Publication number: 20220252105Abstract: An assembly for a rotary electric machine includes a bracket having a recess for a rolling bearing, and a preloading member for preloading the rolling bearing, intended to be disposed axially between the end wall of the recess and the rolling bearing. Also included is a holding member for holding the rolling bearing, intended to be disposed radially between the rolling bearing and a lateral wall of the recess. The holding member for holding the rolling bearing is arranged so as to make it possible to axially hold the preloading member in the recess of the bracket before the rolling bearing is inserted into the recess, during a phase of assembly of the rotary electric machine.Type: ApplicationFiled: June 23, 2020Publication date: August 11, 2022Applicant: VALEO EQUIPEMENTS ELECTRIQUES MOTEURInventors: Alexis RIVALS, Jean-Claude LABROSSE

Patent number: 11128085Abstract: The subject matter of the present invention is a sealing system configured to form a leak tight electrical connection on a face of an electrical equipment, said sealing system including: a base, comprising a first plate, comprising a through orifice of which the edge is continually comprised in a face of said first plate, a plug comprising a second plate comprising at least one through hole, configured for the passage of at least one electric wire, and a part projecting from said plate suited to being inserted into the orifice, a face of the second plate coming against a face of the first plate, said plug having a flexibility greater than the flexibility of the base, such that the difference in flexibility ensures a constraining of the second plate on the first plate, in such a way as to ensure the sealing of the electrical equipment.Type: GrantFiled: December 13, 2019Date of Patent: September 21, 2021Assignee: VALEO SIEMENS EAUTOMOTIVE GERMANY GMBHInventors: Cédric Ledieu, Jean-Claude Labrosse

Patent number: 9871420Abstract: A rotor (1) comprising a plurality of alternating magnetic poles formed by permanent magnets (3) distributed regularly between a circumferential portion (5) and a central portion (6) of the magnetic body (2) of the rotor and defining circumferential pole sections (7). The pole sections have a pre-determined pole pitch (Thetarho) and comprise a lobe-forming radial section (8). The lobe-forming radial section partially covers the magnets, such as to maximize a useful magnetic flux (PhiU) flowing radially through each of the pole sections and to minimize a leakage magnetic flux flowing through the circumferential portion. The pole sections can have a pre-determined pole overlap angle (Thetar) such as to maximize the useful magnetic flux (PhiU) and to minimize the leakage magnetic flux (PhiL), said overlap angle (Thetar) being a viewing angle of the lobe (8) from a point on the axis of the rotor.Type: GrantFiled: October 30, 2012Date of Patent: January 16, 2018Assignee: Valeo Equipements Electriques MoteurInventors: Lilya Bouarroudj, Jean-Claude Matt, Jean-Claude Labrosse

Patent number: 9641031Abstract: A rotor (1) comprising a plurality of alternating magnetic poles formed by permanent magnets (3) distributed regularly between a circumferential portion (5) and a central portion (6) of the magnetic body (2) of the rotor and defining circumferential pole sections (7). The circumferential portion comprises axial grooves (15) which are arranged between the pole sections facing the magnets and which form openings in recesses (4) containing the magnets. The openings have a pre-determined first width (a) such as to minimize a leakage magnetic flux (PhiL) flowing through the circumferential portion (5) and to maximize a useful magnetic flux (PhiU) flowing radially through each of the pole sections (7).Type: GrantFiled: November 6, 2012Date of Patent: May 2, 2017Assignee: Valeo Equipements Electriques MoteurInventors: Lilya Bouarroudj, Jean-Claude Matt, Jean-Claude Labrosse
