電(dian)(dian)(dian)機(ji)(ji)的(de)重(zhong)(zhong)(zhong)量(liang)(liang)(liang)(liang)與動(dong)力輸出需(xu)(xu)(xu)要(yao)合(he)理平衡，這直接影響電(dian)(dian)(dian)助力自行(xing)車的(de)騎(qi)(qi)行(xing)體驗(yan)。在(zai)相同(tong)功率下，電(dian)(dian)(dian)機(ji)(ji)重(zhong)(zhong)(zhong)量(liang)(liang)(liang)(liang)越(yue)輕，車輛的(de)整(zheng)體負(fu)載(zai)越(yue)小，騎(qi)(qi)行(xing)時(shi)的(de)靈活性和操控(kong)性越(yue)好，尤其(qi)在(zai)需(xu)(xu)(xu)要(yao)人(ren)力輔助的(de)場景中(zhong)，輕量(liang)(liang)(liang)(liang)化(hua)(hua)電(dian)(dian)(dian)機(ji)(ji)能(neng)(neng)減少額(e)外負(fu)擔。但動(dong)力輸出的(de)提升往往需(xu)(xu)(xu)要(yao)更(geng)大的(de)磁鋼體積或更(geng)多的(de)繞組匝(za)數(shu)，這會增加電(dian)(dian)(dian)機(ji)(ji)重(zhong)(zhong)(zhong)量(liang)(liang)(liang)(liang)，因(yin)此(ci)設計時(shi)需(xu)(xu)(xu)在(zai)兩者(zhe)之間尋找(zhao)平衡點。例如，通(tong)勤用電(dian)(dian)(dian)機(ji)(ji)通(tong)常在(zai)保(bao)證基礎動(dong)力的(de)前提下優先控(kong)制重(zhong)(zhong)(zhong)量(liang)(liang)(liang)(liang)，采用小型化(hua)(hua)磁鋼和精簡結構(gou)；而山地用電(dian)(dian)(dian)機(ji)(ji)為(wei)滿(man)足爬坡(po)和載(zai)重(zhong)(zhong)(zhong)需(xu)(xu)(xu)求，會適當增加重(zhong)(zhong)(zhong)量(liang)(liang)(liang)(liang)以提升扭(niu)矩(ju)輸出。材(cai)料(liao)選擇對平衡兩者(zhe)關系至關重(zhong)(zhong)(zhong)要(yao)，采用強度高的(de)鋁合(he)金(jin)或工程塑料(liao)作為(wei)外殼材(cai)料(liao)，能(neng)(neng)在(zai)保(bao)證結構(gou)強度的(de)同(tong)時(shi)減輕重(zhong)(zhong)(zhong)量(liang)(liang)(liang)(liang)；優化(hua)(hua)內部(bu)繞組布局，使用細直徑(jing)高導電(dian)(dian)(dian)銅線，可在(zai)減少體積的(de)情況下維持動(dong)力輸出，實(shi)現輕量(liang)(liang)(liang)(liang)化(hua)(hua)與高動(dong)力的(de)兼顧。石家莊電(dian)(dian)(dian)動(dong)車馬(ma)達故障購買國(guo)產自行(xing)車電(dian)(dian)(dian)機(ji)(ji)請找(zhao)常州(zhou)橙易新能(neng)(neng)源科(ke)技有限公司。

自行車(che)電(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)(de)工作原理(li)基于電(dian)(dian)(dian)磁(ci)感(gan)應定(ding)律，通(tong)過(guo)電(dian)(dian)(dian)能轉化為機(ji)(ji)(ji)械能驅動車(che)輪轉動。以(yi)無(wu)刷(shua)直(zhi)流電(dian)(dian)(dian)機(ji)(ji)(ji)為例(li)，其內部包含定(ding)子和(he)轉子，定(ding)子上繞(rao)有(you)線圈(quan)，轉子則由(you)永磁(ci)體構成。當電(dian)(dian)(dian)流通(tong)過(guo)定(ding)子線圈(quan)時，會產生旋轉磁(ci)場，與轉子的(de)(de)(de)永磁(ci)體相互作用，產生電(dian)(dian)(dian)磁(ci)轉矩，帶(dai)(dai)動轉子轉動，進而通(tong)過(guo)傳動機(ji)(ji)(ji)構帶(dai)(dai)動車(che)輪旋轉。在電(dian)(dian)(dian)助(zhu)力(li)自行車(che)中，電(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)(de)工作狀態受控(kong)制(zhi)器(qi)和(he)傳感(gan)器(qi)調控(kong)，當騎行者踩(cai)著(zhu)踏板時，傳感(gan)器(qi)檢測到踩(cai)的(de)(de)(de)力(li)度或頻率，將(jiang)信(xin)號傳遞給控(kong)制(zhi)器(qi)，控(kong)制(zhi)器(qi)根據預設(she)程序調整輸入電(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)(de)電(dian)(dian)(dian)流大小，從而改變電(dian)(dian)(dian)機(ji)(ji)(ji)輸出(chu)的(de)(de)(de)助(zhu)力(li)強(qiang)度，實(shi)現(xian)人力(li)與電(dian)(dian)(dian)力(li)的(de)(de)(de)協同工作。
