Abstract:
A sub-synchronous reluctance electrical motor comprising at least one rotor formed of ferromagnetic plates and having a first plurality of uniformly distributed teeth and at least one stator including a second plurality of uniformly distributed teeth on said stator, said first plurality differing in number from said second plurality, wherein said stator comprises a plurality of sectors formed of ferromagnetic plates wherein said plates forming a sector are spaced from and non-touching the plates of the other sectors, each sector comprising at least one winding, and further comprising a monitoring device for tracking the relative position of said rotor with respect to said at least one stator, said monitoring device for sequentially energizing, via a current power source, in the direction opposite to the direction of movement of said rotor, said windings in contiguous said sectors so as to sequentially maintain energized two adjacent said sectors.
