摘要： In order to fix the stator assembly (20) in a three-phase current alternator, the stator is provided with a decoupling ring (21) on the one side fixedly attached to the stator assembly (20) and on the other side gripped in a cavity (22) in the two side pieces (12', 13') of the three-phase current alternator casing. The decoupling ring (21) may consist of two annular decoupling segments (21a, 21b) which surround the stator assembly (20) and form, at a certain distance from the latter, a common insertion surface for the flange A and B (12', 13') of the casing, or it may take the shape of a radial ring (29) connected on its circumference in an alternating manner once fixedly with the stator assembly (20') and then by means of coupling segments (B) with specific gripping points in the casing. The half-shells (21a, 21b) of the decoupling ring (21) and the radial ring (29) may both be directly shaped by the plates of the stator assembly (20, 20').

摘要： Il est proposé une machine électrique à ventilation forcée dans laquelle, pour l'évacuation de la chaleur de dissipation produite dans la machine (10), le carter de machine (17, 18) présente des orifices (32, 39 et 41) pour l'entrée et la sortie du flux d'air de refroidissement (40) amené depuis l'extérieur. Pour l'amélioration de l'effet de refroidissement et pour la diminution des bruits d'écoulement aérodynamique, il est prévu d'entourer sur les faces frontales de l'empilage de tôles statoriques (12) la tête de bobine (13a, 13b) d'un conduit de ventilation de forme annulaire (33, 34) lequel présente au moins un orifice d'entrée (39) et au moins un orifice de sortie (41) pour un flux d'air de refroidissement tournant autour de la tête de bobine dans le sens de la circonférence. Les conduits de ventilation (33, 34) sont alors d'une part formés par le carter de machine (17, 18) et d'autre part délimités, côté rotor, par une paroi annulaire (35, 36) insérée entre l'empilage de tôles (12) et un flasque du carter (17, 18).

摘要： The electrical motor, especially a three-phase alternator, has a stator (21) fixed in a housing (10) and a claw-pole rotor (23) having an exciting winding (28) and fixed on a shaft (13). An electric transformer (29) for exciting the exciting winding (28) -s placed between the claw-pole rotor and an end shield (17) closing the housing. The primary winding (30) is disposed together with the core (36, 41, 47) on the end shield (17). The primary and secondary windings (30, 31) of the transformer (29) are disposed between the end shield (17) and the claw-pole rotor system (23), wherein the primary winding (30) is disposed in a stationary core (36, 41, 47) and the secondary winding (31) is arranged on a rotary core (35, 42, 48) coupled by means of an air gap (38).

摘要： Proposed is an electrical machine with external air cooling, the machine housing (17, 18) having openings (32, 39, 41) for the intake and exhaust of an external cooling-air flow (40) to ensure the removal of the waste heat generated in the machine (10). In order to improve the cooling efficiency and reduce air-flow noise, the coil (13a, 13b) at the ends of the stator plates (12) is surrounded by an annular air conduit (33, 34) with at least one inlet aperture (39) and at least one outlet aperture (41) for a cooling-air stream which passes over the surface of the end coil. The air conduits (33, 34) are formed by the machine housing (17, 18) and separated from the rotor by an annular partition (35, 36) located between the stator plates (12) and a bearing bracket mounted on the housing (17, 18).

摘要： An electric machine, especially a three-phase generator, with an exciter (26) in the form of a claw-pole machine that delivers a required exciting current for a generator. The exciter is arranged to the side of the generator and its dimensions are substantially smaller than those of the latter. Permanent magnets (39) are arranged close to the claws (28,29) of the stator (28,29) facing the armature (32) of the exciter in a magnetic dispersion area in between said claws, thereby enabling undesirable stray fields to be terminated.

摘要： Pour fixer l'ensemble de stator (20) dans un alternateur à courant triphasé, le stator est pourvu d'un anneau de découplage (21) fixement retenu à l'ensemble de stator (20) d'une part et encastré d'autre part dans un creux (22) des deux parties latérales (12', 13') de l'enveloppe de l'alternateur à courant triphasé. L'anneau de découplage (21) peut se composer de deux segments annulaires de découplage (21a, 21b) qui entourent l'ensemble de stator (20) et forment à une certaine distance de celui-ci une surface commune d'encastrement pour la flasque A et B (12', 13') de l'enveloppe, ou il peut prendre la forme d'un anneau radial (29) relié à sa circonférence alternativement de manière fixe avec l'ensemble de stator (20') et par l'intermédiaire de segments de couplage (B) avec des points précis d'encastrement dans l'enveloppe. Aussi bien les demi-coques (21a, 21b) de l'anneau de découplage (21) que l'anneau radial (29) peuvent être directement façonnés dans les lames de l'ensemble de stator (20, 20').
