ABSTRACT:
The invention relates to an electric motor whose rear stator winding ends are embedded in a casting of electrically insulating plastic which is hard at the operating temperature of the motor, which is mounted with a stable metal flanged plate coaxial to the motor axis and fixed to a metallic outer casing member, wherein the flanged plate for the rear winding ends is perforated and is embedded in the casting up to its flange outer edge connected with the casing member at the axial height of the winding ends, surrounding the latter with an insulating clearance, the flanged plate serving too as a heat transfer means.
A particular application of the invention is to built-in fans.
