【０００２】
【従来の技術】
一般に、リニア直流モータは脈動を伴わない推力を発生し得る唯一のリニア・モータであり、各種位置検出装置等を装着してサーボ制御することにより推力および速度の広範囲の制御と、停止位置の高精度の制御とを可能とし、振動および推力変動を嫌う負荷と、広範囲の速度での運転を必要とする負荷とに対応し得る唯一のリニア・アクチュエータであり、偏平コイル形リニア直流モータは、固定子の薄型化および可動子の軽量化を可能とする優れた応答性を有するリニア直流モータである。
【０００３】
従来の偏平コイル形リニア直流モータの構造および動作を、図１および図２に示す断面図と、図３および図４に示す推力特性図とにより説明する。
【０００４】
図１および図２に示す従来の偏平コイル形リニア直流モータは、所定の距離を隔て相対する第１の構成部材８と第２の構成部材９とを備え、それぞれの相対面が構成する空間２１内に方向の異なる二つの磁界を形成し、空間２１を介して一つの閉磁路を形成する固定子１と、第１の偏平コイル１２を備え、空間２１内を自由に移動し得る構造に配置される可動子１１とにより構成される。
【０００５】
第１の構成部材８は、平板状をなす第１のヨーク２と、第１のヨーク２の第２の構成部材９への相対面の中央部から矢印Ａ方向の端部までの範囲にＮ極の極性を有する磁極面が固着される第１の永久磁石４と、第１のヨーク２の第２の構成部材９への相対面の中央部から矢印Ｂ方向の端部までの範囲にＳ極の極性を有する磁極面が固着される第２の永久磁石５とにより構成される。
【０００６】
第２の構成部材９は、平板状をなす第２のヨーク３により構成される。
【０００７】
尚、図１に示す従来の偏平コイル形リニア直流モータにおいて、第１の永久磁石４と第２の永久磁石５とは、隣接して第１のヨーク２に配置され、図２に示す従来の偏平コイル形リニア直流モータにおいて、第１の永久磁石４と第２の永久磁石５とは、それぞれが影響を及ぼさない所定の距離を隔て第１のヨーク２に配置される。
【０００８】
固定子１は、第１の永久磁石４のＮ極の極性を有する磁極面から、第１のヨーク２の内部を通り、第２の永久磁石５のＳ極の極性を有する磁極面に至り、第２の永久磁石５のＮ極の極性を有する磁極面から、空間２１を介して第２のヨーク３の第２の永久磁石５への相対面に至り、第２のヨーク３の内部を通り、第２のヨーク３の第１の永久磁石４への相対面から、空間２１を介して第１の永久磁石４のＳ極の極性を有する磁極面に至る閉磁路３１を形成する。
【０００９】
可動子１１は、四つのコイル辺を備えた第１の偏平コイル１２を主に構成され、第１の永久磁石４の第２のヨーク３への相対面が構成する空間２１の範囲に第１のコイル辺１３が位置し、第２の永久磁石５の第２のヨーク３への相対面が構成する空間２１の範囲に第２のコイル辺１４が位置し、空間２１内を矢印Ａ方向および矢印Ｂ方向に自由に移動し得る構造に配置され、第１の偏平コイル１２に図示の方向に所定の電流を流すことにより所定の推力をもって矢印Ｂ方向に移動し、第１の偏平コイル１２に図示と異なる方向に所定の電流を流すことにより所定の推力をもって矢印Ａ方向に移動する。
【００１０】
可動子１１の移動範囲、即ち、偏平コイル形リニア直流モータのストロークは、第１のコイル辺１３の矢印Ａ方向の端部が第１の永久磁石４の矢印Ａ方向の端部に相対する位置から第１のコイル辺１３の矢印Ｂ方向の端部が第１の永久磁石４の矢印Ｂ方向の端部に相対する位置まで移動する距離、あるいは第２のコイル辺１４の矢印Ａ方向の端部が第２の永久磁石５の矢印Ａ方向の端部に相対する位置から第２のコイル辺１４の矢印Ｂ方向の端部が第２の永久磁石５の矢印Ｂ方向の端部に相対する位置まで移動する距離である。
【００１１】
図３は図１に示す従来の偏平コイル形リニア直流モータの推力特性図であり、図４は図２に示す従来の偏平コイル形リニア直流モータの推力特性図である。
【００１２】
図３および図４は、ストロークｘ［ｍｍ］を６［ｍｍ］に設定し、可動子１１を構成する第１の偏平コイル１２に、図１あるいは図２に示す方向に所定の電流を流し、可動子１１が矢印Ａ方向の端部から矢印Ｂ方向の端部まで移動する際、あるいは第１の偏平コイル１２に、図示と異なる方向に所定の電流を流し、可動子１１が矢印Ｂ方向の端部から矢印Ａ方向の端部まで移動する際の推力特性図である。
【００１３】
曲線Ａおよび直線Ａは第１の偏平コイル１２にＩ［Ａ］の電流を流した際の推力特性であり、曲線Ｂは第１の偏平コイル１２に３×Ｉ［Ａ］の電流を流した際の推力特性であり、曲線Ｃは第１の偏平コイル１２に５×Ｉ［Ａ］の電流を流した際の推力特性である。
【００１４】
図３に示す推力特性図において、曲線Ａは０．８×Ｆａ［Ｎ］からＦａ［Ｎ］まで増加し、Ｆａ［Ｎ］から０．８×Ｆａ［Ｎ］まで減少する推力が可動子１１に作用する状態を示し、曲線Ｂは２．５×Ｆａ［Ｎ］から３×Ｆａ［Ｎ］まで増加し、３×Ｆａ［Ｎ］から２×Ｆａ［Ｎ］まで減少する推力が可動子１１に作用する状態を示し、曲線Ｃは４×Ｆａ［Ｎ］から５×Ｆａ［Ｎ］まで増加し、５×Ｆａ［Ｎ］から３×Ｆａ［Ｎ］まで減少する推力が可動子１１に作用する状態を示す。
【００１５】
図４に示す推力特性図において、直線ＡはＦａ［Ｎ］の推力が可動子１１の位置にかかわらず可動子１１に作用する状態を示し、曲線Ｂは３×Ｆａ［Ｎ］から２．５×Ｆａ［Ｎ］まで減少する推力が可動子１１に作用する状態を示し、曲線Ｃは４．５×Ｆａ［Ｎ］から３．５×Ｆａ［Ｎ］まで減少する推力が可動子１１に作用する状態を示す。
【００１６】
図１に示す従来の偏平コイル形リニア直流モータは、小型化、軽量化および低価格化を目的としたものであり、通常、図３の曲線Ｂで示される推力特性の状態で使用され、全ストロークに対し両端部の推力が小さく成る問題点を有し、図２に示す従来の偏平コイル形リニア直流モータは、ロング・ストローク化を目的としたものであり、通常、図４の曲線Ｂで示される推力特性の状態で使用され、可動子１１の大型化、応答性の劣化および可動子１１の移動に伴い推力が減少する問題点を有するものである。
【００１７】
一般に、偏平コイル形リニア直流モータの推力は、可動子を構成する偏平コイルに鎖交する固定子が形成する閉磁路を流れる磁束あるいは偏平コイルが位置する範囲の磁界と、偏平コイルの巻数と、偏平コイルに流れる電流とに比例して増加する。
【００１８】
図１あるいは図２に示す従来の偏平コイル形リニア直流モータの大推力化は、第１の偏平コイル１２を構成する第１のコイル辺１３および第２のコイル辺１４に鎖交する磁束の増加と、第１の偏平コイル１２の巻数の増加と、第１の偏平コイル１２に流れる電流の増加とにより可能に成る。しかし、第１の偏平コイル１２に鎖交する磁束の増加は、固定子１の大型化、大重量化および高価格化等の問題点を有し、第１の偏平コイル１２の巻数の増加は、可動子１１の大型化、大重量化、応答性の劣化およびストロークの減少等の問題点を有するため、第１の偏平コイル１２に流れる電流の増加により対処されている。
【００１９】
図１あるいは図２に示す従来の偏平コイル形リニア直流モータの可動子１１を構成する第１の偏平コイル１２に流れる電流の増加は、第１のコイル辺１３および第２のコイル辺１４の周囲に発生する磁界の傾斜を大きくし、第１の永久磁石４および第２の永久磁石５が空間２１内に形成する磁界の分布に傾斜を与え、図３あるいは図４に示す推力特性の曲線Ｂあるいは曲線Ｃに示すように、推力が可動子１１の移動に伴い大きく変動する。
【００２０】
図１あるいは図２に示す従来の偏平コイル形リニア直流モータは、小型化、軽量化、薄型化、低価格化および可動子の軽量化に伴う応答性の向上を可能とする反面、ロング・ストローク化、大電流化による推力の増加および推力変動の減少を困難とする問題点を有するものである。
【００２１】
【発明が解決しようとする課題】
解決しようとする問題点は、従来の偏平コイル形リニア直流モータの大推力化と全ストロークに対する推力変動の減少とを共に実現することが困難である点である。
【００２２】
【課題を解決するための手段】
従来の偏平コイル形リニア直流モータの空間２１の中央部から一方の端部までの範囲を構成する固定子１の構成部材と、空間２１の中央部から他方の端部までの範囲を構成する固定子１の構成部材とに、それぞれ一組の巻線あるいは偏平コイルを装着することを最も主要な特徴とし、可動子１１を構成する第１の偏平コイル１２の大電流化による大推力化および全ストロークに対する推力変動を減少させるという目的を極めて簡単に実現した。

[0002]
[Prior art]
In general, linear DC motors are the only linear motors that can generate thrust without pulsation. A wide range of thrust and speed can be controlled by installing various position detection devices, etc. This is the only linear actuator that can control the accuracy and can handle loads that do not like vibration and thrust fluctuations, and loads that require operation over a wide range of speeds. This is a linear direct current motor having excellent responsiveness that enables the child to be thin and the mover to be light.
[0003]
The structure and operation of a conventional flat coil linear DC motor will be described with reference to cross-sectional views shown in FIGS. 1 and 2 and thrust characteristic diagrams shown in FIGS. 3 and 4. FIG.
[0004]
The conventional flat coil type linear direct current motor shown in FIGS. 1 and 2 includes a first component member 8 and a second component member 9 which are opposed to each other at a predetermined distance, and a space 21 formed by the respective relative surfaces. A stator 1 that forms two magnetic fields in different directions and forms one closed magnetic path through the space 21 and a first flat coil 12 are arranged in a structure that can move freely in the space 21. The movable element 11 is configured.
[0005]
The first component member 8 has a flat plate-shaped first yoke 2 and N in a range from the center portion of the relative surface of the first yoke 2 to the second component member 9 to the end portion in the arrow A direction. The first permanent magnet 4 to which the pole face having the polarity of the pole is fixed and the range from the center of the relative surface of the first yoke 2 to the second component member 9 to the end in the direction of the arrow B are S. It is comprised with the 2nd permanent magnet 5 to which the magnetic pole surface which has the polarity of a pole is fixed.
[0006]
The second component member 9 is constituted by a second yoke 3 having a flat plate shape.
[0007]
In the conventional flat coil type linear direct current motor shown in FIG. 1, the first permanent magnet 4 and the second permanent magnet 5 are disposed adjacent to the first yoke 2, and the conventional permanent magnet shown in FIG. In the flat coil type linear direct current motor, the first permanent magnet 4 and the second permanent magnet 5 are arranged on the first yoke 2 with a predetermined distance that does not affect each other.
[0008]
The stator 1 passes from the magnetic pole surface having the N-polarity of the first permanent magnet 4 to the magnetic pole surface having the S-polarity of the second permanent magnet 5 through the inside of the first yoke 2. From the magnetic pole surface of the second permanent magnet 5 having the N-pole polarity to the relative surface of the second yoke 3 to the second permanent magnet 5 through the space 21, the interior of the second yoke 3 is passed. A closed magnetic path 31 is formed from the relative surface of the second yoke 3 to the first permanent magnet 4 to the magnetic pole surface having the polarity of the S pole of the first permanent magnet 4 via the space 21.
[0009]
The mover 11 is mainly configured by a first flat coil 12 having four coil sides, and the first in a range of a space 21 formed by a relative surface of the first permanent magnet 4 to the second yoke 3. Coil side 13 is located, second coil side 14 is located in the range of space 21 formed by the relative surface of second permanent magnet 5 to second yoke 3, and the inside of space 21 is in the direction of arrow A and Arranged in a structure that can freely move in the direction of arrow B, and by moving a predetermined current through the first flat coil 12 in the direction shown in the figure, the first flat coil 12 moves in the direction of arrow B with a predetermined thrust. It moves in the direction of arrow A with a predetermined thrust by flowing a predetermined current in a direction different from the figure.
[0010]
The moving range of the mover 11, that is, the stroke of the flat coil type linear direct current motor, is a position where the end of the first coil side 13 in the direction of arrow A is opposite to the end of the first permanent magnet 4 in the direction of arrow A. From which the end of the first coil side 13 in the direction of arrow B moves to a position opposite to the end of the first permanent magnet 4 in the direction of arrow B, or the end of the second coil side 14 in the direction of arrow A The end of the second coil side 14 in the direction of arrow B faces the end of the second permanent magnet 5 in the direction of arrow B from the position where the portion faces the end of the second permanent magnet 5 in the direction of arrow A. The distance traveled to the position.
[0011]
FIG. 3 is a thrust characteristic diagram of the conventional flat coil linear DC motor shown in FIG. 1, and FIG. 4 is a thrust characteristic diagram of the conventional flat coil linear DC motor shown in FIG.
[0012]
3 and 4, the stroke x [mm] is set to 6 [mm], a predetermined current is passed through the first flat coil 12 constituting the mover 11 in the direction shown in FIG. 1 or FIG. When the mover 11 moves from the end in the direction of arrow A to the end in the direction of arrow B, or when a predetermined current is passed through the first flat coil 12 in a direction different from the illustration, the mover 11 moves in the direction of arrow B. It is a thrust characteristic figure at the time of moving from an edge part to the edge part of the arrow A direction.
[0013]
A curve A and a straight line A are thrust characteristics when a current of I [A] is passed through the first flat coil 12, and a curve B is a current of 3 × I [A] passed through the first flat coil 12. The curve C is the thrust characteristic when a current of 5 × I [A] is passed through the first flat coil 12.
[0014]
In the thrust characteristic diagram shown in FIG. 3, the curve A increases from 0.8 × Fa [N] to Fa [N], and the thrust that decreases from Fa [N] to 0.8 × Fa [N] is the mover 11. The curve B is increased from 2.5 × Fa [N] to 3 × Fa [N], and the thrust which decreases from 3 × Fa [N] to 2 × Fa [N] is shown in FIG. The curve C increases from 4 × Fa [N] to 5 × Fa [N], and the thrust that decreases from 5 × Fa [N] to 3 × Fa [N] acts on the mover 11. Indicates the state to be performed.
[0015]
In the thrust characteristic diagram shown in FIG. 4, the straight line A shows a state in which the thrust of Fa [N] acts on the mover 11 regardless of the position of the mover 11, and the curve B is 3 × Fa [N] to 2.5 A state in which thrust that decreases to × Fa [N] acts on the mover 11 is shown, and a curve C indicates that thrust that decreases from 4.5 × Fa [N] to 3.5 × Fa [N] acts on the mover 11. Indicates the state to be performed.
[0016]
The conventional flat coil type linear direct current motor shown in FIG. 1 is intended for miniaturization, weight reduction and price reduction, and is normally used in the state of the thrust characteristic shown by curve B in FIG. The conventional flat coil type linear direct current motor shown in FIG. 2 has the problem that the thrust at both ends becomes small with respect to the stroke. It is used in the state of the thrust characteristics shown, and has a problem that the thrust is reduced as the mover 11 is enlarged, the response is deteriorated, and the mover 11 is moved.
[0017]
In general, the thrust of the flat coil type linear direct current motor includes the magnetic flux flowing in the closed magnetic path formed by the stator linked to the flat coil constituting the mover or the magnetic field in the range where the flat coil is located, the number of turns of the flat coil, It increases in proportion to the current flowing through the flat coil.
[0018]
The increase in the thrust of the conventional flat coil type linear DC motor shown in FIG. 1 or FIG. 2 is an increase in the magnetic flux interlinking with the first coil side 13 and the second coil side 14 constituting the first flat coil 12. This can be achieved by increasing the number of turns of the first flat coil 12 and increasing the current flowing through the first flat coil 12. However, the increase in the magnetic flux linked to the first flat coil 12 has problems such as an increase in the size, weight, and cost of the stator 1, and an increase in the number of turns of the first flat coil 12 Since the movable element 11 has problems such as an increase in size, weight, deterioration in responsiveness, and reduction in stroke, it is addressed by an increase in the current flowing through the first flat coil 12.
[0019]
The increase in current flowing in the first flat coil 12 constituting the mover 11 of the conventional flat coil type linear direct current motor shown in FIG. 1 or FIG. 2 is caused around the first coil side 13 and the second coil side 14. Is increased, the distribution of the magnetic field formed in the space 21 by the first permanent magnet 4 and the second permanent magnet 5 is inclined, and the thrust characteristic curve B shown in FIG. 3 or FIG. Alternatively, as shown by the curve C, the thrust greatly varies with the movement of the mover 11.
[0020]
The conventional flat coil type linear direct current motor shown in FIG. 1 or FIG. 2 is capable of improving the responsiveness associated with downsizing, weight reduction, thickness reduction, price reduction and weight reduction of the mover, but long stroke. The problem is that it is difficult to increase thrust and decrease thrust fluctuation due to increase in current and current.
[0021]
[Problems to be solved by the invention]
The problem to be solved is that it is difficult to achieve both a large thrust of a conventional flat coil linear DC motor and a reduction in thrust fluctuation with respect to the entire stroke.
[0022]
[Means for Solving the Problems]
The constituent member of the stator 1 constituting the range from the central portion of the space 21 of the conventional flat coil type linear direct current motor to one end, and the fixing constituting the range from the central portion of the space 21 to the other end. The most important feature is that a set of windings or flat coils are respectively attached to the constituent members of the child 1, and the first flat coil 12 constituting the mover 11 has a large thrust due to an increase in current and all the features. The objective of reducing the thrust fluctuation with respect to the stroke was realized very easily.
[0023]
