Electrical machine with stator with cooled winding rods, has distancing arrangement for winding rods consisting of axial tubular distance elements whose internal volumes form cooling medium channels

摘要

The electrical machine has a stator (10) with a sheet metal body (11) with axial grooves (12) in each of which several winding rods (13,14) are arranged one above the other and separated by distancing arrangements (19). Channels (20) are provided parallel to the rods for a cooling medium for cooling the rods. The distancing arrangement consists of axial tubular distance elements whose internal volumes form cooling medium channels.
