ROTOR MANUFACTURING METHOD

摘要

In a rotor manufacturing method, a magnetic body is moved by being pushed by a pusher along a guide surface of a guide portion, and the magnetic body is in a stated of being biased to the guide surface since the magnetic body is urged by a restriction portion. Therefore, the magnetic body can slide reliably between the guide portion and the restriction portion while restricting an insertion posture of the magnetic body. Thus, even if a wall surface of a magnet insertion hole is provided with a protrusion, when the magnetic body slides with the guide surface as a reference, the magnetic body will not abut against the protrusion, and the magnetic body can be reliably loaded into the magnet insertion hole.

1. A rotor manufacturing method, wherein the rotor comprises: a stacked body provided with a magnet insertion hole extending in a direction of a rotation axis, and formed by stacking laminated steel plates in an extending direction of the rotation axis; a protrusion protruding from a wall surface which forms the magnet insertion hole; and a bar-shaped magnetic body arranged in the magnet insertion hole, the rotor manufacturing method comprising:
loading the magnetic body into the magnet insertion hole by pushing the magnetic body on a guide surface towards the magnet insertion hole while an posture of the magnetic body is restricted by the guide surface and a restriction portion, wherein the guide surface is arranged on a magnet insertion device provided at a magnet insertion inlet side of the magnet insertion hole and is in contact with one side surface of the bar-shaped magnetic body, and the restriction portion restricts the posture of the magnetic body.
