Magnetic attraction driving engine using permanent magnet

摘要

A magnetic attraction driving engine utilizing a permanent magnet is provided with a permanent magnet, an electromagnet formed by winding a coil on a magnetic core with one end thereof stuck to one magnetic pole end of the permanent magnet, an excitation controller for exciting the electromagnet to change a state of magnetic fluxes in the vicinity of the magnetic pole end of the permanent magnet, a movable member having magnetic attractivity set in the vicinity of the magnetic pole end of the permanent magnet by being supported and guided so as to be capable of coming close to or separating away from the permanent magnet and a returning force applying member for causing by pressure the movable member to retreat against a magnetic attracting force and move back and forth by changing a magnetic attracting force of the permanent magnet. <IMAGE>
