Abstract
Cooling of the end windings on a stator of the electric motor can be made more uniform if a physically-compliant, thermally-conductive cap is placed over the end windings. In one embodiment, a liquid coolant is sprayed on the outside of the cap. The cap serves to make the temperature more uniform in the end windings. In an alternative embodiment, a cover is placed over the cap with a coolant jacket formed between the cap and the cover. A coolant, such as transmission fluid or engine coolant, can be circulated in the coolant jacket.
