Abstract: A communication unit for an electrical machine, in particular a hand-held machine tool, includes at least one electrical actuator, a control unit configured to control the at least one electrical actuator, and a receiving unit assigned to a mobile or stationary unit. The at least one electrical actuator and the control unit together form a transmission unit. The transmission unit is configured to transmit data, and the receiving unit is configured to receive the data. The receiving unit includes at least one microphone. To transmit data, via the transmission unit, the control unit is configured to trigger the electrical actuator to generate an acoustic signal that is detectable by the at least one microphone.

Abstract: A drive base module of a modularly constructed multifunctional handheld machine is configured to connect to at least one attachment device. The drive base module includes at least one connection device including at least one drive-technological interface and/or a data-technological interface configured to connect to the at least one attachment device. The drive base module further includes at least one drive unit configured to drive the at least one attachment device in a state in which the at least one attachment device is connected to the at least one connection device. The drive base module further includes at least one rechargeable battery unit; and at least one information output unit configured to output information to an operator acoustically and/or haptically.

Abstract: A tool basic module, in particular for a stand-alone use, includes a drive unit, a main output, and a coupling device. The coupling device includes a mechanical interface and an electrical interface. The mechanical interface is configured to establish a mechanical drive connection between the main output and at least one attachment device. The electrical interface transmits at least one of a high power and a high current, and is configured to establish an electrical connection between the at least one attachment device and the main output. The electrical connection is coupled to the mechanical connection.

Abstract: A tool basic module for stand-alone use includes a drive unit, a main output, and a coupling device that has a mechanical interface for establishing a mechanical drive connection between at least one attachment device and the main output. The coupling device includes an electrical interface which transmits a low power and/or a low current, and is provided to establish an electrical connection, coupled to the mechanical drive connection, between the at least one attachment device and the main output.

Abstract: A system includes at least one first machine tool having at least one first receiving device for at least one insert tool, at least one storage device, and at least one external unit. The at least one insert tool is configured to be arranged on the at least one machine tool. The at least one storage device includes at least one second receiving device for the at least one insert tool. The at least one external unit has at least one external input interface. At least one application-specific parameter of at least one output is generated from an input, which is transmitted to the at least one machine tool, to the at least one storage device, and/or to other external units.

Abstract: A hand-held power tool includes a drive device in a housing. The drive device is intended to drive a tool accommodated in a tool-accommodating region. An adjusting motion of the hand-held power tool by the user is detected via a sensor device. A controlled variable for setting the drive device is generated in an open-loop or closed-loop control device in the hand-held power tool according to the detected adjusting motion.

Abstract: A handheld power tool has a tool holder for holding a tool, and a grip housing for holding and guiding the handheld power tool. A relative motion of the tool holder and the grip housing can be transmitted as a switching motion to a microswitch, which switches a drive unit on and off. The tool holder and the grip housing can be moved relative to one another in a direction of rotation, and the switching motion thus comprises a rotary motion of the grip housing.
