style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;">　　什么是伺服電機和步進電機？</span></div><div><span style="font-size: 16px;">　　1、伺服電機：又稱施行電動機，在主動節(jié)制系統(tǒng)中，用作施行元件，把所收到的電信號轉(zhuǎn)換成電動機軸上的角位移或角速度輸出。分為直流和交換伺服電動機兩大類，其次要特點是，當(dāng)信號電壓為零時無自轉(zhuǎn)現(xiàn)象，轉(zhuǎn)速跟著轉(zhuǎn)矩的添加而勻速下降。伺服次要靠脈沖來定位，根基上能夠如許理解，西門子伺服電機領(lǐng)受到1個脈沖，就會扭轉(zhuǎn)1個脈沖對應(yīng)的角度，從而實現(xiàn)位移，由于，西門子伺服電機本身具備發(fā)出脈沖的功能，所以西門子伺服電機每扭轉(zhuǎn)一個角度，城市發(fā)出對應(yīng)數(shù)量的脈沖，如許，和西門子伺服電機接管的脈沖構(gòu)成了呼應(yīng)，或者叫閉環(huán)，如斯一來，系統(tǒng)就會曉得發(fā)了幾多脈沖給西門子伺服電機，同時又收了幾多脈沖回來，如許，就可以或許很切確的節(jié)制電機的動彈，從而實現(xiàn)切確的定位，能夠達到0.001mm。</span></div><div><span style="font-size: 16px;">　　2、步進電機：是一種離散活動的安裝，它和現(xiàn)代數(shù)字節(jié)制手藝有著素質(zhì)的聯(lián)系。在目前國內(nèi)的數(shù)字節(jié)制系統(tǒng)中，步進電機的使用十分普遍。跟著全數(shù)字式交換伺服系統(tǒng)的呈現(xiàn)，交換西門子伺服電機也越來越多地使用于數(shù)字節(jié)制系統(tǒng)中。為了順應(yīng)數(shù)字節(jié)制的成長趨向，活動節(jié)制系統(tǒng)中大多采用步進電機或全數(shù)字式交換西門子伺服電機作為施行電動機。雖然兩者在節(jié)制體例上類似彈性聯(lián)軸器，但在利用機能和使用場所上具有著較大的差別?，F(xiàn)就二者的利用機能作一比力。</span></div><div><span style="font-size: 16px;"><br /></span></div><p align="center"><span style="font-size: 16px;"><img src="https://img67.chem17.com/9/20220719/637938380748400469890.jpg" width="520" height="443" align="middle" alt="" /></span></p><p><span style="font-size: 16px;"> </span></p><div><span style="font-size: 16px;">　　西門子伺服電機和步進電機的區(qū)分：</span></div><div><span style="font-size: 16px;">　　1、低頻特征分歧：</span></div><div><span style="font-size: 16px;">　　步進電機在低速時易呈現(xiàn)低頻振動現(xiàn)象。振動頻次與負(fù)載環(huán)境和驅(qū)動器機能相關(guān)，一般認(rèn)為振動頻次為電機空載起跳頻次的一半。這種由步進電機的工作道理所決定的低頻振動現(xiàn)象對于機械的一般運轉(zhuǎn)很是晦氣。當(dāng)步進電機工作在低速時，一般應(yīng)采用阻尼手藝來降服低頻振動現(xiàn)象，好比在電機上加阻尼器，或驅(qū)動器上采用細(xì)分手藝等。</span></div><div><span style="font-size: 16px;">　　西門子伺服電機運轉(zhuǎn)很是平穩(wěn)膜片聯(lián)軸器，即便在低速時也不會呈現(xiàn)振動現(xiàn)象。交換伺服系統(tǒng)具有共振功能，可涵蓋機械的剛性不足，而且系統(tǒng)內(nèi)部具有頻次解析機能（FFT），可檢測出機械的共振點，便于系統(tǒng)調(diào)整。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;">　　2、矩頻特征分歧：</span></div><div><span style="font-size: 16px;">　　步進電機的輸出力矩隨轉(zhuǎn)速升高而下降，且在較高轉(zhuǎn)速時會急劇下降，所以其最高工作轉(zhuǎn)速一般在300～600RPM。西門子伺服電機為恒力矩輸出，即在其額定轉(zhuǎn)速以內(nèi)，都能輸出額定轉(zhuǎn)矩，在額定轉(zhuǎn)速以上為恒功率輸出。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;">　　3、過載能力分歧：</span></div><div><span style="font-size: 16px;">　　步進電機一般不具有過載能力。西門子伺服電機具有較強的過載能力。以松下交換伺服系統(tǒng)為例，它具有速渡過載和轉(zhuǎn)矩過載能力。其最大轉(zhuǎn)矩為額定轉(zhuǎn)矩的三倍，可用于降服慣性負(fù)載在啟動霎時的慣性力矩。步進電機由于沒有這種過載能力，在選型時為了降服這種慣性力矩，往往需要拔取較大轉(zhuǎn)矩的電機，而機械在一般工作期間又不需要那么大的轉(zhuǎn)矩，便呈現(xiàn)了力矩華侈的現(xiàn)象。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;">　　4、運轉(zhuǎn)機能分歧：</span></div><div><span style="font-size: 16px;">　　步進電機的節(jié)制為開環(huán)節(jié)制，啟動頻次過高或負(fù)載過大易呈現(xiàn)丟步或堵轉(zhuǎn)的現(xiàn)象，遏制時轉(zhuǎn)速過高易呈現(xiàn)過沖的現(xiàn)象，所認(rèn)為其節(jié)制精度，應(yīng)處置好升、降速問題。交換伺服驅(qū)動系統(tǒng)為閉環(huán)節(jié)制，驅(qū)動器可間接對電機編碼器反饋信號進行采樣，內(nèi)部形成環(huán)和速度環(huán)，一般不會呈現(xiàn)步進電機的丟步或過沖的現(xiàn)象，節(jié)制機能更為靠得住。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;">　　5、速度響應(yīng)機能分歧：</span></div><div><span style="font-size: 16px;">　　步進電機從靜止加快到工作轉(zhuǎn)速需要200～400毫秒。交換伺服系統(tǒng)的加快機能較好，以西門子伺服電機為例，從靜止加快到其額定轉(zhuǎn)速3000RPM僅需幾毫秒，可用于要求快速啟停的節(jié)制場所。</span></div> </div> <div id="5rbjpr1" class="ny_PrevNext"> <ul> <li>上一篇：<a
