Features of Traction Drives: Various Features of Traction Drives are: 1. Large torque is required during start and acceleration in order to accelerate the heavy mass. 2. The motor is subjected to torque overloads during…
Traction Drive Rating and Energy Consumption: Traction Drive Rating and Energy Consumption - The speed-time curve of Fig. I0.6(a) is reproduced in Fig. 10.9. For simplification in calculations, it is approximated by a trapezoidal curve…
Braking System in Train: Braking System in Train has number of advantages over mechanical braking. It reduces wear and tear on rails and wheels, substantially increasing their life. It is smooth, fast and can be…
Driving Axle Code for Locomotives: Driving Axle Code for Locomotives - Weight of the locomotive is supported on axles which are coupled to wheels. The weight per axle is limited by the strength of the…
Duty Cycle of Traction Drives: The Duty Cycle of Traction Drives in trains is explained with the help of speed-, torque- and power-time diagrams (Fig. 10.6) which are drawn for travel between two consecutive stations…
Coefficient of Adhesion in Traction: In Coefficient of Adhesion in Traction, the task of driving equipment consists of pushing the carriage on which it is mounted and pulling coaches and wagons behind it. Wheels coupled…
Nature of Traction Load: Nature of Traction Load describes as when the train runs at a constant velocity on level track, a number of frictional forces oppose its motion. The friction at bearings, guides etc.…
Electric Traction Services: Electric Traction Services can be broadly classified as: Electric Trains. Electric buses, trams (or tramways) and trolleys. Battery driven and solar powered vehicles. Electric Trains: Electric trains run on fixed rails. They…
