End users must include bearing clearance as an integral part of designing or building a pump.

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.

An argument in favor of IEEE-841's provision for motor bearing protection.

The frame sizes (physical dimensions) of AC motors have changed substantially through the years. Originally, they were considerably larger than those in use today. This increased size was the result of inefficiency and the need to dissipate heat.

This month we will quickly look at the load types that comprise a typical AC circuit.

All electric motors (motors) have a housing that contains the working components of the motor.

With highly reliable electrical systems, protective relays may be called upon to operate very infrequently.
