How to measure the motor housing and prevent the motor from overheating

The motor shell, as the name suggests, is the shell of the motor, which generally plays a protective role. Many problems of the motor can be found through the measurement of the motor housing. In many cases, the motor will overheat due to excessive load or running for too long. At this time, we can judge by measuring the motor shell and repair it in time to prevent damage to the motor. The equipment for accurately measuring the temperature of the motor shell and rolling bearing includes simple expansion thermometers (alcohol thermometers are used instead of mercury thermometers), semiconductor material point thermometers or infrared thermometers, etc. Some digital clamp ammeters also have semiconductors. The role of material point thermometer. For motors with temperature measurement components (sensors) embedded in the interior beforehand, temperature monitoring should be carried out based on an external dedicated instrument panel. The dust accumulated on the outer surface of the motor shell will affect the motor's heat dissipation. The dust accumulated inside the motor shell (especially the winding) will not only affect the heat dissipation, but more importantly, it is likely to cause erosion and damage to the insulation material. Insulating layer performance, produce winding, two-color or ground penetration. Some smoke and dust enter the rolling bearing, reducing the lubricating effect and destroying the rolling bearing too early. Therefore, dust should be removed anytime and anywhere. The dust inside the open type or removable protective cover (net) can be cleaned up by air compression or vacuum cleaner. For the closed type (waterproof grade of IP44 and above), it should be disassembled on time to carry out complete Clean up. When cleaning with liquids, prevent the use of corrosive liquids.
