METHOD FOR FORMING MAGNETIC FIELD SPACE |
摘要 |
A power-supplying resonator of a power-supplying module and a power-receiving resonator of a power-receiving module are arranged to face each other. On inner circumferential surface sides of the power-supplying resonator and the coil of the power-receiving resonator, cylindrical magnetic members which cover the entire inner circumferential surface of the coils of the power-supplying resonator and the power-receiving resonator are arranged. By conducting power transmission between the power-supplying resonator and the power-receiving resonator while varying a magnetic field, the magnetic field occurring around the power-supplying resonator and the power-receiving resonator is shielded by the magnetic members, and there is formed, on the coil inner circumferential surface sides of the power-supplying resonator and the coil of the power-receiving resonator, a magnetic field space whose magnetic field strength is smaller than the magnetic field strength of areas other than the inner circumferential surface sides. |

1. A method of forming a magnetic field space, comprising:
arranging one of coils of a power-supplying module and one of coils of a power-receiving module so as to face each other; arranging a magnetic member so as to cover at least partially surfaces of the one of the coils of a power-supplying module and the one of coils of a power-receiving module except for surfaces facing each other; conducting power transmission between the one of the coils of the power-supplying module and the one of the coils of the power-receiving module while varying a magnetic field so as to form, in a desirable location, a magnetic field space whose magnetic field strength is smaller than magnetic field strength of areas other than the desirable location. |
