Power Efficiency Corporation has announced the results of tests of its new digital single-phase motor controller on two commonly used commercial electric motors. The test was conducted by Yahia Baghzouz, who is a Technical Advisor to Power Efficiency Corporation. Dr Baghzouz is a Professor of Electrical Engineering at the University of Nevada, Las Vegas and is the Co-Director of the UNLV centre for Energy Research.
The purpose of the test was to determine the energy savings achieved with Power Efficiency’s new digital single-phase motor controller prototype. Single-phase motors are typically found in residential and light commercial appliances, such as pool pumps, refrigerators, clothes dryers, heat pumps and other applications. Power Efficiency conducted this test in anticipation of efforts to enter co-development and sales arrangements with motor and appliance manufacturers.
‘We are very pleased with the results of the test conducted by Dr Bagzhouz’, said Steven Strasser, the company’s Chairman and CEO. ‘We are presently manufacturing a number of prototypes and are in discussions with several large motor and appliance manufacturers who are waiting to receive our prototype to commence their own testing and evaluation’. ‘If the evaluations by these potential customers are positive, we expect to enter co-development arrangements for including our controller as a standard component on motors in various applications’.
‘This market represents a significant revenue opportunity for the company because there are over a hundred million single-phase motors sold every year in the US’. ‘Furthermore, efficiency standards are becoming increasingly stringent for appliances and other equipment powered by single-phase motors’. ‘Our goal is to have the most cost-effective technology for appliance and motor manufacturers to meet these standards’. In a test on a 1/3 HP Emerson split-phase motor at 30% of full load, energy savings were 41% and at 50% of full load, energy savings were 24%. Testing on a 3/4 HP Baldor capacitor-start motor at 30% of full load, energy savings were 22% and at 50% of full load, energy savings were 8%.
