  • Variable speed/variable voltage generator set
    Patent number: 4926108
    Abstract: A motor-generator set for producing, within a predetermined range, a constant volts/hertz output from the generator. An engine drives an AC generator, the engine having an electronic speed regulator including a first potentiometer for adjusting a speed setting for the engine. The generator has a voltage regulator including a second potentiometer for setting the output voltage of the generator. The first and second potentiometers are ganged for simultaneous adjustment whereby adjusting the potentiometers in one direction increases the speed of the engine and the output frequency and voltage of the generator while adjusting the potentiometers in the other direction decreases the speed of the engine and the output frequency and voltage of the generator.
