What Are Some Reasons Behind the Failure of Motors

Question

Examlex · Accepted Answer

The Answer is Motor failures happen for many reasons.Abuse, lack of oil, bad bearings, insulation failure (end-of- normal life, oil, moisture), dirt or other foreign material (reduced ventilation), single-phasing, unbalanced voltage, and jammed V-belts are a few of the conditions that can cause a motor to
draw more than normal current.Too much current results in the generation of too much heat within the windings of the motor.For every 10 degrees Celsius above the maximum temperature rating of the motor, the expected life of the motor is reduced by 50%.This is sometimes referred to as the "halflife rule."
