Study on equivalent circuit of doubly fed brushless reluctance machine based on frequency referring

This paper presents an equivalent circuit of doubly-fed brushless reluctance machine (DFRM) based on frequency referring, which solves the problem that vectors relative to the power winding and control winding are not stationary each other. The proposed equivalent circuit makes the relationship between the main winding and control winding clear and easy to be used for analysis of the steady state behavior of a DFRM. The application example and simulation results of the equivalent circuit are presented in the paper.
