A BLDC motor and a rotator for the same are provided to have no separate current control required for rotating a rotator, increasing torque, and reducing vibration and noise, and to reduce material costs. A BLDC motor comprises a stator, a plurality of teeths, a rotor(2), a plurality of magnets, barriers(71,72,73), and a chamferring part(81). A plurality of teeths is wound at the inner side of a stator. The stator is spaced from the inner side of the stator. A plurality of magnets is inserted into the edge portion of the rotor. The barrier is formed by extending a magnet insertion part(6) in at least one side direction. The chamferring part is formed in the circumference of the rotor to become deep at a q axis of a rotating coordinate system which passes the interval of the magnet which is adjacent among a plurality of magnets. |
