Ac fan motor manufacturers tell you that as we all know, the running process of the motor is actually a process of mutual conversion of electrical energy and mechanical energy, and some losses will inevitably occur during this process. Ac fan motor manufacturers tell you that most of these losses will be converted into heat, which will increase the operating temperature of the motor windings, iron cores and other components.

The manufacturer of Ac fan motor tells you that since the insulating material used in the motor has a temperature limit, the task of cooling the motor is to dissipate the heat generated by the internal loss of the motor, so that the temperature rise of each part of the motor is maintained within the range specified by the standard. And strive to homogenize the internal temperature.
The Ac fan motor manufacturer tells you that the motor usually uses gas or liquid as the cooling medium. The common ones are air and water, which we call air cooling or water cooling. Ac fan motor manufacturers tell you that air cooling is common with fully enclosed air cooling and open air cooling; water cooling is common with water jacket cooling and heat exchanger cooling.
The manufacturer of Ac fan motor tells you that the design of the fan is based on the principle of obtaining the maximum cooling effect with the minimum loss, and mostly adopts the streamlined surface design to maximize the ventilation efficiency of the fan and reduce the ventilation noise at the same time.
