PURPOSE: A generator generating electricity with rotating a field magnet is provided to receive a strong magnetic force from stators respectively formed with multiple permanent magnets at both sides of a rotor, thereby improving electricity generation efficiency with a structure for easily generating an electromotive force. CONSTITUTION: A generator generating electricity with rotating a field magnet includes a rotor(10), a rotating unit(20), a first stator(30), a second stator(40), a fixed frame(50), a rectifier(60), and a transmitting unit(70). The rotor comprises multiple field magnets(11) separated one another at equiangular distances. The rotating unit receives power outside, and rotates the rotor. The first stator comprises multiple first permanent magnets(31) separated one another at equiangular distances. The first permanent magnets are separated outside the rotor, and magnetic poles thereof are sequentially alternate one another. The second stator comprises multiple second permanent magnets(41) separated one another at equiangular distances. The second permanent magnets are separated inside the rotor, and magnetic poles thereof are sequentially alternate one another. The first and the second magnetic magnets face each other, and the magnetic poles thereof are mutually placed to be opposite. An annular groove(51) is formed inside the fixed frame having the first and the second stator. The rectifier is respectively connected with coils(11b), converts the electricity generated from the rotor into a direct current, and supplies the direct current. The transmitting unit is electrically connected to the rectifier, and transmits the electricity generated from the rotor to the outside. |
