利用笼形转子的各向异性来确定感应电机转子的角位置。由脉宽控制逆变器产生的开关瞬态作为测试信号。利用三个逆变器端电流的响应，得到一个准瞬时转子位置信号。通过三相电机电缆测量电流导数，在逆变器处检测位置。该方法不需要额外的电线连接。它适用于定子绕组呈直角或三角形连接的感应电动机。这些结果得到了实验装置测量结果的支持。
The anisotropy of a cage rotor is utilized to determine the angular position of the rotor in an induction machine. The switching transients generated by a pulsewidth-controlled inverter serve as test signals. The response of the three-inverter terminal currents is exploited to derive a quasi-instantaneous rotor position signal. The position is sensed at the inverter through the three-phase motor cable by measuring the current derivatives. The method does not require additional wire connections. It is applicable to induction motors having stator windings connected either in wye or in delta. The results are supported by measurements from an experimental setup.
