The Benefits of Regular Preventative Maintenance for Electric Motors in Manufacturing

The Importance of Preventative Maintenance for Electric Motors in Manufacturing Applications

Professionals across many industries understand the value of preventative maintenance and the importance of having a good working knowledge of the electric motors being used in manufacturing operations. In fact, electric motors are one of the most vital pieces of equipment in a manufacturing process, driving virtually all production equipment and processes.

For these reasons, it’s critical for businesses to understand the importance of preventing motor failure and how preventative motor maintenance can help increase productivity, reduce downtime, and save money in the long run.

Unfortunately, electric motors, regardless of the size and type, all fail eventually without proper maintenance. The effects of motor failure are felt throughout the entire manufacturing operation, disrupting equipment operation and resulting in high costs for repair and replacement.

Because of these risks, manufacturers should focus on preventative motor maintenance to extend the life of their motors and increase productivity. Preventative maintenance not only provides an early warning of potential motor issues, but also helps manufacturers identify potential upgrades and replacements to avoid future motor problems.

Preventative maintenance typically includes servicing motors regularly and replacing parts as needed. These regular maintenance procedures can help to reduce downtime, improve motor performance, and extend the life of the motor and maximize production.

Common Preventative Maintenance Tasks for Electric Motors:

• Inspecting the bearings regularly
• Replacing brushes and checking the commutator for wear (see DC Motors: Common Problems and Maintenance of Brushes)
• Inspect and clean the motor, including cleaning of the terminals, cables, and other components
• Check and adjust the drive belt, alignment of the pulley, and tension (see How Improper Belt Tension can Affect your Belt Drive System)
• Check the cooling fan and lubrication system
• Test the overall performance of the motor

To ensure the best results, it’s recommended that these tasks be repeated on a regular basis and that any repairs or replacements are made as soon as possible. Doing so will help to keep motors running smoothly with less downtime and less risk of failure. Refer to your operation’s maintenance schedule, as well as any manufacturer’s manuals to understand the frequency and tasks to complete.
