CZECH BUSINESS AND TRADE<br />
safety when driving through a curve<br />
A series of technologically innovative<br />
products is gradually coming into serial<br />
production. The main innovations in<br />
this direction include a traction drive for<br />
a three-system Emil Zátopek locomotive,<br />
which places extraordinary demands on<br />
power electronics. Traction converters<br />
must adapt to the three-power systems.<br />
The most difficult part of the research<br />
concerns electromagnetic compatibility<br />
and the suppression of interference of the<br />
railway interlocking system in all countries<br />
where this vehicle is to be operated.<br />
CZ LOKO is a reliable partner for railway<br />
transporters in terms of construction, modernisation,<br />
repairs, and maintenance of diesel<br />
locomotives and special railway vehicles.<br />
SIGNALLING<br />

SUCCESS STORIES<br />
ROLLING STOCK<br />
ŠKODA TRANSPORTATION offers the<br />
solution for the production and development<br />
of low-floor trams, trolleybuses,<br />
and hybrid vehicles for ecological urban<br />
public transport. The company is<br />
also focused on the production of locomotives<br />
and trains of various concepts.<br />
Škoda Transportation focuses on the improvement<br />
and prediction of critical properties<br />
for future products, such as noise<br />
resistance, safety of traction drives, electromagnetic<br />
and thermal calculations and the<br />
subsequent optimisation of engines. Results<br />
of the research are products with pivoting<br />
bogies which have low-energy electric<br />
wheel drives, thus reducing the maintenance<br />
costs of vehicles and infrastructure.<br />
Škoda has a technology workplace for<br />
the development of synchronous motors<br />
with permanent magnets – which are a vital<br />
part of the traction drive of the ForCity<br />
Alfa tram. These motors are world leaders<br />
and enable the construction of lowbed<br />
pivoting bogies with a direct drive<br />
(without a gearbox). Each traction motor<br />
is individually controlled from its own inverter,<br />
and this allows the movements to<br />
be individually controlled for each wheel.<br />
Each traction container is designed for<br />
one traction bogie and represents the total<br />
utilisation of current high-performance<br />
electronics. By means of quick communication,<br />
it is possible to optimise passes<br />
through a curve and achieve increased<br />
Promising sectors with a high added value<br />
– tradition of <strong>Czech</strong> industrial manufacture lasting more than 200 years<br />
– the densest railway network in Europe<br />
– every 6th <strong>Czech</strong> commutes by train to go to work (CER Yearbook)<br />
– the railway is a meaningful, ecological, and economic, alternative to road transport<br />
