Temperature rise is a very important performance indicator of motor products, which has different degrees of impact on motor efficiency and use environment. Therefore, both motor manufacturers and motor users hope to have an acceptable temperature rise level.
 
The articles on motor temperature rise published earlier have aroused heated discussions among motor enthusiasts, and enthusiastic netizens have also put forward their own views and opinions. Combining this information, we have sorted out some content on improving motor temperature rise to share with you.
 
First, the insulation treatment of motor windings. It can be achieved by selecting insulating materials, such as selecting high-efficiency and low-thermal resistance insulating materials, which can reduce heat conduction and reduce motor temperature rise. Especially in the insulation treatment process of motors, scientific and reasonable insulation processes should be used to ensure the effectiveness of winding insulation and curing, and to minimize the air gap in the winding. For the selection of insulation treatment process parameters, different equipment, different products, and different materials will lead to differences in each process. Motor manufacturers should formulate and improve their own insulation processes and implement them through detailed data and verification.
Second, about ventilation and heat dissipation. Different motor structures use different ventilation and heat dissipation structures. However, once the structure of the motor is determined, the production and processing technology and quality control become very important for the compliance and satisfaction of the motor design. Any deviation from the design requirements may cause the motor temperature rise level to deteriorate, such as the insulation process, the matching relationship of parts, and the correctness of the selection of parts. Reasonable and scientific radiator selection and correct application can quickly dissipate heat and avoid motor overheating.
 
Third, the choice of cooling structure is very important. According to the power size of the motor and the particularity of the application environment, the standard design can be deviated from, and the heat dissipation structure of the motor can be completely improved. For example, the use of efficient coolant or air cooling system can quickly absorb heat and discharge it. According to the working environment and load characteristics, choose a suitable motor structure, such as winding structure or air cooling structure, which can improve the heat dissipation capacity of the motor. Improvements in this area are mainly reflected in large-size motors.
 
Fourth, for the control of power density, in many applications, especially those directly related to the size of the equipment, some customers will ask motor manufacturers to design capacity-enhanced motors, that is, to increase the power of the motor without changing the size of the motor. This will inevitably lead to higher power density and a high possibility of motor temperature rise. Therefore, the power density should be adjusted appropriately according to the actual needs of the motor to avoid excessive temperature rise.
 
Fifth, monitoring and improvement of the application process. For customers with conditions, a temperature monitoring system can be established according to the actual situation to monitor the temperature changes of the motor in real time, take timely measures to reduce the temperature rise, and ensure the long-term stable operation of the motor.
