Marathon® Electric Motors – Black Max® Motors

(SB526 Variable Speed Motors)

Carotron, Inc. offers AC and DC motors to fit a variety of industrial needs.  Marathon® Black Max® Motors offer a number of advantages when you need a reliable AC motor.  One feature that sets these motors apart from others is the MAX GUARD® Insulation System, which is the only insulation system that provides unlimited lead length between the motor and drive.  MAX GUARD® insulation surpasses the requirements of NEMA MG1 Part 30 and 31.  It is also an exclusive patented feature.  

Each Black Max® motor offers maximum performance and smooth integration with any AC drive, which is why they are preferred by leading drive manufacturers.  Flexibility in design is another coveted feature of Black Max® motors.  Easily add brakes and encoders without hassle.  Marathon® Electric motors have a  patented feature called the “fracket” which provides an option for mounting blowers, brakes, encoders or a combination of any three of these options.
