ZQDR—310直流牽引電動機ZQDR-310 D.C TRACTION MOTOR

　　ZQDR—310直流牽引電動機的主要特點是恒功調速范圍寬，換向性能優良，通用性好，是國內目前最大功率的窄軌內燃機車牽引電動機之一。機座采用鋼板壓型焊接抱軸瓦結構，電樞繞組交叉平放，電樞繞組導線采用Kapton薄膜導線，對地絕緣用NOMEX紙槽型絕緣前端采用無緯帶綁扎，后端采用無磁鍍錫鋼絲綁扎，刷握采用反應式，刷握彈簧為螺旋式壓簧，電機采用了優良的絕緣材料，定、轉子采用真空壓力浸漆工藝。該電機主要裝在米軌機車上。

　　ZQDR-310 D.C  Traction Motor is one type of the max power put in narrow-gaged Diesel Locomotive. Main characters: wide range of adjusting speed with constant power, good commutation and good generality. The frame is provided with welded steel plate and hugging bush structure; Armature winding cross and lie flat,Use Kapton insulation film on armature; Use NOMEX insulation paper to insulate to the earth; Bind unidirectional weftless tage on the front end of the slot, bind nomagnetic coated tin wire on the back end; brush hand is reaction type, brush hand spring is spiral, motor use good insulation materials, rotor and stator use vacuum pressure dip coating. The motor is mainly used on narrowgaged locomotives.
