Abstract

A motor, comprising: an internal motor chamber, and a rotor rotatable therein. The rotor is drivable by having a pressure medium applied to it and a braking element for braking the rotor. The braking element is axially arranged directly adjacent to the rotor, wherein the braking element and the rotor are axially moveable with respect to each other and form a spring-loaded friction pair, at least between a front end face of the rotor and the braking element.
