ROTOR HAVING RESIN HOLES FOR FILLING RESIN AND METHOD OF PRODUCING A ROTOR

摘要

A rotor which can raise the axial direction strength near the end edges outside of the rotor core in the radial direction. The rotor comprises a shaft, a rotor core which has a plurality of magnetic steel sheets and is fastened to the shaft, and a plurality of magnets which are arranged inside of the rotor core. The rotor core has a center hole which holds the shaft, a plurality of magnet holes which are arranged at the outside of the center hole in the radial direction and hold magnets, resin holes which are arranged at the outsides of the magnet holes in the radial direction and which run through the rotor core in the axial direction, and rotor core fastening members which include first resin parts which are filled inside the resin holes.
