gripper arrangement or sustaining loads, permanently magnetic mind

摘要

The invention is directed to an electrically controllable permanent magnetic quick break switching system for raising, transporting and stacking ferromagnetic parts. The system includes a magnetized permanent magnet 1 centrally arranged in the direction of its smallest dimension in a magnetically conducting iron support member, on which magnet there sits a magnetically conducting compensation plate 5 having a magnetically conducting bar 3 and magnetically conducting central pole 6 and additionally an electrical coil 4 between the compensation plate and the control pole for compensation (displacement) of the magnetic field from the region of the working air gap 7. For optimum compensation, i.e., of the most extensive delay free releasing of ferromagnetic thick to thinnest parts with simultaneously high forces the structural dimensions of the system are in reciprocal relationships which are individually stated in claim 1.
