ABSTRACT:
A device for measuring the angle of rotation of a rotating member of a machine, comprising a signal transmitting rotor which includes a magnet rim consisting of magnets having alternatingly arranged south poles and north poles and being moved with respect to a stationary measuring sensor is characterized in that each magnet or each magnet zone has a thickness which varies substantially sinusoidally in circumferential direction, having its maximum in the pole center of each magnet and/or forms an air gap with the measuring sensor varying sinusoidally in circumferential direction.
