Patent number: 11706849Abstract: A shaping machine includes a melting vessel, an induction coil arranged on the melting vessel for inductively heating, in particular melting, a material, and a shaping cavity. The melting vessel has at least one irradiation region which is substantially permeable for an electromagnetic field, and the shaping machine is adapted to cool the material in the cavity in such a way that a substantially crystalline solid body is formed. A body with a higher magnetic permeability than the melting vessel is arranged overlapping the irradiation region, and the induction coil is arranged between the body and the irradiation region.Type: GrantFiled: June 6, 2016Date of Patent: July 18, 2023Assignee: ENGEL AUSTRIA GMBHInventors: Wolfgang Amrhein, Hubert Mitterhofer, Siegfried Silber, Werner Kappelmueller, Andreas Prokesch

Patent number: 9964147Abstract: A magnetic bearing for the mounting of a shaft, in particular for a spinning rotor of an open-end spinning device, features several pole shanks of a stator for the active radial magnetic mounting of the shaft in two degrees of freedom, which in each case are surrounded by a coil and are radially arranged to each other, in such a manner that they define an opening for the shaft. In the area of the opening, the pole shanks are connected to each other. For the passive axial mounting of the shaft, at least one permanent magnet is arranged between the coils and the opening. The invention also includes a shaft for mounting with at least one corresponding magnetic bearing. The shaft is a composite component, which at least partially consists of non-ferromagnetic material.
