Produkt-Beschreibung
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.

Operating Conditions
- Altitude not exceeding 1200 m
- Ambient air temperature between -25°C to 55°C (when above 40°C, for every 4°C increase, rated current shall be reduced by 1%)
- In the most humid month, monthly average maximum relative humidity shall not exceed 90% (with same month's average minimum temperature not higher than 25°C)
Temperature Rise Limits
When tested at 426 V, 478 A under full field excitation from cold state for one-hour temperature rise test, and during long-duration tests at rated conditions, the temperature rise limits are:
| Component | Insulation Class | Measurement Method | Temperature Rise Limit (K) |
|---|---|---|---|
| Armature Winding | H | Resistance Method | 160 |
| Main Field Winding | H | Resistance Method | 180 |
| Commutating Winding | H | Resistance Method | 180 |
| Commutator | H | Thermometer Method | 120 |
Note: When cooling air temperature at motor inlet is 40°C or below, the temperature rise limit of the armature bearing is 95°C.
