MARATHON MOTORS

The Marathon® brand encompasses thousands of products and solutions, including single phase and three phase AC motors, NEMA and IEC motors, low and medium voltage motors, PMDC motors, and radial and axial flux motors.

Marathon offers electric motors and integrated motor/control solutions with IE4 and higher efficiencies for the toughest industries in the world. We design, engineer, and build motors from 1/4 to over 5000 horsepower with voltages from 120VAC to 13.8kV.  Our NEMA and IEC motors are used globally in both commercial and industrial applications.

Every Marathon motor is backed by more than 100 years of manufacturing experience, plus state-of-the-art engineering and production, along with comprehensive service, starting in the earliest planning stages of your motor. From variable speed motors used in commercial settings, to motors used for pumping, to high-speed extruders and “Mission Critical” motors used on ice breakers in the Arctic, a Marathon motor is the right choice.
