〔産業上の利用分野〕
本発明はブラシレスモーターやいわゆるトランジスター
モーターなどに用いられるモーター用コイルに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a motor coil used in brushless motors, so-called transistor motors, and the like.
［従来の技術〕
従来、ブラシレスモーターやトランジスターモーターな
どに使用されるコイルは、一般に、ポリエステル等の絶
縁シート基板上にいわゆる巻線を施して製作していた。[Prior Art] Conventionally, coils used in brushless motors, transistor motors, and the like have generally been manufactured by forming so-called windings on an insulating sheet substrate made of polyester or the like.
上記“Ｓ線”は、銅線を巻線機で巻いて上記基板上に貼
附ける旧来の方法による他、上記基板上に銅等の導電材

イル化するなどの方法によって行われる。In addition to the traditional method of winding copper wire with a winding machine and attaching it to the above board, the above-mentioned "S wire" can be made by attaching a conductive material such as copper to the above board by electroless plating, etc., and then etching it. This is done by methods such as coiling using technology.
いずれにしても、従来のモーター用コイルでは、基板と
してポリエステル等の絶縁シートが使用されていた。In any case, in conventional motor coils, an insulating sheet made of polyester or the like is used as a substrate.
ところで、ポリエステル等の絶縁シート基板上にコイル
パターンを形成したコイルを用いたモーターで高出力を
得る方法には、コイルに流す電流を増加する方法、コイ
ルに強い磁界を印加する方法、あるいはこれら両方を用
いる方法がある。By the way, there are two ways to obtain high output from a motor using a coil with a coil pattern formed on an insulating sheet substrate such as polyester: increase the current flowing through the coil, apply a strong magnetic field to the coil, or both. There is a method using
すなわち、Ｆ＝Ｂｘｉｘｓｉｎθ
Ｆ： 発生力
Ｂ： 磁束密度
ｉ： 電流
の関係があることから、出力増大には電流ｉの増加また
は磁界強度のアンプが必要である。That is, F=Bxixsinθ F: Generated force B: Magnetic flux density i: Since there is a current relationship, an increase in the current i or an amplifier of the magnetic field strength is required to increase the output.
しかし、従来の絶縁シート基板を使用するモーター用コ
イルにあっては、実際にモーターを設計製作する場合、
モーター外径、永久磁石ライズおよび印加電流などに制
限があるため、その制限内で高出力を得ることは事実上
不可能であった。However, in the case of motor coils that use conventional insulating sheet substrates, when actually designing and manufacturing the motor,
Due to limitations on the motor's outer diameter, permanent magnet rise, applied current, etc., it was virtually impossible to obtain high output within these limits.
本発明は上記従来技術に鑑みなされたものであり、小電
流で高トルクが得られるモーター用コイルを提供するこ
とを目的とする。The present invention has been made in view of the above-mentioned prior art, and an object of the present invention is to provide a motor coil that can obtain high torque with a small current.

イルにより、上記目的を達成するものである。The present invention achieves the above object with a motor coil that uses a soft magnetic material sheet such as an amorphous sheet as a coil substrate, and that a coil is provided thereon after laminating and insulating the coil substrates. It is.
コイルパターンを形成する基板を、ポリイミド等の絶縁

により、永久磁石と固定子ヨークとの間における磁気抵
抗が小さくなり、磁束密度が高くなる。By using a substrate on which the coil pattern is formed, not an insulating sheet such as polyimide, but a soft magnetic material such as an amorphous sheet made by a roll method etc. that has been insulated, the connection between the permanent magnet and the stator yoke is improved. The magnetic resistance between the two becomes smaller, and the magnetic flux density becomes higher.
すなわち、コイルに印加される磁束密度が高くなるため
、小電流で高トルクのモーターが得られる。That is, since the magnetic flux density applied to the coil becomes high, a high torque motor can be obtained with a small current.
以下図面を参照して本発明を具体的に説明する。 The present invention will be specifically described below with reference to the drawings.

。According to the motor described above with reference to FIG. 1, the substrates 4a, 4b, and 4c forming the coil patterns are laminated with insulation-treated substrates made of a soft magnetic material such as an amorphous sheet made by a roll method or the like. As a result, it is possible to suppress the rotation of the permanent magnet 6 and the eddy current loss due to the coil current, and increase the magnetic flux between the permanent magnet and the stator yoke 2, that is, the magnetic flux perpendicular to the coil current.
このため、同一形状、同一永久磁石および同一電流にも
かかわらず、従来の絶縁シート基板を用いるものに比べ
、トルクの大きなモーターを提供することができた。Therefore, despite having the same shape, the same permanent magnet, and the same current, it was possible to provide a motor with larger torque than a motor using a conventional insulating sheet substrate.
モーター発生力すなわち回転子に働く磁力ＦはＦ＝Ｂｘ
ｉｘｓｉｎθで表される。The motor generated force, i.e. the magnetic force F acting on the rotor, is F=Bx

次に、本発明によってどの程度の磁束密度の増大を達成
できるかについて、数値例を挙げて説明する。Next, how much increase in magnetic flux density can be achieved by the present invention will be explained using numerical examples.
