Thorlabs的(de)(de)(de)(de)音(yin)(yin)圈(quan)電(dian)(dian)(dian)(dian)機適合(he)要求高(gao)速(su)或高(gao)加(jia)速(su)度定位的(de)(de)(de)(de)應用。這些直線音(yin)(yin)圈(quan)電(dian)(dian)(dian)(dian)機由線圈(quan)和磁(ci)(ci)體組成(cheng)，產生線性力(li)(li)(li)，同時避免了移動(dong)部分與(yu)固定部分之間的(de)(de)(de)(de)接觸。音(yin)(yin)圈(quan)電(dian)(dian)(dian)(dian)機將(jiang)電(dian)(dian)(dian)(dian)信號(hao)直接轉(zhuan)化成(cheng)線性磁(ci)(ci)力(li)(li)(li)，與(yu)需要皮帶或齒輪等(deng)單獨的(de)(de)(de)(de)傳動(dong)系統的(de)(de)(de)(de)DC電(dian)(dian)(dian)(dian)機相比，音(yin)(yin)圈(quan)電(dian)(dian)(dian)(dian)機可(ke)以提供(gong)更(geng)高(gao)純度的(de)(de)(de)(de)運動(dong)。與(yu)位置傳感器(qi)配合(he)使(shi)用時，音(yin)(yin)圈(quan)電(dian)(dian)(dian)(dian)機提供(gong)快速(su)準確的(de)(de)(de)(de)運動(dong)，且可(ke)重(zhong)復性高(gao)。電(dian)(dian)(dian)(dian)壓的(de)(de)(de)(de)極性決定了電(dian)(dian)(dian)(dian)機的(de)(de)(de)(de)移動(dong)方(fang)向(xiang)。如果(guo)將(jiang)紅線用于正(zheng)電(dian)(dian)(dian)(dian)壓，施加(jia)電(dian)(dian)(dian)(dian)流(liu)時磁(ci)(ci)體組件(jian)會伸(shen)出。雖然電(dian)(dian)(dian)(dian)機的(de)(de)(de)(de)位置也會影響電(dian)(dian)(dian)(dian)機提供(gong)的(de)(de)(de)(de)力(li)(li)(li)，但可(ke)以通過(guo)將(jiang)電(dian)(dian)(dian)(dian)流(liu)乘(cheng)以力(li)(li)(li)常(chang)數(shu)估(gu)算這個(ge)力(li)(li)(li)。

音(yin)(yin)圈(quan)電機兩端應該安(an)(an)裝(zhuang)牢(lao)固，這樣磁體組(zu)件(jian)(jian)(jian)(jian)就(jiu)會懸在音(yin)(yin)圈(quan)周圍而(er)避免接觸(chu)。VC063/M和VC125/M磁體組(zu)件(jian)(jian)(jian)(jian)的中心有(you)一(yi)個M3盲孔(kong)，而(er)線圈(quan)組(zu)件(jian)(jian)(jian)(jian)的中心是一(yi)個M3安(an)(an)裝(zhuang)孔(kong)。VC250/M、VC500/M和VC600/M磁體組(zu)件(jian)(jian)(jian)(jian)的中心有(you)一(yi)個M6盲孔(kong)，而(er)線圈(quan)組(zu)件(jian)(jian)(jian)(jian)的中心是一(yi)個Ø6.35 mm通(tong)孔(kong)，通(tong)孔(kong)兩邊各有(you)一(yi)個M4安(an)(an)裝(zhuang)孔(kong)。這些(xie)安(an)(an)裝(zhuang)孔(kong)可用于(yu)我們的直角(jiao)支架，以便(bian)將音(yin)(yin)圈(quan)電機的任(ren)一(yi)端固定(ding)在光(guang)(guang)學平臺或(huo)位移臺的移動部分(fen)。所有(you)型號的音(yin)(yin)圈(quan)電機都有(you)SM外螺(luo)紋，用于(yu)安(an)(an)裝(zhuang)固定(ding)式光(guang)(guang)學元件(jian)(jian)(jian)(jian)安(an)(an)裝(zhuang)座(zuo)或(huo)透(tou)鏡套(tao)管(guan)。

如果音(yin)圈電機的移動(dong)(dong)超過(guo)了建議(yi)的行程(cheng)范圍，則磁體組件(jian)可(ke)能會(hui)過(guo)度偏離線圈組件(jian)，從而無法維持適當的磁相互(hu)作用。在這(zhe)種情況(kuang)下，電機的響應可(ke)能不會(hui)如預期一樣，所以須(xu)手動(dong)(dong)調回組件(jian)。
