Chemical production, chemical pumps with mechanical equipment, the use of a lot of motor, for the motor temperature is too high, temperature rise abnormal how to do, what is the temperature rise?

Temperature rise: it is an important parameter to measure and evaluate the heating degree of the motor, which is obtained under the state of heat balance under the rated load of the motor. End customers feel the quality of the motor, the usual practice is to touch the motor, to see how the shell temperature, although not accurate but also generally pulse the motor temperature rise. When the motor fails, the remarkable initial feature is the "feel" abnormal temperature rise: the "temperature rise" suddenly increases or exceeds the normal working temperature. At this time, if measures can be taken in time, at least great property losses can be avoided.

Temperature rise and temperature.
For motor manufacturers, they pay more attention to motor temperature rise, but for motor users, they pay more attention to motor temperature; for a good motor product, both temperature rise and temperature should be taken into account to ensure that the performance index and life of the motor meet the requirements. The difference between the temperature at a certain point and the reference (or reference) temperature is called a temperature rise. It can also be called the difference between the temperature at a certain point and the reference temperature. The difference between the temperature of a part of the motor and the surrounding medium is called the temperature rise of the part of the motor; the temperature rise is a relative value.

Motor temperature rise.
The temperature rise is the difference between the working temperature of the motor and the ambient temperature, which is caused by the heating during the operation of the motor. The iron core of the motor in operation will produce iron loss when it is in the alternating magnetic field, copper loss will occur after the winding is electrified, and other stray losses will occur, which will increase the temperature of the motor. When the motor is heating, it will also dissipate heat. When the heat is equal to the heat dissipation, it will reach equilibrium, and the temperature will no longer rise and stabilize at a level, which is what we often call thermal stability. When the heat increases or the heat dissipation decreases, the balance will be broken, the temperature will continue to rise, and the temperature difference will be enlarged, so we must take additional heat dissipation measures to make the motor reach a new balance at another higher temperature. But at this time, the temperature difference, that is, the temperature rise is larger than before, so the temperature rise.
It is an important index in the design and operation of the motor, which indicates the heating degree of the motor. in operation, if the temperature rise of the motor increases suddenly, it indicates that the motor is faulty, or the air duct is blocked or the load is too heavy.
