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.
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.
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.

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.
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.
Some of the key
players in the global railway traction motor market include ABB
group, Aisin Seiki Co. Ltd., Sulzer Ltd., ALSTOM, Bombardier Inc.,
Bharat Heavy Electricals Ltd.,Hyundai Rotem Company, Mitsubishi
Electric Corporation, Saini Heavy Electrical & Engineering Co
Private Ltd., VEM Sachsenwerk GmbH and Zytek Automotive Ltd. among
others.
