Abstract
A fluid rotary machine () includes a first movement chain with a motor () including a motor shaft () rotationally coupled to a valve element (), for example a disc valve element () or a spool valve element (), and a motor control unit configured to control rotational movement of the motor shaft (). The valve element () is configured to control a fluid flow to a gear wheel () of a second movement chain. The second movement chain includes the gear wheel (), a cardan shaft () and an output shaft (), wherein the cardan shaft () is rotationally coupled to the gear wheel () and the output shaft (). In order to provide an improved fluid rotary machine, which especially allows more flexible and accurate control of rotational movements of components () of the second movement chain are rotatable relative to the motor shaft (). Further, an encoder module () includes a sensor arrangement configured to detect rotational movement of a component of the second movement chain, for example, of the cardan shaft () and/or the output shaft () is provided.
