Abstract

The present invention relates to a motor stator. The motor stator includes a plurality of stacked annular stator laminates defining a stator core having a plurality of stator teeth on an inner diameter thereof, at least some of the plurality of stator laminates including a plurality of coolant openings therethrough. The plurality of coolant openings of adjacent stator laminates communicate with one another in order to define cooling channels inside the stator core. At least some of the plurality of stator laminates include the plurality of coolant openings including a plurality of generally circumferentially extending slots.

Description

technical field [0001] The present disclosure relates to motor stator back iron cooling through internal passages. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Electric motors are commonly used in vehicle propulsion systems and other industrial applications. Existing electric motors include poor cooling characteristics of the windings and stator core. Overheating of the stator can reduce the efficiency of the electric motor and can reduce the performance of the motor. Contents of the invention [0004] This section provides a general overview of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features. [0005] To effectively cool a motor stator, the present disclosure provides a motor stator comprising a plurality of stacked annular stator laminations defining a stator core having on its inner diameter a A plurality of stat...
