Abstract

On connaît déjà un stator pour machine électrique, selon le brevet DE 103 15 361 A1, présentant des dents de stator et entre celles-ci des compartiments de type encoches dans lesquels est disposé au moins un enroulement de phase composé d'éléments conducteurs en U. Les éléments conducteurs présentent chacun une première branche de conducteur, une deuxième branche de conducteur et un arc de conducteur reliant les branches de conducteur, la première branche de conducteur étant disposée dans un premier compartiment de type encoche et la deuxième branche de conducteur étant disposée dans un deuxième compartiment de type encoche. L'inconvénient est que seuls deux éléments conducteurs sont disposés dans chaque compartiment de type encoche. Avec le stator selon l'invention, un nombre accru d'éléments conducteurs se trouvent dans un compartiment de type encoche, ce qui permet d'accroître le nombre de spires. Selon l'invention, l'enroulement de phase (4) est constitué d'un certain nombre de blocs (8) d'au moins deux éléments conducteurs (5) dont les premières branches de conducteur (5.1) sont disposées dans le même compartiment de type encoche (3) et dont les deuxièmes branches de conducteur (5.2) sont disposées dans le même autre compartiment de type encoche (3).
