Description
本發明與馬達有關,尤指一種應用於壓縮機的線性馬達。The invention relates to motors, and more particularly to a linear motor for use in a compressor.
目前中小型、家用的冷凍空調設備,如冰箱或是冷氣機等,依舊是以往復式壓縮機為大宗,而壓縮機內的動力源則是旋轉式馬達,並再透過曲柄滑塊機構、或是凸輪機構將旋轉式馬達的旋轉運動轉換為直線運動,以曲柄滑塊機構而言,將曲柄的部分由旋轉馬達帶動旋轉,而滑塊則作為往復式壓縮機的活塞部分,若以凸輪機構而言,就是由旋轉馬達帶動凸輪旋轉,而凸輪再去推頂活塞使之前後移動。這兩種機構均可將旋轉運動轉換為直線運動,但是缺點在於這些機構都有許多的可動元件,無疑增加了成本,而且這些元件本身也多有使用壽命的限制,進而增加了保養的困難。此外,這些可動元件相互之間也有摩擦力產生,而這些摩擦力即會造成能量的耗損,減損了馬達所傳送的動力,亦降低了壓縮機的效率。At present, small and medium-sized, domestic refrigerating and air-conditioning equipment, such as refrigerators or air-conditioners, are still mainly reciprocating compressors, and the power source in the compressor is a rotary motor, and then through the crank slider mechanism, or The cam mechanism converts the rotary motion of the rotary motor into a linear motion. In the case of the crank slider mechanism, the crank portion is rotated by the rotary motor, and the slider is used as the piston portion of the reciprocating compressor. In other words, the rotary motor drives the cam to rotate, and the cam then pushes the top piston to move forward and backward. Both of these mechanisms convert rotary motion into linear motion, but the disadvantage is that these mechanisms have many movable components, which undoubtedly increase the cost, and the components themselves have a limited life limit, which increases the difficulty of maintenance. In addition, these movable elements also have frictional forces with each other, and these frictional forces cause energy loss, which detracts from the power transmitted by the motor and reduces the efficiency of the compressor.
為了省略掉上述的旋轉/直線運動轉換機構,有人提出了以線性馬達取代旋轉馬達的構想,如此一來,馬達的運動本身就是線性的而不需要另外的機構將旋轉運動轉換為直線運動。由此可見,使用了線性馬達之後即可擺脫掉旋轉/直線運動轉換機構所帶來的成本、保養不易、與磨耗的問題。In order to omit the above-described rotary/linear motion conversion mechanism, a concept of replacing a rotary motor with a linear motor has been proposed, so that the motion of the motor itself is linear without requiring an additional mechanism to convert the rotational motion into a linear motion. It can be seen that the use of a linear motor can eliminate the cost, maintenance and wear of the rotary/linear motion conversion mechanism.
其中一個習用技術是美國專利6184597號,然而其缺點在於其動子的體積過於龐大。One of the conventional techniques is U.S. Patent No. 6,184,597, however, the disadvantage is that the size of the mover is too large.
另一習用技術是美國專利6946754號,其定子的線圈是以動子的運動軸向為圓心而繞線,並且動子是整個放置於定子線圈內,因此其矽鋼片是以環繞動子的方式排列,而矽鋼片的平面則是平行於動子的運動軸向,又若以平行於動子運動軸向的視線觀察定子的矽鋼片排列,則可以看到矽鋼片是放射狀環繞於動子而排列。此技術的缺點在於矽鋼片由於是放射狀的排列,故而愈朝向定子外側的各矽鋼片之間的空隙就愈大,致使電磁效率的降低。且為了避免各矽鋼片之間的空隙不均勻,在排列矽鋼片的時候必須更加的注意,或是使用其他的零組件以維持住上述各空隙的均勻,如此反而又使得成本增加。Another conventional technique is U.S. Patent No. 6,946,754, in which the coil of the stator is wound with the moving axis of the mover as the center of the circle, and the mover is placed entirely in the stator coil, so that the steel piece is surrounded by the mover. Arranged, and the plane of the silicon steel sheet is parallel to the moving axis of the mover, and if the stator steel sheet is aligned with the line of sight parallel to the moving axis of the mover, it can be seen that the silicon steel sheet is radially surrounded by the mover. And arranged. The disadvantage of this technique is that the silicon steel sheets are radially arranged, so that the larger the gap between the steel sheets facing the outside of the stator, the lower the electromagnetic efficiency. In order to avoid the unevenness of the gap between the steel sheets, it is necessary to pay more attention when arranging the steel sheets, or to use other components to maintain the uniformity of the above gaps, which in turn increases the cost.
還有一習用技術是美國專利5945748號,其動子的結構一如上述的US6184597案,體積較龐大,而其定子的結構一如上述的US6946754案是以動子的運動軸向為圓心呈放射狀排列,故而也有上述的問題。Another conventional technique is U.S. Patent No. 5,945,748. The structure of the mover is as described in the above-mentioned U.S. Patent No. 6,184,597, which is bulky, and the structure of the stator is as in the above-mentioned US6946754. The moving axis of the mover is radially centered. Arranged, so there are problems as mentioned above.
由上述各習用技術可知,線性馬達的構想是十分理想的,但是各習用技術的解決方案並不完善,故而需要一種新的思維,使線性馬達更趨近於完美。As can be seen from the above various conventional techniques, the concept of a linear motor is very desirable, but the solutions of various conventional technologies are not perfect, so a new thinking is required to make the linear motor more perfect.

本發明所欲提供的即是一種應用於壓縮機的線性馬達,以解決以往各習用技術的缺點。What the present invention is intended to provide is a linear motor for use in a compressor to solve the shortcomings of the prior art.
請參閱圖1,為本發明的實施例側剖視圖。其中所揭示的壓縮機1具有一殼體10與一汽缸室12,汽缸室12還與一進氣口12a、一排氣口12b, 而活塞30則位於汽缸室12內用以將其中的氣體(通常是冷媒)壓縮,未壓縮的氣體自進氣口12a進入汽缸室12,經活塞30的壓縮後再由排氣口12b排出汽缸室12。由於本發明是一個線性馬達,故而活塞30實際上就是直接的固定在動子3上,動子3的構造大致上是有一軸桿32,在軸桿32的一端即是活塞30,而另一端則是彈簧4,用以提供回復力並對動子3的移動作一定程度的限制。又,動子3的運動方向則是軸向31,通常與軸桿32的幾何軸向是重疊的。在動子3上沿著軸向31則疊合有多個動子矽鋼片36,並在動子矽鋼片36外套設一動子磁石34(通常是一永久磁鐵)。Please refer to FIG. 1, which is a side cross-sectional view of an embodiment of the present invention. The compressor 1 disclosed therein has a casing 10 and a cylinder chamber 12, and the cylinder chamber 12 is also connected to an intake port 12a and an exhaust port 12b. The piston 30 is located in the cylinder chamber 12 for compressing the gas therein (usually a refrigerant), and the uncompressed gas enters the cylinder chamber 12 from the intake port 12a, and is compressed by the piston 30 and then discharged from the cylinder through the exhaust port 12b. Room 12. Since the present invention is a linear motor, the piston 30 is actually directly fixed to the mover 3. The structure of the mover 3 is substantially a shaft 32, at one end of the shaft 32 is the piston 30, and the other end It is a spring 4 for providing a restoring force and limiting the movement of the mover 3 to a certain extent. Again, the direction of movement of the mover 3 is the axial direction 31, which generally overlaps the geometrical axial direction of the shaft 32. A plurality of mover steel sheets 36 are superposed on the mover 3 along the axial direction 31, and a mover magnet 34 (usually a permanent magnet) is jacketed on the mover steel sheet 36.
請繼續參閱圖1,其中在殼體10內圍繞著動子的空間則固定了一第一定子21與一第二定子22,在第一定子21上靠近動子3的部分(即圖2的繞線部20)則纏繞有第一定子線圈210、而在第二定子22上靠近動子3的部分(即圖2的繞線部20)則纏繞有第二定子線圈220,當各定子線圈通電時,即產生磁場,以動子3上半部分的第一定子21與第二定子22而言,由於其第一定子線圈210與第二定子線圈220纏繞方向相反,故而當通電時,在第一定子21的上方的極性是N極、下方則為S極;相反的,在第二定子22的上方的極性是S極、下方則為N極。而動子3的外側是N極,故而與第二定子22相斥而與第一定子21相吸,因此,動子3會向圖1圖面的左方移動,並推動活塞30壓縮冷煤。而如使用交流電,則當下次交換電流方向時,第一定子21的下方就變為N極,而第二定子22的下方則變為S極,如此動 子3即與第一定子21互斥而與第二定子22相吸,動子3即會朝右移動。由此亦可見一個第一定子線圈210與一個第二定子線圈220可以各自組成一個磁極組合。Referring to FIG. 1 , a space surrounding the mover in the casing 10 fixes a first stator 21 and a second stator 22 on the first stator 21 near the mover 3 (ie, The winding portion 20 of 2 is wound with the first stator coil 210, and the portion of the second stator 22 close to the mover 3 (ie, the winding portion 20 of FIG. 2) is wound with the second stator coil 220. When the stator coils are energized, a magnetic field is generated. In the first stator 21 and the second stator 22 of the upper half of the mover 3, since the first stator coil 210 and the second stator coil 220 are wound in opposite directions, When energized, the polarity above the first stator 21 is the N pole and the lower side is the S pole; conversely, the polarity above the second stator 22 is the S pole and the lower side is the N pole. The outer side of the mover 3 is an N pole, so it is repelled with the second stator 22 and sucks with the first stator 21. Therefore, the mover 3 moves to the left of the plane of FIG. 1 and pushes the piston 30 to compress cold. coal. On the other hand, if AC power is used, when the current direction is exchanged next time, the lower side of the first stator 21 becomes the N pole, and the lower side of the second stator 22 becomes the S pole. The sub 3 is mutually exclusive with the first stator 21 and sucks with the second stator 22, and the mover 3 moves to the right. It can also be seen that a first stator coil 210 and a second stator coil 220 can each form a magnetic pole combination.
請參閱圖2,為本發明定子與動子的正面示意圖。其中是以動子3的軸向31去觀察第一、二定子(21、22)以及動子3本身,其中可見各定子實際上係由多個矽鋼片疊合而成,其內徑係套在動子3的外徑上,每個定子(21、22)上均具有一繞線部20,為了平均磁力的分布,繞線部20通常有四個,以第一定子21而言,各繞線部20上分別纏繞有第一定子一號線圈210a、第一定子二號線圈210b、第一定子三號線圈210c、以及第一定子四號線圈210d。同理,第二定子22的各繞線部20亦分別纏繞有第二定子一號線圈220a、第二定子二號線圈220b、第二定子三號線圈220c、以及第二定子四號線圈220d。相鄰的兩個繞線部20夾角九十度,且其上的線圈的纏繞方向相反,如以定子中心向繞線部20觀察,若第一定子一號線圈210a為順時針纏繞,則第一定子二號線圈210b則為逆時針纏繞。因此一、三號線圈的纏繞方向同為順時針,而二、四號線圈的纏繞方向同為逆時針。此外,各線圈的纏繞當然具有一纏繞軸向,此軸向剛好即是定子的徑向。又,當通電的時候,同方向纏繞的線圈,其磁力線也是同個方向,故以第一定子21而言,其一、三號線圈的磁力方向同是由內向外,而二、四號線圈的磁力方向同是由外向內;同理,由圖1及其說明可知,第一定子一號線圈210a與第二定子一號線 圈220a於通電時需極性相反,故如以定子中心向繞線部20觀察,若第二定子一號線圈220a為逆時針纏繞,則第二定子二號線圈220b則為順時針纏繞。也因此以第二定子22而言,其一、三號線圈的磁力方向同是由外向內,而二、四號線圈的磁力方向同是由內向外。Please refer to FIG. 2 , which is a front view of the stator and the mover of the present invention. Wherein the first and second stators (21, 22) and the mover 3 themselves are observed in the axial direction 31 of the mover 3, wherein each stator is actually formed by stacking a plurality of silicon steel sheets, and the inner diameter sleeve is On the outer diameter of the mover 3, each of the stators (21, 22) has a winding portion 20, and for the distribution of the average magnetic force, there are usually four winding portions 20, in terms of the first stator 21, Each of the winding portions 20 is wound with a first stator first coil 210a, a first stator second coil 210b, a first stator third coil 210c, and a first stator fourth coil 210d. Similarly, each of the winding portions 20 of the second stator 22 is also wound with a second stator first coil 220a, a second stator second coil 220b, a second stator third coil 220c, and a second stator fourth coil 220d. The adjacent two winding portions 20 are at an angle of ninety degrees, and the winding directions of the coils thereon are opposite, as viewed from the center of the stator toward the winding portion 20, if the first stator first coil 210a is wound clockwise, The first stator second coil 210b is wound counterclockwise. Therefore, the winding directions of the first and third coils are clockwise, and the winding directions of the second and fourth coils are counterclockwise. Furthermore, the winding of each coil of course has a winding axial direction which is exactly the radial direction of the stator. Moreover, when energized, the coils wound in the same direction have the same magnetic field lines, so in the first stator 21, the magnetic directions of the first and third coils are from the inside to the outside, and the second and fourth numbers are The magnetic direction of the coil is the same from the outside to the inside; similarly, as shown in FIG. 1 and its description, the first stator first coil 210a and the second stator first line The ring 220a needs to have the opposite polarity when energized. Therefore, if the second stator first coil 220a is wound counterclockwise, the second stator second coil 220b is wound clockwise. Therefore, in the second stator 22, the magnetic directions of the first and third coils are the same from the outside to the inside, and the magnetic directions of the second and fourth coils are from the inside to the outside.
請繼續參閱圖2,其中動子3的軸桿32外套設堆疊的動子矽鋼片36,並在於動子矽鋼片36外套設動子磁石34。又,動子3的動子磁石34上亦可等分四個部分,其中上下兩部分的磁力線是由內向外,即上下兩部分的外側是N極、內側是S極;而左右兩部分的磁力線則是由外向內,即左右兩部分的外側是S極、內側是N極。亦即動子磁石34內的磁力線是與動子3的徑向平行。Referring to FIG. 2, the shaft 32 of the mover 3 is jacketed with a stack of mover steel sheets 36, and the mover steel sheet 36 is jacketed with a mover magnet 34. Moreover, the mover magnet 34 of the mover 3 can also be equally divided into four parts, wherein the magnetic lines of the upper and lower parts are from the inside to the outside, that is, the outer side of the upper and lower parts is the N pole, the inner side is the S pole; and the left and right parts are The magnetic lines of force are from the outside to the inside, that is, the outer sides of the left and right parts are the S pole and the inner side is the N pole. That is, the magnetic lines of force in the mover magnet 34 are parallel to the radial direction of the mover 3.
總而言之,各纏繞部20或是動子3上的磁力線的安排必需要在電流交換的時候,可以改變動子3的運動方向,就是適合的設定。In summary, the arrangement of the lines of magnetic force on each of the winding portions 20 or the mover 3 must change the direction of movement of the mover 3 when the current is exchanged, which is a suitable setting.
因此,本發明透過創新的繞線方法,以及矽鋼片的排列方式與形狀,使得動子的體積可以縮小,而定子的矽鋼片也不會有空隙產生,可增加磁力線的密度。所以本發明不但可以減少線性馬達的體積,還可以增進馬達的效率,進而提昇壓縮機的效率。Therefore, the invention can increase the volume of the mover through the innovative winding method and the arrangement and shape of the silicon steel sheet, and the stator steel sheet does not have a gap, which can increase the density of the magnetic lines. Therefore, the invention can not only reduce the volume of the linear motor, but also improve the efficiency of the motor, thereby improving the efficiency of the compressor.
