How Do Electric Motor Brakes Work?
Concept An electric motor brake is basically an ordinary electric motor run backward. Instead of supplying the motor with electricity to make the shaft turn, some outside force (usually from the wheels of a train or car) is applied to the shaft to make it turn, which results in the generation of electricity. Electric Motor A motor works when electricity is sequentially passed through separate coils of wire (that are designed and placed strategically around a permanent magnet attached to a central shaft), which generate magnetic fields. These magnetic fields turn on and off according to the orientation of the central magnet as it rotates to the effect of putting a constant feeling of torque on it, making it turn. Braking With no electrical input, it takes energy to turn the shaft because a force is required to spin the central magnet against the push of the wire coils. At high speeds (or revolutions per minute) this can be a substantial force, enough to slow down a car. This is why one
