Abstract
A permanent magnet machine (PMM) has a kinetic portion electrically coupled to a power conversion portion. Motive power is provided to the kinetic portion by a torque applied to a motive shaft coupled to a prime mover, such as an aircraft engine or an automobile engine. Generated power is transmitted through a plurality of electrically isolated output feeder cables. When a fault is detected, a switch is opened stopping the flow of current through the feeder cable associated with the faulty circuit. The fault condition is then rendered safe while the prime mover may continue normal operation.
