Abstract:To improve the environmental adaptability of the position sensors and broaden the application fields of the switched reluctance motor(SRM), this paper presents that the SRM can be used as a rotor position sensor to provide real-time rotor position for the other SRM that need to be controlled. In this paper, taking the 12/8 structure SRM as an example, by injecting high-frequency diagnostic pulses, the resultant pulse current can be modulated using the amplitude modulation technique(AM). The modulated current waves can be adjusted through signal conditioning circuits and the cross comparators to estimate the position index pulses. The detecting circuits are designed and at last. The experiments verified the validation of the method.
