摘要： A hand-held power tool is disclosed. The power tool has a linear motor with a rotor, an exciter piston that is coupled mechanically to the rotor, and a bearing device with a rotor mounting to support the longitudinal movement of the rotor and an exciter piston mounting to support the exciter piston. The rotor mounting and the exciter piston mounting form a three-point mounting, which is the sole bearing for the rotor and the exciter piston.

摘要： A method of controlling a single-phase linear motor (1) for driving a striking mechanism (2) with a loose coupling (4) between a runner (5) of the linear motor (1) and a striker (6) of the striking mechanism (2) has, within a striking period in which exactly one force impact (K) of the striker (6) is carried out on a tool (8) or an anvil (7), a pull phase (Z) in which the loose coupling (4) contacts a runner-side contact surface (KL) with a one-sided constrained contact and a push phase (D) in which the loose coupling (4) contacts a striker-side contact surface (KS) with a one-sided constrained contact, and a change phase (W) provided between the pull phase (Z) and the push phase (D) in which the one-sided constrained contact changes between the two contact surfaces (KL-KS) along a contactless reciprocating gap (S) in that the runner (5) releases the one-sided constrained contact with one contact surface (KL/KS) in a regulated manner and produces the one-sided constrained contact with the other contact surface (KS/KL), the method including the step of discretely triggered at least the change phase (W) from the pull phase (Z) to the push phase (D) by the local position of the runner (5) relative to the pole period (P) of salient poles of the linear motor (1).

摘要： The inductive sensor arrangement for detecting metal objects hidden in a surrounding medium comprises a pair of field coils for generating an alternating magnetic flux by a sequential excitation with an AC-current and a pair of sense coils respectively mounted inside each associated field coil in an orientation to the axes of each of said field coils such that essentially no voltage is induced in said sensor coils in an environment free of a metallic object. If a metallic object comes into the vicinity of the inductive sensor four characteristic voltage value sets are produced by the sense coil pair which become subject of an algorithmic processing for defining a position and distinction criterion in respect to said hidden metallic object. The sensor arrangement has the advantage of a single point measurement resulting in an accurate position discrimination for a hidden metallic object like a rebar in concrete.
