Abstract

The invention relates to an electric winding body which has improved performance characteristics as a result of being impregnated with a thermoplastic material filled with phase change material. These performance characteristics relate to improved heat dissipation, vibration damping, fixing of the coils, and improved protection against overheating by utilizing the sensitive and latent heat storage properties when the polymer units transition from the semi-crystalline state into the amorphous state.
