  • Rotating body non-contact power-feeding device and torque sensor
    Patent number: 9958345
    Abstract: A rotating body non-contact power-feeding device comprises: a power receiving-side substrate with a power receiving-side circuit component mounted thereat, which is fixed to a rotating shaft supported via a bearing and rotates as one with the rotating shaft; and a power transmitting-side substrate with a power transmitting-side circuit component mounted thereat, which is fixed to a holding unit holding the bearing so that a substrate surface thereof faces opposite a substrate surface of the power receiving-side substrate and is connected with a power source, wherein: a power transmitting-side coil is formed with a conductive pattern so as to achieve a flat-plane spiral pattern with a plurality of turns at a substrate surface facing opposite the power receiving-side substrate and the power transmitting-side circuit component is mounted at another substrate surface, at the power transmitting-side substrate that includes a substrate front surface and a substrate back surface, a power receiving-side coil is forme

  • Non-contact power feeding device used in torque sensor having a coil enclosed in peripheral side of a resonance coil and is magnetically coupled with the resonance coil
    Patent number: 9960641
    Abstract: A non-contact power-feeding device comprises: a power transmitting unit that includes a first antenna coil, an oscillator and a driver that enables generation of an AC magnetic field via the first antenna coil based upon a signal provided by the oscillator; and a power receiving unit that includes a second antenna coil that is magnetically coupled with the first antenna coil, wherein the first antenna coil comprises: a flat-plane spiral resonance coil wound with a plurality of turns; and a flat-plane spiral power-feeding coil that is wound with a plurality of turns outward relative to the resonance coil so as to surround the resonance coil, and is magnetically coupled with the resonance coil.
