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 to rotor and stator magnets. Alternating between these magnetic circuits as the prime mover rotates the rotor generates electricity.

A generator comprising:
- stator comprising:
- a generator coil wrapped around a generator core;
- a first magnetic flux element having a first stator pole;
- a second magnetic flux elements having a second stator pole;
- and
- a rotor comprising:
- a third magnetic flux element having first and second rotor poles;
- a rotor coil wrapped around the third magnetic flux element, wherein an on-and-off timing of current through the rotor coil is configured to boost rotor momentum;
- a third magnetic flux donor that donates magnetic flux having the second polarity to the third magnetic flux element;
- and
- a fourth magnetic flux donor that donates magnetic flux having the first polarity to the third magnetic flux element, and
- wherein the first stator pole and the first rotor pole are magnetically coupled across a third medium having a third reluctance when the first rotor pole is substantially aligned with the first stator pole, and
- wherein the first reluctance is greater than the third reluctance when the first rotor pole is substantially aligned with the first stator pole.
