ABSTRACT:
A cooling vane for a rotating electric machine and method for attachment. In one embodiment the cooling vane is a corrugated ribbon of thermally conductive material having a plurality of projection points positioned along one edge of the corrugated ribbon. In another embodiment the vane is periodically twisted to bring a portion of the vane parallel with the plate to which the vane is to be welded. In one embodiment the cooling vane is welded to a stator plate of the machine by positioning the cooling vane perpendicularly adjacent the grounded stator plate and applying a high current source to the cooling vane in the region of the projection point. The high current flow through the projection point welds the cooling vane to the stator plate. A plurality of these cooling vanes are welded to the stator plate radially around the surface of the plate to provide a large surface area and to turbulate the fluid flow for the dissipation of heat which is generated within the machine during operation.
