What are the reasons for high motor temperature?
The reasons for motor overheating include mechanical equipment failures and excessive resistance caused by worn motor bearings； High ambient temperature ； There are several aspects related to the poor temperature characteristics of the motor itself.
There are many reasons for high motor temperatures: high load on the motor, poor heat dissipation in the motor (such as the absence of fans on the motor), and so on.
We have one here as well; the temperature of its motor bearings is extremely high. It’s a new multi-motor unit, and we applied butter to it, but the temperature still didn’t drop. It’s really annoying.
If it’s just a bearing issue, can we try replacing the bearing? Also, using too much oil can cause the bearings to overheat. The oil level in the bearing chamber must not exceed 2/3 of the space.
High motor temperature: High ambient temperature； The electrical load is high ； There is insufficient lubricating grease in the bearing (it can be added if there is a filling port) ； Motors with low rotation speed (an axial flow fan can be added at the rear cover to improve heat dissipation) ； The fan blades do not match ； Wait. . . .
Reply to 1# yxlyp: Nowadays, many motors do not achieve their nominal power levels in practice; as a result, they operate under overload conditions, especially new motors.

It is likely due to the following reasons: problems with the bearings (replace or lubricate them), high load (understand the production conditions to determine the cause), and high ambient temperature (check the condition of the exhaust fans or install temporary fans on site)~~~~
