Abstract
A medical or dental fluid-driven handle with a control or regulation circuit for the control or regulation of the rotational speed of a rotary part to a predetermined rotational speed and methods are presented. The handle comprises a rotary part that can be set in rotary motion by a drive fluid, a fluid line carrying the drive fluid to or from the rotary part or a fluid branch line that is connected to a fluid line carrying the drive fluid, and a control or regulation circuit that is designed to control or regulate the rotational speed of the rotary part. An electrodynamic converter is driven by the rotary part for generating electrical energy. An actuator element is configured to act on the drive fluid and is electrically connected to the electrodynamic converter such that the actuator element is supplied with electrical energy generated by the electrodynamic converter.
