Patent number: 10389199Abstract: A stator (1) of a rotary electric machine includes a body (2) provided with slots (15), a coil (3) constituted of windings (4, 5, 6, 7, 8) that include first conductive segments (19) equipped with two first branches and second conductive segments (25) provided with two second branches. Each conductive segment is coated with insulation except for the presence of a bared surface on each one of the branches. The shapes of the bared surfaces complement one another. The first and second conductive segments are arranged in a staggered configuration and in opposite directions successively one after the other, with each slot accepting first branches and second branches positioned opposite with the bared surfaces thereof respectively in contact with one another in such a way as to form a continuous wire. The stator includes elements for keeping the bared surfaces in contact with one another in the slots.Type: GrantFiled: April 28, 2015Date of Patent: August 20, 2019Assignee: SKYAZURInventor: Nicolas Langlard

Patent number: 9742231Abstract: A rotary electrical machine comprising a rotor and a stator (1). The stator comprises a tooth (21) delimited by notches (22), and a winding composed of n×M wires (3), wherein n corresponds to a number of phases and is equal to at least 2, and M corresponds to a number of continuous electric wires for each phase (3) and is equal to at least one. The winding is composed of successive turns, each of the successive turns comprising n×M wires wound simultaneously in n of the notches (22) to be inserted in n series of notches. Each of the series of the notches is dedicated to a single phase, and for each of the successive turns, each of the assembly of the M wires (3) constitutes a phase and is inserted in the same series of the notches (22).Type: GrantFiled: March 20, 2015Date of Patent: August 22, 2017Assignee: Valeo Equipements Electriques MoteurInventors: Xavier Dunesme, Jérôme Fournier, Jean-Pierre Chochoy, Ludovic Darras, Alain Defebvin, Stéphane De Clercq, Olivier Luittre, David Desmet, Nicolas Langlard
