變頻器發熱原因

變頻器和電機本身問(wen)題

電(dian)(dian)機(ji)用久了，不排除絕(jue)緣(yuan)性能(neng)不好，或者軸承(cheng)卡(ka)滯，本身可能(neng)會(hui)出現大(da)電(dian)(dian)流(liu)而發熱(re)。電(dian)(dian)機(ji)和(he)負載之間(jian)的(de)連(lian)軸，也可能(neng)有(you)磨(mo)損，或者電(dian)(dian)機(ji)三相不平衡(heng)，電(dian)(dian)機(ji)的(de)固(gu)定(ding)裝置松動等(deng)等(deng)，連(lian)云港(gang)西(xi)門子V120變頻器，會(hui)引(yin)起異常(chang)聲響和(he)發熱(re)。

變(bian)(bian)頻(pin)器(qi)某些元件(jian)老化，或者矢量參數(shu)和電機匹配上(shang)有(you)偏離，或者轉(zhuan)矩提升等參數(shu)設(she)置過(guo)大，或者加(jia)減速時間過(guo)短，變(bian)(bian)頻(pin)器(qi)載波頻(pin)率太小，都可能引(yin)起電機和變(bian)(bian)頻(pin)器(qi)一起發熱(re)。

電機和變頻器(qi)之間的連(lian)接線，一般不(bu)宜太長了，不(bu)然會(hui)產(chan)生衰減和波形畸(ji)變，如果要使(shi)用，也應該(gai)使(shi)用變頻器(qi)，外(wai)加電抗器(qi)來處理。

有些需(xu)要(yao)快速剎車(che)的(de)場合(he)，需(xu)要(yao)根據制(zhi)(zhi)動(dong)功(gong)率(lv)選購合(he)適的(de)制(zhi)(zhi)動(dong)電阻和制(zhi)(zhi)動(dong)單元(yuan)等配件。
