Title
(EN) ELECTRIC MACHINE WITH STATOR HAVING MULTI-TIERED END TURNS
(FR) MACHINE ÉLECTRIQUE AVEC STATOR AYANT DES SPIRES D'EXTRÉMITÉ À PLUSIEURS NIVEAUX
Abstract
(EN) An electric machine (20) having a stator (26) with windings (30) all having the same length. The stator includes a plurality of slots (32). A plurality of windings are mounted in the slots of the stator core and define a plurality of poles circumferentially distributed about the stator core (28). Each winding defines at least a first wrap and a second wrap wherein each of the first and second wraps circumscribes the stator core. Each of the first and second wraps includes a wire segment disposed in a slot in each pole. The first wrap of each winding is primarily disposed in one of the layers and the second wrap of each winding is primarily disposed in a different one of the layers. The first wrap of each winding defines a first linear length (X + Y) and the second wrap of each winding defines a second linear length (X) that differs from the first linear length.
(FR) L'invention concerne une machine électrique (20) ayant un stator (26) avec des enroulements (30) ayant tous la même longueur. Le stator comprend une pluralité de fentes (32). Une pluralité d'enroulements sont montés dans les fentes du noyau de stator et définissent une pluralité de pôles répartis de façon circonférentielle autour du noyau de stator (28). Chaque enroulement définit au moins une première spire et une seconde spire, chacune des première et seconde spires circonscrivant le noyau de stator. Chacune des première et seconde spires comprend un segment de fil disposé dans une fente dans chaque pôle. La première spire de chaque enroulement est principalement disposée dans l'une des couches et la seconde spire de chaque enroulement est principalement disposée dans une couche différente parmi les couches. La première spire de chaque enroulement définit une première longueur linéaire (X + Y) et la seconde spire de chaque enroulement définit une seconde longueur linéaire (X) qui diffère de la première longueur linéaire.
