Abstract
A generator includes a stator that has permanent magnets that complete a magnetic circuit across a series of gaps and through a generator coil. The rotor also includes permanent magnets that complete a magnetic circuit across a gap and through a rotor coil. When the rotor poles align with the stator poles, the stator and rotor magnetic circuits are broken, and new magnetic circuits are completed between the stator and rotor permanent magnets that cross the gap between the stator and rotor poles. A rotor coil can be used to boost the attraction/repulsion between the rotor and stator magnets. Alternating between these magnetic circuits as the prime mover rotates the rotor generates electricity.
