Abstract

The manufacturing method of a motor core includes attaching an ID code to a stack of blanked members in which a magnet insertion hole to fill with a resin material is formed, the ID code containing information in accordance with a type of the stack, reading the information from the ID code which is attached to the stack, and setting a mold condition based on the information read from the ID code. The mold condition includes at least one type of condition including: the resin material to be injected to the magnet insertion hole, an injection amount of the resin material, and a discharge position of the resin material. A mold device is controlled to inject the resin material to the magnet insertion hole in accordance with the mold condition.
