It is always a difficult point to figure out the thermal conductivity of small motor′stator-slot wind-ings, through analyzing the internal structure of stator-slot, using relevant theory of heat transmission, the e-quivalent thermal model of slot windings was established, and the method of calculate the thermal conductivi-ty of slot wingdings was devised.Finally the applicability of this model and method of calculation were veri-fied through comparing the simulation and experiments.
