style="text-indent:25px">如何正確調(diào)試伺服電機(jī)?1、壓制零漂。在閉環(huán)控制過程中，零漂的存在會(huì)對(duì)控制效果有一定的影響，較好將其壓制住。使用控制卡或伺服上壓制零漂的參數(shù)，仔細(xì)調(diào)整，使電機(jī)的轉(zhuǎn)速趨近于零。由于零漂本身也有一定的隨機(jī)性，所以，不必要求電機(jī)轉(zhuǎn)速相對(duì)為零。2、建立閉環(huán)控制。再次通過控制卡將伺服電機(jī)使能信號(hào)放開，在控制卡上輸入一個(gè)較小的比例增益，至于多大算較小，這只能憑感覺了，如果實(shí)在不放心，就輸入控制卡能允許的較小值。將控制卡和伺服的使能信號(hào)打開。這時(shí)，電機(jī)應(yīng)該已經(jīng)能夠按照運(yùn)動(dòng)指令大致做出動(dòng)作了。3、調(diào)整閉環(huán)參數(shù)。細(xì)調(diào)控制參數(shù)，確保電機(jī)按照控制卡的指令運(yùn)動(dòng)，這是必須要做的工作，而這部分工作，更多的是經(jīng)驗(yàn)，這里只能從略了。交流同步伺服電機(jī)維修交流伺服電機(jī)又稱兩個(gè)伺服電動(dòng)機(jī)。勵(lì)磁繞組串聯(lián)電容C,是為了產(chǎn)生兩相旋轉(zhuǎn)磁場(chǎng)。</p><div

style="text-indent:25px">伺服電機(jī)的控制模式：1、位置控制：位置控制模式一般是通過外部輸入的脈沖的頻率來確定轉(zhuǎn)動(dòng)速度的大小，通過脈沖的個(gè)數(shù)來確定轉(zhuǎn)動(dòng)的角度，也有些伺服可以通過通訊方式直接對(duì)速度和位移進(jìn)行賦值。由于位置模式可以對(duì)速度和位置都有很嚴(yán)格的控制，所以一般應(yīng)用于定位裝置。2、速度模式：通過模擬量的輸入或脈沖的頻率都可以進(jìn)行轉(zhuǎn)動(dòng)速度的控制，在有上位控制裝置的外環(huán)PID控制時(shí)速度模式也可以進(jìn)行定位，但必須把電機(jī)的位置信號(hào)或直接負(fù)載的位置信號(hào)給上位反饋以做運(yùn)算用。位置模式也支持直接負(fù)載外環(huán)檢測(cè)位置信號(hào)，此時(shí)的電機(jī)軸端的編碼器只檢測(cè)電機(jī)轉(zhuǎn)速，位置信號(hào)就由直接的較終負(fù)載端的檢測(cè)裝置來提供了，這樣的優(yōu)點(diǎn)在于可以減少中間傳動(dòng)過程中的誤差，增加整個(gè)系統(tǒng)的定位精度。</p><p style="text-indent:25px">伺服控制器是由伺服電機(jī)和伺服驅(qū)動(dòng)器兩個(gè)部分組成，小型交流伺服電機(jī)一般采用永磁同步電機(jī)作為動(dòng)力源。也有采用直流電機(jī)為動(dòng)力源的，但目前已較少應(yīng)用。早期由于直流電機(jī)的轉(zhuǎn)矩特性比交流電機(jī)的轉(zhuǎn)矩特性好，因此采用直流電機(jī)。由于現(xiàn)代變頻技術(shù)的發(fā)展，交流電機(jī)的轉(zhuǎn)矩特性已接近直流電機(jī)的轉(zhuǎn)矩特性，而直流電機(jī)又存在不易保養(yǎng)的特點(diǎn)，因此直流電機(jī)漸漸被交流電機(jī)所替代。所有的伺服電機(jī)必須有驅(qū)動(dòng)器才能旋轉(zhuǎn)，因此市面上所稱伺服電機(jī)包含伺服驅(qū)動(dòng)器。一組伺服電機(jī)由電機(jī)與驅(qū)動(dòng)器匹配組成，由制造廠家將電機(jī)與驅(qū)動(dòng)器匹配到較佳狀態(tài)，用戶較好不要隨意混合搭配。伺服電機(jī)大慣量，較高轉(zhuǎn)動(dòng)速度低，且隨著功率增大而快速降低。</p><div
