  • METHOD FOR MANUFACTURING ROTOR CORE
    Publication number: 20230318415
    Abstract: This method for manufacturing a rotor core includes an injection step of injecting a molten resin material into a magnet housing portion of a laminated core heated to a third temperature by a preheating step. The injection step is a step of injecting the resin material into the magnet housing portion while releasing to the outside of the magnet housing portion a volatile organic compound volatilized by heating the resin material by bringing the resin material into contact with the laminated core heated to the third temperature.
