松(song)下伺服驅動器是(shi)很(hen)多人喜歡使(shi)用的一種(zhong)設(she)備品牌，但是(shi)它也(ye)并不是(shi)完全沒有毛(mao)病(bing)，比如(ru)有些買家使(shi)用時會(hui)產生漏電的問(wen)題，一般這個電流有多大？下面(mian)康瑞數控來詳細為大家解答(da)。

松下伺服(fu)(fu)(fu)驅動(dong)(dong)器(qi)(qi)漏電(dian)(dian)(dian)(dian)(dian)(dian)是由于軟(ruan)啟(qi)動(dong)(dong)器(qi)(qi)的(de)(de)輸出波型帶(dai)有高次諧波，而電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機及軟(ruan)啟(qi)動(dong)(dong)器(qi)(qi)與(yu)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機間的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)線(xian)會(hui)造(zao)成(cheng)泄漏電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，該泄漏電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)比直流(liu)(liu)驅動(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)機時(shi)變大很(hen)多，因此 造(zao)成(cheng)該狀況(kuang)。伺服(fu)(fu)(fu)控制(zhi)(zhi)板輸出側為PWM波，電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)線(xian)與(yu)地面中(zhong)間有長電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)線(xian)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)效用(yong)，應用(yong)帶(dai)屏蔽(bi)掉層的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)線(xian)時(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)效用(yong)更為顯著。在(zai)(zai)伺服(fu)(fu)(fu)控制(zhi)(zhi)板工作(zuo)中(zhong)時(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)在(zai)(zai)蓄電(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)，有電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)量根據電(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)注入地面，并從三(san)相五線(xian)側的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)接頭(tou)再流(liu)(liu)到(dao)伺服(fu)(fu)(fu)控制(zhi)(zhi)板，產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)量控制(zhi)(zhi)回路。假如在(zai)(zai)三(san)相五線(xian)側應用(yong)了漏電(dian)(dian)(dian)(dian)(dian)(dian)保護(hu)裝置，那麼它會(hui)姿(zi)勢，斷開系(xi)統軟(ruan)件運作(zuo)。

機(ji)(ji)的三相電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)定子繞阻穿(chuan)過電(dian)(dian)(dian)(dian)(dian)流量而造成電(dian)(dian)(dian)(dian)(dian)磁振蕩，依據磁電(dian)(dian)(dian)(dian)(dian)磁感應(ying)(ying)線(xian)圈的基(ji)本(ben)原理(li)，電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)的機(ji)(ji)殼便會造成感應(ying)(ying)電(dian)(dian)(dian)(dian)(dian)流，而感應(ying)(ying)電(dian)(dian)(dian)(dian)(dian)動(dong)勢(shi)的尺寸就(jiu)在于軟啟動(dong)器IGBT的電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)開關(guan)(guan)頻(pin)率的尺寸。因為(wei)性能卓越(yue)的操縱規定高的電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)開關(guan)(guan)頻(pin)率，其電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)開關(guan)(guan)速率迅(xun)速，換句(ju)話說(shuo)，DV/DT偏大(da)，感應(ying)(ying)電(dian)(dian)(dian)(dian)(dian)流就(jiu)稍大(da)，人到觸(chu)碰上便會有(you)觸(chu)電(dian)(dian)(dian)(dian)(dian)的感覺。理(li)論上IGBT的電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)開關(guan)(guan)速率越(yue)快，電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)風罩(zhao)上的感應(ying)(ying)電(dian)(dian)(dian)(dian)(dian)流就(jiu)越(yue)高，而伺服驅動(dong)器對電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)的線(xian)性度和回(hui)應(ying)(ying)就(jiu)越(yue)高，人觸(chu)碰以(yi)后(hou)被電(dian)(dian)(dian)(dian)(dian)的覺得也越(yue)高，相反，IGBT的電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)開關(guan)(guan)頻(pin)率慢(man)，感應(ying)(ying)電(dian)(dian)(dian)(dian)(dian)流就(jiu)小，人觸(chu)碰的覺得就(jiu)小。

松下(xia)伺(si)(si)服(fu)(fu)(fu)驅(qu)動器一(yi)種是電(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)磁效應(ying)造(zao)成(cheng)的(de)(de)(de)(de)漏(lou)(lou)電(dian)(dian)(dian)(dian)，這類狀況便(bian)是在檢(jian)測LUSTservoc配(pei)用的(de)(de)(de)(de)伺(si)(si)服(fu)(fu)(fu)電(dian)(dian)(dian)(dian)動機(ji)(ji)的(de)(de)(de)(de)情況下(xia)，伺(si)(si)服(fu)(fu)(fu)電(dian)(dian)(dian)(dian)動機(ji)(ji)的(de)(de)(de)(de)三根火線(xian)(xian)零(ling)線(xian)(xian)都聯接(jie)到(dao)驅(qu)動器到(dao)了，可是伺(si)(si)服(fu)(fu)(fu)電(dian)(dian)(dian)(dian)動機(ji)(ji)的(de)(de)(de)(de)接(jie)地(di)線(xian)(xian)沒有聯接(jie)到(dao)伺(si)(si)服(fu)(fu)(fu)驅(qu)動器上，運行伺(si)(si)服(fu)(fu)(fu)電(dian)(dian)(dian)(dian)動機(ji)(ji)的(de)(de)(de)(de)情況下(xia)，觸碰伺(si)(si)服(fu)(fu)(fu)電(dian)(dian)(dian)(dian)動機(ji)(ji)造(zao)成(cheng) 觸電(dian)(dian)(dian)(dian)事故。也有一(yi)種漏(lou)(lou)電(dian)(dian)(dian)(dian)便(bian)是火線(xian)(xian)零(ling)線(xian)(xian)的(de)(de)(de)(de)絕緣(yuan)層(ceng)毀損，造(zao)成(cheng) 漏(lou)(lou)電(dian)(dian)(dian)(dian)。

因(yin)為三(san)相異步電(dian)機(ji)運(yun)行，電(dian)機(ji)風罩(zhao)都(dou)是會有感應電(dian)壓，即說白了的(de)漏電(dian)，因(yin)此(ci)(ci) ，電(dian)動(dong)(dong)機(ji)生產廠才會在(zai)電(dian)動(dong)(dong)機(ji)原廠的(de)情況下，在(zai)其(qi)接線端子里邊裝(zhuang)上接線端子排，以(yi)處理身體(ti)觸碰(peng)電(dian)動(dong)(dong)機(ji)時(shi)(shi)被觸的(de)覺得。而(er)伺服驅動(dong)(dong)器(qi)操(cao)(cao)縱時(shi)(shi)，因(yin)為其(qi)電(dian)源開(kai)關(guan)頻(pin)率(lv)都(dou)比直流頻(pin)率(lv)高(gao)得多，因(yin)此(ci)(ci) 伺服驅動(dong)(dong)器(qi)在(zai)操(cao)(cao)縱電(dian)動(dong)(dong)機(ji)旋轉時(shi)(shi)，電(dian)機(ji)風罩(zhao)便會有漏電(dian)的(de)覺得。

以上(shang)就是(shi)康瑞數控為大家分(fen)享的(de)“松下伺服驅(qu)動器漏電大小(xiao)”，希望能(neng)對您有(you)所(suo)幫(bang)助。一般來說(shuo)只要運(yun)轉(zhuan)的(de)速度不是(shi)太(tai)快，電流也不會太(tai)大，如果(guo)太(tai)快也會導致增大。
