Another effective strategy is upgrading to more energy-efficient motors . Many motors currently in operation rely on IE1 or IE2 technology , where the higher IE ratings established by the International Electrotechnical Commission ( IEC ) indicate greater efficiency . However , modern motors can achieve IE5 levels of efficiency , offering 40 % lower energy losses compared to IE3 motors , resulting in reduced energy consumption and lower CO emissions . And progress in efficiency is continuing . ABB has also unveiled a motor based on synchronous reluctance ( SynRM ) technology that offers the anticipated IE6 level of hyper-efficiency .
ABB has recently launched an energy savings calculator that grants businesses easy access to data insights based on the energy performance of their motordriven systems . The online tool , which acts as a first step of a comprehensive energy efficiency audit , gives an initial estimate of the potential energy and cost savings they can achieve by upgrading pump and fan systems driven by low-voltage direct online motors . It estimates the energy savings that could be achieved by upgrading to the latest motor and drive technology for optimal energy efficiency gains .
A frequent finding from energy audits is that many motors are oversized , often due to system designers building in substantial safety margins for contingencies that
