Abstract
A device for cooling a motor can improve motor cooling performance with multiple cooling channels formed in a stator core of the motor, allowing a coolant to flow in both directions therethrough. The device is capable of maximizing motor cooling performance in such a manner that two or more multiple cooling channels are formed in a stator core with a separate coolant inlet and outlet. The coolant moves in a straight line in different directions along each cooling channel to cool the stator core, and thus the temperature gradient of the coolant is minimized to cool the entire area of the motor evenly.
