Abstract:
A polyphase reluctance machine comprising:a first and second magnetic circuit assemblies arranged for relatively movement; said first magnetic assembly having a plurality of first salient poles said second magnetic assembly having a plurality of second salient poles; wherein widths of said first and second salient poles being substantially equal; and, only said plurality of first salient poles carrying windings, each of said first salient poles of said first assembly is subdivided into plural teeth; the windings for each of said first salient poles being mounted on either each of said teeth or on alternate teeth thereof, and all said windings of said teeth of each of said first salient poles being connected together to be one phase winding such that, when excited, a phase winding of each pole forms electromagnetic poles of same polarity, each wound tooth being arranged, when in use, generating left and right circular flux loops such that a rotational direction of flux loop linkings to portions of on of a right loop and a left flux loop of respective adjacent wound teeth to be the same, and said flux loop linkings joining together as a series of circular flux loops, and an arrangement of said first and said second magnetic assemblies such that, when said machine being in used, at a position of a pole corner of said second salient poles of said second magnetic assembly is in alignment with said first salient poles of said first magnetic assembly, a flux loop produces a reluctance torque to move said salient poles, wherein said pole-corner of the second assembly being sequentially increasingly aligned with the pole of the first assembly by subsequent flux loops producing reluctance torque to continue move until said first and said second salient poles of said first and second assemblies are fully aligned.
