PROBLEM TO BE SOLVED: To provide a rotor laminated core for a reluctance motor having a large mechanical strength and being capable of being sufficiently applied to a centrifugal force by a rotation without the complication of a manufacture and an increase in a cost with the charging of a non-magnetic substance in a conventional rotor laminated core. SOLUTION: In the rotor laminated core 10 for the reluctance motor, arcuate flux barriers 11b for core pieces 11 are composed of arcuate irregular stepped sections combining caulking sections. In the rotor laminated core for the reluctance motor, the arcuate flux barriers for the iron pieces are composed of arcuate irregular stepped sections combining the caulking sections and arcuate slits. In the rotor laminated core for the reluctance motor, through-holes are formed at the arcuate irregular stepped sections. COPYRIGHT: (C)2009,JPO&INPIT
