在(zai)使(shi)用(yong)新的或大(da)修(xiu)過的懸臂電(dian)(dian)機之前，除了一般的外觀檢查(cha)和(he)轉子(zi)的靈活(huo)性外，還需要用(yong)手表(biao)檢查(cha).定(ding)子(zi)絕緣(yuan)電(dian)(dian)阻(zu)應大(da)于2 mΩ;轉子(zi)絕緣(yuan)電(dian)(dian)阻(zu)在(zai)0.8米Ω，否則必(bi)須干(gan)燥.干(gan)燥方(fang)法是將(jiang)整(zheng)個電(dian)(dian)機裝(zhuang)入干(gan)燥箱或低壓(ya)短(duan)路(lu)電(dian)(dian)流(liu).后者(zhe)是將(jiang)每相繞組的末(mo)端(duan)和(he)首(shou)端(duan)連(lian)接到(dao)額(e)定(ding)電(dian)(dian)壓(ya)20%.

對于多電(dian)(dian)(dian)機(ji)驅動機(ji)構(gou)，如單獨的(de)驅動機(ji)構(gou)，每(mei)臺防(fang)爆(bao)環鏈電(dian)(dian)(dian)動葫蘆(lu)必須具有(you)與每(mei)臺防(fang)爆(bao)環鏈電(dian)(dian)(dian)動葫蘆(lu)相同(tong)的(de)機(ji)械性(xing)能(neng).另外，由于懸臂起重機(ji)電(dian)(dian)(dian)機(ji)和電(dian)(dian)(dian)阻器存在著制造公(gong)差(cha)，以及電(dian)(dian)(dian)機(ji)連接線(xian)長度的(de)使用不同(tong)等因(yin)素，會導(dao)致電(dian)(dian)(dian)機(ji)的(de)機(ji)械性(xing)能(neng).為了保證每(mei)個(ge)電(dian)(dian)(dian)機(ji)具有(you)相同(tong)的(de)機(ji)械性(xing)能(neng)，可以采(cai)用長轉(zhuan)子電(dian)(dian)(dian)阻的(de)方法.

檢查懸(xuan)臂電機的力(li)學性能是否(fou)一(yi)致(zhi)(zhi)，可以用來測量該負載中兩(liang)個(ge)主動輪(lun)速度的一(yi)致(zhi)(zhi)性.

防爆(bao)環鏈(lian)電(dian)動葫蘆(lu)在空載狀態(tai)下的電(dian)流大小是電(dian)機質量(liang)好壞的一(yi)個解釋.電(dian)機空載電(dian)流約為額定值的0.6~0.75倍.如果超過這一(yi)點，懸(xuan)臂馬達會導(dao)致(zhi)操作中的高溫上升.電(dian)機容量(liang)越(yue)大，其值越(yue)小;反之，其值越(yue)大
