Double stator switched reluctance apparatus

摘要

A switched reluctance apparatus and method of operating the same. The apparatus has an inner stator having a plurality of poles, a rotor disposed radially outward of the inner stator and having a plurality of segments serving as poles, and an outer stator disposed radially outward of the rotor and having a plurality of poles. A respective winding is disposed between every pair of adjacent poles of either stator. The apparatus operates with a plurality of separately excitable phases, a given phase being excited by energizing the windings corresponding to the given phase. Excitation of a given phase causes induction of magnetic fluxes traversing a region substantially confined to the region of the stators and rotor segments corresponding to the given phase, and causes a substantial amount of flux to enter rotor segments not in the radial direction but perpendicular to the radial direction.

1. A switched reluctance apparatus comprising:
an inner stator having a plurality of poles; a rotor disposed radially outward of the inner stator and having a plurality of segments serving as poles; and an outer stator disposed radially outward of the rotor and having a plurality of poles, wherein the rotor is configured for rotation with respect to the inner and outer stators, wherein, between every pair of adjacent poles of either stator, a respective winding is disposed, wherein the apparatus is configured to operate as a machine having a plurality of separately excitable phases, each phase corresponding to a respective diametric subset of the windings, and a given phase being excited by energizing the windings corresponding to the given phase, wherein each diametric subset of the windings for each phase further comprises a set of diametrically opposed inner stator windings, and a set of diametrically opposed outer stator windings adjacent to the set of diametrically opposed inner stator windings, and wherein exciting any given phase induces magnetic fluxes, a substantial amount of flux lines thereof being prevented from entering ones of the segments in a radial direction and a substantial amount of flux lines thereof being caused to enter ones of the segments in a direction normal to the radial direction.
