描述

1326AB-B740E-21

變頻器作業(yè)時,輸出波形中的高次諧波致使的磁場對許多機(jī)械部件發(fā)作電磁策動力,策動力的頻率總能與某些機(jī)械部件的固有頻率附近或重合,致使共振。

對振動影響大的高次諧波主要是較低次的諧波分量,在PAM(PulseAmplitudeModulation,脈沖幅度調(diào)制)方法和方波PWM方法時有較大的影響。但選用正弦波PWM方法時,低次的諧波分量小,影響變小。用變頻器傳動電動機(jī)時,由于輸出電壓電流中含有高次諧波分量,氣隙的高次諧波磁通增加,故噪聲增大。電磁噪聲有以下特征:由于變頻器輸出中的低次諧波分量與轉(zhuǎn)子固有機(jī)械頻率諧振,則轉(zhuǎn)子固有頻率附近的噪聲增大。變頻器輸出中的高次諧波分量與鐵心機(jī)殼軸承架等諧振,在這些部件的各自固有頻率附近處的噪聲增大。變頻器傳動電動機(jī)發(fā)作的噪聲格外是尖利的噪聲與PWM控制的開關(guān)頻率有關(guān),尤其在低頻區(qū)更為顯著。選用變頻器調(diào)速,將發(fā)作噪聲和振動,這是變頻器輸出波形中含有高次諧波分量所發(fā)作的影響。跟著作業(yè)頻率的改動,基波分量、高次諧波分量都在大范圍內(nèi)改動,很可能致使與電動機(jī)的各個有些發(fā)作諧振等。
振動與噪聲的處置方法削弱或消除振動的方法,可以在變頻器輸出側(cè)接入交流電抗器以吸收變頻器輸出電流中的高次諧波電流成分。
運(yùn)用PAM方法或方波PWM方法變頻器時,可改用正弦波PWM方法變頻器,以減小脈動轉(zhuǎn)矩。為防止電動機(jī)與負(fù)載相連而成的機(jī)械系統(tǒng)振動,有必要使整個系統(tǒng)不與電動機(jī)發(fā)作的電磁力諧振。一般選用以下方法克制和減小噪聲:在變頻器輸出側(cè)聯(lián)接交流電抗器。如果電磁轉(zhuǎn)矩有余量,可將U/f定小些。選用格外電動機(jī)如在較低頻的噪聲音量較嚴(yán)肅時,則要檢查與軸系統(tǒng)(含負(fù)載)固有頻率的諧振。

選擇深圳長欣,選擇放心,售后無憂大量現(xiàn)貨,當(dāng)天順豐發(fā)貨!
主營:本特利,英維思,伍德沃德,??怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂,ACSO,力士樂等各大品牌的DCS系統(tǒng)配件,機(jī)器人系統(tǒng)配件,大型伺服系統(tǒng)備件。

先介紹幾點(diǎn)經(jīng)驗。
1、先通讀一遍“系統(tǒng)手冊”(不管能不能看懂,先了解個大概,以便學(xué)習(xí)編程時查找);
2、由位控邏輯入手,逐漸增加定時、計數(shù)等條件,把或、與、非關(guān)系理順;
3、進(jìn)而練習(xí)整數(shù)運(yùn)算、實數(shù)運(yùn)算、類型轉(zhuǎn)換;
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解(最好是有個物理回路驗證,比如變頻器+電機(jī)+測速傳感器);
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制(盡量避免跳轉(zhuǎn),非跳不可時也是跳的越近越好);
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機(jī)器人配件DSQC系列和Motorola MVME系列,GE 卡件 模塊 驅(qū)動器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌,由于PLC的基本框架大同小異,學(xué)會一種至于其它的學(xué)習(xí)起來也就簡單了。
