Abstract

The interaction of rotor and stator is such that without making contact at a relative rotation they supply voltages or a train of pulses which corresponds to the speed of rotation. The rotor (5) and the stator (7) are combined as one unit which comprises an anti-friction bearing (1 to 4). The rotor (5) is fixed to one rolling track ring (1) and the stator (7) to the other rolling track ring (2) of the anti-friction bearing. The rotor (5) and the stator (7) are arranged in the space between and fixed to two parallel retaining rings (11, 12) which are connected to the rolling track rings of the anti-friction bearing.
