Method for manufacturing magnetic modulator, magnetic modulator, and magnetic modulation gear

Abstract

A method for manufacturing a magnetic modulator that includes a magnetic pole piece member having a plurality of magnetic pole pieces arranged in a circumferential direction and a connection portion connecting adjacent magnetic pole pieces to each other in the circumferential direction, and a shaft member, the method including: a first process of manufacturing the magnetic pole piece member by axially laminating electromagnetic steel sheets each having the plurality of magnetic pole pieces and the connection portions; a second process of performing resin molding to integrate the magnetic pole piece member and the shaft member with resin; and a third process of performing removal processing on at least one of an inner peripheral surface and an outer peripheral surface of the magnetic pole piece member.
