Abstract
In the case of a laminated rotor core 10, insertion of permanent magnets 14 and filling of resin 15 into each of magnet insertion holes 13 are performed in order to cancel out a problem of an imbalanced weight estimated from a deviation of lamination thickness in a circumferential direction of a laminated core body 12, and a manufacturing method includes a step of measuring a deviation of lamination thickness in which an imbalanced weight is estimated by measuring the deviation of lamination thickness in the circumferential direction of the laminated core body 12, and a step of balance adjustment in which the insertion of the permanent magnets 14 into each of the magnet insertion holes 13 and the filling of resin 15 into each of the magnet insertion holes 13 are performed in a manner that cancels out a problem of this imbalanced weight.
