ZD126直流牽引電動機ZD126 D.C TRACTION MOTOR

　　ZD126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承結構，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。

　　ZD126 D.C. Traction Motor is one gype of the max power put in narrow-gaged Diesel Locomotive. Main characters: wide rage of adjusting speed with constant powoer, good commutation and good generality. The frame is provided with welded steel plate and hugging bearing structure; Armature winding cross and lie flat,;Use Kapton insulation film on armatrue; Use NOMEX insulation paperto insulate to the earth; Bind unidirectional weftless gage on the front end of the slot, bind no-magnetic coated tin wire on the back end; brush hand is reaction type, brush hand speing is spiral. Motor use good insulation materials, rotor and stator use vacuum pressure dip coating . The motor is mainly used on narrow-gaged locomotives.
