In normal operation of double - fed induction wind generator,stator winding inter - turn short circuit is one of the most common faults. Using the finite element method（ FEM）analysis of doubly - fed induction generator （DFIG）and with the aid of Maxwell 2D module in finite element analysis software ANSOFT,the paper establishes the simulation model for the DFIG. Through the analysis and simulation on the eddy current loss in the running process of the motor,the method to minimize the loss is obtained. The internal magnetic fields under normal operation and different malfunction degrees are simulated. The failure conditions are analyzed as well,which shows that severe breakdowns can directly affect the electromagnetic field and magnetic flux of the fault phase or fault phas
