ABSTRACT:
A gas-cooled rotor assembly for use with a turbogenerator type device, wherein a coil side is positioned within a winding slot formed in the rotor core, such that a pair of cooling channels extend between opposite sides of the coil side and adjacent wall portions of the winding slot. Positioning devices of insulating material are positioned adjacent to radially inner-most and outer-most end portions of the coil side, with the positioning devices electrically insulating the coil side from confronting surface portions of the slot walls, while at the same time transmitting tangential forces therebetween.
