A high potential for increase the power density and the efficiency of electrical machines consists in a improved cooling. A new implementation approach is in the pouring of the electric components into a medium, which guarantees a better heat emission to the case in a combined manner with a new cooling concept by utilization of change its phase, with that maximum loads can be absorbed thermally. At a realistic experimental model on the basis of a 3 kW induction motor of assembly line production the use of the different physical effects during heat storage was examined for the suitability for an electrical machine, when this equipped with chambers with technical paraffin were. There are represented the experimental investigations at a modified induction motor and with its result the potential of this development. Measurement and computations show the better cooling of the solid one and both the liquefied material compared to air circulation. On the other hand, the effect of the fusion heat is still insufficient because of bad heat conduction qualities of PCM material for the practical application. By means of thermal FEM simulations the experiments are supported and possibilities for new materials examined.
