Indirect drive in-wheel system for HEV/EV traction
2013 World Electric Vehicle Symposium and Exhibition (EVS27), 2013 In-wheel traction allows simplicity and freedom for the design of hybrid-electric/electric vehicle (HEV/EV). However, the in-wheel motor increases the unsprung mass and hence deteriorates ride co fort and reduces the road holding capability of the car.

2014 International Power Electronics and Application Conference and Exposition, 2014
In this paper, the mathematical model of the PMSM (permanent magnet synchronous motor) traction drive system is established. After the linearization of the model, the equation of state which takes the fluctuations of the DC traction voltage as input is deduced.

A Fault-Injection Strategy for Traction Drive Control Systems
IEEE Transactions on Industrial Electronics, 2017A traction drive control system (TDCS) plays an important role in safety running of high-speed trains. This paper presents a new fault-injection strategy for safety testing and fault diagnosis verification in the TDCS. First, the fault scenarios on the signal level of each faulty component are analyzed.

Dynamic Processes in the Drive System of Electric Traction Vehicles
Vehicle System Dynamics, 1988SUMMARY The drive system of electric railway traction vehicles is basically influenced by two main exciting effects. On the one hand, the exciting effect of electric traction motors may be of considerable importance, whilst on the other hand, the vertical and pitching vibrations of the vehicle due to the always present track uneven-nesses are ...

Modern Locomotive Traction Drive Control Systems
Russian Electrical Engineering, 2019The increasingly strict requirements that are being placed on transportation safety and traction rolling stock automation makes necessary the development of microprocessor-based control systems. Currently, a significant part of the locomotive fleet uses a rheostat–contactor traction motor control system that was developed more than a century ago, and ...

Control systems for electric drives with asynchronous traction engines
Russian Electrical Engineering, 2009Features of the application of asynchronous three-phase engines with a short-circuit rotor for traction electric drives are discussed. Possible variants of control systems are analyzed at the structural-logic level. Recommendations of their implementation in traction electric drives of an electric-rolling stock and diesel locomotives are proven.

Locomotive drive harmonic pollution in AC traction systems
ISIE '93 - Budapest: IEEE International Symposium on Industrial Electronics Conference Proceedings, 2002AC railway systems operating at high voltage (20, 25 or 50 kV) and network frequency (50 or 60 Hz) are currently the best choice for new track design, thanks to their reliability and efficiency. However, AC railway systems are connected to the national power grid by single phase power transformers and consequently the three phase voltage vectors on the

Comparative Study of Different Drive Controller for a Traction System
2019 21st International Middle East Power Systems Conference (MEPCON), 2019The electrical traction locomotive often uses an induction motor due to the fact that it has many advantages; it has a simple construction robustness, high reliability, low maintenance cost besides it is the cheapest. This motor can be easily controlled by different techniques. This paper compares between four different types of control techniques that
