    摘要： The invention relates to an electrical machine having a stator winding, its manufacturing method and manufacturing apparatus, wherein the winding is manufactured with a predetermined number of coils on automated winding machines and is then embossed in the region of the longitudinal sides of the coils such that the longitudinal sides (17b), which have a plurality of conductors, of the coils (17), in terms of their cross section, are pressed and deformed into the subsequent slot shape. In order to achieve an extent of the coil conductors (18) without any intersections in the region of the longitudinal sides (17b) of the coils, the invention proposes first inserting the coils (17) in a preliminary embossing station (25) with their longitudinal sides into embossing chambers (23) of an embossing die (20), whose width corresponds to the width of at least two adjacent conductors, wherein the embossing chambers are then closed by an embossing stamp (26) to such an extent that, in the process, the conductors are aligned parallel to one another without any deformation of the cross section, before they are embossed into the final slot shape in a subsequent embossing station.

    摘要： The invention relates to an electric machine comprising a claw-pole rotor, particularly an electrically excited, at least 12-pole claw-pole machine (10) for a motor vehicle. The stator (16) of the machine, the winding of which has multiple phase windings and is connected to a rectifier arrangement (69) or alternatively to a pulse-controlled inverter arrangement using the phase winding connections (80 to 84) of said winding, has an inner diameter (Di) that is smaller than the associated outer diameter (Da) of the machine by a factor of 0.70 to 0.77, preferably by a factor of 0.73 to 0.75, at least in the groove center. According to the invention, the ratio of the groove widths (Bn2) at the groove openings (37) to the groove widths (Bn1) at the respective groove base (36) lies in the range of 0.69 to 0.81, preferably in the range of 0.73 to 0.78.

    摘要： The invention relates to a polyphase electrical machine, in particular a polyphase generator with a stator, which has a core element having a circumferential slot pitch and a winding arrangement with a plurality of windings. It is provided that each winding (45, 46, 47, 48, 49) and each slot (35, 36, 37, 38, 39) of the group of slots extending over a pole pitch is associated with one of the phases, and the windings (45, 46, 47, 48, 49) have winding sections (55) lying in associated slots (35, 36, 37, 38, 39), between which winding sections in each case one end winding connection (56) is formed, wherein the end winding connections (56) of different windings (45, 46, 47, 48, 49) are arranged radially with respect to one another in terms of position, and the number of phases is five. Furthermore, the invention relates to a method for producing a polyphase electrical machine.

    摘要： The invention relates to an alternating current generator, particularly a three-phase current generator for a motor vehicle, comprising a rotor (20) with north and south poles, particularly with claw pole fingers (24, 25) extending in the axial direction, wherein the fingers alternate on the circumference of the rotor (20) as north and south poles, a stator (16), which has a magnetic core, particularly a laminated core (17), grooves (15), and a stator winding (18) disposed in the grooves (15) of the magnetic core. The stator winding (18) comprises end windings (45, 46), which can be cooled by a substantially radial air flow, which is produced by at least one fan (30) provided on the rotor (20), wherein the stator (16) is disposed opposite of the rotor (20) and wherein the stator (16) and the rotor (20) have defined positions in relation to one another. The multi-phase stator winding (18) is made of winding elements (60, 61, 62, 63, 64, 65, 66, 67), wherein at least one winding element has more than two sections inserted in grooves, and wherein at least one winding element (60, 61, 62, 63, 64, 65, 66, 67) has more than one reversal section, which brings about a change in the radial position.
