The flux reversal machine (FRM) topology is best suited for low speed low power application. Fractional-slot, concentrated winding, surface permanent magnet machine (FSCWS-PMSM) is also suitable for this application. Comparative study of electro-magnetic performance of FRM and FSCWS-PMSM is carried out. This study is performed for same physical dimensions, rated speed, magnetic and electric loadings...
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...
Performance comparison of IPMSMs with distributed and concentrated windings is presented in this paper. Two IPMSMs have been designed with identical rotor dimensions, air gap length, series turn number, stator outer radius, and axial length except winding configuration. Basic parameters and output characteristics, such as inductances, resistances, back emf, output torque, and efficiency, are compared...
