Abstract :
TO PROVIDE EXCITATION for a magnetic amplifier operating at a 400-cps signal carrier frequency, a single-phase generator of at least 10 times carrier frequency was needed. This digest describes the design and test performance of a machine rated at 240 volts, 6 amperes at unity power factor, 4,600 cps, 158 poles, 3,500 rpm.
