DISC DRIVING MOTOR

摘要

PURPOSE: A disc driving motor is provided to enhance the assembly work efficiency with the reduction of the number of assembly work processes by incorporating a disc-seating unit with a rotor. CONSTITUTION: A rotor(200) is provided with a case(210) on which a magnet(211) is attached. A disc-seating unit(300) is provided on the case(210) in one body. A rotation shaft(100) is inserted into the center of the disc-seating unit(300). A boss(310) having a through hole(311) is provided on the center portion of the disc-seating unit(300). A stator(400) generates a rotation force through the interaction with the rotor(200). A stator core(420) is provided on the stator(400) and the stator core(420) has a coil for generating an electromagnetic force together with a magnet(211) of the rotor(200).
