Don't be afraid of the motor overheating

There are many problems with the motor. Including those related to lubrication and voltage spikes. In addition, overheating can occur over time. An increase in the temperature of the motor will shorten its service life. The winding insulation is degraded, and the bearing may also be degraded.

 

Reasons of motor overheating

There are many reasons for the motor overheating. There are four main reasons for overheating:

1. Overload

Standard current tests most load levels, but overvoltage may still be a problem. Reducing the current may not completely reduce overheating. It is best to understand the operating capability of the motor. Maintaining this level helps minimize overheating.

2. Start and stop

Limiting the frequency of starting and stopping the motor can reduce its heat. Pay close attention to the number of times it has been activated. Cut it down if necessary. Online motor testing is the easiest way to monitor the start and stop of the machine.

 

3. Poor power supply conditions

Power conditions usually cause overheating. The lack of power is related to the use of the VFD, although the VFD may not be the main cause of the problem.

 

4. Operating conditions

Running the motor under harsh environmental conditions can also cause overheating. Related issues include clogged pipes and high ambient temperature.

How to help the motor stay cool

One way to keep the motor cool is to reduce the excessive load that the motor handles. When considering the specifications of the task involved, match the appropriate motor to the necessary load.

Test

As part of the daily maintenance plan, testing the motor can also reduce the possibility of failure due to overheating. Don't just touch the outer surface to judge the temperature of the motor. Touch is generally not a good sensor; things that are hot for you are cool for others.

 

Maintenance plan

This is not to say don't worry about how hot the motor feels. Use appropriate test methods to find hot spots in the motor windings. Those hot spots that are easily accessible will shorten the service life of the motor.

 

Make sure your motor is properly protected. This protection includes thermostats and overload protectors. As a good maintenance plan, these devices ensure that the motor will not run at destructive temperatures.

The motor is one of the core parts of the kit. Through proper maintenance and common sense, it is easier to extend its service life.
