Patent number: 10393174Abstract: A thrust disc for a magnetic bearing, wherein the thrust disc comprises: a body, which is adapted to be mounted on a shaft and which has a first offset yield strength and a first magnetic permeability, and at least one flange which is fixed to the body in a position where it can interact with a thrust stator in order to form a magnetic bearing and which has a second offset yield strength and a second magnetic permeability; wherein the first offset yield strength is higher than the second offset yield strength; and wherein the first magnetic permeability is smaller than the second magnetic permeability. Additionally, the magnetic bearing can be equipped with such a thrust disc. An apparatus can be equipped with such a magnetic bearing.Type: GrantFiled: December 16, 2014Date of Patent: August 27, 2019Assignee: SKF Magnetic MechatronicsInventors: Luc Baudelocque, Mohamed Bendaoud, Matthieu Oliva

Patent number: 9746027Abstract: An assembly includes a rotating shaft supported with respect to a stationary housing by at least one active magnetic bearing presenting a mean radial air gap and at least one auxiliary bearing having first and second coaxially arranged annular surfaces is provided. One of the first and second coaxially arranged annular surfaces defines a clearance (E2) with one of the stationary housing and the rotating shaft, the clearance (E2) being less than the mean radial air gap and the other of the first and second coaxially arranged annular surfaces being integral with the other one of the stationary housing and the rotating shaft. The auxiliary bearing provides a first ball bearing and a second ball bearing having a misalignment with respect to each other in order to increase the starting torque.Type: GrantFiled: July 28, 2014Date of Patent: August 29, 2017Assignee: SKF MAGNETIC MECHATRONICSInventors: Jens Anders, Mohamed Bendaoud, Joaquim Da Silva, Matthieu Oliva, Frederic Ponson

Patent number: 9660374Abstract: An electrical connector providing a sealed electrical link between an inside environment subjected to corrosive gases or liquids under pressure and an outside environment of different pressure. The connector includes a connector body, conductor cables, a thermoplastic insulator, and a sealing element. The connector body is secured to a structure and includes insulating feed-throughs for receiving electrical contacts connecting an outside environment to an inside environment. The conductor cables, comprising an outer insulating layer made of a fusible thermoplastic material, are connected to said electrical contacts inside said inside environment. The thermoplastic insulator is secured to said connector body and surrounds the conductor cables. The thermoplastic insulator and cable outer insulating layers are made of a same type of fusible thermoplastic material making it possible, by localized fusion, to form a thermoplastic weld therebetween.Type: GrantFiled: July 26, 2013Date of Patent: May 23, 2017Assignee: AKTIEBOLAGET SKFInventors: Luc Baudelocque, David Moulin, Mohamed Bendaoud, Bruno Tellier
