Electrical machine with winding head cooling, has winding with conductors in winding head radially separated in layer and/or separated by distance piece with at least one radial cooling channel

摘要

The electrical machine has a winding with several conductors (3) in a winding head that are radially separated from each other in a layer (4,5) and/or are separated by a distance piece (30) with at least one radial cooling channel. The conductors are in the form of rectangular braids and several layers of conductors are similarly arranged radially one above the other in the winding head space.
