Abstract:
1. A switched reluctance machine, comprising a rotor; and a stator encircling said rotor and comprising a plurality of radially distributed stator poles, each of said stator poles comprising a co-radial set of coils, each set of coils comprising: said plurality of radially distributed stator poles grouped into at least three sectors, each sector comprising a neighboring sub-plurality of said stator poles and a neighboring sub-plurality of said field excitation coils, said neighboring sub-plurality of said field excitation coils electrically connected in series, said received excitation current of each of said sectors independently controllable, each phase coil in a given sector assigned a different phase from each other phase coil in a said given sector; and an electronic controller configured to operate the switched reluctance machine (SRM) as a motor/generator, in one of a plurality of operating modes comprising: a switched mode, wherein current in the field excitation coils is zero, and the SRM operates as a conventional SRM.
