A resin injection apparatus configured to manufacture a rotor of a rotary electric machine includes a resin injector having an ejection port for ejecting a resin, and a runner having a charging port connectable to the ejection port, and a plurality of ejection ports communicating with the charging port and disposed at positions associated with hole portions of a rotor core where magnets are disposed.

Rotor manufacturing apparatus and rotor manufacturing method

A method of manufacturing a rotor that includes a rotor core and a permanent magnet fixed to the rotor core using an adhesive, the method includes applying the adhesive, which contains a volatile agent, to an adhesive placement position of the permanent magnet; drying the adhesive by volatilizing the volatile agent by a magnet heater directly heating the permanent magnet such that a temperature of the permanent magnet becomes higher than a temperature of the adhesive after applying the adhesive; placing the permanent magnet on the rotor core after drying the adhesive; and fixing the permanent magnet to the rotor core by curing the adhesive after placing the permanent magnet.

Rotor manufacturing method

A method of manufacturing a rotor including a rotor core and a permanent magnet that is bonded to the rotor core with an adhesive containing a foaming agent, wherein applying the adhesive includes applying the adhesive such that the adhesive is spread to a portion on a front side with respect to the application area on the application surface, by moving the nozzle to a front side in the nozzle traveling direction with respect to a position in the application area at which feeding of the adhesive by the pump is finished.

Method of manufacturing rotor

A method for manufacturing a rotor including a rotor core and a permanent magnet, the rotor core having a magnet hole, and the permanent magnet being inserted in the magnet hole and fixed to the rotor core with an adhesive, including the steps of: applying the adhesive, inserting the permanent magnet into the magnet hole of the rotor core, volatilizing the diluting solvent, expanding the expanding agent, and fixing the permanent magnet to the rotor core.
