Performing preventive maintenance checks on electric motors is part of facility asset management. An electric motor breakdown can cause a massive impact on the facilities that rely on them for daily operations because it would have a direct effect on the productivity as well as the profit of the company. This implies that electric motors are the lifeblood of your company’s operations and therefore the need to take critical care of them. Theoretically, the lifespan of electric motors is 20 years but thousands of them go into the trash can long before their maturity period. To help you increase the longevity of your electric motor this article outlines several tips you can use.
Always keep your electric motor clean. There are several threats to the health of your electrical motor, but no one is as a threat as the dirt. Although electric motors are well sealed to keep dirt, dust, and oil out of inner components it’s always good to regularly clean them. The motor’s external fins and fan are responsible to dissipate heat from the motor, however, if there is dust, dirt, or debris it will interfere with the fan’s ability to cool itself which could lead to the motor’s internal damage or failure. You need to recognize that for every 10 degrees increase of motor operational temperatures above the insulation class limit you cut the life of the internal insulation by half. Furthermore, debris and dust near insulations can find their way to the internal system of the electric motor.
Make sure you schedule a regular examination of the electric components. Generally, in an industrial setting, all electric components should be regularly maintained. In most cases, electric failures in this environment are a result of a loose connection, moisture, or poor connection. Therefore, making regular preventive maintenance schedules can help identify these problems before they become critical and cause major loss to your company. A thermographic inspection is among the best ways to identify electrical problems in electric motors which is normally done at peak load conditions.
Always check the belts of your electric motors. Make sure you regularly check the integrity of the electric motors because a worn-out belt can lead to failure that results in equipment damage, injuries, or even deaths. Therefore, regularly check electric motor belts for wear and tension. This can save you from an unexpected breakdown at your company consequently saving you from potential loss of profits.
Regular noise and vibration test is another way to maintaining electric motors in good condition. Before you take your electric motor for repair or maintenance makes sure you do noise and vibration inspection first. The presence of mechanical noises or vibration may be an indicator of a plethora of issues such as electrical or mechanical imbalance, brush shuttering, loose windings, or misalignment. Learning what and where the problem is with your electric motor before taking it out for repair helps you make reasoned decisions and where possible take necessary preventive measures to avoid severe damage to the motor. Those are some of the main ways to maintain electric motors in good conditions.
