摘　　要：最小定子电流控制技术可以使电机在同样的负载下使定子电流达到最小,从而可以减小电机和逆变器的损耗,提高整个系统的效率,同时也减小了逆变器的电流应力,提高电机输出转矩的能力。主要对基于转子磁场定向的异步电机最小定子电流控制进行了分析讨论,并建立数学模型进行仿真和实验。Under the minimum stator current control strategy, the stator current of asynchronous motor can be at its minimum point with respect to any given, so it decreases the energy loss of the motor and the inverter which links to the motor, and thus it increases the efficiency of the whole system. The minimum stator current control strategy of asynchronous motor based on rotor flux-oriented control are analyzed and simulated in this paper.
