本文提出了一种新的内置式永磁（IPM）电机的转子位置提取方法的载波频率分量信号，来自脉冲宽度调制（PWM）逆变器开关，使用两个参考系。该方法已被用于IPM电机矢量控制，而无需机械转子位置检测器，从开关载波频率（10 kHz）分量电流中提取转子位置角。该方法适用于具有磁凸极、定子绕组正弦分布、由PWM电压型逆变器供电的IPM电机。利用该方法对两台无机械转子位置检测器的IPM电机进行了矢量控制。实验结果表明，良好的动态和稳态性能实现和讨论。
In this paper a novel interior permanent-magnet (IPM) motor's rotor position extraction method from the carrier-frequency component signal, derived from pulsewidth-modulated (PWM) inverter switching, using two reference frames is presented. This method has been utilized for IPM motor vector control without a mechanical rotor position detector, extracting rotor position angle from the switching carrier-frequency (10 kHz) component current. It is effective for IPM motors, which have magnetic saliency, sinusoidal distributed stator winding, and are supplied by a PWM voltage-source inverter. The performance of two IPM motors' vector control without mechanical rotor position detector utilizing this method has been investigated. Experimental results demonstrating good dynamic and steady-state performance achieved are presented and discussed.
