- a beating electric power tool in which along a striking axis by an electric motor, a tool is hit.
- the electric motor has a rotor shaft arranged transversely to the impact axis with a rotor laminated core and a motor pinion which drives a striking mechanism assembly with an eccentric via a striking mechanism transmission.
- the rotor core is arranged completely diametrically to the percussion gear with respect to the striking axis.
- US 1,871,446 shows an electric hammer in which the stator coils are arranged in series and form separate non-cooperating magnetic circuits. In the rotor co-operating secondary coils are provided with the respective stator coils.
- the invention teaches an electrically operated linear actuator in an electric impact tool, which is defined by the features of claim 1.
- the linear actuator in the electric percussion tool has a rotor and a stator, wherein the rotor has at least one stack of permanent-magnetic rods arranged one above the other.
- the stand is at least partially formed of a soft magnetic material and has at least one pair of teeth with opposing teeth, each pair of teeth receiving a stack between them to form a respective air gap.
- the stator has at least two magnetically conductive inner regions, which are arranged in the direction of movement of the rotor from each other at a predetermined distance and are each at least partially surrounded by a substantially hollow cylindrical coil arrangement whose central longitudinal axis is oriented approximately transversely to the direction of movement of the rotor.
- the rotor has a stack of superposed, permanent magnetic rods. Laterally next to it, the coil arrangement of the stator and the at least two magnetically conducting inner regions surrounded by the coil arrangements are arranged on one side of the rotor. In order to operate a tool of the electric impact tool, the rotor has a drive member which cooperates via a loose coupling with the tool of the electric impact tool to transmit a mechanical impulse thereto.
- the invention has recognized that in such an arrangement of the linear actuator, the two coil assemblies can be operated so that the magnetic flux through the one of the two magnetically conductive inner regions at any time substantially equal to the magnetic flux through the other magnetically conductive inner region is.
- the overall arrangement of the two coil assemblies with the associated stator assembly in conjunction with the permanent magnetic rotor bars forms a self-contained magnetic circuit.
- the magnetic flux induced by the coil assembly in the one direction can be induced in the other direction from the other coil assembly at the same time, so that the circle closes.
- the rotor may comprise two or more stacks of permanent-magnetic rods arranged at a predetermined distance from each other, and the magnetically conductive inner regions of the stator may be arranged between the stacks of the rotor.
- a further concept on which the invention is based is to "separate out" the part of the stator causing the armature flux, namely the coil region with the stator coil arrangement spatially from the part forming the force of the linear actuator, namely the tooth region of the stator.
- This can be achieved in comparison to conventional linear motors in which the stator coils are each arranged between two teeth of the stator, a significantly higher anchor flux.
- the coil has considerably less spatial restrictions due to the design according to the invention and can therefore be optimized for minimal (ohmic) losses - and thus for maximum magnetic field induction.
- stator coil arrangement whose central longitudinal axis is oriented transversely to the direction of movement of the rotor or, in other words, substantially aligned with the central longitudinal axis of two opposing teeth of a pair of teeth, is particularly magnetically efficient, since the magnetic flux induced by such a oriented coil passes through the two Ends of the coil located tooth pairs flows equally.
- a matching force is generated in two stacks of permanent magnetic rods. This avoids skewing of the rotor without any special measures.
- the hollow cylindrical coil arrangement has a substantially rectangular cross-section viewed along its central longitudinal axis M.

- partial strokes of the rotor are possible with the arrangement according to the invention.
- ünearaktors Another significant advantage of the invention ünearaktors is that virtually only the magnetically active components (the permanent magnets) contribute to the inertial mass of the rotor, while all other parts of the actuator (coils, magnetic return, etc.) are associated with the stand. Thus, a particularly high ratio of force exerted by the actuator to inert mass can be achieved.

- the magnetically conductive inner regions may have at least one of the teeth at their end facing the rotor.
- the magnetically conductive inner regions of the stator located between the two stacks have their teeth on their ends facing the stacks of the rotor.
- stator may have at least one magnetically conductive outer region lying outside the stack of the rotor and having at least one of the teeth at its end facing the stack of the rotor.
- the stand may also have two magnetically conductive outer portions lying outside the two stacks of the runner and having the teeth at their ends facing the stacks.
- the outer region of the upright is designed to be essentially comb-shaped in cross-section, at least in one section.

- the coil assembly of the stator can be adapted to be energized by an electronic control such that the drive member decelerates before striking the impact member on the tool or a tool holder in the electric impact tool movement and the impact member travels a predetermined path in a free flight phase ,
- free flight phase is understood a movement of the percussion part in the direction of movement of the rotor, in which the impact part is not or practically no longer transported by the drive member to the tool or a tool holder in the electric impact tool; rather, as a result of a previous acceleration exerted by the rotor on the striker by drive member, the striker "flies" toward the tool or tool receptacle without further drive coupling with the striker, in other words the impact member has disengaged from the propulsion member
- a mechanical decoupling of the tool or of the tool holder from the rotor of the linear actuator is achieved at the moment when the impact part hits the tool or the tool holder.This loose coupling does not cause the individual components of the
