摘要：The invention relates to a rotating electric machine comprising a rotor that isexcited by permanent magnets in which the tubular, good heat conducting support bodyof the stator forms a thermal bridge to a cooling medium. In order to be able toeffectively cool the end windings of the stator windings, a thermal bridge whichcompletely occupies the space between the end windings and the support body of thestator is also allocated to each end winding. This thermal bridge is solid and is comprisedof a solid material ring which is connected to the support body of the stator in a non-positive manner, and of a cast resin body which is poured into said solid material ring. Thiscast resin body comprises a thermal conductivity of greater than 1.6 W/m DEG K and, tothis end, contains a powdery, good heat conducting filling material provided in a quantityranging from 50 to 90 wt. %, preferably an aluminum nitride coated with silicon dioxide.
