To help prevent such issues, it''s important to understand the common problems that cause electric motors to fail. At Industrial Motors &
Once bearing failure begins, it also creates a cascade effect that accelerates motor failure. 13 % of motor failures are caused by bearing failure, and more than 60 % of the mechanical failures in a facility are caused by bearing wear, so learning how to troubleshoot this potential problem is important.
Poor lubrication is a common cause of electric motor failure, particularly affecting the motor bearings, which rely on proper lubrication to reduce friction and support smooth operation. When bearings lack adequate lubrication, friction increases, generating excess heat that can lead to severe wear and tear over time.
As discussed, the electric motor and its drive system are always vulnerable to different types of faults, which inevitably occur . Undetected faults can lead to performance degradation, high repair expenses and even catastrophic accidents.
Low resistance is caused by the degradation of the insulation of the windings due to conditions such as overheating, corrosion, or physical damage. This leads to insufficient isolation between the conductors or motor windings, which can cause leakages and short circuits, and eventually motor failure.
Common causes include incorrect voltage supply, short circuits, or too much load on the motor. If you detect an electrical overload, immediately shut down the motor to prevent further damage. Check the power supply and load to ensure they are within the motor’s specifications.
Excessive vibration is a frequent cause of electric motor failure, often arising from issues such as imbalanced components, misalignment, or worn bearings. When a motor experiences high levels of vibration, it creates mechanical stress, which accelerates wear on internal and external motor parts.
