    摘要： A magnetic device for magnetically coupling to a ferromagnetic body, comprises a housing having a central bore. A plurality of pole sectors arranged within an envelope of the central bore and forming a workpiece contact interface of the magnetic device, each of the plurality of pole sectors comprising a plurality of spaced-apart pole portions arranged at respective distances, wherein a recess of a plurality of recesses separates each pole portion of the plurality of pole portions, wherein a first sector forms a first pole of the magnetic device and a second sector forms a second pole of the magnetic device. A first permanent magnet. A second permanent being moveable relative to the first permanent magnet. And, an actuator operatively coupled to the at least one second permanent magnet to move the at least one second permanent magnet relative to the at least one first permanent magnet.

    摘要： The method for automatically picking metal elements of elongated shape, in particular bar-shaped metal profiles, provides to prearrange a gripping device (10) comprising a magnetic source (11) for picking the metal elements (2), adjustable between a condition of maximum grip and a condition of minimum grip, to adjust the gripping device (10) to a desired degree of grip, and to place it at a picking zone (3) in which the elements (2) to be picked are arranged. The gripping device (10) performs the gripping at the desired degree of grip, handles the elements (2), by holding them, to a discharge zone, and releases the handled elements (2) into the discharge zone, by adjusting the gripping degree to the minimum grip condition.

    摘要： A lifter with electro-permanent magnets is provided. It has an external bearing structure closed at the bottom by a plate, provided with a heat shield, and pole pieces secured under the respective poles and protruding from the bottom plate. Each of the electro-permanent magnets has a reversible magnet arranged on top of one of the poles, of a fixed polarization magnet formed by a plurality of blocks placed along the lateral faces of the pole and of a coil arranged around the reversible magnet to cause the reversal of the polarization of the latter by means of an electrical pulse. An airtight air gap between 1 and 4 mm high is formed between each pole piece and the respective pole through the interposition of a plate of thermal insulation material that resists high temperatures provided at each pole with a rectangular window slightly smaller in size than the pole itself, with the top sides of the pole pieces and/or the bottom sides of the poles being provided with peripheral recesses suitable to act as seats for the positioning of the plate.

    摘要： Die vorliegende Erfindung betrifft einen Hebemagnet (1) zur kraftschlüssigen Aufnahme von magnetischer Last. Der Hebemagnet (1) umfasst mindestens einen Stator (10) mit einem ersten permanentmagnetischen Element (11), mindestens einen dem Stator (10) zugeordneten Rotor (20) mit einem zweiten permanentmagnetischen Element (21) und mindestens ein Anlageelement (35) zur Aufnahme der Last, wobei der mindestens eine Rotor (20) mittels eines Drehantriebs (40) relativ zum Stator (10) aus einer Aufnahmeposition, in welcher durch das erste und zweite permanentmagnetische Element (21) eine magnetische Kraft zur Aufnahme der Last am Anlageelement (35) zur Verfügung gestellt ist, in eine Freigabeposition, in welcher die magnetische Kraft die Last freigebend reduziert ist, rotierbar ist. Das erste permanentmagnetische Element (11) des Stators (10) schliesst sich in Hauptwirkrichtung der magnetischen Kraft auf die Last an das zweite permanentmagnetischen Element (21) des Rotor (20) an und liegt zwischen dem zweiten permanentmagnetischen Element (21) des Rotors (20) und dem Anlageelement (35).
