換向器是一個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。在小容量電機中，氣隙為0.5～3mm。氣隙數(shù)值雖小，但磁阻很大，為電機磁路的主要組成部分。氣隙大小對電機運行性能有很大影響。

永磁直流無刷電機永磁直流無刷電動機的學名叫“無換向器電機”或“無整流子電機”，是一種的無級變速電機，它由一臺同步電機和一組逆變橋所組成，具有直流電機那樣良好的調(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)簡單，制造方便，不需要經(jīng)常性維護等優(yōu)點，是一種理想的變速電機。

直流電機具有響應(yīng)快速、起動轉(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。但直流電機的優(yōu)點也正是它的缺點，因為直流電機要產(chǎn)生額定負載下恒定轉(zhuǎn)矩，則電樞磁場與轉(zhuǎn)子磁場須恒維持90°，這就要藉由碳刷及整流子。碳刷及整流子在電機轉(zhuǎn)動時會產(chǎn)生火花、碳粉，除了會造成組件損壞之外，使用場合也受到限制。交流電機沒有碳刷及整流子，免維護、堅固、應(yīng)用廣，但特性上若要達到相當于直流電機的性能須用復雜控制技術(shù)才能達到�，F(xiàn)今半導體發(fā)展迅速功率組件切換頻率加快許多，提升了驅(qū)動電機的性能。
