Chapter 2 Induction Motor and Faults

2018-7-19  the most vulnerable parts for fault in the induction motor are bearing, stator winding, rotor bar, and shaft. Besides due to non-uniformity of the air gap between stator-inner surface and rotor-outer surface motor, faults also occur. Different studies have been performed so far to study reliability of motors, their performance,

An interruption of the rotor circuit can result in a voltage transient (e.g., “rapid restrike” or “reclosure”) failure mode. Most wound rotor motor rotor circuits use a series of fixed resistors, with contactors used to close each subsequent step.

Top 4 Causes Of Electric Motor Failure - IBT Industrial ...

2021-4-14  For proper motor operation, phase voltage imbalance should be less than one percent. IBT’s Electrical Group Director, Joe Purcell, recommends avoiding motor use if the voltage imbalance is greater than 5 percent. Single phasing, a voltage unbalance that causes a three-phase motor to only run on two phases, can also result in motor failure ...

Common Causes for Electric Motor Failure - Motor

2021-4-22  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.
