ABSTRACT:
A system for detecting the position of a rotor for a switched reluctance (SR) machine having an irregular pole configuration. The system does not require the use of a conventional sensing device, and provides accurate position information, without disrupting operation of the machine. A voltage ratio is used to infer the position of the rotor relative to the stator.
