Latest Motors Articles

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.

In the past year, the rate of acceleration in the cost of raw materials (including steel, iron ore, copper and aluminum) has reached unprecedented levels in the pump and rotating equipment industries.

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.

Mechanical resonance occurs when an external source amplifies the vibration level of a mass or structure at its natural frequency.

Owing partly to tradition, the shafts of electric motors are often larger than those of the equipment they drive.

A paper or an electronic work order system can be used to capture alignment data.

The Energy Independence and Security Act of 2007 (EISA), which restates and broadens the definition of General Purpose Electric Motors, goes into effect on December 19, 2010.
