Mechanical or Electrical Problem?

Click For Summary
SUMMARY

The discussion centers on the classification of a burned-out motor in a fan as either a mechanical or electrical failure. The consensus indicates that while a burned-out motor can be viewed as an electrical failure due to the shorting of windings, it may also be classified as a mechanical failure if caused by issues such as a stuck bearing. Therefore, the classification depends on the underlying cause of the motor's failure, highlighting the interconnectedness of mechanical and electrical components in such devices.

Last summer, I was taking apart a fan because it wasn't working. It turned as I expected that it was a burned out motor.

Now one of my co-workers was a little upset at me because I had called it an electrical problem or failure. He said a burned out motor is a mechanical failure.

Was he right?

I call it, mechanical problem, due to electrical failure.

It could be either. If the fan stuck for some reason, that can cause the motor to burn out. So a mechanical failure like a stuck bearing can cause the electrical failure of the windings shorting out.

Or the windings can just short out on their own (as the motor gets old and the insulation on the windings gets less effective), so that's an electrical failure.
