Abstract

In an embedded magnet rotor for a rotary electric machine, permanent magnets are respectively accommodated in magnet housing apertures that pass axially through a rotor core that is held by a shaft, an adhesive is injected into and cured in gaps between the permanent magnets and the rotor core in the magnet housing apertures, and fixes the permanent magnets to the rotor core, a first end plate is held by the shaft so as to contact a first axial end of the rotor core, and blocks first axial end openings of the plurality of magnet housing apertures, and a fill rate of the adhesive that is injected into the gaps is increased gradually from a first axial end toward a second axial end of the magnet housing apertures.
