ABSTRACT:
A multi-channel generating system wherein each channel is provided with a permanent magnet generator (PMG) coupled directly to the output of a constant speed drive. An overrunning clutch is located between the PMG and the generator. The frequency of the signal from the PMG is proportional to the output speed of the constant speed drive. A circuit provides underspeed information if the speed, as indicated by the PMG, drops below a minimum speed represented by a reference voltage. The underspeed information controls the excitation and de-excitation of the generator exciter voltage and a line contactor switch.
