ZZJ-800 Series Hoisting & Metallurgical DC Motor is a kind of DC motor used for metallurgy & hoisting,
available for steel rolling machine, crane, elevator and electric excavator etc.
The motors have lower moment of inertia (GD), higher overload capacity,
and quicker speed response so that it is possible to undergo frequent starting, braking,
and repeated change of direction of rotation. Moreover, the motors are reliable,
perform well in speed regulating, and can be operated suitably on thyristor continue rolled supplies.
The sturdy unitary round frame structure is highly resistant to shock impact.
All the windings are vacuum pressure impregnated with class F insulation, to form an integral construction with the laminated cores,
ensuring high dielectric stability and excellent heat dissipation.
Besides, the connection between armature winding and segment risers is employed by TIG welding (inert gas tungsten are welding),
thereby improving the electro-mechanical reliability.
