Electric motors are a vital component to enhance the profitability and productivity of a company. Today, with technological advancements, electric motors have become more competent and dependable; however, sometimes they fail to perform.

Just like any other electrical equipment, regular maintenance is essential to ensure that the electric motor is producing the proper amount of power for the job and is doing so without excessive strain. Therefore, to keep your electric motor in its best condition, it is necessary to provide it with appropriate maintenance and a favorable operating environment. Proper maintenance also helps in detecting and identifying potential problems that the motor may face, so that you can timely address those issues and reduce your unexpected repair expenses.

Below, we have mentioned 5 basic tips to maintain an electric motor for all of your equipment.

1. Ensure Proper Lubrication

As we know, lubrication is essential for increasing the life of a bearing. Most people either use oil or grease for lubrication purpose, but they don’t know how much amount of lubricant is to be used. It is crucial to use the correct quantity and type of lubricant at the right interval because both over and under greasing have a negative impact on the bearing.

2. Timely Visual Inspections

Sometimes, you can avoid a major problem by a simple quick visual inspection. Just by inspecting the physical condition of your electric motor you can find out some important details. This includes checking for signs of corrosion, dirt buildup on components, overheating, or any peculiar burnt odor.

3. Check the Bearings

Maintaining electrical equipment requires planning and inspecting. If the bearings are too hot or create excessive noise and vibration, it is an indication of poor lubrication, dirt buildup, and wear and tear. Therefore, make sure you know all the maintenance requirements of the different kinds of bearings being used in the plant.

4. Perform Vibration Tests

Most of the times, failure of motor bearing or windings is linked to excessive vibrations which are difficult to detect manually. Often a defective sleeve or ball bearings, or improper balance results in such vibration. Therefore, make sure to perform some tests, like field vibration analysis which assess the exact frequency vibration and helps in identifying the exact cause of vibrations.

5. Use Infrared Thermography

The infrared thermography is the latest method of inspection which is a non-invasive form of checkup. This method uses an infrared camera to observe temperature and thermal patterns when the equipment functions at full load. The thermal images provide a temperature profile of the electric motor. Thus, the infrared camera can detect any unstable voltage in the form of a thermal image and any problem, such as insufficient air flow, insulation malfunction, or defect in the stator can be found out.

In addition to the above-mentioned maintenance tips, make sure to follow instructions provided by the manufacturer. The quality of electric motor and lubricants also play a vital role in determining the performance of your motor. A planned and periodic inspection is essential to prevent your electric motor from potential breakdowns. Moreover, if your workers are attentive, they can easily identify problems with machinery, such as unusual burning smell, excess heat in bearings, or strange sounds or vibrations.
