  ZQDR310B traction motor is designed according to ZQDR310B DC traction motor technology protocol singed with CRRC  Sifang Co.,ltd. ZD126B4 DC traction motor is improved based on the previous ZQDR310A motor by changing some external interface dimensions of the motor but they have the same internal structure, in particular the same electric parameter.

Technical Feature

1. Meter-gauge locomotive (metric thread)

2. rolling axle-suspended

3. Rolled steel sheet welding frame

Technical Advantage

1. The largest power traction motor for narrow-gauge diesel locomotive in China at present

2. Simple structure, easier maintenance and low costs. Its rolling axle-hung bearing structure enables its wide application to multiple narrow-gauge locomotives.

3. It adopts steel plate pressing welding structure for frame to increase integration and enhance reliability.
