In the electromechanical field, the temperature affects the life of the insulation system and the life of the lubrication material between relative movements, and the variation of the temperature also causes the variation of the shape of the parts, thereby affecting the performance or positioning accuracy of the electromechanical machine, and even the too high temperature causes material failure or property change. Therefore, how to efficiently dissipate heat so that the temperature of the motor machine can be maintained within an appropriate operating temperature range is an important issue.
