Abstract
A rotary piston machine is disclosed. In one aspect, the machine includes a shaft and a shaft encoder including a first structure, based on which the rotational speed and/or the rotational position of the shaft can be determined by scanning the first structure with a sensor. The shaft encoder has a rotationally asymmetrical mass distribution in order to produce an imbalance.
