四輪電動車的主要部件

電機

電(dian)(dian)動(dong)(dong)(dong)車輛行駛由(you)電(dian)(dian)動(dong)(dong)(dong)機(ji)驅(qu)動(dong)(dong)(dong)而完成(cheng)，電(dian)(dian)機(ji)有直流電(dian)(dian)動(dong)(dong)(dong)機(ji)、交流電(dian)(dian)動(dong)(dong)(dong)機(ji)等類(lei)型。直流有刷電(dian)(dian)動(dong)(dong)(dong)機(ji)由(you)磁(ci)場(chang)線(xian)圈(quan)、電(dian)(dian)樞(shu)線(xian)圈(quan)、電(dian)(dian)刷及刷架組(zu)成(cheng)。磁(ci)場(chang)線(xian)圈(quan)通電(dian)(dian)以后產生磁(ci)場(chang)，電(dian)(dian)樞(shu)線(xian)圈(quan)在磁(ci)場(chang)下(xia)受力轉(zhuan)動(dong)(dong)(dong)，如果定子線(xian)圈(quan)和轉(zhuan)子線(xian)圈(quan)串聯在一(yi)起(qi)，即構成(cheng)串勵電(dian)(dian)機(ji)。如果電(dian)(dian)子線(xian)圈(quan)和轉(zhuan)子線(xian)圈(quan)并聯在一(yi)起(qi)，即成(cheng)為并勵電(dian)(dian)機(ji)。定子線(xian)圈(quan)和轉(zhuan)子互不相連，定子線(xian)圈(quan)

由另外(wai)的電(dian)源供電(dian)即稱為他勵電(dian)機(ji)。

 一般(ban)來說電(dian)(dian)(dian)動觀光車上用直流串勵(li)電(dian)(dian)(dian)機較(jiao)多，電(dian)(dian)(dian)動高爾夫用他勵(li)單(dan)機較(jiao)多。
