Method of manufacturing rotor in which magnet is inserted into magnet hole of rotor core

A method of manufacturing a rotor in which a magnet is inserted into a magnet hole of a rotor core, the method comprising:

• inserting an insertion member into the magnet hole having a first opening and a second opening;
• fixing the magnet to the insertion member extending out from the second opening;
• inserting the magnet, which is fixed to the insertion member, into the magnet hole from the second opening by pulling the insertion member extending out from the first opening in a direction separating away from the rotor core;
• and
• cutting the insertion member extending out from the first opening,
• wherein a central axis direction of the magnet hole is angled with respect to a vertical direction,
• the magnet hole includes two inner wall surfaces facing each other, one of which is a lower inner wall surface located on a lower side along the vertical direction,
• the inserting of the magnet is executed in a state of having a lower surface of the magnet in contact with the lower inner wall surface via the insertion member,
• the magnet has a shape of a substantially rectangular solid,
• the magnet includes the lower surface, an upper surface being a surface opposite to the lower surface, and a first side surface and a second side surface that are orthogonal to a central axis of the magnet hole,
• wherein a distance between the first side surface and the magnet hole is greater than a distance between the second side surface and the magnet hole, and
• in the fixing, the insertion member is fixed to the magnet so as to cover the upper surface, the first side surface, and the lower surface of the magnet.
