Definitions

  • the subject of the invention is a magnetic device, the applications of which can be multiple, but the arrangement and characteristics of which make it more particularly intended for handling loads.
  • FIG. 1 These two positions are represented the first by FIG. 1 and the second by FIG. 2, in which (A1) and (A2) denote the magnets of the stator and of the rotor respectively and in which the lines of force of the magnetic field are visible.
  • the invention aims to simplify the manufacture of this type of magnetic device. It relates to an assembly whose rotor has a magnetic mass greater than that of the stator and whose rotor is positioned in the stator with a clearance allowing the formation of an air gap compensating for the imbalance between the magnetic masses of the stator and the rotor.
  • Figure 3 is a principle view
  • Figures 4, 5 and 6 are views in longitudinal section, in cross section and partial in elevation.
  • FIG. 3 The principle serving as a basis for the arrangement and operation of this magnetic carrier is illustrated in FIG. 3.
  • the stator and the rotor of the carrier are designated respectively by (1) and by (2).
  • the stator (1) consists of a cage comprising two pole pieces (3), two magnets (4) and a pole closure plate (5).
  • the rotor (2) consists of a magnet (6) and two pole pieces (7); it is movable in rotation about an axis (X).
  • the correct functioning of the magnetic carrier therefore only requires determining the magnetic masses of the magnets of the stator and of the rotor as a function of the air gap resulting from the clearance voluntarily left between them; and thanks to this game it is possible to manufacture the carrier without requiring expensive machining of its stator and its rotor.
  • Figures 4 and 5 show an embodiment of such a magnetic carrier. It comprises a cage delimited by two lateral ferromagnetic plates (8), by two non-magnetic flanges (9), by a non-magnetic base (10) and by three ferromagnetic plates (12) of which the two lower ones are isolated from one another and between which are positioned three magnets (13).
  • a ring (14) is attached to this cage for suspending the carrier from a lifting member, and a handle (15) for moving it when it is suspended.
  • This cage constitutes the stator inside which is housed the rotor which can occupy two positions corresponding respectively to the stop and the walk.
  • This rotor which revolves in the flanges (9) of the stator is constituted by magnets (16) and pole plates (17).
  • a handle (18) allows it to be rotated to move the carrier from the "off” position to the "on” position and vice versa; and a finger (19) allows it to be locked in the "on” position.
  • the invention is not limited to the only embodiment of this magnetic carrier which has been described above by way of example, on the contrary it embraces all the variant embodiments within the framework of the claims below, regardless in particular of the type of magnets used and the arrangement of these magnets in the stator.
