對(duì)于無(wú)刷直流電機(jī)，調(diào)速的時(shí)候表面上只控制了輸入電壓，但電機(jī)的自控變頻調(diào)速系統(tǒng)（無(wú)刷直流電機(jī)本身自帶轉(zhuǎn)子位置檢測(cè)器等轉(zhuǎn)子位置信號(hào)獲取裝置，使用此裝置的轉(zhuǎn)子位置信號(hào)來(lái)控制變壓變頻調(diào)速裝置的換相時(shí)刻）自動(dòng)根據(jù)變壓控制了頻率，用起來(lái)和直流（有刷）電機(jī)幾乎一樣，非常方便。 由于轉(zhuǎn)子采用永磁體，不需要專(zhuān)門(mén)的勵(lì)磁繞組，在同等容量的情況下，電機(jī)體積更小，重量更輕，效率更高，結(jié)構(gòu)更緊湊，運(yùn)行更可靠，動(dòng)態(tài)性能，在電動(dòng)汽車(chē)的驅(qū)動(dòng)等方面都獲得了廣泛的應(yīng)用。

三相交流電機(jī)——異步電機(jī)

交流電機(jī)分為同步電機(jī)和異步電機(jī)，同步電機(jī)多用于發(fā)電機(jī)，異步電機(jī)多用于電動(dòng)機(jī)。 電機(jī)的外殼是定子，定子上有三相對(duì)稱(chēng)交流繞組，由于三相電順序變化，形成一個(gè)旋轉(zhuǎn)的合成磁場(chǎng)，磁場(chǎng)的旋轉(zhuǎn)速度就是同步轉(zhuǎn)速。 同步轉(zhuǎn)速n=60f/p，f是頻率，p是極對(duì)數(shù)，比如對(duì)于接入國(guó)家電網(wǎng)50Hz的2極電動(dòng)機(jī)（即極對(duì)數(shù)為1對(duì)），那么轉(zhuǎn)速n=60*50/1=3000r/min。 同理，4極，6極，8極電機(jī)同步轉(zhuǎn)速為1500，1000,750  。 異步電機(jī)機(jī)構(gòu)簡(jiǎn)單，轉(zhuǎn)子為閉合線圈，比如鼠籠式。 轉(zhuǎn)子線圈將切割旋轉(zhuǎn)磁場(chǎng)，產(chǎn)生感應(yīng)電動(dòng)勢(shì)，進(jìn)而產(chǎn)生感應(yīng)電流，后產(chǎn)生旋轉(zhuǎn)磁場(chǎng)，這樣轉(zhuǎn)子就變成了一個(gè)電磁鐵，將跟隨定子磁場(chǎng)旋轉(zhuǎn)，所以轉(zhuǎn)子的轉(zhuǎn)速必然＜定子的旋轉(zhuǎn)磁場(chǎng)，這樣才能切割磁感線。 即轉(zhuǎn)子的異步轉(zhuǎn)速＜同步轉(zhuǎn)速，轉(zhuǎn)子與定子磁場(chǎng)存在轉(zhuǎn)速差，所以稱(chēng)之為異步電機(jī)。 不同廠家生產(chǎn)的異步電機(jī)額定轉(zhuǎn)速略有差異，2極電機(jī)約2800+r/min，4極，6極，8極異步約為1400+,950+,700+。 異步電機(jī)空載時(shí)轉(zhuǎn)速高，有負(fù)載時(shí)轉(zhuǎn)速下降。 異步電動(dòng)機(jī)結(jié)構(gòu)簡(jiǎn)單，維護(hù)方便，運(yùn)行可靠?jī)r(jià)格便宜，得到廣泛應(yīng)用。
