摘要： A percussion mechanism includes a first shaft and a second shaft. One or more vanes are fastened to the first shaft. The vanes are arranged so as to be rotatable in a chamber of the second shaft. The chamber is filled with a magnetorheological fluid. A magnetic field source on the second shaft generates a magnetic field that is spatially modulated in the circumferential direction inside the chamber.

摘要： A machine tool with a tool holder which is equipped to mount a tool, such as a chiseling tool, moveably along a movement axis. A striking mechanism contains a primary drive, arranged around the movement axis, containing at least one magnetic coil. The striking mechanism has a striker and an anvil arranged within the magnetic coil on the movement axis in sequence in the impact direction. The anvil protrudes at least partially into the magnetic coil. In addition, the striking mechanism can have an air spring affecting the striker in the impact direction. A controlled power source forms an electrical circuit in which a current flows, controlled at a target value, from the power source and into at the at least one magnetic coil during an acceleration phase. A controller ends the acceleration phase when a change, typical for an impact, is detected in the current flowing in the magnetic coil or a change, typical for an impact, is detected in a control variable of a control circuit of the power source.

摘要： A handheld power tool includes a tool holder for holding a tool, an electric motor, a shaft connecting the tool holder and the electric motor, and a protective device for stopping the tool holder in an uncontrolled situation. The protective device includes a sensor for detecting the uncontrolled situation, a switchable current source and a normally closing magnetic brake. The switchable current source outputs a first current not equal to zero in response to signals of the sensor if an uncontrolled situation is not detected; the current source does not output a current or outputs a second current different from the first current if an uncontrolled situation is detected. The normally closing magnetic brake engages on the shaft and does not apply a torque to the shaft when energized by the first current. The normally closing magnetic brake applies a torque counteracting the rotational movement of the shaft when not energized or when energized by the second current.

摘要： A machine tool is disclosed. A magneto-pneumatic striking mechanism has a primary actuator arranged around an axis of movement and includes a first magnetic coil and a second magnetic coil. The striking mechanism has, on the axis of movement within the magnetic coils, a striker and a die. Furthermore, the striking mechanism has an air spring acting on the striker in a direction of impact. The air spring may be entirely or partially within the first magnetic coil. The air spring has a ventilation opening that is open to the environment if the striker is less than 10% of its stroke away from the die, and otherwise the ventilation opening is closed. An exchange of air with the environment is therefore only possible when the striker is near the die or is near the impact position.

摘要： In a control method for a hand-held power tool, a striking mechanism is driven with an electric motor, wherein an exciter piston of the pneumatic striking mechanism is driven periodically by the electric motor and a striking piston of the striking mechanism is coupled to the exciter piston via a pneumatic chamber. The method includes detecting the acceleration of a machine housing along a striking direction of the striking piston in different phases of the movement of the exciter piston; and controlling a rotational speed of an electric motor according to the detected acceleration in the different phases.

摘要： A hand-held power tool has a motor, a tool holder, and a percussion mechanism disposed between the motor and the tool holder in the drive train. The percussion mechanism includes a first shaft and a second shaft. A magnetically conductive ring gear is connected to the first shaft. An inner wall of the ring gear is eccentric to an axis of the second shaft. A magnetically conductive impeller is connected to the second shaft and is arranged to rotate within the ring gear. The impeller is spaced from the ring gear by a first air gap in a first position while being spaced from the ring gear by a second air gap in a second position, the first air gap being smaller than the second one. A magnet array is arranged coaxially to the second shaft. A magnetorheological fluid fills a cavity between the ring gear and the impeller.

摘要： A control method is provided for a hand-held power tool (1), which includes a motor (5) for rotationally driving a tool holder (2) about a working axis (12), including the following steps: detecting a rotary motion of the hand-held power tool (1) about the working axis (12); detecting a rotary or pivoting motion about a transverse axis (18) extending transversely to the working axis (12); triggering a safety function for reducing the torque output of the motor (5) when the rotary motion about the working axis (12) exceeds a limiting value, and suppressing the safety function when the rotary or pivoting motion about the transverse axis (18) is greater than a threshold value.
