Stator winding comprising multiple phase windings

A method is disclosed for producing a stator winding of an electric machine, in particular an alternator, the stator winding comprising at least one phase winding and the phase winding having a plurality of coils, the plurality of coils being wound in one direction, a given number of turns being wound and the coil having a plurality of coil sides, two coil sides of the coil transitioning integrally into coil connectors. The turns of the coil are subsequently moved relative to each other in such a way that the coil sides transitioning into coil connectors are outermost coil sides of the coil.

An alternating-current generator, in particular a three-phase generator, for a motor vehicle, having a rotor including north and south poles, particularly having claw-pole fingers extending in the axial direction and alternating as north and south poles at the rotor's periphery, a stator having a magnetic core, especially laminated core, having slots and a stator winding disposed in the magnetic core's slots, the stator winding having winding overhangs that are coolable by an approximately radial air flow produced by at least one fan mounted at the rotor, the stator being situated opposite the rotor, and the stator and the rotor having defined positions relative to each other, the multiphase stator winding being made up of winding elements, at least one winding element having more than two sections inserted in slots, and at least one winding element having more than one reversal section which brings about a change in the radial position.

Alternating-current generator having a stator and a stator winding made of winding elements inserted in stator slots and a method for producing a stator of the present invention

In a method for manufacturing a bar winding for the stator of an electric machine, in particular of a claw pole alternator for motor vehicles, resistance welding is used to form mechanically and electrically reliable and permanent connections in the winding overhang of the stator even with winding configurations that include four or more superposed conductor segments, and even with the very small amount of working space that remains for the necessary connections, using a minimum of production-related outlay. With a design, in particular, of four radially superposed conductor segments in the winding overhang, particularly advantageous configurations result in terms of the placement of the bar ends and in terms of the design of the welding electrodes.
