ABSTRACT:
The present invention relates to an ergometer having an eddy current brake serving as a loading device, comprising a rotatably mounted brake wheel placed into rotation by means of a drive device and having a cylindrical ring made from an electrically conductive material. A stationary magnet system acts as a loading device and has an air gap disposed between the poles of the magnet system directed toward the ring and the ring itself. Depressions in the surface of the brake wheel run laterally to the direction of movement and are provided at one side of the air gap opposite the poles of the magnet system. The magnet system supports a measurement coil permeated by the magnetic flux which closes over the brake wheel. The fluctuations in the magnetic flux resulting from the grooves cause a voltage to be induced in the measurement coil, from which the rotational speed of the brake wheel and the effective braking torque can be calculated.
