A Revealing Look at Electric Motors and Drives

Potential Energy Savings Are Everywhere

By: | May 22, 2014 4:47 pm

Motors, Variable Frequency Drives (VFDs) and Constant Speed Motor Controllers …they are everywhere. And so are the potential energy savings!


These electric motors and drives play key roles often demanding 24/7 performance. And optimizing efficiency may provide a great opportunity for your organization to save energy while helping out your bottom line.

You may not realize it but the U.S. Department of Energy reports that the average facility can improve the efficiency of its commercial motor and drive systems by up to 18% for cost-effective practices—simply by performing basic motor maintenance functions on a weekly or monthly basis.

5 Basic Motor Maintenance Functions to Check Today

Whenever a new or rebuilt electric motor or drive is installed or adjusted in your facility, check the following:

  • Vibration
  • Noise
  • Alignment
  • Coupling system
  • Voltage

Unsuspecting things like whining can also be hints of the degrading quality of your motors and drives. It’s a good habit to check these several times per year.

The Surprising Effect of Optimizing

Another solution to consider is electric motor system optimization. This is matching the right motor with the right drive for the task. You may actually have over-sized motors or drives that could be changed out with smaller, more efficient ones.

Another example of optimizing your motor and drive system is installing Variable Frequency Drives (VFDs). Because these work on an adjustable speed scale, you use only the energy needed.

So consider small motors when appropriate, three phase motors when possible and don’t forget to regularly inspect all your motor and drive systems quarterly. The smart use of all these electric motors with the appropriate drives could improve your bottom line.
