摘要： A self-regulating permanent magnet device has a first rotor segment and second rotor segment, each supporting a set of permanent magnets, wherein the position of the second rotor segment relative to the first rotor segment is modified based on the speed of the self-regulating permanent magnet device. By modifying the position of the second rotor segment relative to the first rotor segment, the alignment between their respective sets of permanent magnets, and therefore, the electromotive force (emf) generated in the stator coils is regulated. The position of the second rotor segment is defined by the connection of a torsion spring between the first rotor segment and second rotor segment and a reactionary torque device connected to the second rotor segment. The torsion spring creates a spring force that acts to maintain the alignment between the first rotor segment and the second rotor segment. The reactionary torque device provides reactionary torque that is proportional to the speed of the self-regulating permanent magnet device and opposes the spring force. As the speed of the self-regulating permanent magnet device increases, the reactionary torque causes the second rotor segment to rotate, thereby creating a misalignment between the first rotor segment and second rotor segment.
