Abstract (en)
[origin: WO2019068958A1] A hammer device (100) comprises a frame (101), an actuator member (103) linearly movable with respect to the frame, and a linear electric machine for linearly moving the actuator member. The frame comprises attachment members (102) for attaching to a working machine so that the frame is nondestructively detachable from the working machine. The linear electric machine comprises a mover (104) for linearly moving the actuator member and a stator (105) connected to the frame and comprising windings (106) for generating a magnetic force directed to the mover in response to electric current supplied to the windings.
