Generators having rotors that provide alternate magnetic circuits

A generator comprising:

• stator comprising:
• a generator coil wrapped around a generator core;
• a first magnetic flux element having a first stator pole,
• wherein the first magnetic flux element is magnetically coupled to a first end of the generator core across a first gap having a first reluctance;
• a first magnetic flux donor that donates magnetic flux having a first polarity to the first magnetic flux element;
• a second magnetic flux element having a second stator pole,
• wherein the second magnetic flux element is magnetically coupled to a second end of the generator core across a second gap having a second reluctance;
• and
• a second magnetic flux donor that donates magnetic flux having a second polarity, opposite to the first polarity, to the second magnetic flux element;
• 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 the third magnetic flux element has a third gap that is at least partially disposed within the rotor coil;
• 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 generator has a fourth gap between the first stator pole and the first rotor pole when the first rotor pole is substantially aligned with the first stator pole, and
• wherein the first reluctance is greater than a reluctance of the fourth gap when the first rotor pole is substantially aligned with the first stator pole.
