Marathon High Voltage Motors

Marathon high voltage motors are made of high quality cast iron or fabricated steel frames. With an optimized construction and design, Marathon high voltage motors ensure strong, rigid frames and high power density. The laminations used in stator cores and rotor cores have premium surface insulation and low loss, which ensures higher efficiency. The Marathon high voltage motor’s insulation system is built with high quality insulation material. The high rigidity of its winding ends can endure the intensity of switching and reversing. F class insulation provides the motor with high heat stability and long insulation life.
