Sensor for use as torque sensor, has stator unit with coil circuit having flexible substrate running along sensor region, and evaluation circuit to evaluate signal received from one coil to determine value for rotary position of rotor units

摘要

The sensor has inductive coupling units at rotor units (114a, 114b), and a coil circuit in a stator unit (120). The coil circuit has a flexible substrate on which coils are formed as conductor, and the substrate runs along a sensor region. The unit (120) has an evaluation circuit connected in the coil circuit to evaluate a signal received from one coil to determine a value for the rotary position of the rotor units. An independent claim is also included for a method for manufacturing a sensor.
