Electromagnetic brake
From Wikipedia, the free encyclopedia
On trams and trains, an electromagnetic brake is a track brake where the braking element is pressed by magnetic force to the rail, i.e. the braking is by friction, not the magnetic effect directly.
This is different from an Eddy current brake where there is no mechanical contact between the braking element on the moving vehicle and the rail.
This is also different from other forms of a track brake, where the braking element is pressed on the rail by mechanical means.
