Abstract (en)

[origin: WO2010012453A1] A percussion mechanism has a motor (1), a drive piston (7) which can be moved to and fro in a guide cylinder (8) by the motor, and a percussion piston (9). A coupling device (5, 6) is active between the drive piston (7) and the percussion piston (9), via which coupling device (5, 6) the movement of the drive piston (7) is transmitted to the percussion piston (9). The motor (1) can be configured as a reluctance motor or as a synchronous motor. The motor can be actuable in such a way that different rotational speeds of the rotor can be generated within a percussion cycle and/or from percussion cycle to percussion cycle.
