With more than 350,000 motors operating in the rail sector, LEROY-SOMER offers complete drive mechanism ranges designed for this business sector.
A worldwide group
With sites throughout the world and an accessible network of locally-based sales offices, LEROY-SOMER offers complete drive mechanism ranges that meet the specific requirements of this business sector.
Specific drive mechanisms for the rail sector
LEROY-SOMER has put together a special offer of onboard customised drive systems for rail applications which meet the mechanical and electrical requirements of international rail programs: mechanical constraints affecting rolling stock: vibrations, shocks, temperatures, as well as electrical constraints such as voltage peaks, THD (Total harmonic distortion) and Dv/Dt.
LEROY-SOMER has a multidisciplinary engineering team which is highly qualified in the railway business. This resource allows us to manage global projects with direct input from our Research and Development department. The increased service life of trains and compliance with standards are essential criteria for users, as expressed via the LCC (Life Cycle Cost) and MTBF (Mean Time Before Failure) parameters. LEROY-SOMER are with you right from the feasibility study through to commissioning of the equipment, including the equipment testing phases and training of personnel.
LEROY-SOMER's new drive technologies offer significant advantages: a reduction in weights and dimensions, an increase in efficiency, a reduction in current surges and optimisation of the motor-converter package, etc. These developments represent substantial advantages for future rail projects.
