A method for indicating whether a hand-held power tool has reached a target is disclosed. The hand-held power tool includes a drive motor and the method includes (i) activating a target reached indication mode by way of a control unit, (ii) ascertaining a shutdown reason for the drive motor, and (iii) displaying the reaching of the target by way of a display unit as a function of the shutdown reason.

Method for indicating whether a hand-held power tool has reached a target

A hand-held power tool includes a drive unit actuatable via at least one manual switch, a control unit at least for controlling the drive unit, the control unit having a control-unit housing. The power tool further includes at least one user interface having at least one operating element, and a housing that at least partially accommodates the control unit and the user interface. The hand-held power tool also includes a positioning device, the user interface being supported on the control-unit housing by use of the positioning device.

Hand-held power tool

The disclosure relates to a method for operating a handheld power tool comprising an electric motor and the method comprising: S1 providing comparative information, comprising: S1a providing at least one model signal shape, the model signal shape being assignable to progress of work of the handheld power tool; S1b providing a threshold value of correspondence; S2 ascertaining a signal of an operating variable of the electric motor; S3 comparing the signal of the operating variable with the model signal shape and ascertaining assessment of correspondence from the comparison, the assessment of correspondence at least partially taking place on the basis of the threshold value of correspondence; S4 detecting the progress of work at least partially on the basis of the assessment of correspondence ascertained in method step S3; the providing of the comparative information at least partially taking place on the basis of a learning process.

Method for learning application shutdowns by finding characteristic signal shapes

A method for operating a hand-held power tool is disclosed, wherein the hand-held power tool includes an electric motor. The method includes carrying out a screw connection of a connecting device in a support, providing at least one signal of an operating variable of the electric motor during the screwing, evaluating the received signal of the operating variable of the electric motor, and deciding whether the screw connection has been properly carried out, the decision being at least partially based on the evaluation of the received signal of the operating variable of the electric motor. A hand-held power tool is also disclosed.

Method for operating a hand-held power tool

The disclosure relates to a method for operating a handheld power tool having an electric motor, the method comprising: Sproviding at least one model signal waveform that is associated with a work progress of the handheld power tool; Sdetermining a signal of an operating variable of the electric motor; Scomparing the signal of the operating variable with the model signal waveform and determining a conformity evaluation on the basis thereof; Sidentifying the work progress at least partially using the conformity evaluation; Sexecuting a first routine of the handheld power tool at least partially on the basis of the work progress identified in method step S. The disclosure also relates to a handheld power tool, in particular an impact driver, comprising an electric motor and a control unit, wherein the control unit is designed to carry out a method according to the disclosure.

Method for operating a handheld power tool

Method for detecting a first operating state of a handheld power tool, wherein the handheld power tool has an electric motor. In this case, the method comprises the steps of: (S) determining a signal of an operating variable of the electric motor; (S) comparing the signal of the operating variable with at least one model signal waveform typical of the state, wherein the model signal waveform typical of the state is assigned to the first operating state; (S) deciding whether the first operating state is present, wherein the decision at least partially depends on whether the model signal waveform typical of the state is identified in the signal of the operating variable in step SAdditionally disclosed is a handheld power tool, particularly an impact driver, with an electric motor and a control unit, wherein the control unit is designed to execute a method according to the disclosure.

Method for detecting a first operating state of a handheld power tool

The disclosure relates to a method for detecting work progress of a handheld power tool, the handheld power tool having an electric motor, and the method comprising the steps of: Sproviding at least one model signal form, the model signal form being assignable to the work progress of the handheld power tool; Sdetermining a signal of an operating parameter of the electric motor; Scomparing the signal of the operating parameter with the model signal form and determining a conformity evaluation from the comparison; Srecognizing the work progress to at least some extent using the conformity evaluation determined in method step S. Further disclosed is a handheld power tool, more specifically an impact driver, comprising an electric motor and a control unit, the control unit being designed to carry out a method according to the disclosure.

Method for detecting work progress of a handheld power tool

A method is for operating a hand-held power tool that includes an electric motor. The method includes determining a signal of an operating parameter of the electric motor; determining an application class at least partly on the basis of the signal of the operating parameter; and providing comparative information at least partly on the basis of the application class including (i) providing at least one model-signal form, and (ii) providing a threshold value for correspondence. The model-signal form can be assigned to an established state in the progress of the work performed by the hand-held power tool. The method further includes comparing the signal of the operating parameter with the model-signal form and determining a correspondence evaluation from the comparison. The correspondence evaluation is at least partly based on the threshold value for correspondence.

A hand-held machine tool having a tool receiver to receive an insert tool having an external profile, the tool receiver featuring an internal receiver provided at least sectionally with an internal profile, and having a tool housing assigned a tool-change magazine having at least one tool chamber for storing the insert tool, the tool chamber being alignable with the tool receiver to allow the insert tool to be transferred from the tool chamber into the internal receiver or from the internal receiver into the tool chamber, a positioning device being provided for the circumferential alignment of the external profile when transferring the insert tool from the tool chamber into the internal receiver of the tool receiver to produce a form-locking connection between the internal profile and the external profile that at least for the most part, is free of rotational play, the positioning device has at least one magnet.
