Abstract

A machine housing 2 encloses a hollow drilling shaft 1 and a chuck 3. A free piston 4 co-operates with a percussion piston 5 within said shaft 1. Two electric motors having rotating armatures 8, 9 respectively located within common stator 7 or respective stators drive shaft 1 and percussion piston 5 respectively. The armature 8 drives bevel gears 13, 6 via a hollow shaft 12 which @. The armature 9 drives a crank gear 11 which operates percussion piston 5. The armature circuits are adjustable independently of one another, the relationship between the rotational speed of any drilling tool and the percussion frequency being freely selectable. The motors may be controlled together to provide a speed relationship. The motor armatures and their shafts alternatively lie parallel within a single stator. <IMAGE>
