A rotor for an electric machine, wherein the rotor comprises a plurality of stack elements and each of the stack elements includes material of first magnetic conductance. Each of the stack elements includes a plurality of sectorial sections distributed round a rotational axis of the rotor. Each of the sectorial sections includes one or more flux barriers. At least one of the one or more flux barriers has a difference associated with filing of an electrically conductive material of third magnetic conductance in different sectorial halves of a common sectorial section, the first magnetic conductance being larger than the third magnetic conductance.
