　　那么，還有什么是有待更進(jìn)一步的呢？盡管電機(jī)業(yè)對(duì)無(wú)刷電機(jī)優(yōu)勢(shì)的認(rèn)識(shí)日益加深，但迄今工作仍只限于開發(fā)上述的無(wú)刷電機(jī)霍爾傳感器控制電子元件。
　　目前對(duì)電機(jī)驅(qū)動(dòng)盒和電機(jī)驅(qū)動(dòng)卡開發(fā)的需求十分急迫，它們能為設(shè)計(jì)人員提供微控制器、可編程能力和驅(qū)動(dòng)器，并把所有這些功能都集成在一個(gè)單一封裝內(nèi)。不論是在數(shù)字還是模擬模式下，本質(zhì)上是這種集成方式完成各種電機(jī)應(yīng)用必需的換向。沒有這種集成，無(wú)刷電機(jī)就不起作用。
　　在選擇驅(qū)動(dòng)器時(shí)，脈寬調(diào)制(PWM)IC正逐漸作為一種技術(shù)受到認(rèn)可。驅(qū)動(dòng)器的選擇僅取決于效率。線性電路的缺點(diǎn)在中端開始突顯，此時(shí)輸出電平為50%左右。在這種輸出電平時(shí)，旁路元件的阻抗等于負(fù)載阻抗，這意味著放大器產(chǎn)生的熱量等于供給負(fù)載的功率！簡(jiǎn)言之，當(dāng)以中等功率等級(jí)驅(qū)動(dòng)電阻式負(fù)載時(shí)，線性控制電路出現(xiàn)50%的效率。
　　現(xiàn)在讓我們考慮一個(gè)PWM解決方案。在PWM控制系統(tǒng)中，模擬輸入電平被轉(zhuǎn)換為可變占空比開關(guān)驅(qū)動(dòng)信號(hào)。從一個(gè)電氣狀態(tài)切換到另一個(gè)狀態(tài)的過(guò)程，也就是OFF和ON之間的變化，被稱為“調(diào)制”，這也是這項(xiàng)技術(shù)被稱為“脈寬調(diào)制”的原因。剛開始占空比為零，即一直處于OFF狀態(tài)，當(dāng)電機(jī)開始旋轉(zhuǎn)時(shí)，占空比通常隨之增加，直至電機(jī)達(dá)到應(yīng)用所需的速度和/或轉(zhuǎn)矩為止。問(wèn)題仍然是，還有什么是有待更進(jìn)一步的呢？

直流無(wú)刷電機(jī)-無(wú)刷直流電機(jī)應(yīng)用
　　無(wú)刷直流電機(jī)的應(yīng)用十分廣泛，如汽車、工具、工業(yè)工控、自動(dòng)化以及航天等等。總的來(lái)說(shuō)，無(wú)刷直流電機(jī)可以分為以下三種主要用途：
　　持續(xù)負(fù)載應(yīng)用：主要是需要一定轉(zhuǎn)速但是對(duì)轉(zhuǎn)速精度要求不高的領(lǐng)域，比如風(fēng)扇、抽水機(jī)、吹風(fēng)機(jī)等一類的應(yīng)用，這類應(yīng)用成本較低且多為開環(huán)控制。
　　可變負(fù)載應(yīng)用：主要是轉(zhuǎn)速需要在某個(gè)范圍內(nèi)變化的應(yīng)用，對(duì)電機(jī)轉(zhuǎn)速特性和動(dòng)態(tài)響應(yīng)時(shí)間特性有更高的需求。如家用器具中的、甩干機(jī)和壓縮機(jī)就是很好的例子，汽車工業(yè)領(lǐng)域中的油泵控制、電控制器、發(fā)動(dòng)機(jī)控制等，這類應(yīng)用的系統(tǒng)成本相對(duì)更高些。
　　定位應(yīng)用：大多數(shù)工業(yè)控制和自動(dòng)控制方面的應(yīng)用屬于這個(gè)類別，這類應(yīng)用中往往會(huì)完成能量的輸送，所以對(duì)轉(zhuǎn)速的動(dòng)態(tài)響應(yīng)和轉(zhuǎn)矩有特別的要求，對(duì)控制器的要求也較高。測(cè)速時(shí)可能會(huì)用上光電和一些同步設(shè)備。過(guò)程控制、機(jī)械控制和運(yùn)輸控制等很多都屬于這類應(yīng)用。
