Contact generator with light emitting wheel for use with a roller skate has permanent magnet assembly and bearings are inserted around the bearing spacer inserted around the wheel axle

摘要

The contact generator comprises permanent magnet assembly (128,130) and bearings (126) inserted around a bearing spacer (134) inserted around a wheel axle (122). Buffer wings (132) are formed on the surface of the buffer absorbing the impacts to the permanent magnet. An armature coil spool (142) has an armature coil (144) formed at the armature coil assembly (140). Current is induced to the armature coil in the spool due to electromagnetic induction.
