Title:
磁気エンコーダ等の多極磁化環状体の着磁方法および着磁装置
Document Type and Number:
Japanese Patent JP5275840
Kind Code:
B2
Abstract:
A magnetic encoder magnetizing method, in which magnetization of the plural neighboring tracks of the magnetic encoder can be accurately performed, is provided. While an annular magnetic body having a plurality of annular, unmagnetized magnetic encoder tracks integral therewith and juxtaposed relative to each other is rotated, the tracks of the magnetic encoder are individually magnetized by a magnetizing head, made up of a magnetizing yoke and an exciting coil, to thereby provide the magnetic encoder. In the practice of this magnetizing method, when one of the tracks of the magnetic encoder is magnetized, the other track is covered with a magnetic shielding mask.
