ZQDR***0 motor is a four-pole, force-ventilated series wound DC
traction motor, which is designed for narrow-gauge diesel
locomotive. The motor has features of wide speed regulating range
in constant power, good commutation and universality. It is the
highest power traction motor used in narrow-gauge diesel
locomotives in China. The magnet frame is weleded with press-formed
steel plates, the armature windings are made of Kapton film
conductors and lie flat and crisscross in the slots, the ground
insulating of armature windings uses NOMEX channel shape structure,
the front end of armature is banded by fiberglass tape, the rear
end of armature is banded by non-magnetic tin-plated wire, brush
holder is reacting model, spring of brush holder is a spiral-type
pressed spring. The motor uses high quality insulation material,
VPI is applied in producing the stator and rotor. It is sure to be
more reliable and durable and can replace GE**1A*9 Traction
Motor
The motor can be used in the kinds of narrow-gauge diesel
locomotives which are exported to Nigeria by Dalian Locomotive and
Rolling Stock Works.
Now, we also can supply Traction Motors can be interchanged with
GE**1A*4, GE**1A*5, GE**1A*9 and GE**1A*3.
