For the first time, the United States Department of Energy (DOE) adopted energy conservation standards for small electric motors in February 2010.
The SI system is the modern day version of the metric system, and the U.S. gets a lot of grief for not embracing its inherent transportability across international boundaries.
A large wastewater processing plant experienced continual problems with its influent raw wastewater pumps for several years.
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.
Bigger is better — or at least it used to be
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.
Significant energy and money savings are realized when using variable speed motors controlled with drives.
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.
Introduced in June 2010, Super-E Motors with AEGIS Shaft Grounding Ring are used in commercial and industrial applications.
It is impossible to balance line-to-line voltages perfectly in a three-phase circuit.
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.
Data-driven visibility helps protect industrial processes and motors.
