| 简介 |
PURPOSE : An improved magnet assembly for a light-emitting wheel is provided to enable a user to assemble by a simple process, not to be deformed in spite of tightening an axle by a strong power, and to maintain magnetic force while reducing volume of the rare-earth magnet.
CONSTITUTION : The improved magnet assembly for a light-emitting wheel includes a permanent magnet(300) made of rare earth in a ring shape with high magnetic force and wrapping a wheel axle, and a spacer connected to the permanent magnet in the ring-shaped permanent magnet, playing a bearing spacer role, and made of ferrite compound material. The spacer and the permanent magnet are separately manufactured and connected after the spacer is put into the permanent magnet.
