Abstract
The invention relates to a rotor for a synchronous reluctance electric machine. It includes a stack of consecutive magnetically conductive core elements; each core element includes at least two adjacent sectorial sections with flux barriers and a central area surrounding the rotational axis. A binding structure includes core end plates which form together with interconnection casts a unitary casted structure. The interconnection casts are casted into channels extending through the stack and which are located in an area defined by the flux barriers of the adjacent sectorial sections and the central area of each core element.
