Title:
MAGNETIZATION METHOD AND MAGNET
Document Type and Number:
WIPO Patent Application WO/2008/075513
Kind Code:
A1
Abstract:
Provided is a magnetization method for a magnet to magnetize three or more poles
on one side of a magnet material by arranging a plurality of magnetizing coils.
At least one of a volume of a magnetization portion at both ends of the magnet material,
arrangement of the opposing magnetizing coils, and its setting condition is
set to be different from the other magnetization portion so that the magnetic
flux density at the magnetization portions at both ends after the magnetization
has the peak value identical to the other magnetization portion. According to
the magnet and the magnet magnetization method, it is possible to align the peak
values of the respective magnetic flux densities and align the distance between
the position where the each magnetic flux density is at its peak and the position
where each magnetic flux density is zero to be a constant value.
