Abstract
A rotating electric machine whereof the rotor includes a magnetic core provided with radial teeth, uniformly distributed at its periphery, annular magnets arranged on either side of the core axial ends and magnetic end flanges pressing the annular magnets against the core, magnetic bars linking the end flanges together, housed in the spaces between the radial teeth, additional magnets being interposed between each of the bars and at least the side walls of the core radial teeth defining the spaces. The stator includes a magnetic core, excitation coils arranged on either side of the core, a stator coil wound on the core and a magnetic ring in contact with the core and provided with radial rims co-operating with the axial rims of the rotor end flanges to form paths for the return flux.
