IE4 Motor

Bauer Gear Motor has launched an Ex rated IE4 Super Premium Efficiency motor. The new S Series is the latest development to the company's PMSM (permanent magnet synchronous motor) range. An IE4 rating is the highest energy efficiency that can currently be achieved within motor technology, making the S Series the world's most efficient motor for use in explosion hazardous areas. Motors for use in explosion hazardous areas are exempt from the EU regulations on minimum energy efficiency because, clearly, explosion protection takes precedence over energy savings. This has put some industries, such as Oil and Gas and Mining, at a disadvantage when trying to improve the overall efficiency of their operations. While safety has to be prioritised in such environments, historically this exemption has meant that operators are missing out on potential energy savings of as much as 40 percent.
