Manufacturing Device and Manufacturing Method for Magnet Embedded Core

A manufacturing device for a magnet embedded core in which a magnet is inserted in a magnet insertion hole which is formed in a rotor core to extend along an axial direction and to have both ends open, the magnet being fixed to the rotor core with resin, wherein:

• the magnet includes at least two outer surfaces facing in mutually opposite directions and two end surfaces provided on respective side ends of the two outer surfaces, and
• the magnet insertion hole includes two inner surfaces having a spacing dimension larger than a spacing dimension of the two outer surfaces of the magnet so as to oppose the respective outer surfaces of the magnet,
• the manufacturing device comprising:
• a first plate and a second plate configured to contact against two end surfaces of the rotor core, respectively;
• and
• restriction members provided on at least one of the first plate and the second plate,
• wherein the restriction members are capable of entering the magnet insertion hole and provided at positions opposing the respective end surfaces of the magnet to allow movement of the magnet in a first direction, which is a separation direction of the two inner surfaces of the magnet insertion hole, and to restrict movement of the magnet in a second direction orthogonal to the first direction as viewed in the axial direction of the magnet insertion hole.
