An attachment (110) for a hand-held power tool (200), in particular a screwdriver or drill, wherein the attachment (110) has an attachment housing (113) and a drive element (123) on a drive side (111), which drive element can be coupled to a machine output element (221) of the hand-held power tool (200) in order to drive the attachment (110) and is firmly connected to an output element (120A) of the attachment (110) or is motion-coupled via a gear (530) in order to drive a working tool (242), wherein the attachment (110) has a fastening device (105) on the drive side (111) for detachable fastening to the hand-held power tool (200), wherein the fastening device (105) has at least one support surface (232) that is stationary with respect to the attachment housing (113) for providing support on the hand-held power tool (200) in the direction of a support axis (ST) and at least one locking body (150) adjustable between a locking position and an unlocking position and loaded into the locking position by a spring assembly (157).
A method for determining a rotor position of an electric motor (2) of a power tool (10), in particular an electric screwdriving tool, including the steps of: checking (S4) whether a first electric motor current (I1) is below a threshold value (SW), and in response to the check indicating that the first electric motor current (I1) is below the threshold value (SW), determining a rotor position of the electric motor (2) based on the first electric motor current (I1) and/or a second electric motor current.
H02P 23/14 - Estimation or adaptation of motor parameters, e.g. rotor time constant, flux, speed, current or voltage
B25F 5/00 - COMBINATION OR MULTI-PURPOSE TOOLS NOT OTHERWISE PROVIDED FOR; DETAILS OR COMPONENTS OF PORTABLE POWER-DRIVEN TOOLS NOT PARTICULARLY RELATED TO THE OPERATIONS PERFORMED AND NOT OTHERWISE PROVIDED FOR - Details or components of portable power-driven tools not particularly related to the operations performed and not otherwise provided for
The invention relates to a system comprising at least one guide rail (21, 22) which is provided for guiding a hand-held power tool (11), has an elongate shape and extends along a longitudinal axis, wherein the guide rail (21, 22) has, on mutually opposite sides, a contact face (24) for the guide rail (21, 22) to rest on a workpiece (W), and has a guide face (23), in front of which a longitudinal guide face (31), extending along the respective longitudinal axis (L1, L2), for guiding the hand-held power tool (11) protrudes parallel to the longitudinal axis (L1, L2). The system comprises a carrying device (200) having a carrying body (201, 202) and a carrying handle (120), arranged on the carrying body (201, 202), to be grasped by an operator (BE), wherein the guide rail (21, 22) has, for connecting to the carrying device (200), form-fitting contours (34) which are able to be brought into engagement with mating form-fitting contours (124) of the carrying device (200) such that the guide rail (21, 22) is able to be carried by a user (BE) using the carrying handle (120).
