Abstract
A rotor of a rotating electrical machine includes a plurality of poles each extending on a first axis that is radial with respect to the rotor and on a second axis parallel to the rotor with respect to the rotor, each pole comprising a pole body, a rotor winding for each pole, positioned against the body of the pole, the rotor winding taking the form of a strip extending over the length of the pole body on the radial first axis wound against the pole body, a plurality of closure shims, a closure shim of the plurality of closure shims being in contact with a rotor winding associated with a pole body, the closure shim being configured to exert a pressure on the rotor winding towards the pole body.
