ZQDR-310 |
ZQDR-310 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 GE761A19 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 GE761A14, GE761A15, GE761A19 and GE761A23.
