換向器是一個(gè)由許多燕尾狀的梯形銅片間隔云母片絕緣排列而成的圓柱體，每片換向片的一端有高出的部分，上面銑有線槽，供電樞繞組引出端焊接用。所有換向片均放置在與它配合的具有燕尾狀槽的金屬套簡(jiǎn)內(nèi)，然后用V形鋼環(huán)和螺紋壓圈將換向片和套筒緊固成一整體，換向片組與套筒、V形鋼環(huán)之間均要用云母片絕緣。
（3）轉(zhuǎn)軸 在轉(zhuǎn)軸上安裝電樞和換向器。
3．氣隙
靜止的磁極和旋轉(zhuǎn)的電樞之間的間隙稱為氣隙。在小容量電機(jī)中，氣隙為0.5～3mm。氣隙數(shù)值雖小，但磁阻很大，為電機(jī)磁路的主要組成部分。氣隙大小對(duì)電機(jī)運(yùn)行性能有很大影響。

MI電纜具有良好的耐火特性且可以長(zhǎng)期工作在25℃高溫之下，同時(shí)還有防爆、耐腐蝕性強(qiáng)、載流量大、耐輻射、機(jī)械強(qiáng)度高、體積小、重量輕、壽命長(zhǎng)、無煙的特點(diǎn)。但價(jià)格貴、工藝復(fù)雜、施工難度大，在油灌區(qū)、重要木結(jié)構(gòu)公共建筑、高溫場(chǎng)所等耐火要求高且經(jīng)濟(jì)性可以接受的場(chǎng)合，可采用這種耐火性能好的電纜。用時(shí)注意的問題根據(jù)耐火電纜的具體特性，設(shè)計(jì)人員在設(shè)計(jì)選用時(shí)應(yīng)注意以下幾個(gè)問題：當(dāng)耐火電纜用于電纜密集的電纜隧道、電纜夾層中，或位于油管、油庫附近等易燃場(chǎng)所時(shí)，應(yīng)首先選用A類耐火電纜。

永磁直流無刷電機(jī)永磁直流無刷電動(dòng)機(jī)的學(xué)名叫“無換向器電機(jī)”或“無整流子電機(jī)”，是一種的無級(jí)變速電機(jī)，它由一臺(tái)同步電機(jī)和一組逆變橋所組成，具有直流電機(jī)那樣良好的調(diào)速特性，但是由於沒有換向器，因而可做成無接觸式，具有結(jié)構(gòu)簡(jiǎn)單，制造方便，不需要經(jīng)常性維護(hù)等優(yōu)點(diǎn)，是一種理想的變速電機(jī)。
直流電機(jī)具有響應(yīng)快速、起動(dòng)轉(zhuǎn)矩較大、從零轉(zhuǎn)速至額定轉(zhuǎn)速可提供額定轉(zhuǎn)矩的性能。但直流電機(jī)的優(yōu)點(diǎn)也正是它的缺點(diǎn)，因?yàn)橹绷麟姍C(jī)要產(chǎn)生額定負(fù)載下恒定轉(zhuǎn)矩，則電樞磁場(chǎng)與轉(zhuǎn)子磁場(chǎng)須恒維持90°，這就要藉由碳刷及整流子。碳刷及整流子在電機(jī)轉(zhuǎn)動(dòng)時(shí)會(huì)產(chǎn)生火花、碳粉，除了會(huì)造成組件損壞之外，使用場(chǎng)合也受到限制。交流電機(jī)沒有碳刷及整流子，免維護(hù)、堅(jiān)固、應(yīng)用廣，但特性上若要達(dá)到相當(dāng)于直流電機(jī)的性能須用復(fù)雜控制技術(shù)才能達(dá)到?，F(xiàn)今半導(dǎo)體發(fā)展迅速功率組件切換頻率加快許多，提升了驅(qū)動(dòng)電機(jī)的性能。
