| Abstract: | A new type of doubly salient brushless DC generator is presented in which the field excitation is provided by fielding-winding instead of permanent magnet, based on the double salient permanent motor. When it is used as a generator, the power converter and the sensor of rotor position can be canceled. This kind of motor has some advamtages, such as simple structure, simple manufacture technology, very high reliability, high power density, low cost, and high speed capability. In this paper, a prototype field-winding doubly salient brushless DC Generator is designed and calculated using 2-D Finite Element Method(FEM). Its static characteristic is obtained and is compared with experimental results. |
