PROBLEM TO BE SOLVED: To provide a rotor lamination core in which a permanent magnet that is inserted into a magnet insertion hole and sealed by a resin, is disposed at one side of the magnet insertion hole in a radial direction, and a manufacturing method thereof.SOLUTION: A rotor lamination core 10 and the manufacturing method thereof are disclosed. In the rotor lamination core 10, a permanent magnet 12 is fixed eccentrically to one sides of a plurality of magnet insertion holes 11 and 11a of the rotor lamination core 10 in the radial direction (namely, to the radially outside or the radially inside). The rotor lamination core 10 includes: an adhesive 29 which is applied to one sides of the magnet insertion holes 11 and 11a in the radial direction for temporarily fixing the permanent magnet 12 at the one sides of the magnet insertion holes 11 and 11a in the radial direction; and the resin with which the other sides of the magnet insertion holes 11 and 11a in the radial direction are filled for finally fixing the permanent magnet 12. |
