  Electric Traction Drives 

  http://www.railway-technical.com/drives.shtml

  The DC motor is similar to look at externally but there are differences in construction, particularly because the DC motor has a commutator and br /ushes which the AC motor does not. Nose Suspended Motor ... The following diagram shows the layout of the traditional DC motor mounted in a bogie as a "nose suspended motor". In electric trains or locomotives, the DC motor was traditionally mounted in the bogie frame supported partially by the axle which it drove and partially by the bogie frame. The motor case was provided with a "nose" which rested on a br /acket fixed to the transom of the bogie. It was called a "nose suspended motor" (see diagram above) and is still common around the world. Its main disadvantage is that part of the weight rests on the axle and is therefore unsprung. This leads to greater wear on bogie and track. Nowadays, designers try to ensure all the motor weight is sprung by ensuring it is carried entirely by the bogie frame - a frame mounted motor.

  Traction Drives MITRAC Drives (DER) MITRAC DR 500 MITRAC DR 1000 MITRAC DR 3000 More than 45 000 BOMBARDIER MITRAC DR drives with asynchronous motors are in service worldwide. This invaluable industrial ... experience is constantly reapplied at Bombardier Engineering in order to improve the drives and anticipate customer needs. Another reason why Bombardier is able to meet the high reliability and safety requirements of modern rail transport. MITRAC DR 3000 traction drive assembly Affordable combination packages thanks to professional system know-how Since the space available in the bogie is limited and since the requirements on power, noise and reliability need to be met and continually improved, cost-efficient drives can only be designed in close and long-term cooperation with the power converter and bogie engineers. The critical link is the traction drive unit, which converts electrical to mechanical traction energy. MITRAC Drive Product Families Principles for the success of MITRAC DR   [More...] [Less...]

  Railway Gazette: Synergies drive growth in traction components market 

  http://www.railwaygazette.com/news_view/article/2008/04/8361/synergies_drive_growth_in_traction_components_market.html

  Synergies drive growth in traction components market 29 Apr 2008 Harry Hondius visits ABB's 'power electronics triangle' Last year was 'a great year for ABB', according to the company's interim CEO Michel ... Demaré, who announced the ABB Group annual results in Zürich on February 14. Net income for the global business increased to a record US$3·8bn from US$1·4bn in 2006, which Demaré attributed to strong markets and operational improvements. In particular, he highlighted strong demand for power equipment, especially transformers, which drove a 37% increase in orders for the Power Products division. Following the divestment of its railway equipment business to Adtranz, ABB has focused primarily on the power equipment, process automation and robotics industries. However, it has kept a toehold in the rail sector, both in fixed equipment for electrification systems and through its Swiss-based electrical components business. Today's ABB has no ambition to supply complete electric traction pack   [More...] [Less...]
