توضیحات محصول
DC Traction Motor EMD D29
The D29 traction motor features a compact structure and relatively light weight, making it ideal for narrow-gauge locomotives with limited space while maintaining high traction performance. Its design shares similarities with the D31 motor, with some interchangeable components including the armature, though differences exist in insulation, winding, and bearings.
Renowned for its reliability and maintainability, the D29 can be overhauled to extend service life through processes such as rewinding main field coils, replacing bearings, and renewing insulation materials. This motor was widely equipped on EMD export narrow-gauge locomotives including the G18 and DDM45 models, establishing itself as a classic in international railway traction systems.
