A braking system (5) for an electric motor (1) comprises a disc-shaped driver (6), which drives a brake disc (10) by means of the motor (1). The brake disc (10) in turn drives an assembly, such as the cutting assembly of a rotor lawnmower. Between the driver (6) and the brake disc (10) there is some play, thanks to which ramp surfaces (19), which are pressed together by a helical spring (20), can move the brake disc (10) away from the motor (1) out of engagement with a number of brake blocks (24). |
