無刷電機(jī)體積小，重量輕，出力大，響應(yīng)快，速度高，慣量小，轉(zhuǎn)動(dòng)平滑，力矩穩(wěn)定?？刂茝?fù)雜，容易實(shí)現(xiàn)智能化，其電子換相方式靈活，可以方波換相或正弦波換相。電機(jī)免維護(hù)，效率很高，運(yùn)行溫度低，電磁輻射很小，長(zhǎng)壽命，可用于各種環(huán)境。
2、交流伺服電機(jī)也是無刷電機(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)）。
交流伺服電機(jī)和無刷直流伺服電機(jī)在功能上的區(qū)別：交流伺服要好一些，因?yàn)槭钦也刂?，轉(zhuǎn)矩脈動(dòng)小。直流伺服是梯形波。但直流伺服比較簡(jiǎn)單，便宜。

為使TI元器件肯有盡可能好的性能和結(jié)構(gòu)、合理的工藝和較低的成本，在選用電子材料時(shí)，一般應(yīng)遵循以下的原則。根據(jù)TI元器件性能參數(shù)先用材料。不同的場(chǎng)合對(duì)電子元器件的性能有不同的要求，應(yīng)根據(jù)這些要求選擇所有材料（介質(zhì)材料、導(dǎo)電材料及包封材料等）根據(jù)元器件結(jié)構(gòu)特點(diǎn)選用材料。由于電子元器件用途各異，使用環(huán)境有很大差別，因此元器件的結(jié)構(gòu)方式各不相同。，在高溫度下使用的電容器和電阻器，需要進(jìn)行全密封結(jié)構(gòu)，這時(shí)除了選擇介質(zhì)材料、電阻材料之外，還要考慮合適的包封材料。
