Abstract
A switched reluctance generator that can be used in an air cycle machine, where the generator uses the energy from the shaft of the air cycle machine to provide a back-up power supply to the magnetic bearings supporting the shaft. The generator includes circuitry for comparing the non-commutated excitation current with a command signal to regulate the excitation current, thereby regulating the generator output voltage.
