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 have 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. The hybrid alternator also includes a temperature monitoring voltage regulator that provides protection against overheating damage while permitting the alternator to significantly exceed its rated output for short periods of time or in colder ambient temperatures.
