    Abstract: A coil substrate includes a flexible substrate having first and second ends, a first coil formed on first surface of the substrate such that the first coil has center space and first wiring surrounding the space, and an second coil formed on second surface of the substrate such that the second coil has center space and second wiring surrounding the space and is positioned directly below the first coil. Each of the first and second wirings has outer and inner ends such that each wiring is formed in spiral shape between the outer and inner ends, a number of turns in the first coil is greater than a number of turns in the second coil, a width of the first wiring is substantially constant from the outer end to the inner end, and a width of the second wiring is not constant from the outer end to the inner end.

    IPC: H02K3/26

    Abstract: A coil substrate includes a flexible substrate having a first end and a second end on the opposite side with respect to the first end, and coils formed on the flexible substrate in substantially one row between the first end and the second end of the flexible substrate such that each of the coils has a center space and wirings surrounding the center space. The wirings in each of the coils include parallel wirings formed substantially parallel to a row direction extending from the first end toward the second end and perpendicular wirings formed substantially perpendicular to the row direction, and the coils are formed such that a thickness of the perpendicular wirings is greater than a thickness of the parallel wirings.

    Abstract: A motor coil substrate includes a coil substrate that is wound in a cylindrical shape and includes a flexible substrate and coils formed on the flexible substrate such that the flexible substrate has a first end and a second end on an opposite side with respect to the first end and that the coils are arrayed from the first end to the second end of the flexible substrate. The coils are formed such that each of the coils has a central space and includes wirings surrounding the central space, and the flexible substrate has openings formed such that each of the openings is penetrating through the flexible substrate and positioned in the central space of a respective one of the coils.

    Abstract: A coil substrate includes a flexible substrate, and coils formed on the flexible substrate such that the coils are positioned substantially in a raw and that each coil has a center space and wirings surrounding the center space. The coils are formed such that each coil includes first wirings on a first surface of the flexible substrate, second wirings on a second surface of the flexible substrate on the opposite side with respect to the first surface, and via conductors penetrating through the flexible substrate and connecting the first and second wirings, and the coils are positioned such that a m-th coil has the second wirings positioned below the center space of a (m+1)-th coil and that a (m+2)-th coil has the first coils positioned on the center space of a (m+1)-th coil, where in is an integer equal to or greater than 1.
