Covering all needs
We provide our customers with a wide range of solutions: asynchronous or synchronous (permanent magnet technology) motors, closed or open motors, various cooling and ventilation options, together with winterisation or tropicalisation options. Alstom’s Mitrac Drive motors are available for non-Alstom rolling stock, with guaranteed optimal integration into the bogie and traction chain. Our Mitrac Drive gearbox portfolio also includes fully, partly and unsuspended gearboxes.

Leading the way in permanent magnet motor technology
Alstom is an acknowledged forerunner in permanent magnet motor (PMM) technology, a high-performance and economical innovation already adopted by locomotives, tram-trains and light-rail vehicles, monorails and automatic metros, as well as regional and high-speed trains. The main benefits of a synchronous permanent magnet motor are its lighter weight and compactness compared to asynchronous motors. Together, with a higher power-to-weight ratio, provides vehicles with higher performances for reduced operating costs. As closed motors, PMMs also prevent external damage related to pollution, dirt and harsh weather, leading to reduced maintenance needs.
-
A broad range of architectures for asynchronous motors
Our Mitrac Drive portfolio also includes a broad range of asynchronous motor technologies, such as highly compact solutions offering an optimised interface with the gearbox, form or random wires, as well as various cooling options (self-ventilated, forced ventilated, watercooled). The range also includes Mitrac motors specially tailored for energy savings and noise reductions.
