U.S. Motors has been manufacturing motors since 1966 and it is a made-in-America product, manufactured by professional employees. Motors run continuously, so these machines need maintenance and for that, some points must be kept in mind.
KNOW-HOW
The maintenance of any machine is important to avoid faults and to increase the functional life of the motor. The oiling and minor adjustments are done periodically to improve efficiency. Sometimes the spare parts or components are added or removed or replaced depending on the workload. One should make sure to use the parts and components suggested by the manufacturer. While maintaining the motors, their mechanical, as well as electrical components, should be taken care of since they come in contact with external factors, so they wear out and these are crucial for the proper functioning of the motor. On the other hand, if there is a natural fault in the functioning causing interruption in the process then it is necessary to call a professional and get it repaired to have minimal effect.
PREVENTIVE MEASURES
- Visual Inspection: Examine the physical state of the equipment and take note that the contacts and relays are clean and free of rust to avoid internal issues because the equipment’s ability to function effectively could be jeopardized by the debris.
- Perform A Brush and Commutator Inspection: There are fewer chances of sudden irregularities when electric motors are examined for wear and tear; which can cause commutation issues. To restore the equipment’s functionality, you must replace the brush. And keep an eye out for any dents, grooves, or scratches in the commutator. In addition, give the motor mount, rotor, stator, and belts a careful inspection and change all worn components.
- Conduct A Motor Winding Test: You must test the motor’s windings after you have examined all the machine’s parts. You can find any irregularities or winding failures by conducting a required motor winding test if you notice any burn marks, cracks, or burning smells. The motor is disassembled as part of the examination to identify any irregularities. The likelihood of severe damage is enhanced if the windings are overheated. Important components of the test include checking the wind insulation and rewinding the motor, which both provide insight into the resistance level.
- Check The Bearings: To identify potential issues, such as inadequate lubrication, dirt accumulation, and wear and tear, listen for noise and vibration coming from the bearings. If the housing of the bearing is too hot to touch, the motor may be overheating or there may not be enough grease in the bearing. Depending on where the equipment is located, different bearings may require different maintenance. You must be knowledgeable of the various bearing types utilized in the plant and the specifications for their repair.
- Perform Vibration Tests: In some cases, it can be challenging to manually detect excessive vibrations. However, vibration can shorten an electric motor’s lifespan if it is not promptly diagnosed, which could result in winding or motor bearing failure. Most often, mechanical issues like damaged sleeves or ball bearings, excessive belt tension, or unbalanced machinery are to blame for vibration. You can test an electric motor by taking the belts off or by turning it on without any load. Even electrical issues can occasionally cause tremors. The precise cause of vibrations can be determined through a few tests, such as field vibration analysis, which is carried out using movable instruments that measure the exact frequency and amplitude of vibrations.
- Use Infrared Thermography in Predictive Maintenance: Recently, this method of inspection has become popular due to its desired outcome. With infrared thermography, an infrared camera is used to capture thermal images without interfering with the motor’s operation. These images provide a temperature profile of the electric motor by giving heat patterns at several points throughout the motor simultaneously. All mechanical systems produce a particular amount of thermal energy; therefore, they have normal thermal patterns along with a maximal temperature at which the motor can work. In case any problem exists, such as insufficient airflow, insulation failure, or degradation in the stator, the infrared camera will immediately detect the unstable voltage in the form of a thermal image, helping you find its cause and solution.
- Document Everything: Documentation is extremely important. Keep detailed records of all preventive maintenance schedules, tests performed, and their results. Maintain records of all repairs and replacements, as well. Doing so allows you to better understand the equipment, identify which issues need to be addressed, or determine which parts must be replaced or repaired. Your records also will be helpful for future audits and inspections.
Only Well-trained individuals should handle these maintenance tasks and they should be provided with all the necessary safety gear and testing devices while carrying out maintenance. They need to be aware of hazardous situations. Moreover, all electric motors should be checked and inspected on time to improve the efficiency and durability of the equipment.
