ABSTRACT:
A control system for controlling the excitation of a DC motor or generator activates an auxiliary power source to increase the magnetic field intensity in one or more field windings of the motor or generator when the intensity falls below a desired level, especially during a low voltage mode of operation. The system includes an excitation control system which generates a feedback signal for controlling a subexciter circuit included in the auxiliary power source in response to signals generated from detection elements that monitor various operational conditions of the motor or generator.
