Abstract
A rotor manufacturing method for manufacturing a rotor of a rotary electric machine by disposing magnets in hole portions of a rotor core formed of stacked steel sheets, and injecting and curing a thermosetting resin to fix the magnets to the rotor core includes a temperature increasing step for increasing a temperature of the rotor core to a curing start temperature or higher, a resin injection step for causing a resin injection apparatus to inject the liquid resin at a melting start temperature or higher into the hole portions of the rotor core at the curing start temperature or higher, and a magnet fixing step for curing the resin by keeping the rotor core at the curing start temperature or higher.
