This paper has designed and produced an ac/dc permanent magnet synchronous generator which used in ac/dc power system independent. The design of the motor and the basic properties of the motor is discussed in this paper. In order to reduce the voltage regulation of the permanent magnet generator, installation of a soft magnetic material in the generator permanent magnetic pole tail, by increasing the motor load quadrature axis reactance drop improves motor voltage regulation. A prototype is made and test analysis, the generator voltage regulation rate of small, high efficiency, and the simulation result is consistent with the basic design to achieve the requirements.
