Title:
MAGNETIZATION DEVICE AND MAGNETIZATION METHOD OF MAGNETIC ENCODER
Document Type and Number:
Japanese Patent JP2017168707
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a magnetization device and a magnetization method for magnetic encoder which allow for magnetization without affecting each other between adjoining magnetic traffics, even when magnetizing double rows of magnetic traffic on the magnetization surface of a magnetized body.SOLUTION: A magnetization device has a conductor 6 through which a magnetization current is fed, and a magnetization yoke 1 having an apical surface 4 in which a groove 5 for conductor, where a part of the conductor 6 is placed, is formed. A magnetized object 7 is placed so that a not-yet-magnetized magnetization surface 10 faces the apical surface 4 of the magnetization yoke 1. The apical surface 4 of the magnetization yoke 1 and the magnetization surface 10 of the magnetized object 7 move relatively in the arrangement direction of the N pole and S pole in a magnetic track. The conductor 6 is extending from the opposite ends of a portion placed in the groove 5 for conductor in the apical surface 4 of the magnetization yoke 1, while bending almost at right angle to the side receding from the magnetized object 7.SELECTED DRAWING: Figure 4
