Abstract: The present invention relates to a rotating device using the magnetic force of a magnet. More particularly, the present invention relates to a rotating device for obtaining power by converting magnetic force energy into physical kinetic energy using the attraction force and the repulsion force of a pure magnet without using external energy, a link and a secondary stator. Generally, a rotating device using a pair of magnets has a problem that a torque is not generated because the repulsion force and the attraction force of the permanent magnet are the same and the sum of the moments is the same. Accordingly, the present invention has been suggested in consideration of problems occurring in the prior art. A rotating device is provided. Unlike the law of conservation of energy or the first law of thermodynamics due to the change of entropy or enthalpy, power can be obtained by acceleration using one-way thrust using the attraction and repulsion of a magnetic force without a change of enthalpy, a rotation link, and an auxiliary stator. An installation structure includes the installation means of a body plate, the installation means of a rotating plate, and a guide rail.

Abstract: The present invention relates to an iron plate heating machine with a tension device. The present invention fixes both sides of an iron plate, such as a fender of a car, via a clamp to which heat is transferred by a resistance heater so that heat is transferred to the iron plate. Since a central portion of the iron plate droops by self-weight when the iron plate is heated and a defective iron plate is generated, a tension device which does a vertically reciprocating action by a cylinder supports the iron plate, thereby enhancing workability by preventing defective iron plates generated due to drooping of the iron plate during heating. According to one embodiment of the present invention, the clamps for fixing the iron plate are to effectively cope with lengths of different iron plates, and to maintain tension of the iron plate by widening an interval between the clamps when drooping occurs due to heating of the iron plate, thereby preventing defective iron plates generated due to drooping by self-weight of the iron plate and enhancing workability.
