A rotor for a rotating machine having a number n of poles pairs p that define corresponding direct pole axis (D-axis) and quadrature axis (Q-axis), and including a rotor core having a plurality of magnetically conductive laminations stacked in a rotor axial direction z. The magnetically conductive laminations include cut-out portions forming a plurality of flux barriers extending continuously with respect to the Q axis from a first rim portion to a second rim portion of the magnetically conductive laminations, the flux barriers being radially alternated by flux paths. The plurality of flux barriers form a corresponding plurality of cavities extending in the rotor core along the axial direction z, at least some of the plurality of cavities being filled with an electrically conductive and magnetically non-conductive material. The rotor further includes a plurality of channels spaced circumferentially and along the axial direction z, each of the channels transversally connecting two adjacent cavities of the plurality of cavities, at least some of the channels being filled with a non-magnetically conductive material.
