Abstract
A hybrid alternator comprising a stator, and a rotor mounted for rotation within the stator and separated therefrom by an air gap. The rotor has a rotor core defining a plurality of magnetic poles wherein adjacent ones of the magnetic poles having alternating north and south magnetic fields. The plurality of magnetic poles comprises a plurality of permanent magnet poles and a plurality of electromagnetic poles. Each permanent magnet pole is defined by a permanent magnet. The plurality of permanent magnet poles comprises two (2) sets of diametrically positioned permanent magnet poles. Each permanent magnet is positioned within the rotor perimeter and associated with a pair of adjacent magnetic poles to form adjacent permanent magnet poles.

An electrical machine comprising:
- a generally-annular stator;
- and
- a rotor rotatably mounted within said stator and defining an axis of rotation, said rotor having an axially-extending periphery, said rotor comprising a plurality of wound-field poles disposed about at least one portion of said periphery and a plurality of permanent magnet poles all disposed about at least one circumferentially-different portion of said periphery, said wound-field poles in general axial alignment with said permanent magnet poles;
- wherein said wound-field poles are disposed in circumferentially-consecutive pairs.
