Abstract
The cooling of an electric motor is optimized by the housing of the motor being provided with inlet vent holes that are positioned and sized to increase a total air flow rate through the housing interior and by the interior surface of the housing being shaped to conform to the stator winding end turns of the motor to direct a flow of cooling air around a greater surface area of the winding end turns before being exhausted through outlet vent holes of the housing.
