<p><P>PROBLEM TO BE SOLVED: To simplify the structure for feeding power to a coil in a motor, and to reduce an energy loss by reducing leakage flux. <P>SOLUTION: An armature-side stator 13 equipped with an armature coil 24, a pair of a first rotor 12 and a second rotor 14 equipped with inductors 20, 21, 27 and 28 arranged on both sides of the armature-side stator 13, and the pair of the first field side stator 11 and the second field side stator 15 arranged on the other side of the first rotor 12 and the second rotor 14, respectively, are arranged through an air gap in the axial direction of a drive shaft 34 on which the first and second rotors 12 and 14 are arranged. In such an axial motor, first and second field coils 18 and 31 are arranged annularly around the axis of the drive shaft 34 on the first and second field side stators 11 and 15, respectively. Currents are conducted reversely through these first and second field coils 18 and 31 so that magnetic flux is generated reversely in the first and second field coils 18 and 31. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
