Abstract:
A rotor includes: a rotor core fixedly attached to a rotational shaft and having a magnet-inserted hole portion; a magnet inserted into the magnet-inserted hole portion; and a resin portion injected into the magnet-inserted hole portion. The rotor core is constructed by axially stacking a plurality of electromagnetic steel sheets. The electromagnetic steel sheets include: an electromagnetic steel sheet having the magnet-inserted hole portion and a weight-reducing-purpose hole portion provided separately from the magnet-inserted hole portion; and an electromagnetic steel sheet located on at least one axial end of the rotor core and having a portion covering the hole portion formed in the electromagnetic steel sheet.
