CDJD114 is applied to locomotive exported to Thailand by CRRC Qishuyan Co.,LTD and features small size, large power, wide constant power and less maintenance compared with motors with the same performance. Able to supply relatively large traction power under the constraint of axle weight of the locomotive and enjoy low temperature rise, the motor is applied to locomotive for freight and passenger task in southern Thailand. At present the locomotive with our motor is still in operation in Thailand.

Technical Feature

1. Lighter weight

2. Variable frequency and speed regulating

3. Simple structure

4. Low temperature rise

5.  Interpolated tooth structure

Technical Advantage

1. Lighter mass compared with motor with the same torque

2. Easier to control rotating speed under variable frequency and wider speed regulating range under constant power

3. It adopts all disc steel plate welding structure with simple processing technique

4. It features obviously low temperature rise compared with other motors.

5. It adopts inner cone structure for transmission shaft to effectively enhance torsional rigidity of gear transmission within limited radial dimension of the pinion.
