d-q equivalent circuit representation of three-phase flux reversal machine with full pitch winding

In this paper a d-q equivalent circuit for flux reversal machine (FRM) is proposed. In order to improve the power density, full pitch winding is proposed. FRM with this winding winding (FPFRM) is compared with conventional concentrated stator pole winding FRM (CSPFRM). The output power of FPFRM is twice that of CSPFRM for the same machine dimensions, electrical and magnetic loadings. The results obtained using proposed d-q circuits are compared with those obtained from FEM analysis. Steady state and dynamic performance of FPFRM and CSPFRM is evaluated with proposed d-q circuits.
