ROTOR LAMINATED CORE FOR RELUCTANCE MOTOR

PROBLEM TO BE SOLVED: To provide a rotor laminated core for a reluctance motor which has a plurality of arc-shaped slits, in a concentric shape with a rotating shaft-hole side protruded, has laminated core pieces which are formed by arranging the plurality of arc-shaped slits at the circumference of a rotating shaft hole at intervals, is rotated by reluctance torque which is generated on the basis of a difference between a salient pole direction, where magnetic flux easily flows along the extension direction of the arc-shaped slits, and a non-salient pole direction where the magnetic flux is difficult to flow along the parallel arrangement direction of the arc-shaped slits, and can suppress to a minimum level the torque variations of rotor at the operation of the motor, without employing a multi-layer slit structure which is narrow in slit width and slit interval. SOLUTION: This rotor laminated core for the reluctance motor is such that ends of the plurality of arc-shaped slits are formed at equal intervals along the entire periphery of the core pieces.
