA+PM转子同步电机和传统的PMSM电机的转矩特性,前者随定子磁链的增大,转矩与负载角始终保持线性关系,不像后者需要约束条件。直接转矩控制是ALA+PM转子同步电机最好的控制方式,但定子磁链大于永磁磁链和小于永磁磁链,都会使定子电流增大,采用最大转矩/电流比(MTPA)方式给定定子磁链不会产生额外损耗。

| Abstract: | This paper compares the torque characteristics of the ALA+PM rotor synchronous motor with one of the conventional PMSM, the former holds linearity relationship with the increase of stator flux linkage, the later needs restrict condition. The direct torque control(DTC) is the best control method for ALA+PM rotor synchronous motor, but the stator current can increase if the stator flux linkage is bigger or less than magnet flux linkage, It can’t produce extra loss if MTPA is used. |
