Abstract:

this paper build up the brushless doubly fed machine (BDFM) finite element model of the coupled electromagnetic-thermal field, the electromagnetic joule heat calculated in electromagnetic environment will be loaded as the heat source to calculate in thermal field, the calculated results in thermal field will be the initial conditions to calculate the electromagnetic field, get the thermal field distribution when the motor is stable through cycle calculation at last. Calculation results show the effectiveness of this method.
