ABSTRACT:
An alternator, or the like including a stator assembly and a rotor assembly within the stator assembly, wherein the stator assembly includes a pair of axially spaced core sections with a stationary field coil located therebetween. The field coil is formed of convolutions extending circumferentially about the axis of the device. The rotor assembly has a homopolar core with a pair of axially spaced pole sections in locations corresponding to the respective stator core sections. A central yoke portion extends between the two pole sections and is axially aligned within the field coil. A plurality of permanent magnets are mounted circumferentially on each of the pole sections at symmetrically spaced locations between pole sectors of the respective section.
