  • Bauer Gear Motor – Guide to IE4

    Motors that meet IE4 energy efficiency standards, such as BAUER’s PMSM range, are usually permanent magnet arrangements, where the permanent magnets maintain their own persistent magnetic fields and are generally made from rare earth metals. Conversely, the materials are not particularly rare, they just happen to come from the class of metals known as rare earth metals.
