Background
The motor is widely applied to mechanical equipment and production processes around us. Can be widely applied to the fields of factories, automobiles, airplanes, robots and the like. Regardless of the type of application, how to manage heat dissipation is a common problem. One typically selects a motor based on a particular operating or load requirement. Heat dissipation management is one of the type selection considerations. While the design of electric machines is constantly improving, they are always generating heat due to energy losses and low energy efficiency. In most cases, we achieve heat dissipation by conductive cooling. In this method, heat is conducted from the electric machine to the machine structure through the mounting interface. Another method of dissipating heat from an electric motor is forced air cooling, which is commonly done by using an electrically powered fan to blow air across the motor. The forced air cooling approach may reduce the amount of heat transferred to the machine structure, allowing the machine to operate at higher loads. Liquid cooling may also be used for motor heat dissipation. In the liquid cooling method, glycol or other liquid coolant is circulated inside or around the motor housing or coil to dissipate heat. Overheating of the motor can affect operating efficiency, affect lubrication and insulation, and even burn out the motor.
However, the conventional heat dissipation device for the motor has some disadvantages in the use process, such as:
1. when the traditional motor heat dissipation device uses forced air cooling heat dissipation, wind power blown into the motor through the fan is often dispersed after entering the motor, good convection cannot be formed in the motor, and the heat dissipation efficiency of the motor is low.
