    摘要: The present invention has an object to propose a method of producing a rotor, capable of reliably fixing a magnet to a rotor core with resin and preventing breakage of the rotor core. The present invention includes a step of fixing a permanent magnet to a rotor core by injecting molten resin into a slot by injection molding on the condition that, assuming that: a dimension between an end surface of the rotor core and an end surface of the permanent magnet is a core end surface-magnet interval; and a minimum value of a dimension between an inner surface of the slot and a side surface of the permanent magnet, allowing the molten resin to fully fill a clearance between the inner surface of the slot and the side surface of the permanent magnet by injecting the resin into the slot through a cylinder, is a minimum slot-magnet interval value, and a value of the core end surface-magnet interval is equal to or larger than the minimum slot-magnet interval value.

A lower surface of a rotor core is arranged in a lower mold. A magnet is arranged in a lower mold. A magnet is contained in each of magnet containing holes formed in the rotor core in such a manner that a predetermined space is assumed between an upper surface of the rotor core and an upper surface of the magnet. An upper mold is arranged on the upper surface of the rotor core. The upper mold and the lower mold apply a pressure to the rotor core and a molten resin is supplied with pressure from an internal diameter side via the predetermined space into the plurality of magnet containing holes from respective cylinder arranged in the upper mold. Thus, the magnets are molded by resin while pressing the magnets toward the outer diameter side of the magnet containing holes.
