Torque Sensor with Inductive Rotational Angle Measurement

A torque sensor, comprising:

• a magnetized component rotatably mounted about a rotational axis;
• a fixed magnetic field sensor assembly with at least one magnetic field sensor for detecting a magnetic field generated by the magnetized component when torque is applied to the magnetized component;
• an evaluation device that determines the applied torque from the detected magnetic field;
• and
• a rotational angle sensor assembly for detecting a rotational angle of the magnetized component, wherein the rotational angle sensor assembly comprises:
• a fixed antenna element with at least one transmitting antenna assembly for transmitting an excitation signal;
• a target element that is provided synchronously with the magnetized component and rotatably relative to the fixed antenna element, wherein the target element generates a response signal to the excitation signal that depends on a current rotational angle;
• wherein the fixed antenna element comprises at least one receiving antenna assembly for receiving the response signal and generating an induction signal based on the response signal;
• and
• wherein the evaluation device is further configured to determine an instantaneous rotational angle of the target element and/or the magnetized component based on the generated induction signal.
