Abstract
Wind power plays an important role in the transition to new energy sources. This paper introduces a bidirectional flux-modulated radial permanent magnet (PM) generator, incorporating a mechanical flux-weakening design. The focus is on achieving mechanical flux-weakening effects through the principles of flux modulation, while employing working harmonics to ascertain the appropriate winding pole pair number and sequence. This design facilitates the regulation of the induced back electromotive force (EMF) and enables a broad operational speed range for the variable speed constant amplitude voltage (VSCAV) mode of the wind power generator. Furthermore, the strategic selection of specific working harmonics permits the generator to operate with a singular set of windings. The topology is presented, and the operational principles are thoroughly analyzed. Ultimately, the structure is subjected to testing through algorithm optimization and finite element method (FEM).
