In this paper, the relationship between the voltage regulation of permanent magnet generator and the parameter of electric machine is analyzed. According to the conditions for low voltage regulation with inductive load, the methods of reducing the voltage regulation of permanent magnet generator by designing the proper parameter of electric machine are proposed And a low-voltage-regulation permanent magnet generator is designed. The parameters of electric machine and the voltage regulation is achieved by using the finite element method, and the accuracy and validity of the design method are proved.
