Abstract
A coil device includes a first coil portion which faces a second coil portion of another coil device and has a conductive wire, and at least one non-magnetic member disposed on an opposite side from a side facing the second coil portion. The non-magnetic member includes an eddy current interrupter for changing a state of an eddy current formed in the non-magnetic member by interrupting a portion of the eddy current.
Claims19
A coil device facing another coil device to transmit or receive power wirelessly, the coil device comprising:
- a first coil portion facing a second coil portion of the other coil device and including a conductive wire;
- and
- at least one non-magnetic member disposed on an opposite side from a side facing the second coil portion,
- wherein the non-magnetic member includes an eddy current interrupter for changing a state of an eddy current formed in the non-magnetic member by interrupting a portion of the eddy current.
An inductance-changing mechanism configured to change an inductance of a coil inside an electric circuit, the inductance-changing mechanism comprising:
- a coil support body for supporting the coil,
- wherein the coil is formed by a conductive wire extending to turn around a winding axis of the coil support body,
- the coil support body includes first and second fixing portions to which both end portions of the coil are fixed, mutual relative positions of the first and second fixing portions being changeable, or a plurality of types of fixing portions configured to fix the conductive wire, and
- a shape of the coil is changeable either due to relative positions of the first and second fixing portions being changeable, or a state being switchable between one state in which the conductive wire is fixed to any one of the plurality of types of fixing portions and another state in which the conductive wire is fixed to another of the plurality of types of fixing portions.
