ROTARY ELECTRICAL MACHINE STATOR PROVIDED WITH A COIL WITH AT LEAST ONE SHIELDED PHASE WINDING

摘要

The invention relates mainly to a rotary electrical machine stator, in particular for a motor vehicle, comprising:a stator body (11) with a central axis, the stator body (11) comprising a series of notches (15);a winding wound in the notches (15) in the stator body (11) forming a first chignon (231) and a second chignon (232) extending axially on both sides of the stator body (11); wherein at least one of the phase windings (PH1-PH3, PH1′-PH3′) is a shielded winding which comprises all the active portions (20) of the layer (C1, CN) situated at one of the radial ends at least of each notch (15) of the series, each extended firstly by a corresponding connection portion (21) of the first chignon (231), and secondly by a corresponding connection portion (21) of the second chignon (232).
