Abstract

This paper presents a new method of detecting rotor position in Toroidal Switched Reluctance Motor(TSRM). In this paper, low cost and robust characteristics of rotor position detection method are focused in order to compensate for disadvantage of general sensors. Search coils wound through the hole of the stator poles are used for detection of the rotor position in TSRM. Rotor position detection is achieved through electromotive force patterns induced by time-varying flux linkage in the search coils and then adequate phase is excited for drive. The initial rotor position estimation method is also described. The validity of the method is verified by experimental results.
