Abstract: Rechargeable battery for supplying a power tool with electrical energy. The rechargeable battery includes a locking apparatus for releasably connecting the rechargeable battery to the power tool, wherein the locking apparatus includes at least one first and second lever element that are connected together in an articulated manner, such that the locking apparatus is reversibly movable from a locking position into a releasing position, wherein, in the locking position, the rechargeable battery is firmly connected to the power tool and, in the releasing position, the rechargeable battery is removable from the power tool.

Abstract: A non-output-side end shield (100) for a brushless electric motor (500) is provided, including a centrally arranged bearing seat (110) for accommodating a non-output-side rotor bearing (510) for a rotor shaft (560) of the brushless electric motor (500), the non-output-side end shield (100) including a sensor receptacle (150), which is used as a carrier for a sensor circuit board (550) for detecting the rotational position of the rotor shaft (560), the non-output-side end shield (100) and the sensor receptacle (150) being formed together as a one-part component.

Abstract: A hand-held power tool, in particular a hammer drill or a combination hammer, is disclosed. The hand-held power tool includes a tool housing which has a receiving recess designed to replaceably receive a storage battery or a power supply unit. The hand-held power tool has an electric drive motor with a cooling fan. The tool housing has a first vent portion which is located in the receiving recess and through which a volume flow generated by the cooling fan can be guided.

Abstract: A method to regulate the electric motor of a handheld power tool, the method encompassing the following steps: prescribing a target speed for the electric motor, varying the prescribed target speed—each time after a certain period of time has lapsed—by a value within a certain variation range in order to supply a varied target speed, and regulating an actual speed of the electric motor to the supplied varied target speed.

Abstract: A grinding tool, in particular a concrete grinding tool, comprising a drive spindle (1) driven by a motor in the working rotational direction (A) having a tool receptacle (7) at its free end. The tool receptacle (7) is provided with a flange (2) non-rotationally disposed on the drive spindle (1) and a nut (3) that can be threaded onto the free end (6) for clamping the tool (5) against the flange (2). The tool receptacle (7) further comprises an anti-rotation device (4) that prevents a rotation of the tool (5) relative to the drive spindle (1) in the working direction of rotation (A) of the drive spindle (1).

Abstract: A belt conveyor includes a strut adapted to be connected to at least two parallel arranged drive elements. At least one belt is positioned on the cross strut between the two drive elements. A detachable connecting mechanism detachably connects the belt to the cross strut.
