5– 250 HP

Reliability is critical.

We’ve manufactured motors for over 125 years.

In 1879, GE founder, Thomas Edison constructed the first electric
motor ever made for a 110 to 120 Volt line at Menlo Park, NJ. This
device still exists and is operative! It is located in the Edison Historical
Collection in New Jersey.

Since then, GE has been designing, developing and perfecting DC
motor technology for industrial applications—culminating in the
MD800 Armored Mill Motor.

Applications and Standards

This low base speed, high torque motor is used in high performance,
automatic control systems that require a fast transient response.
These motors are ideal for use in steel plants, excavating equipment,
shipyard cranes, coal and ore dock cranes. They operate well in
constant potential or adjustable voltage drive systems with either
rectified power supplies or motor-generator sets.

MD800 motors meet standards established by the Association of
Iron and Steel Technology (AIST).
