Every day, trains, trams and subways help people around the world get to work, meet friends or go on holiday. Passengers on these modes of transport expect comfortable travel experiences and safe transit. ebm-papst is making an important contribution to this with its durable, robust and reliable components. All products meet the requirements unique to rail transport, such as continued functionality in the event of shocks and vibrations, noise reduction and IP protection.
There isn’t much space on the front window of a train to fit a windscreen wiper. At the same time, it also has to generate high torques. These requirements are fulfilled with an extremely durable and compact angular geared motor. It is configured to between 1.2 and 2.4 million movement cycles.
Converters change the high voltage in the overhead lines so that it can be used for the various loads in the train. As this conversion generates heat, the converter needs to be cooled. This task is generally performed by centrifugal fans.
A variety of door drives allow train doors to glide open and closed smoothly and quickly, as every second counts in rail transport. Depending on the requirement, these drives use planetary gears, combinations of planetary gears with angular gears or special gears.
To ensure that the driver and passengers arrive at their destinations in comfort, the driver’s cabin and passenger carriages are air conditioned. The air is conveyed by axial and centrifugal fans. This is e.g. the case in the new ICE4 that is operated by Deutsche Bahn.
