Abstract
A rotor for a permanent magnet generator has a carrier of nonmagnetic material. One or more elements of magnetic material are carried by the carrier and provide a magnetic path in parallel with the primary magnetic path for operating flux which is coupled with the stator windings. The number of magnetic elements used determines the amount of flux diverted from the stator and thus adjusts the voltage generated in the stator winding.
