Jul 21, 2010 Most of the electric motor failures occur at the start up. Most of them are caused by the over-heating of motor. There are also other factors which greatly affect the performance of electric motors such as low resistance, dirt, moisture, over-current and vibrations. Electric motors should be installed very carefully and should be looked after at regular intervals.
