利用笼型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。三个逆变器端子电流的响应被利用来导出准瞬时转子位置信号。通过测量电流导数，通过三相电机电缆在逆变器处感测位置。该方法不需要额外的导线连接。它适用于定子绕组呈Y形或三角形连接的感应电动机。结果支持从实验装置的测量。
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 3-phase motor cable by measuring the current derivatives. The method does not require additional wire connections. It is applicable to induction motors having the stator windings connected either in wye or in delta. The results are supported by measurements from an experimental setup.
