Abstract

An electric machine has a housing and has a stator inside the housing, surrounding a rotor arranged on a motor shaft so as to be fixed to the shaft. A rotary field winding, at the ends of the stator, forms a winding head. The winding heads are embedded in a thermally conductive encapsulation material, wherein the encapsulation material is in thermal contact with the housing along the outer circumference of the winding head. A segmented cooling plate is arranged on the inner circumference of the encapsulation winding head.
