Thermal and Manufacturing Aspects of Traction Motors Potting: A Deep Experimental Evaluation

Thermal effects and manufacturing processes of different potting strategies are studied in this paper. In the first small prototype, winding is impregnated traditionally with a standard epoxy-based material and then potted using a thermally conductive epoxy. In the motor with global potting, a single material and process is used to enhance heat transfer from the copper conductors in the winding to...
