The incredible development of the railways in the 20th century is linked to the electrification of the railway lines. Prior to that, railway were operated with the help of steam engines. Traction is defined as frictional forces acting between the drive wheel and the surface on which it moves. Countries worldwide are moving towards railways electrification and preferring monorail systems and metros. With advancing railways technologies and varying vehicular emission limitations imposed on transportation systems across the systems, the progress of the railway traction motor market is expected in future.
Shortage of Power
One of the main concerns in an electrified railway system is the shortage of power that can result into various power disturbances such as power distortion, harmonic distortions, and flickers. Such problems are frequent in freight trains that run in a low speed and high power mode. Use of traction motors in railway systems enables desired speed control achievement other than shock less smooth starting and higher efficiency range. Such motors are designed to ensure a constant output of the diesel engines by automatically adjusting to varying load and gradient. Hence, traction motors prevent overloading of the railway engines.
Advantage of Incorporating Traction Motors
Some of the key benefits achieved by incorporating traction motors in the railway engines include reduced starting time of the railways as compared to thermal motor railways and less vibrations of the train. In addition, such devices guarantee fewer emissions and minimized manufacturing and maintenance costs as a result of their small sizes. Furthermore, the traction motors lower down the performance loss in case of failure of the propulsion unit in powered train. Hence, such factors are expected to promote the railway traction motor market improvement in the coming years. The concernslimiting railway traction motor market progress are the increasing prices of such motors due to their design modifications resulting in lighter on-board devise. Furthermore, the emission and energy norms are causing integration of energy saving facilities with traction motors in the trains. Such system alterations have resulted in high harmonic noises intervening with the communication and signaling systems of the railway car.
AC or DC
The railway traction motor market is segmented upon the technology type and application. The conventional (direct current) DC traction motor is preferred in trains where speed alteration is not mandatory and power requirement is also low. For instance, the speed changing activity is not frequent in freight railway trains. AC (Alternating Current) traction motors are used in trains requiring rapid speed changes such as in metros. Traction motors are used in various types of railways such as light rail vehicle, metros, commuter train, very high speed electric multiple unit (EMU), Electric locomotive and diesel-electric locomotive.
Europe is expected to be the largest railway market
The railway traction motor market is expected to prosper worldwide due to the high speed range availability to the railway car drivers. The Europe is expected to be the largest railway market followed by Asia Pacific. The huge investments by the European nations in the advanced railway technologies are expected to contribute to railway traction motor market expansion in such region in the forecasted period. In Asia Pacific, China is assumed to be stable for such market enlargement due to the rising demand for high speed railways. Thus, such market is likely to grow in the years to come. The improving infrastructure of the railways in the U.S tends to result in railway traction motor market advancement in North America. In the rest of the world, Latin America is expected to lead such market development as a result of the growing demand for freight trains and urban transportation systems in Brazil. With the growing (gross domestic production) GDP of the rising economies of the Middle East, huge fund flow is expected in their railway sectors. Hence, such sector’s progress is likely to result provide significant benefits to the railway traction motor market.
