| Abstract |
Among the wind power generators, the axial permanent magnet generator has an advantage for increasing the power per unit volume compared to the existing radial flux generator. In this study, we calculated the cogging torque for the shapes of the permanent magnet and the stator pole in an axial permanent magnet generator, and studied the method to minimize the cogging torque. At a first step, several optimum shapes were obtained by using the response surface method. Next, the cogging torques were calculated by using finite element method and finally the optimum design was obtained to minimize the cogging torque of the generator. The analysis model was three phase 1kVA wind power generation having 24 poles and 18 slots. As a result of the optimum design, the cogging torque decreased by 7.37N?m and the EMF increased by 25.63V compared to the basic model. |
