Abstract
A rotary electrical machine comprising a rotor and a stator (1). The stator comprises a tooth (21) delimited by notches (22), and a winding composed of n×M wires (3), wherein n corresponds to a number of phases and is equal to at least 2, and M corresponds to a number of continuous electric wires for each phase (3) and is equal to at least one. The winding is composed of successive turns, each of the successive turns comprising n×M wires wound simultaneously in n of the notches (22) to be inserted in n series of notches. Each of the series of the notches is dedicated to a single phase, and for each of the successive turns, each of the assembly of the M wires (3) constitutes a phase and is inserted in the same series of the notches (22).
