| Abstract: | Inner-rotor direct-coupled structure is adopted in wind generator design.Pre-design of the generator is carried out with equivalent magnet circuit method.The generator characteristics in the states of no load,rated load and short circuit are analyzed with finite element method.The result shows that the cogging torque is small and working points are reasonable,and irreversible demagnetization will not happen in short circuit state. |
