Abstract: A motor coil substrate includes a flexible insulating substrate having a cylindrical shape, wirings formed on a first surface of the flexible insulating substrate and a second surface of the flexible insulating substrate on the opposite side with respect to the first surface, and via conductors including copper plating penetrating through the flexible insulating substrate such that the via conductors are connecting the wirings formed on the first surface and the wirings formed on the second surface. The wirings and the via conductors form coils formed in spiral shapes, and the flexible insulating substrate is wound more than one turn in a circumferential direction of the cylindrical shape such that the first surface on an inner side of the cylindrical shape and the second surface on an outer side of the cylindrical shape oppose each other.

Abstract: A planar transformer includes a coil substrate including a flexible substrate and multiple coils formed on the flexible substrate. The coil substrate is formed to have coil parts and coilless parts such that the coil parts have the coils and that the coilless parts do not have the coils, and the coil substrate is folded such that at least one of the coilless parts is sandwiched between two of the coil parts.

Abstract: A coil substrate for a motor includes a flexible substrate, and multiple coils formed on a surface of the flexible substrate. Each of the coils has a wiring having first wiring portions and second wiring portions extending from the first wirings respectively and is formed such that the first wiring portions extend parallel with respect to each other and that the second wiring portions extend not parallel to the first wirings, and the flexible substrate is formed to be formed around a magnet of a motor such that the first wiring portions form an angle that is substantially perpendicular to a rotation direction of the motor.
