  • Patent number: 11791686
    Abstract: The invention mainly concerns a rotating electrical machine, in particular for a motor vehicle, comprising a bearing (15) comprising a recess (17) for receiving a shaft bearing guiding the rotation of the shaft, characterised in that the bearing (15) comprises: —a first part (15. I) produced from a first material comprising: —the recess (17) for receiving the shaft bearing, —an interface (51) for mounting a bearing (50) of a pinion (49) external to the rotating electrical machine, and —a second part (15.2) produced from a second material comprising: —a transverse wall (53), and —a skirt (54) extending from the transverse wall (53) at least partially surrounding the stator (11), —the second part (15.2) being overmoulded on the first part (15.1) so as to form a strong bearing (15).

  • Publication number: 20220252105
    Abstract: 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.

  • Patent number: 11128085
    Abstract: 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.

  • Patent number: 10840765
    Abstract: The invention primarily relates to an assembly, in particular for a hybrid vehicle, wherein the assembly comprises; an enclosure (46) for receiving a coolant liquid and having an opening (49) for bringing the inside of the enclosure (46) into communication with the outside of the enclosure (46), a rotary electric machine (10) arranged in the enclosure (46) able to be cooled by the coolant liquid, an electrical connector element (51) arranged to be electrically connected to the rotary electric machine (10), the connector element (51) being sealingly mounted in the opening (49) of the enclosure (46) in such a way that the connector element (51) participates in the sealing that prevents the liquid from flowing from the inside of the enclosure (46) to the outside of the enclosure (46) via the opening (49).

  • Patent number: 9871420
    Abstract: 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.

  • Patent number: 9641031
    Abstract: 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).
