Definitions

  • the ribs reduce the average gap distance between the expansion plate and the movable pallet, which allows effective control of the position of the pallet, with an increase in the magnetic field generated by the coil. constant power.
  • the geometry of the ribs makes it possible to reduce the moving mass and, consequently, to increase the magnetic force at equivalent power and to reduce the intensity of the magnetic force required to maneuver the pallet.
  • the invention also makes it possible to increase the stored electromagnetic energy before the impact of these pads. Because of the reduced air gap, the magnetic circuit is generally closed between the expansion plate and the movable pallet, which induces an increase in the electromagnetic force.
  • the rib extends over the entire length of the edge at which it is arranged.
