electric motor thermal cooling ways

   Electric  Motors are widely used in mechanical equipment and production processes around us. You can find them in factories, cars, planes, robots and even DVD vending machines. No matter what kind of application, how to manage heat dissipation is a common problem.

   People usually choose electric motors according to specific work or load requirements. Heat dissipation management is one of the factors considered in model selection. Although the design of electric motors is constantly improving, they always generate heat due to energy loss and low energy efficiency. You need to consider this when you choose the right  electric motor according to your needs.

    In most cases, we achieve heat dissipation through conductive cooling. In this method, heat is transmitted from the electric motor to the machine structure through the installation interface. Automobile manufacturers usually indicate the radiator size on the parameter table. This radiator size is used to determine the continuous torque capacity of the electric  motor. The heat dissipation capacity will affect the load capacity of the electric  motor.

     Another method of electric  motor thermal cooling  is forced air cooling. It is common practice to use an electric fan to blow air through the electric  motor. The forced air cooling method can reduce the heat transmitted to the machine structure and allow the electric motor to operate under high load.

   Liquid cooling can also be used for electric  motor cooling. In the liquid cooling method, ethylene glycol or other liquid coolant circulates inside or around the electric motor housing or coil to dissipate heat. This is similar to the heat dissipation system of automobile engine.
