四輪電動車的主要部件

電(dian)機

電(dian)(dian)(dian)(dian)動(dong)車輛(liang)行駛由(you)電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)驅動(dong)而(er)完成，電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)有(you)直(zhi)(zhi)流電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)、交流電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)等類型。直(zhi)(zhi)流有(you)刷(shua)電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)由(you)磁場線圈(quan)、電(dian)(dian)(dian)(dian)樞線圈(quan)、電(dian)(dian)(dian)(dian)刷(shua)及(ji)刷(shua)架組成。磁場線圈(quan)通電(dian)(dian)(dian)(dian)以后(hou)產生磁場，電(dian)(dian)(dian)(dian)樞線圈(quan)在磁場下(xia)受(shou)力轉動(dong)，如果定(ding)子(zi)線圈(quan)和轉子(zi)線圈(quan)串聯在一起，即(ji)構成串勵電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)。如果電(dian)(dian)(dian)(dian)子(zi)線圈(quan)和轉子(zi)線圈(quan)并聯在一起，即(ji)成為并勵電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)。定(ding)子(zi)線圈(quan)和轉子(zi)互(hu)不相(xiang)連，定(ding)子(zi)線圈(quan)

由另外的(de)電源供電即(ji)稱(cheng)為(wei)他勵電機。

 一般(ban)來說(shuo)電(dian)動觀光車(che)上用(yong)直流串勵電(dian)機較多，電(dian)動高爾夫(fu)用(yong)他勵單機較多。
