Brief Introduction
Product models: ZTP - 31, ZTP - 32
Electric motors for railways are designed for auxiliary applications in railway transportation, diesel locomotives, and electric rolling stock. They are primarily used to drive compressors, ventilation fans, hydraulic pumps, fuel pumps, and other auxiliary machinery, as well as serve as auxiliary generators and tachogenerators.
These motors comply with the following specialized technical specifications:
0XD.515.010 General Technical Requirements for DC Auxiliary Motors in Railway Locomotives and Rolling Stock
0XD.515.025 Technical Requirements for ZTP-82A Locomotive Air Compressor Motor
0XD.515.030 General Technical Requirements for Railway Locomotive Resistance Brake Ventilation Fan Motors
0XD.515.035 Technical Requirements for ZTP-180 Locomotive Air Compressor Motor
0XD.515.036 General Technical Requirements for Railway Locomotive and Rolling Stock Air Compressor DC Motors
0XD.515.040 Technical Requirements for ZTP-62K-TH Locomotive Air Compressor Motor
0XD.515.041 Technical Requirements for ZTP-63H Locomotive Resistance Brake Ventilation Fan Motor
0XD.515.044 Technical Requirements for ZTP-63H2 Locomotive Resistance Brake Ventilation Fan Motor
The motors shall operate according to their nameplate data under the following conditions
a) Altitude not exceeding 500 mm ;
b) Maximum ambient temperature: 40°C (in shaded areas) / 45°C (inside the vehicle body); minimum ambient temperature: -40°C ;
c) Relative humidity: Monthly average maximum humidity of the most humid month is 90% (with a monthly average minimum temperature of 25°C in that month);
d) Exposure to rain, snow, wind, and sand during locomotive operation;
e) Subject to normal operational shocks and vibrations of locomotives.
f) If the motor needs to operate under conditions exceeding those specified above, it can be negotiated with the manufacturer.
Structural type
The basic installation type of the motor
1. Horizontal, frame with feet (IMB3)
2. According to the needs of users, it can also be made into other installation types, single-shaft extension or double-shaft extension motors, and single-shaft extension motors can be equipped with tachogenerators or other speed measuring devices at the non-transmission end.
3. The position of the motor outlet box of IMB3 and IMB35 installation type is from the transmission end, on the left side of the frame (for the positive box), and if the user needs, it can also be on the right side of the frame (for the reverse box), or above the frame. IMBl0 and IMVl0 mounted motors do not have an outlet box.
4. The basic direction of rotation of the motor is regarded as counterclockwise rotation from the transmission end.
