示す。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a printed coil unit for an actuator that is ultra-thin, compact, and low in cost. The actuator here consists of a coil, a magnetic circuit, etc., and converts electrical energy into mechanical energy using electromagnetic force.
For example, motors, rotary actuators,
Indicates a linear actuator, linear motor, etc.

In recent years, as audio equipment, video equipment, OA equipment, etc. have significantly advanced and become smaller and thinner, it has become desirable for the motors and actuators used in these equipment to be smaller and thinner. In general, motors and rotary actuators that aim to be small, especially thin, are divided evenly in the circumferential direction.
What is desired is a structure consisting of a magnetized rotor and a stator coil that is divided and wound in correspondence with its magnetic poles.

く、コイルも高くなる。 Also, recently, so-called printed coils, which are made by applying photolithography technology, have come into use. Especially when it comes to linear actuators where the distance (gap) between the magnet and yoke plate is less than 2m/m, motors and rotary actuators whose diameter is less than 30m/mφ and gap is less than 2m/m. With wire-wound coils, assembly such as winding the coil thinly and connecting spiral conductor patterns to each other is extremely difficult, and the coil is also expensive.
こうしたプリントコイルは、全有効面積にわた
り均一に、理論通りにコイルを配置することがで
き、そのため厚みを薄く抑えることができる。こ
のように全有効面積にわたり均一にコイルを配置
することを分散巻きと言われる。 In such a printed coil, the coils can be arranged uniformly and theoretically over the entire effective area, and therefore the thickness can be kept small. Arranging the coils uniformly over the entire effective area in this way is called distributed winding.

However, such printed coils are used in small and thin motors and actuators by taking advantage of the above characteristics, but these small and thin motors and actuators are equipped with elements for detecting the position of magnets placed opposite each other, such as Hall elements. The volume ratio of an element with a magnetic detection function, such as a magnetoresistive element, to the coil becomes very large, making it difficult to arrange it inside the motor. For example, if you try to place it on top of a coil, you would have to make the air gap large so that it would not catch on to the magnet placed opposite it, which would prevent you from taking advantage of the printed coil's ability to be wound thinly, and also reduce the main magnetic flux of the magnet. If placed outside, the magnetic detection sensitivity decreases, and a high sensitivity ratio of an amplifier for the magnetic detection element is required, making it difficult to obtain a good S/N ratio and increasing costs.

トを構成する場合もある。 That is, the present invention is a printed coil unit comprising a printed coil having a spiral conductor pattern, which includes at least one printed coil in which a magnetic detection element is arranged in the center of the spiral conductor pattern. Generally, the part of a motor or actuator that is made up of coils is called a coil unit.In the case of a coil unit that uses printed coils, it may be made up of a single printed coil, or

The size can be any size, but if it is a motor or rotary actuator, the diameter is 5 to 40 m/mφ, and the thickness is 0.1 to 2.
m/m is particularly effective. Also, in motors, rotary actuators, linear actuators, etc., the linear density of the coil part is 2 to 20 wires/
mm, more preferably 5 to 20 pieces/mm. Usually, the spiral pattern is formed on one or both sides of the printed coil support, and if necessary, the conductor patterns on both sides of the printed coil support are connected to each other by through holes so that they are electrically conductive. . The printed coil support may be of any material as long as it has electrical insulation properties, and for example, glass epoxy substrates, polyimide films, epoxy resins, etc. are preferably used. Further, any method may be used to form the through hole.

The shape of the conductor pattern may be a circle, a circle, a rectangle, or a combination thereof, but a fan shape with rounded corners is often used in flat type motors. In either case, a land for external connection or through-hole where the end of the spiral is maintained in the center of the spiral,
Provide a hole to attach the magnetic detection element. Furthermore, not only one magnetic detection element but also a plurality of magnetic detection elements may be attached to one central part of the spiral conductor pattern.
