Title:
PERMANENT MAGNET MAGNETIZATION DEVICE AND PERMANENT MAGNET MAGNETIZATION METHOD
Document Type and Number:
WIPO Patent Application WO/2006/098410
Kind Code:
A1
Abstract:
[PROBLEMS] To effectively and rapidly perform intensive magnetization work at a low cost while enhancing the magnetization quality without causing insufficient magnetization even in a case of a ring-shaped permanent magnet having a narrow magnetization pitch such as minute diameter and multiple poles. [MEANS FOR SOLVING PROBLEMS] A permanent magnet magnetization device includes a heating unit (10), a magnetization unit (12) arranged in the axial direction separately from the heating unit (10), and a holding member (22) of an object-to-be-magnetized (20) which can be relatively shifted with respect to the heating unit and the magnetization unit. The object-to-be-magnetized heated by the heating unit is transferred to the magnetization unit so as to be magnetized.
