ZZJ***0 motors are a
kind of DC motors 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
continuerolled 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.
