Investigation of Static Characteristics in Six-Phase Switched Reluctance Motors under Different Winding Connections

Abstract

The effect of the winding connections on the static torque in six-phase switched reluctance motors (SRMs) is investigated in this paper. Different winding connections for the six-phase SRMs are shown and compared. Under the conditions of different winding connections, the self-inductance and mutual inductance of a six-phase SRM are compared and analyzed. Six-phase SRMs can be running in two-phase excitation mode and three-phase excitation mode, and in these two modes, the static torque characteristics with different poles polarities arrangements are compared and analyzed. The comparison of the static torque in a six-phase SRM with different winding connections is obtained by the Maxwell 2D and experiments. Based on the results, an optimal winding connection mode for starting stage of the six-phase SRMs is proposed.
