Power supply arrangement for body fitness machine

Abstract

A power supply arrangement for body fitness machine is disclosed to include permanent magnets mounted on the flywheel of the body fitness machine, a rack mounted on the base frame of the body fitness machine to hold a stack of silicon steel plates, and windings mounted on the rack to act with the permanent magnets for inducing electric current for the working of the lighting circuit of the instrument panel of the body fitness machine.

1 . A power supply arrangement installed in a body fitness machine having a flywheel pivotally mounted on a base frame and a driving wheel for pedaling by the user to rotate said flywheel, and adapted to generate electricity for a lighting circuit of an instrument panel of said body fitness machine, the power generating device comprising:
 a plurality of magnet holders fixedly mounted on said flywheel;   a plurality of permanent magnets fixedly mounted in said magnet holders;   a rack fixedly mounted on the base frame of said body fitness machine;   a stack of silicon steel plates mounted on said rack; and   a plurality of windings mounted on said silicon steel plates for acting with said permanent magnets to induce electric current upon rotation of said flywheel.
