A motor is provided to prevent magnetic loss by correcting the eccentricity of the rotor without the height change of a core. A first bearing(121) is fixed in one side of a housing(110). A second bearing(125) is fixed in the other side of the housing. One side of a rotation axis(130) is supported in the first bearing. The other side of the rotation axis is exposed to the outer circumference of the other side of the housing. The central part of the rotation axis is supported in the second bearing. The core(150) is fixed in the outer circumference of the rotation axis between the first bearing and the second bearing. A plurality of teeth(153) are formed in the core with a predetermined interval. An insulating member(180) is combined in one side and the other side of the core. The insulating member surrounds the plurality of teeth. The coil(160) is wound around the insulating member along the longitudinal direction of the rotation axis. A magnet(170) is fixed in the housing. The magnet rotates the coil, the core, and the rotation axis by the interaction with the coil.
