MANUFACTURING METHOD OF ROTOR AND ROTOR

摘要

In a method for manufacturing a rotor, each magnetic steel sheet (11) has protrusions (111) on its one surface (11f) and has recesses (112) on the other surface (11g) at positions corresponding to the protrusions (111). The plurality of magnetic steel sheets (11) are joined together as the protrusions (111) of each magnetic steel sheet (11) are fitted in the recesses (112) of its adjoining magnetic steel sheet. A shaft member (20) is inserted into a rotor core (10) in the same direction as that in which the protrusions (111) protrude.
