Cast Iron Motors

Marathon Electric's line of cast iron BLUE MAX motors includes totally enclosed fan cooled, inverter duty motors designed for trouble-free operation at just 1/20 of base speed. High performance windings and other improvements enable these motors to operate at the slower speeds often required by inverter drives, without the need for auxiliary blowers. As a result, the BLUE MAX 20:1 constant torque motors are built in their normal NEMA frame sizes, making retrofits easy.
