DEVICE AND METHOD FOR INSERTING MAGNET INTO ROTOR CORE MAGNET INSERTION HOLE

摘要

This device for inserting a magnet into a rotor core magnet insertion hole (22) in which a plurality of magnet pieces (31) are inserted into the magnet insertion hole (22) provided in a rotor core (21) of a motor (AA) is equipped with a guide means (43) which is provided with a magnet loading opening and a magnet exit opening and which lines up the plurality of magnet pieces (31) loaded into the magnet loading opening up until the pieces exit the magnet exit opening to guide the aligned plurality of magnet pieces such that the pieces pass through the magnet exit opening and are inserted into the magnet insertion hole. The size of the magnet loading opening of the guide means (43) is larger than the size of the magnet insertion hole, and the size of the magnet exit opening is the same or smaller than the size of the magnet insertion hole (22), the shape from the magnet loading opening to partway to the magnet exit opening being a tapered shape.
