A rotor of a motor and a magnet thereof are provided to improve torque output by having the magnet to interact with a stator more efficiently. A magnet(324') of a rotor includes a round part(324a). The magnets interact with a stator and are continuously arranged on an inner circumference of a york of the rotor. The shape of a side surface is rounded along a lengthwise direction on the magnet. The side surface interacts with the side of the stator directly and magnetically interacts by facing the stator. The magnet generates a strong torque output by increasing a surface area to interact with the stator under stronger magnetic interaction. |
