Shielding Cables on Case Grounds and Surge Protection
Proper shielding and grounding are critical to successful operation.Environments with a lot of electrical magnetic interference (EMI) and/or the potential of power surges, such as those that exist in...
ATLANTA, GA. (March 6, 2012)The Siemens Drive Technologies Division has combined all of its electric motors into one product family with the name Simotics, a move designed to integrate the portfolio...
Smart Motor Management
Data-driven visibility helps protect industrial processes and motors.Industrial producers typically invest millions in their infrastructure. Despite such investments, many production facilities lack...
Stainless Steel Motors
In the food industry, stainless steel performs more productively and efficiently.
Trusted gateway connections allow for system growth, efficiency and consistent maintenance at Swedish paper mill.
The construction, seals and protective monitoring contribute to the motor’s ability to operate in and under water.

Revisiting the fundamentals of data examination, time and resolution can solve equipment issues before they happen.
The Benefits of Pump Restoration and Coating
Part one of a two part seriesLast April, I received an email from Paul Maier of the Monroe County Water Authority (MCWA) in Rochester, N.Y. Paul attached a copy of his 2009 WEFTEC presentation and...
The Case of Action/Reaction
 Energy efficiency may not always mean total efficiency.The Department of Energy (DOE) has adopted new energy conservation standards for electric motors. The DOE has determined these standards...
Today’s federal requirements dictate the minimum efficiency of an electric motor, but they do not have any impact on the efficiency of a centrifugal pump. A 10-horsepower, 1,800-rpm motor must meet...
Pumps & Systems, June 2007 Named for a technique commonly used on failing pumps, "percussion maintenance" - where a technician beats on the pump's stalled motor with a hammer or rubber mallet...
Advanced motor protective relays provide superior protection for motors and pumps.For years, motor overload relays have been used to protect pumping systems. Traditionally, they monitored current to...
In 2011, I wrote a five-part series on alternating current (AC) motors and motor efficiency. This column will go into more detail about the impact of efficiency. Efficiency defines how well a motor...
Pumps & Systems, June 2007When a motor fails, users can (1) rewind, possibly for high efficiency; (2) replace the failed motor with a new motor; or (3) invest in a premium efficiency product. Here...

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....
Pumps and Systems, April 2009 The industrial motor world has a new specification available for defining the requirements of general purpose, severe duty motors in the 250- to 3,000-hp range. The...
The industrial motor world has a new specification available for defining the requirements of general purpose, severe duty motors in the 250- to 3,000-hp range. The American Petroleum Institute (API)...
The updated regulations may require machine redesign and premium efficiency motors and components.
In my July 2014 column, I demonstrated that three-phase voltage variation can significantly affect several alternating current (AC) motor characteristics. If that variation is large, it can also...
Top-of-Motor Vibration
A simple mathematical model can be used to estimate vibration at the top of the motor in a vertical pump-motor structure.
