Abstract
A rotor for a rotary electric machine, capable of rotating around an axis of rotation, the rotor has first and second axial ends and includes a rotor body having a plurality of teeth circumferentially distributed around the axis and projecting radially, each tooth being in contact with two end plates. Also included is a rotor winding having a plurality of coils, each coil being wound on one of said teeth of the rotor body, each coil having two coil ends, two covers, a first cover located on the first axial end of the rotor and a second cover located on the second axial end of the rotor. The rotor has at least one non-conductive radial barrier that maintains a predetermined distance between the first coil end and the first cover on the one hand and between the second coil end and the second cover on the other hand.
