A variable ratio transmission includes a rotor having a first set of coils, a second rotor having a first set of iron segments, a third rotor having second and third sets of coils, and a second set of coils. A fourth rotor having an iron segment and a fifth rotor having a fourth set of coils. The first set of coils is magnetically connected to the first set of iron segments. The first set of iron segments is magnetically connected to the second set of coils. The first, second and third rotors form a first set of magnetic gears. A third set of coils on the third rotor is magnetically connected to a second set of iron segments on the fourth rotor. The second set of iron segments is magnetically connected to the fourth set of coils. The third, fourth and fifth rotors form a second set of magnetic gears that are coupled to the first set of magnetic gears. [Selection] Figure 1a |
