Summarization and analysis of the causes of heating of motor bearings

An improper lubrication system causes a Heating problem. We have discussed this problem in many previous articles. One case is the unsuitability of the design itself. For example, the bearing oil cavity is too large and cannot form a good circulation, which will cause the bearing to occur; excessive grease filling will cause the bearing system to dissipate heat Poor; the grease does not match the working conditions, resulting in thermal degradation or cold accumulation of the fat, which will cause the bearing to heat up due to poor lubrication; especially during the operation of the motor, regular maintenance and maintenance are particularly important.

Industry Information:

Can the motor efficiency be directly judged from the magnitude of the motor current?

In many similar cases, customers do not understand that the current of high-efficiency motors is more significant than that of ordinary motors, and it is difficult to convince them with professional reports. Such a situation shows a quick question: how can motor users have a more intuitive understanding of the energy-saving effects of high-efficiency motors?

Shipping:

after 25~30days, we will deliver the goods, for loose goods are better packed by the pallet to avoid destroy
