PURPOSE:To obtain a high-powered torque with a low electric power by dividing magnetic poles generating magnetic repulsion and attraction of a closed magnetic circuit into sets of many such poles. CONSTITUTION:A stator side of this motor has fixed field poles 1 and field-pole exciting coils 6 provided in field-pole exciting coil windows 7. A rotor side thereof has permanent magnets 4 having rotor poles 2, 3, rotor magneto coils 5, rotor covers 8, a rotor pole frame 9, a cooling fan mounting frame 10, frame arms 11, mainshaft mounting holes 12 and a main shaft hole 13. Field exciting coils 6 are respectively connected in parallel with each other for one to six phase and an electric current is applied for each phase to perform rotation, control and excitation.
