MotorThe main function is to generate driving torque. As the power source of electrical appliances or various machinery, when a high-voltage motor fails, the most significant initial feature is the abnormal temperature rise in the hand: the temperature rise suddenly increases or exceeds the normal operating temperature.Explosion-proof motor is a kind of motor that can be used in flammable and explosive plants, and it does not generate electric sparks during operation.Explosion-proof motorsMainly used in coal mines, petroleum and natural gas, petrochemical and chemical industries.In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.Frequency conversion speed motorA general term for motors driven by frequency converters.In fact, the motor designed for the frequency converter is a special frequency conversion motor. The motor can achieve different speeds and torques under the drive of the frequency converter to adapt to the changes in the demand of the load.So what is the temperature rise of the motor?

The so-called temperature rise is the difference between the temperature and the ambient temperature during the operation of the motor, which is caused by the heating problem during the operation of the motor system.The iron core of the motor in operation will produce iron loss in the alternating magnetic field, copper loss will occur after the winding is energized, and some other stray losses, etc., all of which will increase the temperature of the student's motor control.When the motor generates heat, it also dissipates heat. When the heat generation and heat dissipation are equal, a balanced development state is reached. The temperature can no longer rise significantly and stabilize at a management level in China, which is because of the thermal stability we often say now.In order to break this balance when heat generation and increase or decrease of heat dissipation, the temperature needs to continue to rise and expand the temperature difference. Our country must adopt more heat dissipation technical measures to make the motor reach a new level at another higher temperature. balance.However, the temperature difference at this time, that is, the temperature rise, has increased than before (public number: pump housekeeper), so the temperature rise is a very important factor in the design and operation of motor products, marking the severity of the heating of our country’s motors. During operation, if the temperature rise of the motor suddenly increases, it indicates that the company's motor is faulty, or the air duct is blocked or the load is too heavy.
