ABSTRACT:
An alternating current generator for supplying the electrical loads on a motor vehicle. The generator has a stator core that carries a three-phase stator or output winding. The rotor of the generator has two claw pole members that are magnetically connected by a core. A field coil is disposed about the core. The pole fingers of the claw pole members are interleaved and a plurality of permanent magnets are secured to side surfaces of the pole fingers such that there is a permanent magnet between each pair of adjacent pole fingers. The generator is arranged such that flux developed by the permanent magnets can flow through a closed magnetic path that bypasses the air gap between the rotor and stator and such that energization of the field coil with unidirectional current cause permanent magnet flux to traverse the air gap between the rotor and stator and thereby provide a useful flux for generating voltage in the stator winding.
