Abstract
(DE)
Die Erfindung betrifft eine magnetisch aktive Einheit (100) einer elektrischen Maschine (140) mit wenigstens zwei Polen (101,102,103,104), mit - einem Blechpaket (154) mit Nuten (1 bis 63), und - wenigstens einer Wicklung (116,118,120) für eine jeweilige der Phasen (L,M,K), wobei die Wicklungen (116,118,120) einen elektrischen Leiter aufweisen, der Spulengruppen (122,124,126,128) in den Nuten (1 bis 63) ausbildet, wodurch Spulen der Spulengruppen (122,124,126,128) ausgebildet sind, - wobei in den Nuten (1 bis 63) wenigstens zwei Abschnitte der elektrischen Leiter von wenigstens einer der Wicklungen (116,118,120) voneinander elektrisch isoliert angeordnet sind, und wenigstens eine erste der Spulengruppen (124) einer der Wicklungen (116,118,120) eine erste Anzahl von Spulen aufweist, die von einer zweiten Anzahl von Spulen einer zweiten der Spulengruppen (126) der gleichen Wicklung (116,118,120) abweicht.
(EN)
The invention relates to a magnetically active unit (100) of an electric machine (140) with at least two poles (101, 102, 103, 104), comprising - a laminated core (154) with grooves (1 to 63), and - at least one winding (116, 118, 120) for each of the phases (L, M, K), said windings (116, 118, 120) having an electric conductor which forms coil groups (122, 124, 126, 128) in the grooves (1 to 63), whereby coils of the coil groups (122, 124, 126, 128) are formed, wherein - at least two sections of the electric conductors of at least one of the windings (116, 118, 120) are arranged so as to be electrically insulated from each other in the grooves (1 to 63), and at least one first coil group of the coil groups (124) of one of the windings (116, 118, 120) has a first number of coils which deviates from a second number of coils of a second coil group of the coil groups (126) of the same winding (116, 118, 120).
(FR)
L'invention concerne une unité active magnétiquement (100) d'une machine électrique (140) dotée d'au moins deux pôles (101, 102, 103, 104), comprenant - un noyau feuilleté (154) comprenant des rainures (1 à 63) et - au moins un enroulement (116,118, 120) pour chacune des phases (L,M, K), les enroulements (116,118, 120) comportent un conducteur électrique formant des groupes de bobines (122,124, 126,128) dans les rainures (1 à 63), ce qui permet de former des bobines des groupes de bobines (122,124, 126,128), dans les rainures (1 à 63), au moins deux parties des conducteurs électriques d'au moins un des enroulements (116,118, 120) sont isolées électriquement l’une de l’autre, et au moins un premier des groupes de bobines (124) de l’un des enroulements (116,118, 120) comporte un premier nombre de bobines qui s’écarte d’un deuxième nombre de bobines d’un deuxième groupe de bobines (126) du même enroulement (116,118, 120).
