驅動電機及電控由直流向交流方向發展。金昌叉車采用(yong)交流(liu)電(dian)控可以(yi)提(ti)高(gao)生(sheng)產率，加(jia)速(su)快，可提(ti)高(gao)車(che)輛行(xing)駛(shi)速(su)度和(he)門架起(qi)升(sheng)速(su)度，且高(gao)速(su)行(xing)駛(shi)時(shi)輸出轉(zhuan)矩大。在同樣(yang)工況下能耗小，可以(yi)延長(chang)蓄(xu)電(dian)池組單班使用(yong)時(shi)間(jian)。另外，交流(liu)電(dian)機無(wu)電(dian)刷和(he)換向器，不必定期維護，使整(zheng)個交流(liu)控制系統運(yun)行(xing)費用(yong)降低。

轉(zhuan)(zhuan)向(xiang)(xiang)(xiang)系統(tong)向(xiang)(xiang)(xiang)電子化邁(mai)進。傳統(tong)的(de)蓄(xu)電池叉車轉(zhuan)(zhuan)向(xiang)(xiang)(xiang)系統(tong)采用機(ji)械轉(zhuan)(zhuan)向(xiang)(xiang)(xiang)或液壓(ya)助力(li)轉(zhuan)(zhuan)向(xiang)(xiang)(xiang)。機(ji)械轉(zhuan)(zhuan)向(xiang)(xiang)(xiang)的(de)缺點是：操縱(zong)力(li)大，操作者易疲勞；而(er)液壓(ya)助力(li)轉(zhuan)(zhuan)向(xiang)(xiang)(xiang)的(de)缺點是浪費能量。采用電子轉(zhuan)(zhuan)向(xiang)(xiang)(xiang)不僅操縱(zong)力(li)小，而(er)且比液壓(ya)助力(li)轉(zhuan)(zhuan)向(xiang)(xiang)(xiang)節能約25%。

操(cao)縱(zong)系(xi)統向集成(cheng)(cheng)(cheng)化方向發(fa)展。隨著操(cao)作人(ren)員(yuan)對操(cao)縱(zong)舒適性的要求越來越高，集成(cheng)(cheng)(cheng)化操(cao)縱(zong)成(cheng)(cheng)(cheng)為發(fa)展趨勢。所(suo)謂集成(cheng)(cheng)(cheng)化操(cao)縱(zong)就(jiu)是(shi)用一個操(cao)縱(zong)手柄完成(cheng)(cheng)(cheng)蓄電池叉車的所(suo)有控制(zhi)動作：叉車前(qian)(qian)進/后(hou)退、門(men)架前(qian)(qian)移/后(hou)退、門(men)架上(shang)升/下降(jiang)、貨叉前(qian)(qian)傾/后(hou)傾、貨叉左側移/右側移。這樣，可降(jiang)低(di)操(cao)作人(ren)員(yuan)的勞動強度，從而提高勞動效率。

制(zhi)動(dong)(dong)(dong)(dong)系統(tong)向電(dian)子(zi)化方向發(fa)展(zhan)。為了(le)減(jian)少制(zhi)動(dong)(dong)(dong)(dong)沖擊，增強適用性，要(yao)求傳動(dong)(dong)(dong)(dong)系統(tong)的(de)(de)(de)制(zhi)動(dong)(dong)(dong)(dong)力(li)(li)(li)矩可(ke)(ke)調，從而(er)促進(jin)了(le)可(ke)(ke)調力(li)(li)(li)矩電(dian)磁制(zhi)動(dong)(dong)(dong)(dong)器(qi)的(de)(de)(de)發(fa)展(zhan)。可(ke)(ke)調力(li)(li)(li)矩制(zhi)動(dong)(dong)(dong)(dong)器(qi)由1個彈簧加(jia)壓制(zhi)動(dong)(dong)(dong)(dong)器(qi)和電(dian)子(zi)控制(zhi)裝置——力(li)(li)(li)矩控制(zhi)器(qi)組成，這種機電(dian)一體化的(de)(de)(de)制(zhi)動(dong)(dong)(dong)(dong)系統(tong)在(zai)實(shi)現制(zhi)動(dong)(dong)(dong)(dong)力(li)(li)(li)矩可(ke)(ke)調功能的(de)(de)(de)同時(shi)，還可(ke)(ke)以(yi)通過力(li)(li)(li)矩控制(zhi)器(qi)對(dui)制(zhi)動(dong)(dong)(dong)(dong)器(qi)的(de)(de)(de)磨(mo)損進(jin)行監測，使系統(tong)的(de)(de)(de)可(ke)(ke)靠(kao)性提高，降低運行維護(hu)成本。此外，這種可(ke)(ke)調力(li)(li)(li)矩制(zhi)動(dong)(dong)(dong)(dong)器(qi)還可(ke)(ke)以(yi)設置CAN總(zong)線(xian)接口(kou)，以(yi)實(shi)現對(dui)制(zhi)動(dong)(dong)(dong)(dong)器(qi)的(de)(de)(de)遠程(cheng)診(zhen)斷(duan)及(ji)控制(zhi)和對(dui)制(zhi)動(dong)(dong)(dong)(dong)控制(zhi)的(de)(de)(de)網絡化操作(zuo)。

液(ye)(ye)壓泵(beng)電(dian)(dian)機(ji)控(kong)制(zhi)(zhi)器的應用(yong)。液(ye)(ye)壓泵(beng)電(dian)(dian)機(ji)控(kong)制(zhi)(zhi)器可以(yi)控(kong)制(zhi)(zhi)電(dian)(dian)機(ji)實現(xian)門架起升/前(qian)進/后退等動作的無級(ji)調速，還可以(yi)設定電(dian)(dian)機(ji)轉速，以(yi)控(kong)制(zhi)(zhi)貨叉傾斜/側移速度。采用(yong)液(ye)(ye)壓泵(beng)電(dian)(dian)機(ji)控(kong)制(zhi)(zhi)器可以(yi)節約25%的能量，延長蓄電(dian)(dian)池組(zu)單班使用(yong)時間，降(jiang)低(di)液(ye)(ye)壓系統的發熱量。

門架下降采用負載勢能回收技術。金昌叉車門架(jia)下降(jiang)(jiang)(jiang)采用負載(zai)勢能回(hui)收技術可(ke)實現門架(jia)下降(jiang)(jiang)(jiang)的(de)(de)(de)無級調速，還可(ke)節約(yue)5%的(de)(de)(de)能量。負載(zai)勢能回(hui)收的(de)(de)(de)原理是(shi)：門架(jia)下降(jiang)(jiang)(jiang)時，液(ye)壓泵變(bian)成(cheng)液(ye)壓馬達(da)，電(dian)動機變(bian)為發電(dian)機，將負載(zai)的(de)(de)(de)勢能轉化為電(dian)能對蓄電(dian)池進行充電(dian)，以(yi)達(da)到(dao)節約(yue)能量的(de)(de)(de)目的(de)(de)(de)。
