Abstract

A rotor for a reluctance motor includes a laminated core having a number of rotor sheet metal blanks. Each rotor sheet metal blank includes flux barriers cast with a non-ferromagnetic casting compound and at least one soft-magnetic rotor sheet which delimits the flux barriers. Flux barriers of adjacent rotor sheet metal blanks are arranged offset relative to one another so that the flux barriers of one of the adjacent rotor sheet metal blanks are delimited in an axial direction at least partially by the rotor sheets of the other one of the adjacent rotor sheet metal blanks, with the casting compound of the flux barriers adhering in an adhesion zone to the rotor sheets.
