摘要： A coil is a coil of a conductive wire that has a quadrangular cross section, that is spirally wound and laminated to have a series of turns including first to n-th turns (n is an integer of 3 or more), and that is provided, on at least some of the first to n-th turns in the coil, with deformed portions representing recesses each having a shape different from a shape of another portion of the conductive wire. In each of the first and n-th turns respectively lying at both ends of the series of turns, an outer surface lying on a side opposite to a center of the series of turns extends flush along with a plane intersecting the series of turns.

摘要： A motor includes a stator and a rotor at a predetermined distance from the stator. The stator includes an annular yoke, a plurality of teeth connected to the inner circumference of the yoke, and a plurality of coils each wound around an associated one of the teeth. Each coil has coil ends at both ends in an axial direction. At least one of the coil ends has, in an end surface thereof in the axial direction, a first recess extending along the radius of the stator. The first recess houses a first wiring member connecting the coils together.

摘要： A stator includes a yoke, teeth connected to the yoke, and coils including plate-shaped conductive wire and mounted on respective teeth. Each coil includes a wound part, a first and second terminals. The wound part is wound around the tooth n turns (n is an integer equal to or greater than 2). The wound part satisfies a relationship represented by Ak

摘要： A coil device includes a first coil including a plate-shaped first coil body having a first and second end. The first coil body is spirally wound on a columnar portion along the extending direction of the columnar portion such that the second end is positioned on one side in the extending direction relative to the first end. The coil device further includes a second coil including a plate-shaped second coil body having a third end and a fourth end. The second coil body is spirally wound on the columnar portion along the extending direction such that the third end is positioned on the one side in the extending direction relative to the second end of the first coil, and the fourth end is positioned on the one side in the extending direction relative to the third end. The second coil is in electrically parallel connection with the first coil.
