Abstract
A closed control system for controlling the operation of a multiple horsepower brushless direct current motor wherein a current feedback signal representative of the effective motor drive current is constructed from the instantaneous currents flowing in the stator windings. Protective circuitry is provided to shutdown the output power stages in the event of component failures to prevent catastrophic failure of other components in the system.
