Abstract
A rotor manufacturing method is a method that allows magnetized magnets inserted in second magnet holes of a second rotor core to be inserted, while retaining magnetism, into first magnet holes of a first rotor core. This method includes a placing step of placing the second rotor core on a first end surface, in a stack thickness direction, of the first rotor core such that the second magnet holes overlap the first magnet holes, and an extruding step of extruding the magnetized magnets from the second magnet holes toward the first magnet holes using a non-magnetic jig.
