Regal Rexnord’s Marathon Globetrotter three-phase general-purpose motors can be controlled by an inverter and are rated up to 200 hp. They are offered in open-drip-proof enclosures and rolled steel TEFC enclosures, as well as in a cast-iron enclosure rated for areas classified as hazardous locations. Marathon Symax permanent magnet ac (PMAC) motors can be powered and controlled only by a VFD but provide improved efficiency even at lower speeds and partial loads. Available for washdown and harsh-duty applications are Leeson Washguard SST stainless steel motors and the Leeson Washguard White Duck series, which features a chemical-resistant white epoxy finish. Both are offered in one- or three-phase configurations.
