電(dian)機(ji)是全自(zi)動(dong)鋸邊(bian)機(ji)的(de)核心(xin)部件，是全自(zi)動(dong)鋸邊(bian)機(ji)的(de)動(dong)力來源(yuan)，如果出現電(dian)機(ji)過(guo)熱(re)的(de)現象，就一定要重視(shi)起來。
電(dian)(dian)(dian)(dian)(dian)機(ji)通(tong)(tong)電(dian)(dian)(dian)(dian)(dian)工作的時候(hou)(hou)，如果電(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)壓過高(gao)，電(dian)(dian)(dian)(dian)(dian)機(ji)的反電(dian)(dian)(dian)(dian)(dian)勢能、磁(ci)通(tong)(tong)以(yi)及(ji)磁(ci)通(tong)(tong)密(mi)度(du)全(quan)部都會(hui)變(bian)大。因為鐵(tie)(tie)耗損(sun)的高(gao)低與(yu)磁(ci)通(tong)(tong)密(mi)度(du)平方成正比，則鐵(tie)(tie)耗損(sun)提升，導致(zhi)鐵(tie)(tie)心溫度(du)過高(gao)。如果電(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)壓過低的時候(hou)(hou)，咱(zan)們假設電(dian)(dian)(dian)(dian)(dian)機(ji)的電(dian)(dian)(dian)(dian)(dian)磁(ci)轉(zhuan)(zhuan)距保持(chi)不變(bian)，磁(ci)通(tong)(tong)將下降，轉(zhuan)(zhuan)子(zi)電(dian)(dian)(dian)(dian)(dian)流(liu)相對應變(bian)大，定(ding)子(zi)電(dian)(dian)(dian)(dian)(dian)流(liu)中負載電(dian)(dian)(dian)(dian)(dian)源分(fen)量隨(sui)著提升，導致(zhi)繞線(xian)的銅耗損(sun)變(bian)大。
而當三相電(dian)源不(bu)穩定平(ping)衡時，會(hui)(hui)使(shi)電(dian)機的三相電(dian)流不(bu)平(ping)衡，也會(hui)(hui)造(zao)成(cheng)繞阻(zu)溫度過高。
