PURPOSE: A duplex magnetic force motor is provided to improve efficiency of a motor by continuously forming a strong magnetic field and separately arranging an external stator permanent magnet at an external side of a housing from an internal stator permanent magnet. CONSTITUTION: An internal stator permanent magnet(20) is fixed to an inner side of a housing(10). A magnetic force exposure window(11) is formed in a location where corresponds to the internal stator permanent magnet. An external stator permanent magnet(40) is arranged in the location where corresponds to the internal stator permanent magnet at the outside of the magnetic force exposure window. The external stator permanent magnet is fixed while being separated from the magnetic force exposure window by a distance piece(41). An insulation board is installed between the magnetic force exposure window and the external stator permanent magnet.
