摘要:
A method for producing a claw-pole rotor, including: a step of mounting polar wheels on the shaft in such a way that each tooth of a polar wheel is located in the existing space between two consecutive teeth of the other polar wheel; a step of machining the lateral faces facing two adjacent teeth, whereby an axial groove is machined in each lateral face; and a step of mounting a magnetic element between two adjacent teeth such that the magnetic element is received in the axial grooves. The method is characterized in that the step of machining lateral faces is carried out before the step of mounting polar wheels on the shaft. The invention also relates to a rotor obtained by such a method.

This process for assembling conductive segments (16) of a rotor or stator winding of a rotary electrical machine comprises the stages consisting in inserting the conductive segments (16) in slots arranged in a core (12) of the rotor or of the stator in such a way that the conductive segments project beyond the latter by their free ends, and in welding the conductive segments in pairs by their projecting free ends to form a winding (14) around the rotor or the stator.The conductive segments each being formed by a wire of electrically conductive material covered with a layer of electrically insulating material, the layer of electrically insulating material is eliminated, in the zone in which the conductive segments are welded, by the means used to weld the latter.Application to the assembly of conductive segments of a rotor or stator winding of a motor-vehicle alternator.

In this method, a vertical stack is formed on an axis coinciding substantially with the gravity direction and comprising, from top to bottom: the element; the mass in a solid state; and the substrate. The mass is then heated so as to cause it to pass into a liquid state enabling it to spread on the substrate. More particularly, after the stack has been formed, the element is left free to move vertically, and during heating, variation in the vertical position of the element is measured.

The invention concerns an arrangement for welding a rotating electrical machine winding consisting of a plurality of conductive segments supported on a supporting body (1) so that the ends of each pair of conductive segments to be welded are juxtaposed in a radial direction and arranged in radial rows (R) circumferentially offset relative to one another, said welding arrangement including an equipment for flanging the ends of the conductive segments to be welded, comprising circumferential locking means formed by cam-shaped portions (19) of flanging members (13, 13′), a cam portion (19) being configured so as to be urged to come into clamped position between the ends of two radial rows (R) by rotation of the flanging member. The invention is applicable to a motor vehicle alternator.

The invention relates to a device for assembling, by screwing, a drive member, such as a drive pulley, with a shaft intended to be coupled to the rotor of a rotating electrical machine, the device including an additional, welded connection. According to the invention, this method of producing the assembly device is characterized in that the drive member screwed onto its shaft in the vertical position is welded from below. The invention can be used for rotating electrical machines, such as an alternator or a starter-alternator of a motor vehicle.
