Because external tooth gear 6 has identical ratio of revolutions with external tooth gear 7,, synthesizes the rotating torques of the two poles of the earth inner magnet rotor 1 and the two poles of the earth Magnmet rotor 1A, 1B, 1C, 1D generation so can not changing revolution ground.
As an example, under the state that the two poles of the earth inner magnet rotor 1 rotates with 5000 circle/per minutes individually, as shown in figure 19, connect the two poles of the earth Magnmet rotor 1A, 1B, 1C, 1D by gear, with same number of revolutions torque is synthesized, amplify thereby obtain torque.
Figure 21～22 have shown an example of the planetary gear generator of a second aspect of the present invention, represent its front view and its longitudinal section end view respectively.Shown in Figure 21～22, this planetary gear generator comprises: planetary gears, its central gear 6 be as fixed gear, and have and fixed gear planet gear meshed 7, and planetary gear 7 is arranged on the planetary gear carrier 10; Armature is arranged on the planetary gear carrier 10, and comprises seamless annular core 2 and the coil 3 that twines in the same way on full week at annular core; The two poles of the earth inner magnet rotor 1, relative with armature and be provided with, and be wholely set by planetary gear axostylus axostyle 9 and planetary gear 7, the two poles of the earth inner magnet rotor has bar magnet magnetic field vertical with its rotating shaft or tabular magnetic field of magnets, week has the gap in the rotating diameter of its leading pole tip and the described annular core 2.Be provided with a planetary gear 7 as an example in the present embodiment, but planetary gear can be provided with more than one also.
By rotating shaft 15 rotations that make planetary gear carrier 10 from the outside, make the loop coil 3 that is wholely set on planetary gear carrier 10 shown in Figure 21 utilize the rotation of the two poles of the earth inner magnet rotor 1 to produce induced electromotive force.
When the rotating shaft 15 that makes planetary gear carrier 10 turns clockwise to the right, axostylus axostyle 9 by planetary gear 7 transmits the torque that planetary gear 7 is revolved round the sun to the right, planetary gear 7 and the two poles of the earth inner magnet rotor 1 carry out revolution to the right in the rotation of carrying out right rotation.
