Maintenance of Electric Motor
Electric motors may look like any other electrical component, but they have a massive impact on the company’s profitability and productivity. So it is critical to perform regular preventive maintenance checks on electric motors to ensure they always perform at their peak.
Here are some tips may help:
1. VISUAL INSPECTION
Take a look at its physical condition. If the electric motor operates in a rugged environment, you will see signs of corrosion and dirt buildup on individual components. Observe the motor’s windings to detect any hint of overheating, such as a burnt odor.
2. BRUSH AND COMMUTATOR INSPECTION
Any hint of excessive wear leads to commutation problems with the motor. Also keep a check on the commutator. Replace all worn out parts.
3. WINDING TEST
If the windings are overheated, the chance of serious damage is higher.
4. BEARINGS TEST
Check the bearings for noise and vibration as they indicate potential problems, like poor lubrication, dirt buildup, and wear and tear.
5. VIBRATION TESTS
Sometimes, excessive vibrations are difficult to detect manually. But, if not detected on time, vibration can reduce the life span of an electric motor, which then eventually leads to motor bearing failure or failure of windings.
 
To ensure better maintenance of electric motors, all maintenance procedures and tests should be conducted systematically in order to pinpoint potential problems and correct them before they result in undesired downtime. This approach not only improves the motor’s operation, but also increases its life span.
Different electrical materials have different maintenance requirements, so regular inspections must be scheduled per their needs. With electric motors, it’s a matter of understanding what they need and implementing those measures to enhance their productivity and the company’s profitability.
