ら見て同一とされている。"Prior Art" In recent years, there has been a demand for small and thin coils for small motors. In response to this demand, flat coils such as printed coils formed by etching, plating, or a combination thereof, that is, by so-called printed wiring technology, are used. One embodiment of this flat coil is shown in FIG. That is, a metal conductor 12 is formed in a rectangular spiral shape on one surface of an insulating layer (insulating sheet) 11 to form a micro coil 13. In this example, two microcoils 13 are arranged side by side, their winding directions are opposite to each other, and they are connected to each other on the outside. Although not shown in the figure, microcoils are formed on the other surface of the insulating layer 11, facing each other with the insulating layer 11 in between, and are connected to each other through the insulating layer 11 at the inner end 14 of the coil 13. The winding directions are the same when viewed from the same direction.

はコイルの巻き数が多いほど大きい。その為、で
きるだけ多くの巻き数がとれる様にコイルパター
ンが作られている。 The greater the number of turns of the coil, the greater the torque acting on the coil or magnet due to the interaction between the magnetic flux based on the current flowing through the coil and the magnet. For this reason, coil patterns are created so that as many turns as possible can be taken.

も小さくなるという問題点が生じる。``Problems that the invention attempts to solve'' In this way, the flat coil, which has a large number of windings and is made small, has a long conductor length.
A problem arises in that the electrical resistance increases, and therefore the current flowing at the same voltage decreases, and the torque acting on the coil or magnet also decreases.

することを目的とする。"Means and actions for solving the problems" This invention is a flat coil for motors that does not have the above problems, that is, a flat coil for motors in which a rectangular spiral microcoil is formed with metal conductive wire on an insulating layer. The width of each part constituting one of the two opposing sides of the conducting wire is larger than the width of each part constituting the other two opposing sides, and the extending direction of the larger part is By making the part almost perpendicular to both the direction of relative movement between the drive magnetic field and this flat coil when attached to the motor, and the magnetic field, the effective conductor part for the torque acting on the coil or magnet can be increased. To provide a flat coil capable of reducing the electrical resistance of the coil while ensuring its length, thereby increasing the current flowing at the same voltage, and increasing the torque acting on the coil or magnet.
なおコイルあるいは磁石に働くトルクは、コイ

短くなり、コイルの抵抗が小さくなつても大きな
トルクが得られない。 The torque acting on a coil or magnet is proportional to the length (effective length) of the coil conductor in the direction perpendicular to the direction in which the magnetic field moves across the coil and the current flowing through the coil. When the width W of the coil 12 is widened in all parts, the length (effective length) of the effective portion of the coil (effective length) l 1 +l 2 +...+l o becomes shorter in the insulating layer 11 having a certain limited width or size. Even if the coil resistance is reduced, large torque cannot be obtained.

きる。 Therefore, in this invention, as shown in the embodiment shown in FIG. 1, the width of the conductor portion 12a in the direction perpendicular to the direction in which the magnetic field moves across the coil is increased. In this rectangular coil, the width of the conductor portion 12a forming one opposing side of the rectangle is wide, and the width of the conductor portion 12b forming the other opposing side of the rectangle is narrow.
In this way, the resistance of the coil can be reduced without changing the overall conductor width of the coil or the size of the coil, and without reducing the available effective length.

ことが好ましい。このようにして効率的にコイル
１６の抵抗を下げることができる。 This idea can also be applied to circular multipolar coils. For example, as shown in FIG. 2, a plurality of rectangular coils 16 close to trapezoids are formed at equal angular intervals on the circular insulating layer 11 with its center 15 as the center, and the conductor portions 17a are arranged in a substantially radial direction with respect to the center 15. The conductor portion 17 is widened and extends in the circumferential direction with respect to the center 15.
Narrow the width of b. It is preferable that the conductor width of the conductor portion 17a increases continuously as it approaches the outer side with respect to the center 15. In this way, the resistance of the coil 16 can be efficiently lowered.

で磁束方向が逆になるようにされる。 The coil 16 is also formed to face the back surface of the insulating layer 11, and the coils 16 on both sides are connected in series, and when a current is passed through this, the magnetic fluxes generated from the coils on both sides are added, and the adjacent coils 16 are connected in series. The direction of magnetic flux is reversed between the coils.

Gap between conductor G 1 (Fig. 1) and thin part 12b
It is preferable that G 2 be the same or that G 1 >G 2 .
More preferably, the ratio of the conductor width to the gap is constant. Or the part to be thickened 12
The length of a, 17a is at least 1/2, more preferably at least 2/3, and even more preferably all of the length of the conductor in the direction perpendicular to the direction in which the magnetic field moves across the coil.

る。``Effects'' The flat coil of this invention has a conductor width partially thickened in only one opposing conductor part of the rectangular spiral conductor, so it can be used in motors without increasing the size of the coil. The resistance can be reduced without reducing the effective length for the torque acting on the coil or magnet. Therefore, with the same voltage, a large current can flow and torque can be increased.
