PURPOSE: A division core type motor is provided to improve the motor efficiency by reducing the magnetic resistance by applying a double rotor/double stator type motor. CONSTITUTION: A stator(10) comprises a plurality of division core assembly in which a first coil(12) and a second coil(14) are wound. A rotor(20) comprises a rotor supporter(40) which is fixed to a rotary shaft(48), an outer rotor(26), and an inner rotor(30). The rotor supporter is integrally formed with outer rotor and the inner rotor by an insert molding. The outer rotor comprises a first magnet(22) and a first back yoke(24). The inner rotor comprises a second back yoke(34) which is fixed to the outer side surface of a second rotor supporting unit(46) and a plurality of second magnet(32). |
