A NOVEL DOUBLE-WINDING PERMANENT MAGNET FLUX MODULATED MACHINE FOR STAND-ALONE WIND POWER GENERATION

This paper proposes a novel double-winding flux modulated permanent magnet machine (FMPM) for stand-alone wind power generation. Based on the flux-modulating effect, a concentrated winding set and a distributed winding set can be artfully equipped on one stator component. This makes the proposed machine possessing much simpler structure than traditional double-winding double-stator PM machines. Comparative study shows that the proposed FMPM can offer higher torque capability and stronger flux adjustability than the existing single-winding FMPMs.
