Sensor arrangement having an angle sensor and a rolling bearing arrangement

Abstract

The invention relates to a sensor arrangement having an angle sensor for the measurement of rotations. The angle sensor is multipolar such that measurements are possible by means of n poles. First of all the angle sensor comprises a sensor ring surrounding an axis of rotation () and a material measure which is rotatable relative to said sensor ring. A transmitting coil () and a plurality of receiving coils () are disposed on the sensor ring. Between the transmitting coil () and the receiving coils () a magnetic circuit is formed which comprises the material measure and a pot core () having two branches (). To this end the material measure forms a variable reluctance in the magnetic circuit. One of the two branches () of the pot core () is segment-like, such that said branch comprises ring segments (). In each case the receiving coils () surround one of the ring segments (). The ring segments () each form an arc of a circle having a mean radius (). According to the invention the mean radii () of the circular arcs of two adjacent ring segments () in each case have an angle (ε, ζ, η, θ) relative to one another which is simply the integral or a multiple of the nth fraction of the right angle. The invention further relates to a rolling bearing arrangement ().
