style="text-indent:25px">現(xiàn)代電機(jī)通常都是高速運(yùn)轉(zhuǎn)的，它的運(yùn)轉(zhuǎn)速度每分鐘能夠達(dá)到數(shù)百甚至數(shù)千轉(zhuǎn)，這樣高的運(yùn)轉(zhuǎn)速度要進(jìn)行高低速的變換是相對(duì)困難的，但是很多應(yīng)用場(chǎng)合恰恰就有這樣的需求。因此，就需要現(xiàn)代電機(jī)為其提供轉(zhuǎn)換轉(zhuǎn)速的配件系統(tǒng)。但是這樣的轉(zhuǎn)換系統(tǒng)必然會(huì)增加整個(gè)電機(jī)系統(tǒng)的大小，并且也會(huì)影響到設(shè)備的精確度和工作效率。這時(shí)候，只有使現(xiàn)代電機(jī)驅(qū)動(dòng)向直接驅(qū)動(dòng)發(fā)展，才能有效的解決這一問(wèn)題?，F(xiàn)代工業(yè)的發(fā)展經(jīng)常需要電機(jī)的極速化，即經(jīng)常需要電機(jī)保持極高或者極低的速度。現(xiàn)代電機(jī)要極速化的要求與電機(jī)的直驅(qū)化緊密相關(guān)。電機(jī)的極速化，不僅有助于實(shí)現(xiàn)電機(jī)的直驅(qū)化，而且可以提高電機(jī)的工作效率和設(shè)備的精確度。</p><div
