<p>The present invention relates to an electric device. Regarding the use, the present invention relates to the electric device which can be used as a generator or a motor. An embodiment of the electric device of the present invention comprises a shaft which is installed to be able to rotate; and a rotor which can be rotated to be combined to the shaft. A plurality of permanent magnets is arranged on a first area of a disk as a first permanent magnet arrangement along a circumferential direction and a plurality of permanent magnets is arranged on a second area which is opposite side of the first area as a second permanent magnet arrangement along the circumferential direction. Regarding the rotor, one of the first and second permanent magnet arrangements is tilted with a predetermined angle along the circumferential direction of the shaft for the other one based on the arrangement location of a shaft rotary shaft direction of an N or S pole permanent magnet arranged on the first area and an N or S pole permanent magnet arranged on the second area. The electric device comprises first and second stators which are on opposite sides of the rotor and have a plurality of slots in which a coil is wired.</p> |
