Selection of Suspension Arrangement of Traction Motors : A Right Approach
Abstract Motor suspension arrangement is of paramount importance for the reliability of traction motors. Another vital input for the selection of traction motor for given motor suspension arrangement is its rotational speed. Non-availability of any complied information on the relationship of rotational speed of traction motors and their mounting arrangement makes the jobs of Rolling […]
Optimized Algorithms For Effective Driving Of Tap Changer Controlled Electric Locomotives In Indian Railways : A Case Study
Abstract In this work we propose a strategy for driving a tap changer controlled electric locomotive, specifically WAP4, which will result in the highest possible output performance while remaining within the tolerance limits of the voltage and current in the traction motors. Indian Railways’ electric locomotive fleet [1] is today dominated by tap changer controlled, […]
