A Review of Recent Advancements in Flux Reversal Permanent Magnet Machine (FRPMM)

The flux reversal permanent magnet machine (FRPMM) is a novel brushless double-salient permanent-magnet machine with a winding less rotor, in which phase flux polarities are reversed in the stator concentrated coils for each electrical cycle of rotor displacement. In this concept, the qualitative comparisons are made between the FRM with different varieties of brushless machines, especially a switched reluctance machine based on Flux-MMF diagram technique. This description gives the all-inclusive review of improvements of several electrical machines for adoption to renewable energy harvesting, disclose all equivalent limitations along with research favorable circumstances. Various design strategies including the magnet arrangement and winding techniques are adopted to increase the performance of FRPM. In this study results of recent contributions are discussed and analyzed.
