摘要： The invention describes a sensor device (1) and a method (11, 15) for determining a relative angular position (Δϕ) between a first shaft half (2) and a second shaft half (3) of a rotary shaft, in particular a rotary motor drive shaft, the sensor device (1) comprising:
- a first magnetic structure (4) and a second magnetic structure (5) having spatially different magnetic periodicities, wherein the first magnetic structure (4) is mounted on the first shaft half (2) and the second magnetic structure (5) is mounted on the second shaft half (3) such that respective magnetic fields generated and/or influenced by the first and second magnetic structures (4, 5) superpose,
- at least four sensors (HE1, HE2, HE3, HE4) mounted stationary with respect to a rotary movement (6) of the rotary shaft such that the superposed magnetic field generated and/or influenced by the first and second magnetic structures (4, 5) is detectable by each of the at least four stationary sensors (HE1, HE2, HE3, HE4), and
- an electronic evaluation circuit (7) configured to receive measurement values (q) corresponding to the detected superposed magnetic field from each of the at least four sensors (HE1, HE2, HE3, HE4) in order to determine the relative angular position (Δϕ) from the received measurement values (q) of the at least four sensors (HE1, HE2, HE3, HE4).
The rotary shaft may comprise a torsion section (8) elastically interconnecting the two shaft halves (2, 3) for torque transmission.

摘要： A sensor device (1202) for determining a position of a magnetic source relative to the sensor device, or for determining an orientation of a uniform magnetic field relative to the sensor device, the sensor device comprising: a substrate comprising a plurality of magnetic sensors (HI, H2, H3, H4) configured for providing a plurality of sensor signals (h1, h2, h3, h4); a signal combiner (MUX, ∑) configured for combining the sensor signals into a combined waveform; a processing circuit configured for extracting said position or orientation from the combined waveform; wherein the signal combiner is configured for generating the combined waveform by including one or more portions of the sensor signals during respective predefined time durations (Δt11 to Δt44), which time durations (Δt11 to Δt44) are determined during a calibration procedure, wherein at least two of said time durations (Δt11 to Δt44) have different values.
