Technical Specifications
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).
Key Features
•
Heavy-duty, double tapered shaft is removable and replaceable
•
Single width cylindrical roller bearings for high intermittent
and impact thrust capacity
•
TIG welding of the armature coil leads to the commutator
makes the motor highly resistant to overloads
GE Benefits
•
Fast dynamic response and smooth speed control due to
optimal system inertia
•
Advanced Tape-Reinforced Encapsulated Construction
(TREC
®
) coil technology is highly resistant to contamination,
vibration, impact and wear
•
Specifically designed to accelerate, decelerate, or reverse
under conditions of severe duty-cycle operation
•
Optimal Class H insulation protection
