Abstract
A stator for an electrical rotating machine includes a laminated core having coil bars and a winding head board resting on an end side of the laminated core and having a main body including a first dielectric material. Conductor tracks are connected to the coil bars and integrated into the winding head board. The winding head board has a region with a second dielectric material and/or a region with a third dielectric material, with the second dielectric material having a higher thermal conductivity than the first dielectric material. The region with the second dielectric material is arranged between a conductor track and the laminated core such that heat is transmittable between conductor track and laminated core via the second dielectric material. The third dielectric material has a higher dielectric strength than the first dielectric material, with the region with the third dielectric material arranged between at least two conductor tracks.
