堆疊壓電陶瓷也叫疊層式微位移壓電陶瓷或多層堆疊式壓電陶瓷微動裝置，可用于微觀定位、閥門控制、減震及聲波的產生。壓電陶瓷微動器作為機電換能器能將電信號轉換成機械位移并應用于調節控制系統，多層堆疊結構壓電陶瓷具有體積小、位移分辨率極高、響應速度快、低電壓驅動、輸出力大。Aigtek安泰電子ATA-P系列壓(ya)電(dian)(dian)疊堆放(fang)大器在壓(ya)電(dian)(dian)陶瓷促動器的驅(qu)動中發揮(hui)著重要作用(yong)，今(jin)天我們就來一起了解一下該系統。

　　壓(ya)電(dian)陶(tao)(tao)瓷(ci)促動器是將疊堆式壓(ya)電(dian)陶(tao)(tao)瓷(ci)進行(xing)機構設計，與柔性(xing)鉸鏈支撐結構及外殼(ke)結構組(zu)合(he)成(cheng)一(yi)體結構，形成(cheng)封裝式壓(ya)電(dian)陶(tao)(tao)瓷(ci)促動器，使得(de)它可(ke)具有微位移分辨率高(gao)、穩定性(xing)強，同(tong)時彌補了疊堆壓(ya)電(dian)陶(tao)(tao)瓷(ci)不(bu)能承受(shou)拉(la)力的缺點，從(cong)而更適(shi)用于其他惡劣環境。

　　從驅(qu)動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)上的(de)不(bu)同，壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)陶(tao)(tao)(tao)瓷(ci)(ci)促動(dong)(dong)(dong)器(qi)可(ke)分為(wei)高壓(ya)(ya)(ya)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)陶(tao)(tao)(tao)瓷(ci)(ci)促動(dong)(dong)(dong)器(qi)與低(di)(di)壓(ya)(ya)(ya)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)陶(tao)(tao)(tao)瓷(ci)(ci)促動(dong)(dong)(dong)器(qi)，高壓(ya)(ya)(ya)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)陶(tao)(tao)(tao)瓷(ci)(ci)促動(dong)(dong)(dong)器(qi)內部由高壓(ya)(ya)(ya)疊(die)堆壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)陶(tao)(tao)(tao)瓷(ci)(ci)驅(qu)動(dong)(dong)(dong)，低(di)(di)壓(ya)(ya)(ya)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)陶(tao)(tao)(tao)瓷(ci)(ci)促動(dong)(dong)(dong)器(qi)內部由低(di)(di)壓(ya)(ya)(ya)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)陶(tao)(tao)(tao)瓷(ci)(ci)驅(qu)動(dong)(dong)(dong)。低(di)(di)壓(ya)(ya)(ya)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)陶(tao)(tao)(tao)瓷(ci)(ci)的(de)驅(qu)動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)一(yi)般(ban)為(wei)150V左(zuo)右(you)，高壓(ya)(ya)(ya)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)陶(tao)(tao)(tao)瓷(ci)(ci)的(de)驅(qu)動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)一(yi)般(ban)可(ke)達(da)500V或1000V；高壓(ya)(ya)(ya)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)陶(tao)(tao)(tao)瓷(ci)(ci)具有更低(di)(di)的(de)靜電(dian)(dian)(dian)(dian)容量，且出力一(yi)般(ban)比(bi)低(di)(di)壓(ya)(ya)(ya)的(de)高很多。
