Summary:The present disclosure relates to a hammer device comprising a hammer body, a hammer piston and an electrically operated piston drive arrangement. The piston drive arrangement comprises a stator fixedly positioned within the hammer body and at least in part encompassing a translator configured to act upon the hammer piston. The stator comprises a plurality of peripheral windings embedded in an interior surface of the stator and is configured to induce a reciprocating linear movement in the translator. The translator comprises an elongated stem surrounded by a peripheral, outwardly extending toothing integrally formed in the elongated stem along a longitudinal extension of the translator. The translator is made of a material of relative magnetic permeability >10 at a magnetic flux density of 0.2 Tesla.
