智能軸承加熱器是內(nei)(nei)(nei)、外圈(quan)(quan)(quan)(quan)(quan)同(tong)(tong)時加(jia)熱(re)，因(yin)為內(nei)(nei)(nei)圈(quan)(quan)(quan)(quan)(quan)磁通量(liang)較外圈(quan)(quan)(quan)(quan)(quan)大，所以(yi)內(nei)(nei)(nei)圈(quan)(quan)(quan)(quan)(quan)與(yu)外圈(quan)(quan)(quan)(quan)(quan)存在(zai)溫(wen)度(du)上的差別。軸(zhou)承(cheng)(cheng)與(yu)軸(zhou)的配合表(biao)面是內(nei)(nei)(nei)圈(quan)(quan)(quan)(quan)(quan)的內(nei)(nei)(nei)徑表(biao)面，因(yin)此以(yi)內(nei)(nei)(nei)圈(quan)(quan)(quan)(quan)(quan)的溫(wen)度(du)為準，這也是為什么加(jia)熱(re)時需把溫(wen)度(du)傳感器吸(xi)附在(zai)軸(zhou)承(cheng)(cheng)內(nei)(nei)(nei)圈(quan)(quan)(quan)(quan)(quan)上。由(you)于軛鐵(tie)中心(xin)與(yu)軸(zhou)承(cheng)(cheng)軸(zhou)心(xin)不(bu)可能完全重疊，所以(yi)軸(zhou)承(cheng)(cheng)內(nei)(nei)(nei)圈(quan)(quan)(quan)(quan)(quan)各(ge)點的磁通量(liang)有差異(yi)，同(tong)(tong)一內(nei)(nei)(nei)圈(quan)(quan)(quan)(quan)(quan)各(ge)點存在(zai)一定誤差屬于正常現象(xiang)，溫(wen)度(du)大約在(zai)3℃左右。

電(dian)(dian)磁(ci)感(gan)應軸(zhou)承加熱(re)(re)技(ji)術是(shi)一種(zhong)先(xian)進(jin)的電(dian)(dian)加熱(re)(re)技(ji)術，它是(shi)通過電(dian)(dian)磁(ci)場傳輸能量，使(shi)金屬被加熱(re)(re)體(ti)自身(shen)發熱(re)(re)從而(er)達到加熱(re)(re)的目的。電(dian)(dian)磁(ci)加熱(re)(re)系統(tong)一般包(bao)含電(dian)(dian)磁(ci)加熱(re)(re)控制(zhi)板(ban)和加熱(re)(re)線圈兩(liang)部分。電(dian)(dian)磁(ci)感(gan)應加熱(re)(re)控制(zhi)板(ban)通過將電(dian)(dian)源的輸入工頻交(jiao)(jiao)流電(dian)(dian)進(jin)行(xing)整流、濾(lv)波成之流，再逆(ni)變成16~30kHz的高頻交(jiao)(jiao)流電(dian)(dian)，并輸送到電(dian)(dian)磁(ci)加熱(re)(re)圈上，被加熱(re)(re)體(ti)通過接收電(dian)(dian)磁(ci)加熱(re)(re)線圈上的高頻交(jiao)(jiao)變電(dian)(dian)磁(ci)場，形成感(gan)應電(dian)(dian)流而(er)發熱(re)(re)。

可以通過在被加熱體上安裝溫度控制器來控制電磁加熱控制板，從而對被加熱體的溫度進行控制。由于使用電磁加熱技術時，可以在加熱體增加隔熱保溫材料，這樣就可以大大減少被加熱體與周圍環境的熱交換，減少熱量損失，從而提高設備的電能利用效率，節約電能。采用電磁感應軸承加熱器，一般可以節約30%~80%的電能，節能效果非常明顯。
