INTERNALLY-VENTILATED POLYPHASE STATOR AND ELECTRICAL MACHINE COMPRISING SUCH A STATOR

摘要

The polyphase stator for an internally ventilated rotating electrical machine comprises a body (14) provided with slots and carrying a coil (12) having at least one winding per phase, which comprises: a plurality of pairs of lateral branches each intended to be mounted in a slot of the body (14); a plurality of connecting heads (50 to 55) extending outside the body (14) so as to form a first lead-out (42) and interconnect each pair of lateral branches; a plurality of coupling feet (150 to 155) offset circumferentially with respect to the plurality of connecting heads and extending outside the body (14) so as to form a second lead-out (43) and interconnect each pair of lateral branches; one of said pluralities having a generally pointed shape and having an axial length of between 15 and 20 mm. The rotating electrical machine comprises such a stator. Application: Stator and alternator or an alternator-starter of a motor vehicle.
