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.

Proper alignment of the pump shaft with the driver can reduce vibration and significantly improve reliability.

Although a number of AC motor designs are used, the induction motor is, by far, the most common and will be the topic of this column.

The frame sizes (physical dimensions) of AC motors have changed substantially through the years. Originally, they were considerably larger than those in use today.

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.

Due to the expense and labor required, most facilities need to maximize the life of their motors.
