Conformément à l'invention, la séparation de chaque faisceau (FU) est effectuée dans une zone de séparation (SU) située à proximité d'une connexion d'un ou plusieurs fils du faisceau (FU) avec une sortie (U3) d'une des bobines appartenant à la phase correspondant audit faisceau, en sorte que les gaines isolantes (40) s'étendant suivant la circonférence du stator (10) depuis la zone de séparation (SU) à une sortie (U2, U4) d'une prochaine bobine d'une phase ou entre les sorties de deux bobines (28) successives de ladite phase présentent toutes une longueur sensiblement identique les unes par rapport aux autres. The invention is primarily concerned with a stator (10) for a polyphase rotating electrical machine comprising a set of coils wound around stator teeth each having an input and an output having one or more wires in parallel. The input is intended to be interconnected with other inputs to form the neutral point of the machine and the output is intended to be interconnected with other outputs to form one of the phases ( ...

Insulating element for electric machine stator

The invention essentially concerns an insulating element (200) for a stator (300) of an electric machine, characterized in that it comprises: an annular support (201); and arms (202) distributed circumferentially about the support (201) and extending radially relative thereto from the internal periphery of the support (201) towards the interior of the insulating element; as well as flanges (205) extending on either side of the arms (202), the insulating element (200) having an abutment face (207) which is to be placed against an end face of the stator (300).
