四輪電動車的主要部件

電機(ji)

電(dian)(dian)(dian)動(dong)(dong)(dong)車輛行駛由電(dian)(dian)(dian)動(dong)(dong)(dong)機驅動(dong)(dong)(dong)而完成(cheng)(cheng)，電(dian)(dian)(dian)機有直流(liu)(liu)電(dian)(dian)(dian)動(dong)(dong)(dong)機、交(jiao)流(liu)(liu)電(dian)(dian)(dian)動(dong)(dong)(dong)機等類型(xing)。直流(liu)(liu)有刷電(dian)(dian)(dian)動(dong)(dong)(dong)機由磁(ci)場(chang)(chang)線(xian)(xian)圈(quan)(quan)、電(dian)(dian)(dian)樞線(xian)(xian)圈(quan)(quan)、電(dian)(dian)(dian)刷及刷架組成(cheng)(cheng)。磁(ci)場(chang)(chang)線(xian)(xian)圈(quan)(quan)通電(dian)(dian)(dian)以后產(chan)生磁(ci)場(chang)(chang)，電(dian)(dian)(dian)樞線(xian)(xian)圈(quan)(quan)在磁(ci)場(chang)(chang)下受力轉動(dong)(dong)(dong)，如(ru)果定子(zi)線(xian)(xian)圈(quan)(quan)和轉子(zi)線(xian)(xian)圈(quan)(quan)串聯(lian)在一起(qi)，即構成(cheng)(cheng)串勵(li)電(dian)(dian)(dian)機。如(ru)果電(dian)(dian)(dian)子(zi)線(xian)(xian)圈(quan)(quan)和轉子(zi)線(xian)(xian)圈(quan)(quan)并聯(lian)在一起(qi)，即成(cheng)(cheng)為并勵(li)電(dian)(dian)(dian)機。定子(zi)線(xian)(xian)圈(quan)(quan)和轉子(zi)互不相連，定子(zi)線(xian)(xian)圈(quan)(quan)

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

 一般來說(shuo)電(dian)動(dong)觀光車上用直流串勵電(dian)機(ji)較多(duo)，電(dian)動(dong)高爾夫用他勵單(dan)機(ji)較多(duo)。
