Abstract

In this paper, a detection technique of initial rotor position at a standstill in Toroidal Switched Reluctance Motor(TSRM) with built-in interior central pole search coil is proposed. In case search coils are used as a position sensor, it has many advantages like low cost, decrease in the volume, high robust characteristics and wide applications. However, the initial rotor position detection is very difficult because the search coil's EMF is not exist at a standstill. In this paper, a new detection method of initial rotor position is suggested using interior central pole search coil. The simulation and experiment for the proposed method and their results support the validity of the proposed scheme by verifying the operation of a 6/4 TSRM using search coils.
