An inductive planar constructed angle sensor

摘要

An inductive planar constructed angle sensor– with a stator (1, 6), one with a periodic alternating voltage, which is acted upon by excitation coil (2), as well as a plurality of receiving coils (3) comprises,– and a rotor (4), which the thickness of the inductive coupling between the excitation coil (2) and receiving coils (3) as a function of its angular position relative to the stator (1), which predetermines,– and an evaluation circuit for determining the angular position of the rotor (4) relative to the stator (1, 6) from the data contained in the receiving coils (3) induced voltage signals,– the rotor as a combination of two sections (9, 10) of existing double rotor (8) is formed from each of which a section with respect to each side of the stator (6) is arranged,characterized in thatthe circumference of the double rotor (8), which is connected with an actuating shaft, in front of the assembly with the actuation shaft a rounded polygon contour (12), which during the mounting on the peripheral contour (11) to adapt itself to the actuating shaft.
