Abstract
The manufacturing method for a rotor includes steps of: applying an adhesive to a first surface of a magnet material member that becomes a permanent magnet after magnetization, the adhesive being applied such that a total thickness of the magnet material member and the adhesive is less than a radial width of a magnet insertion aperture; disposing a rotor core such that an axial direction thereof is horizontal, and inserting the magnet material member into a magnet insertion aperture that is positioned vertically uppermost among the magnet insertion apertures so as to orient the adhesive vertically upward; positioning each of the magnet material members by pressing the magnet material member against an inner wall surface on an outer circumferential side of the magnet insertion aperture after inserting the magnet material member into each of the magnet insertion apertures; and curing the adhesive after the magnet material member is positioned.
