摘　　要：对三相异步电机在不同磁场定向下及六相异步电机在梯形波相电流驱动下的电磁转矩进行了比较分析。比较了两种异步电机在突加相同转矩电流情况下的电磁转矩响应曲线。仿真和实验结果验证了六相异步电机比三相异步电机电磁转矩脉动频率高,幅值小,稳定性强以及相同转矩电流下产生电磁转矩高的特点。This paper compared and analyzed the three-phase asynchronous motor under different magnetic field orientation and six in the asynchronous motor trapezoidal wave phase current driven by the electromagnetic torque. This paper compared the two kinds of asynchronous motor in the process with the same torque emTent situation of the electromagnetic torque response curve. Simulation and experimental results verify the six phase asynchronous motor electromagnetic torque pulsation frequency is higher than three-phase asynchronous motor, the amplitude is small, the stability and the same torque electric shed produce electromagnet- ic torque high characteristic.
