四輪電動車的主要部件

電機

電(dian)(dian)動車輛(liang)行(xing)駛由電(dian)(dian)動機(ji)(ji)(ji)驅動而完成，電(dian)(dian)機(ji)(ji)(ji)有(you)直流電(dian)(dian)動機(ji)(ji)(ji)、交流電(dian)(dian)動機(ji)(ji)(ji)等類型。直流有(you)刷(shua)電(dian)(dian)動機(ji)(ji)(ji)由磁場(chang)線(xian)圈(quan)(quan)(quan)(quan)、電(dian)(dian)樞線(xian)圈(quan)(quan)(quan)(quan)、電(dian)(dian)刷(shua)及刷(shua)架組成。磁場(chang)線(xian)圈(quan)(quan)(quan)(quan)通(tong)電(dian)(dian)以后產生(sheng)磁場(chang)，電(dian)(dian)樞線(xian)圈(quan)(quan)(quan)(quan)在(zai)(zai)磁場(chang)下受力轉(zhuan)(zhuan)動，如果定(ding)子(zi)(zi)線(xian)圈(quan)(quan)(quan)(quan)和(he)轉(zhuan)(zhuan)子(zi)(zi)線(xian)圈(quan)(quan)(quan)(quan)串聯(lian)在(zai)(zai)一起(qi)，即構成串勵(li)電(dian)(dian)機(ji)(ji)(ji)。如果電(dian)(dian)子(zi)(zi)線(xian)圈(quan)(quan)(quan)(quan)和(he)轉(zhuan)(zhuan)子(zi)(zi)線(xian)圈(quan)(quan)(quan)(quan)并(bing)聯(lian)在(zai)(zai)一起(qi)，即成為并(bing)勵(li)電(dian)(dian)機(ji)(ji)(ji)。定(ding)子(zi)(zi)線(xian)圈(quan)(quan)(quan)(quan)和(he)轉(zhuan)(zhuan)子(zi)(zi)互不相連，定(ding)子(zi)(zi)線(xian)圈(quan)(quan)(quan)(quan)

由另外(wai)的電源供電即稱(cheng)為他勵電機。

 一般(ban)來說(shuo)電動觀光車(che)上用(yong)直流串勵電機較(jiao)多(duo)(duo)，電動高爾夫用(yong)他勵單機較(jiao)多(duo)(duo)。
