Abstract

See full text

A rotor is located around an outer periphery of a rotation shaft of a motor and rotates together with the rotation shaft. The rotor includes magnetic steel plates laminated in an axial direction and including a through-hole group passing therethrough in the axial direction. The through-hole group includes through-holes each including, as a central line, an imaginary line extending in the radial direction and having an arcuate shape extending from the central line to both sides and radially outward. The through-holes are arranged in the radial direction. Among the through-holes, a radius of curvature of an arcuate radially inner side surface of the radially innermost through-hole is the smallest, and/or a radius of curvature of an arcuate radially outer side surface of the radially outermost through-hole is the largest.
