PLANE COIL, AND NON-CONTACT POWER TRANSMISSION DEVICE USING THE SAME |
| 摘要 |
<p>This invention has an object to a planar coil, a contactless electric power transmission device using the same. This planar coil is configured to suppress an eddy current developed between adjacent turns of wire for minimizing adverse effects on ambient electrical appliances resulting from heat generation. The planar coil 1 in the present invention is formed of spiral shaped wire 7 coated with thinned insulative film, in which adjacent turns of the wire 7 are spaced in radial direction at such a predetermined interval to suppress an eddy current. This planar coil 1 its preferably employed as a power transmission coil or power receiving coil.</p> |
