Original Abstract Submitted
A manufacturing apparatus of a rotor is for a rotor having a permanent magnet provided in a state of being embedded inside a rotor core, the permanent magnet having a folding shape being convex towards a radially inside part. The manufacturing apparatus includes a magnetization apparatus that magnetizes the permanent magnet in the embedded state from outside the rotor. The magnetization apparatus is provided with a yoke part at least disposed in an axially outside part of the rotor, the yoke part constituting a magnetic path for supplying a magnetization flux to the permanent magnet. The yoke part includes at least one of a dust core, a laminated steel plate, and a slit having a function of suppressing eddy current occurring due to the magnetization flux.
