Description
本發明係有關於一種無鐵心式線性馬達線圈組合件構造及其單元線圈，特別是指當線性馬達之單元線圈組為節省空間縮小體積，而使單元線圈彼此交錯並置時，單元線圈之中空部位留有間隙，用以容納間隔片，提高散熱或絕緣效果者。 The invention relates to a coreless linear motor coil assembly structure and a unit coil thereof, in particular to a hollow part of a unit coil when a unit coil group of a linear motor is space-saving and volume-reduced, and the unit coils are staggered and juxtaposed with each other. There is a gap to accommodate the spacers to improve heat dissipation or insulation.
一般無鐵心線性馬達如第十七圖與第十八圖所示，其包含一定子(X)及一動子(Y)，該動子(Y)沿著該定子(X)之軌道移動，該定子(X)由複數個永久磁鐵(M)隔著空隙交錯排列而成，以形成N極與S極交替之U形軌道(U)。其中該動子(Y)具有複數個線圈並排排列以形成線圈組，用以通入多相位的電流，例如較常被使用的三相線圈組，並於線圈組外包覆一樹脂封裝層(Z)，並置於一安裝台(W)之凹槽內。 A generally ironless linear motor, as shown in Figures 17 and 18, includes a stator (X) and a mover (Y) that moves along the orbit of the stator (X). The stator (X) is formed by staggering a plurality of permanent magnets (M) through a gap to form a U-shaped rail (U) in which N poles and S poles alternate. Wherein the mover (Y) has a plurality of coils arranged side by side to form a coil group for introducing a multi-phase current, such as a three-phase coil set which is often used, and covering a coil package with a resin encapsulation layer ( Z) and placed in the groove of a mounting table (W).
本案發明人曾提出中華民國專利第201126875號「線性馬達線圈組合件構造」，係利用複數個相鄰排列線圈之線圈組、一座體及一樹脂封裝層組成，該些線圈形成相對二直線作用邊，及相對之一非作用邊第一側及一非作用邊第二側，該些線圈於該非作用邊第一側形成複數個相互交錯之第一彎折段，並由該非作用邊 第二側設置複數根導線，該些導線於線圈組端部與外部纜線連結，該座體則設置一插接槽，其斷面形狀恰對應該些第一彎折段位置處之斷面形狀，並供該些線圈插置，該樹脂封裝層則包覆該些線圈，並密封該座體之插接槽，藉此增加該些線圈與該座體插接槽內壁之接觸面積，提高散熱速率，同時藉由線圈二直線作用邊的交錯並置，使得線圈組的體積得以變小。 The inventor of the present invention has proposed the "linear motor coil assembly structure" of the Republic of China Patent No. 201126875, which is composed of a plurality of coil groups, a body and a resin encapsulating layer of adjacently arranged coils, and the coils form a relative two-line acting edge. And the opposite one of the first side of the inactive side and the second side of the inactive side, the coils forming a plurality of mutually interlaced first bending sections on the first side of the inactive side, and the non-acting side The second side is provided with a plurality of wires, and the wires are connected to the external cable at the end of the coil group, and the seat body is provided with a plugging groove whose cross-sectional shape corresponds to the section at the position of the first bending segment. Forming and inserting the coils, the resin encapsulating layer covers the coils and sealing the insertion slots of the base body, thereby increasing the contact area between the coils and the inner wall of the socket insertion groove, The heat dissipation rate is increased, and at the same time, the volume of the coil group is reduced by the staggered juxtaposition of the sides of the coil.
另一美國專利編號US5998890中，提出一種無鐵心式線性馬達的線圈組結構，此線圈組結構定義一種線圈外型，此線圈外型具有兩垂直方向作用邊與兩軸向非作用邊，兩垂直方向作用邊之間距(CIW)、垂直方向作用邊的寬度(CSW)與線圈組的電流相位數量(#Φ)具有一特定公式，此特定公式為CIW=CSW×(#Φ-1)。藉由此線圈外型，使線圈能緊密重疊排列，以此減少線圈組所占空間，並增加線性馬達的效率。 In another U.S. Patent No. 5,998,890, a coil assembly structure for a coreless linear motor is proposed. The coil assembly structure defines a coil profile having two perpendicularly acting sides and two axially inactive sides, two perpendicular The direction-to-edge spacing (CIW), the width of the active side (CSW) in the vertical direction, and the number of current phases (#Φ) of the coil group have a specific formula, which is CIW=CSW×(#Φ-1). By virtue of the coil shape, the coils can be closely arranged to reduce the space occupied by the coil group and increase the efficiency of the linear motor.
但隨著近來線性馬達需要越來越大的馬達出力與運行速度，故線性馬達將通入更大的電流或使用更大的電壓。但此舉會讓線圈產生更大的熱量導致馬達效率變差，再加上無鐵心式線性馬達的線圈排列越來越緊密，以至於線圈產生的熱量越來越難排出。此外，使用更大的電流或電壓於越來越緊密的線圈中，將更進一步降低線圈間的絕緣效果，更甚將導致線圈短路等種種危險。上述的美國專利編號US5998890案，其揭露的CIW=CSW×(#Φ-1)特徵，使得線圈在緊密重疊排列後，並無額外的空間可供安裝散熱或絕緣元件，因此其散熱及絕緣效果並不理想。 But as linear motors have recently required larger and larger motor outputs and operating speeds, linear motors will draw larger currents or use larger voltages. However, this will cause the coil to generate more heat and cause the motor efficiency to deteriorate. In addition, the coil arrangement of the ironless linear motor becomes more and more tight, so that the heat generated by the coil is more and more difficult to discharge. In addition, the use of larger currents or voltages in increasingly tighter coils will further reduce the insulation between the coils, and will even lead to various risks such as coil shorts. The above-mentioned U.S. Patent No. 5,998,890 discloses a CIW=CSW×(#Φ-1) feature, so that after the coils are closely arranged, there is no additional space for mounting heat dissipation or insulation components, so the heat dissipation and insulation effects thereof. Not ideal.
