摘要
介绍了一种新型电动车用永磁电机宽调速驱动系统。在采用新型电机结构的基础上,基于标量算法的快速电流追踪控制满足了高性能的调速要求。在高速下,利用变压器电势来削弱电机旋转电势,从而实现了高于基速的恒功率运行,扩展了电机的调速范围。
A novel Wide-range speed control system for PM motor is introduced in the paper. Based on the novel motor structure and high-speed current hysteresis controller, high performance speed control is achieved. In the high-speed regin, permanent power operation above the based speed is realized by employing the concept of curbing the EMF through transformer electromotive force.
