Abstract
A medical or dental, fluid-driven handle with a control or regulation circuit for the limiting, control or regulation to a maximum or predetermined rotational speed and a corresponding process 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 drive fluid, and a control or regulation circuit designed to limit, control or regulate the rotational speed of the rotary part. An electrodynamic converter is driven by the rotary part for generating electrical energy and at least one actuator element is configured to act on the drive fluid. The actuator element is electrically connected to the electrodynamic converter such that it is supplied with electrical energy generated by the electrodynamic converter.
