PURPOSE: A motor device and a method for manufacturing the same are provided to reduce the number of components and to prevent self rotation of a core. CONSTITUTION: A motor device includes a stator(110) having a core around which a coil is wound. A rotor(120) has a magnet(122) and rotates a shaft. The magnet faces the coil so as to generate the electromagnetic force. A sleeve(130) is used for supporting the shaft. A sleeve housing includes a loading plate. The loading plate is used for supporting the core. A protrusion is formed on the loading plate so as to prevent the rotation of the core.
