Motor cooling system with potted end turns

摘要

A thermal control system includes a stator having conductor end turns at opposite axial ends thereof, and first and second cooling systems respectively disposed at the opposite axial stator ends, each cooling system having a cover, a coolant inlet, a coolant outlet, and at least one cooling channel. Thermally conductive potting compound thermally mates the cooling systems with the end turns. A method of cooling end turns includes providing a cooling system for each axial end of the stator, each cooling system having at least one cooling channel that includes a coolant inlet and a coolant outlet, and thermally mating each cooling system to the respective end turns. A method of cooling end turns includes providing separate cooling systems in each axial end plate of an electric machine, and filling space within the end turns, and between the end turns and the cooling systems, with thermally conductive potting compound.

1. A thermal control system of an electric machine, comprising:
a stator having conductor end turns at opposite axial ends thereof; an end plate located at each axial end of the stator; separate first and second cooling systems each disposed in a respective end plate, each cooling system having a cover, a coolant inlet, a coolant outlet, and at least one cooling channel; and thermally conductive potting compound located at each axial end of the stator within the end turns and between the end turns and the respective first or second cooling system at each axial end of the stator, for thermally mating the cooling systems with the end turns.
