Rotor manufacturing method

摘要

A rotor manufacturing apparatus includes a pusher and multiple blades. The pusher presses multiple magnets that are temporarily attached to a rotor core and arranged side by side in a circumferential direction of the rotor core from an outer side in a radial direction of the rotor core. The multiple blades are individually inserted into gaps between the magnets pressed by the pusher.

1. A permanent-magnet positioning method comprising:
a pressing step of pressing a plurality of permanent magnets temporarily attached to a rotor core and arranged side by side in a circumferential direction of the rotor core from an outer side in a radial direction of the rotor core; and a positioning step of positioning the permanent magnets in the circumferential direction by individually inserting a plurality of blade portions into gaps between the permanent magnets that have been pressed since the pressing step so that each of the permanent magnets contacting a first one of the blade portions is moved in the circumferential direction and thus pressed against a second one of the blade portions that is adjacent to the first one of the blade portions.
