Abstract:
Method for retrofitting an electric machine to reduce temperature rise therein. The method allows for removing at least a portion of an originally assembled coil support on a spider structure of the machine. The originally assembled coil support is configured to allow only axial flow to cooling air from a plurality of cooling vents in the armature of the machine. The method further allows for mounting a new coil support on the spider structure. The new coil support is configured to provide axial and radial routing to cooling air passing from the plurality of cooling vents. The air routed radially by the new coil support passes proximate the coil end turns and enables a reduction of temperature rise in the machine.
