Development and construction of a solid rotor using rare earth samarium cobalt magnets for a 150 KVA Variable Speed Constant Frequency StarterGenerator electrical system is described. The system consists of the solid rotor 14-pole startergenerator which in the generate mode, is driven at 12,000 to 21,000 RPM and a cycloconverter which, converts the 9-phase variable frequency power from the generator to a high quality 3-phase, 400 Hz, 150 KVA power source. In the start mode, the cycloconverter converts 3-phase, 400 Hz power to a 9-phase variable frequency, variable voltage which is used to power the startergenerator as a synchronous motor.
