Voith Magnetarder - Bus

Better braking made easy:

The Magnetarder

Using magnets to brake a truck or bus? Not some impossible dream - with the Voith Magnetarder. Your benefits: Less wear on the brakes, higher average speeds, minimum weight – and all with no maintenance.

The Magnetarder weighs just 39 kg and works without any auxiliary power. And when magnets are used for braking, almost no heat is produced: this is ideal for natural gas-powered vehicles. And for Voith the perfect addition to the retarder program for commercial vehicles from 7.5 to 16 tons.

Braking with the most powerful magnets in the world

The permanent magnets in the Magnetarder's stator are among the most powerful in the world. They are positioned with their opposite poles next to one another. During braking, they are moved by air pressure so that the lines of force pass through the rotor. Powerful eddy currents are created in the opposite direction to the rotor rotation. The result: The vehicle is decelerated via the universal joint shaft.
