ELECTROMAGNETIC GENERATOR, MOUNTING METHOD OF ELECTROMAGNETIC GENERATOR AND TIRE WITH BUILT-IN ELECTROMAGNETIC GENERATOR

摘要

When an electromagnetic generator 10 having a pendulum structure is mounted on an interior surface of a tire 20, an equivalent pendulum length l of a pendulum 14 is adjusted such that an integral multiple of a period », of the pendulum 14, which is determined by the equivalent pendulum length l of the electromagnetic generator 10, is not in agreement with both of an integral multiple of a circumferential length L of the tire 20 and a length S of a non-grounded part of the tire, which is obtained by subtracting a ground contact length C from the circumferential length L of the tire 20, whereby the power generation capacity of the electromagnetic generator mounted on the tire can be improved regardless of the type of the tire.
