Abstract: The present invention relates to an automatic rotating device using magnets and electromagnets and, more specifically, to a device that has a rotor and a stator each having both a magnet and an electromagnet and generates rotational force by using the power of the electromagnets using self-generated electricity. In general, a motor is a rotating device for converting electrical energy into mechanical energy and is divided into a direct current motor driven by direct current power and an alternating current motor driven by alternating current power. The motor is divided into brush- and brushless-type direct current motors according to electricity supply methods. The brush-type direct current motor has a structure with a brush that contacts a rotor to supply a current to a coil wound around an iron core, and is a device that is rotated when electric energy is supplied thereto from the outside. The automatic rotating device has a small electromagnet installed outside of a shielding means to change the direction of the reverse rotational force of attractive and repulsive force generated at the portion where the magnetic poles intersect each other, generating electricity with the force. The automatic rotating device creates an electromagnet with the self-generated energy to use the attractive and repulsive force of the electromagnet as a rotational force. The automatic rotating device is a clean energy device which includes the power of the magnets in the rotational force of the electromagnet so that stronger natural energy is generated as the rotational force. Therefore, the invention is positively necessary.
