Abstract
A new sensorless method for 8/6 Switched Reluctance Motor is presented in this paper. Inductance of two adjacent unexcited phases are used to generate two orthogonal vectors and are used for rotor position estimation. Inductance of unexcited phases are estimated from current slope resulting from pulse injection. This method can estimate rotor position from standstill to high speed without any prior knowledge about magnetic characteristics of Switched Reluctance Motor. As this method uses only inductance of unexcited phases, saturation will not affect the estimation accuracy.
