A handheld power tool includes an output shaft, a drive unit, a securing ring, and a securing element. The output shaft is configured to be releasably connected to an insert tool of the handheld power tool. The drive unit is configured to transmit a movement to the output shaft. The securing element is configured to secure the securing ring. The securing element has a recess which is provided to surround the securing ring in the radial direction in at least one operating state.

Handheld power tool

A portable power tool, in particular an angle grinder, includes a housing that accommodates a drive and an electronic device with an interface configured to electrically connect the electronic device. The power tool further includes a housing inner part that is configured as a drive housing and supports the electronic device. The interface has at least one first electrical interface contact region and at least one second interface contact region spaced apart from the first interface contact region. At least one insulating element spaced apart from the interface contact regions is arranged between the housing inner part and the electronic device. The insulating element is configured to avoid an electrical short-circuiting connection between the first interface contact region and the second interface contact region.

Portable power tool

A hand-held power tool includes a housing, a filter support, a plurality of securing element, and an actuating unit. The filter support has receiving openings, at least one first fixing element, and at least one second fixing element. The receiving openings are configured to receive filter elements configured to seal the hand-held power tool against a penetration of dust into the housing of the hand-held power tool. First and second fixing elements are fixable to corresponding securing elements arranged on the hand-held power tool, and are configured to releasably fix the filter support to the housing. The actuation unit is actuatable to release the filter support from the hand-held power tool.

Hand-held power tool comprising a filter support

A hand-held power tool, in particular an angle grinder, includes a drive unit, a machine housing, and a user interface unit. The machine housing surrounds the drive unit. The drive unit is configured to transmit a motion to an output unit. The user interface unit is configured to operate the hand-held power tool, and is either (i) positioned on an inner element of the hand-held power tool, in particular a flat outer surface of the inner element, or (ii) connected to the inner element, in particular the flat outer surface of the inner element.

Hand-held power tool

A filter support for a handheld power tool includes at least one filter support element, a first fastening element, and a second fastening element. The filter support element includes at least one receiving opening configured to receive a filter element. The filter elements of the filter support are preferably associated with air inlet openings of the handheld power tool and are configured to filter dust particles and/or material particles from a cooling air flow. The filter support can be fastened to a handheld power tool via the first and second fastening elements. The first and the second fastening elements of the filter support can be connected to each other. Advantageously, no fastening elements are provided on the handheld power tool.

Filter support for a handheld power tool

A hand-held power tool, in particular an angle grinder, includes a tool receiver, a tool housing, and a drive motor arranged in the tool housing. The drive motor is configured to be switched on and off via an electric On/Off switch for driving the tool receiver. The hand-held power tool also includes an actuating device configured to actuate the On/Off switch. The actuating device has a pivotably mounted actuating element and a pivotably mounted pawl that is configured to be coupled to the actuating element. The pawl is further configured, in a free-running state, to move pivotably relative to the actuating element and, in an actuation state, to exert upon the actuating element an actuating force that actuates the actuating device.

A hand-held power tool includes an electric motor, a housing, and a housing cover. The housing includes an opening located in the vicinity of carbon brushes of the electric motor, such that the carbon brushes can be removed through the opening in the housing. The housing cover includes air inlets through which cooling air can flow into the interior of the housing. The opening in the housing is detachably closed by the housing cover.

Housing cover for a hand-held power tool

A hand-held power tool includes a housing, a motor, a cooling unit, and a plurality of electronics. The housing includes a first housing part and an air intake opening. The motor is assigned to a drive train of the hand-held power tool. The cooling unit is configured to cool the motor. The plurality of electronics is located in the housing. The first housing part includes at least one air channel that is integral with the first housing part. The air intake opening is configured to conduct a cooling air flow directly to the motor via the at least one air channel.

Hand-held power tool with a cooling unit

An electric motor construction kit for assembling a plurality of electric motors includes at least one module and a plurality of assemblies for constructing the plurality of electric motors. At least one assembly of the plurality of assemblies includes one or more modules of the at least one module. Apart from a cooling system of an electric motor of the plurality of electric motors, each module of the at least one module is constructed from carry-over parts.

Electric motor construction kit and electric motor

A power tool, particularly a hand power tool, has a motor housing and a housing cover, in which a brush cover can be removably inserted. Corresponding form-fitting elements are arranged on the motor housing and on the housing cover, said elements being connected to each other in a form-fitting manner in the assembled position. The brush cover is held on the housing cover and/or on the motor housing in a form-fitting manner.
