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