In a method for manufacturing an interior permanent magnet rotor unit, a radial magnetizing part 30 including high magnetic permeability portions 32 and low magnetic permeability portions 34 face a core 22, and a magnetic field of axial magnetizing parts 40 and 50 is applied to the radial magnetizing part 30 in an axial direction Da of the radial magnetizing part 30. This causes the magnetic field to enter the core 22 via the radial magnetizing part 30 and cross magnet materials filling insertion holes 24 of the core 22. |
