Controller reduces motor electricity costs

Three-phase and single-phase Motor Efficiency Controllers for industrial and home appliance use reduce electricity costs for motors that run at a constant speed. The company estimates E-Save Technology has the potential to save $1.7 billion in electricity a year in industrial applications in the U.S. alone.

electricity used by electric motors that are at times lightly loaded and operate at a constant speed. The company estimates E-Save Technology has the potential to save $1.7 billion in electricity a year in industrial applications in the U.S. alone.
The company has developed two products based on E-Save Technology. One is a three-phase Motor Efficiency Controller (MEC), which improves the efficiency of motors in escalators, elevators, granulators, saws, stamping presses, conveyors, crushers, and other industrial applications. The second is a single-phase MEC targeted at small motors in clothes washers and dryers, refrigerators, and other appliances and light commercial equipment. Both MECs can be adopted by OEMs and other large volume sales channels.
Steven Strasser, Power Efficiency chairman and CEO, says that an announcement will be forthcoming soon regarding the signing of Power Efficiency’s first contract with a major OEM for its digital MEC to be installed on new equipment as well as retrofits.
Strasser says the agreement was signed after extensive lab and field testing and product development work undertaken by both parties. Additional OEM agreements are also underway, according to the company.
