LAS VEGAS - Power Efficiency Corp., a company focused on efficiency technologies for electric motors, announced that it has been granted a third patent from the U.S. Patent and Trademark Office for another core algorithm incorporated into its E-Save Technology® platform. The patent encompasses an open loop control method for controlling electric motors and optimizing their energy use. This control method is particularly targeted at small, single-phase motors, such as those found in many types of light commercial equipment.

“This is yet another very important patent for Power Efficiency,” said Steve Strasser, chairman and CEO of Power Efficiency Corp. “This patent is a control algorithm for reducing electricity use by an electric motor when it is lightly loaded, and is particularly useful when our E-Save Technology platform is applied for single-phase motors.

“There are many millions of single-phase ac induction motors made every year for appliances, light commercial equipment, and agricultural applications. These single-phase motors are much less efficient than their larger, three-phase counterparts, but with millions of these motors sold every year, there is an enormous opportunity for energy savings.

“The company has begun developing a product that integrates its single-phase technology directly into a motor, thereby creating an electronically controlled super efficient motor. We believe this product can change single-phase motor efficiency on a grand scale because it is a very economical means of reducing energy use by the millions of inefficient single-phase motors sold every year.”

The company now has three patents and has one patent pending in the U.S. The firm has also made numerous international patent filings to protect its intellectual property in most major world markets.

Power Efficiency Corp.’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 maximum operating conditions of the equipment it is powering. Most equipment does not operate constantly at its peak potential load, and 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, said the company.
