Learn how to avoid misinterpretations.

Last year, a Pumps & Systems reader asked about matching variable frequency drives (VFDs) and motors.

Equipment and technology improvements can be sound investments.

In the food industry, stainless steel performs more productively and efficiently.

A simple mathematical model can be used to estimate vibration at the top of the motor in a vertical pump-motor structure.

Understanding resonance is essential for solving problems of increased vibration.

The biggest decision is determining which tolerances to align.

Cost-effective solutions reduce harmonics and improve system reliability, efficiency.

The benefits of these motors provide the flexibility needed for challenging pump applications.

Electric motors have had a huge impact on the pump industry.

Improved motor starters help Fabri-Kal achieve its green vision.

Introduced in June 2010, Super-E Motors with AEGIS Shaft Grounding Ring are used in commercial and industrial applications.

Named for a technique commonly used on failing pumps, "percussion maintenance" - where a technician beats on the pump's stalled motor with a hammer or rubber mallet - often indicates motor deficiencies in his diaphragm pump.

Bigger is better — or at least it used to be

Significant energy and money savings are realized when using variable speed motors controlled with drives.

This three part primer is a basic introduction to AC power for those in the pump industry who need a place to start. It will also provide several web references to access if you would like to further your understanding of this interesting and essential topic.

As a follow up on my AC Motors series, I thought it would be a good idea to provide a short overview of work, power and torque as it applies to the AC motor.
