ABSTRACT:
A rotor for an electrical machine has large permanent magnets located at half the pole locations, with alternating pole locations containing ferromagnetic projections which become consequent poles in the rotor. The permanent magnet poles have a high reluctance, while the ferromagnetic poles have a very low reluctance, thereby affording variable flux linkage between the rotor and a stator. Magnetic homogeneity is improved, while susceptibility to thermal degradation in the rotor is reduced substantially.
