DCsynchronousfor railway applications

Volume （length*width*height：mm）866x1152x687 Weight（kg）1680 Rated working voltage500V Motor insulation gradeH/H ZQDR310D is applied to locomotive exported to Brazil by CRRC Ziyang Co.,ltd. It adopts semi-suspended structure of sliding axle-suspended bearing based on ZQDR310 with frame eight-direction pressure welding structure. Compared with ZQDR310, its main technical parameters such as power, current, rotating speed and efficiency are changed slightly. The motor is mainly exported to Brazil SSD8. Technical Feature 1. Meter-gauge locomotive (American standard thread) 2. Sliding 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 sliding axle-suspended 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.
