Measurement assembly for determining a characteristic of a rotating part of a rotating system for a vehicle, vehicle, and method for operating a rotating system for a vehicle

A rotating system for a vehicle, the rotating system comprising:

• a static part;
• a rotating part rotatable relative to the static part around an axis (A);
• and
• a measurement assembly comprising:
• a first unit mounted on the rotating part of the rotating system, and comprising an analog-digital converter, a first communication interface, and a first power transmission interface, wherein the analog-digital converter and the first communication interface are communicatively coupled, and wherein the analog-digital converter and the first power transmission interface are electrically coupled;
• at least one sensor electrically coupled to the analog-digital converter;
• and
• a second unit mounted on the static part of the rotating system, comprising a second communication interface and a second power transmission interface;
• wherein the first communication interface and the second communication interface are wirelessly coupled, and wherein the first power transmission interface and the second power transmission interface are wirelessly coupled.
