Utilizing magnetic energy by crankshaft and link rod

The present invention relates to new technology of utilizing magnet energy. It the new magnetic energy utilizing method based on magnetic force balance principle and principle that similar magnetic poles expelling each other two same permanent magnets are arranged with the similar magnetic poles near each other and one iron sheet inserted in between. The permanent magnets are controlled by crankshaft and link rod in the nearest balance distance without contact, and the iron sheet is drawn out and inserted in alternately to make magnets move and to produce motive power. The method may be used in magnetic power machine, and has the advantages of saving material and increasing force.
