Power Efficiency Corp. granted new patent for E-Save technology

LAS VEGAS, USA: Power Efficiency Corp., a clean tech company focused on efficiency technologies for electric motors, has been granted a patent from the US Patent and Trademark Office for a core algorithm incorporated in its revolutionary E-Save Technology platform. The patent encompasses the method, system and apparatus for controlling electric motors and optimizing their energy use.

“This is a very important patent for Power Efficiency,” said Steve Strasser, Chairman and CEO of Power Efficiency Corporation. “This patent covers the core control algorithm for reducing electricity use by an electric motor when it is lightly loaded and so is an integral part of our E-Save Technology platform. We are extremely proud of this technology because of the significant savings it creates for applications driven by Alternating Current Induction Motors, the workhorses of industrial and commercial equipment throughout the world. This is the second patent the company has been granted to date as part of its E-Save Technology platform.”

Power Efficiency Corporation’s E-Save Technology platform was developed to reduce electric motor energy consumption by matching the power supplied to the motor with its load. Most electric motors are sized for the worst case operating conditions of the equipment it is powering.

Since most equipment does not operate constantly at its peak potential load, it is common to see a motor operate at less than 40 percent of the rated load for significant periods of time. E-Save Technology allows for variation in the load profile and adjusts the amount of energy required to optimize the energy use of the motor. This typically results in energy savings of up to 35 percent in appropriate applications.

Utilizing three-phase Motor Efficiency Controllers, Power Efficiency has established itself throughout the world in the vertical transportation market, with numerous high profile installations at large airports, transit systems, entertainment complexes and even in the US Capitol Complex. The company is also working with several large end users, OEMs and distributors to increase its participation in industrial markets.
