Motors

For the first time, the United States Department of Energy (DOE) adopted energy conservation standards for small electric motors in February 2010.
The freefall in electric motor sales is a direct effect of the worldwide economic downturn, which has severely depressed industrial and commercial productions.
Due to the expense and labor required, most facilities need to maximize the life of their motors.
Due to the expense and labor required, most facilities need to maximize the life of their motors. Electrical, insulation resistance and thermal measurement are three tests that can troubleshoot motors, drives and associ­ated electrical panels and prolong their operational lifetime. Ther­mal imagers can detect potential problems and insulation resistance and electrical tests can deter­mine the cause.
Improved motor starters help Fabri-Kal achieve its green vision.
Mechanically generated sparks, electrostatic discharge and high surface temperatures are all potential ignition sources in explosive atmospheres.
Following the development of variable frequency converter drives during the 1990s, totally enclosed fan-cooled (TEFC) AC induction motors became viable options for replacing DC motors in pumping applications.
An argument in favor of IEEE-841's provision for motor bearing protection.
In June, 2007, a reader asked Electrical Apparatus magazine, "How long should motor bearings last?" The answer will astound you.
Many people feel that all pump vibrations are bad, but is this a fact or only what we think is true?
Electric motors have had a huge impact on the pump industry.
The pump industry is the largest purchaser of electric motors in the United States.

Why integrating vibration monitors with process controls provides fast response to pump faults, adds predictability and avoids unexpected shutdowns.
End users must include bearing clearance as an integral part of designing or building a pump.
A variable frequency drive’s effect on system efficiency and motor life
A number of choices are available when connecting pumps, fans and other rotating equipment to an electric motor. There are numerous mechanical and fluid coupling designs and, in some cases, a belt drive option is available.
Aligning an electric motor coupled to a large air blower required multiple measurements.
Mechanical resonance occurs when an external source amplifies the vibration level of a mass or structure at its natural frequency.
