Abstract: A power feeding coil unit includes a first power feeding coil and a second power feeding coil that generate a first magnetic flux, a first auxiliary coil that generates a second magnetic flux interlinking with the first power feeding coil, and a second auxiliary coil that generates a third magnetic flux interlinking with the second power feeding coil. An axial direction of the first auxiliary coil is nonparallel to an axial direction of the first power feeding coil, and an axial direction of the second auxiliary coil is nonparallel to an axial direction of the second power feeding coil. A direction of circulation of the second and third magnetic fluxes are opposite to a direction of circulation of the first magnetic flux.

Abstract: Disclosed herein is a coil unit for wirelessly transmitting or receiving power by magnetic coupling with a first coil wound in a planar spiral shape. The coil unit includes a second coil that is wound in a planar spiral shape with a smaller wound area than that of the first coil and has an opening, and a magnetic member that is arranged along a surface of the second coil on an opposite side as viewed from the first coil. The magnetic member is constituted by a plurality of magnetic bodies being spaced from each other. Each of the magnetic bodies is arranged to overlap both a winding portion of the second coil and the opening in plan view. A distance between two adjacent magnetic bodies among the magnetic bodies is 3% or more and 30% or less of a maximum width of the second coil.

Abstract: A rotating electrical machine includes a stator, a rotor with a permanent magnet, a first number of one or more first coils, and a second number of one or more second coils. The second number is different from the first number. The one or more first coils are disposed on the stator. The one or more second coils are disposed on the rotor. The one or more first coils and the one or more second coils are disposed on the stator and the rotor, respectively, in such a manner as to closely oppose each other in a state where the rotor is at a predetermined rotation angle position. The one or more first coils are arranged to induce a voltage in response to a relative position with respect to the one or more second coils.
