　　② 交流伺服電機(jī)也是無(wú)刷電機(jī)，分為同步和異步電機(jī)，目前運(yùn)動(dòng)控制中一般都用同步電機(jī)，它的功率范圍大，可以做到很大的功率。大慣量，轉(zhuǎn)動(dòng)速度低，且隨著功率增大而快速降低。因而適合做低速平穩(wěn)運(yùn)行的應(yīng)用。

　　③ 伺服電機(jī)內(nèi)部的轉(zhuǎn)子是永磁鐵，驅(qū)動(dòng)器控制的U/V/W三相電形成電磁場(chǎng)，轉(zhuǎn)子在此磁場(chǎng)的作用下轉(zhuǎn)動(dòng)，同時(shí)電機(jī)自帶的編碼器反饋信號(hào)給驅(qū)動(dòng)器，驅(qū)動(dòng)器根據(jù)反饋值與目標(biāo)值進(jìn)行比較，調(diào)整轉(zhuǎn)子轉(zhuǎn)動(dòng)的角度。伺服電機(jī)的精度決定于編碼器的精度（線數(shù)）。

　　特點(diǎn)：交流伺服電動(dòng)機(jī)定子的構(gòu)造基本上與電容分相式單相異步電動(dòng)機(jī)相似.其定子上裝有兩個(gè)位置互差90°的繞組，一個(gè)是勵(lì)磁繞組Rf，它始終接在交流電壓Uf上；另一個(gè)是控制繞組L，聯(lián)接控制信號(hào)電壓Uc。所以交流伺服電動(dòng)機(jī)又稱兩個(gè)伺服電動(dòng)機(jī)。

為保持鍋水的溫度，可利用其他鍋爐的蒸氣來(lái)加熱鍋水，當(dāng)單臺(tái)鍋爐在保養(yǎng)期間沒(méi)有蒸氣來(lái)源時(shí)，可定在爐膛內(nèi)生活維持。此法一般用于熱備用鍋爐或停爐時(shí)間不超過(guò)一周的鍋爐。濕法保養(yǎng)使法保養(yǎng)是利用一定濃度的堿性溶液于鍋爐內(nèi)表面金屬接觸，使金屬表面形成堿保護(hù)膜，來(lái)防止金屬的腐蝕。鍋爐停爐后，將鍋水放盡，清楚水垢和煙灰，關(guān)閉所有的入孔，手孔，閥門等，與其他運(yùn)行的鍋爐完全隔離。然后將軟化水制入注入鍋爐至水位，再用專用泵將配置好的堿性防腐液注入鍋爐。

齒輪減速機(jī)在使用過(guò)程中，出現(xiàn)減速機(jī)漏油問(wèn)題較為普遍。有些漏油比較嚴(yán)重的減速器，不僅會(huì)損失很多潤(rùn)滑油照成資源浪費(fèi)，而且對(duì)齒輪減速機(jī)本身及對(duì)周圍環(huán)境的清潔衛(wèi)生造成不好的影響，嚴(yán)重點(diǎn)可能還會(huì)影響工作的進(jìn)度。針對(duì)減速器漏油問(wèn)題我們進(jìn)行分析，找出問(wèn)題便可處理到位。
一、由于減速箱設(shè)計(jì)不合理，比如說(shuō)減速箱上沒(méi)有設(shè)計(jì)透氣孔或透氣孔太小，使減速器的內(nèi)部壓力大于外面壓力，導(dǎo)致潤(rùn)滑油外泄；也可能由于運(yùn)行機(jī)構(gòu)的減速器的油池是由上下箱體組成，因?yàn)殚L(zhǎng)時(shí)間的運(yùn)行震動(dòng)，兩箱體的連接面密封不嚴(yán)易漏油。
二、減速箱的材料制造設(shè)計(jì)達(dá)不到要求，箱體接合面精度不夠、材料密度不好等都會(huì)導(dǎo)致密封不嚴(yán)而產(chǎn)生滲油。
三、使用、維護(hù)不當(dāng)造成多處透氣孔洞堵塞，導(dǎo)致內(nèi)部壓力過(guò)高，油量過(guò)多，油位過(guò)高；連接螺栓松動(dòng)、密封圈腐蝕，使兩箱體的結(jié)合面不嚴(yán)實(shí)。
預(yù)防減速器漏油，必須嚴(yán)格按要求進(jìn)行，應(yīng)該改進(jìn)設(shè)計(jì)，在減速器透氣孔蓋和加油孔蓋上加設(shè)通氣裝置并保持通暢，保證箱體內(nèi)外壓力均衡氣流通順，使用環(huán)境良好等；可適當(dāng)提高兩箱體接合面和各配合面的加工精度，防止箱體變形；另外還要做好減速機(jī)的維護(hù)工作，經(jīng)常檢查和疏通減速器的通氣孔，油量適當(dāng)，檢修檢修箱體剖分面，變形嚴(yán)重則更換；清理回油槽、查看密封圈、緊固螺栓。
