高壓變(bian)頻器(qi)(qi)有(you)幾部(bu)分組成　　主回(hui)路(lu)主要由三相或單(dan)相整流橋、平滑電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)、濾波(bo)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)、IPM逆(ni)變(bian)橋、限(xian)流電(dian)(dian)(dian)(dian)(dian)阻、接觸器(qi)(qi)等元件組成。其中許多常見故障是由電(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)引起(qi)。電(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)的(de)壽(shou)命主要由加在其兩端的(de)直流電(dian)(dian)(dian)(dian)(dian)壓和內部(bu)溫(wen)度所決定(ding)(ding)，在回(hui)路(lu)設(she)計時已經選定(ding)(ding)了電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)的(de)型號，所以內部(bu)的(de)溫(wen)度對(dui)電(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)的(de)壽(shou)命起(qi)決定(ding)(ding)作用(yong)。電(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)會直接影響到變(bian)頻器(qi)(qi)的(de)使用(yong)壽(shou)命，一(yi)般溫(wen)度每上升10℃，壽(shou)命減(jian)半。因此(ci)一(yi)方(fang)面(mian)在安裝時要考慮適當的(de)環境溫(wen)度，另一(yi)方(fang)面(mian)可以采(cai)取措施減(jian)少(shao)脈動電(dian)(dian)(dian)(dian)(dian)流。采(cai)用(yong)改*功(gong)率因數(shu)的(de)交流或直流電(dian)(dian)(dian)(dian)(dian)抗器(qi)(qi)可以減(jian)少(shao)脈動電(dian)(dian)(dian)(dian)(dian)流，從(cong)而延

松下(xia)伺服(fu)電(dian)機(ji)(ji)與步(bu)進電(dian)機(ji)(ji)的區(qu)別：　       松下(xia)伺服(fu)電(dian)機(ji)(ji)： 　　一、高速(su)(su)，高響應，大扭矩(ju)(ju)，轉(zhuan)(zhuan)矩(ju)(ju)大，過載能(neng)力強，高精度定位，恒(heng)力矩(ju)(ju)輸出     1，高速(su)(su)度，松下(xia)伺服(fu)電(dian)機(ji)(ji)最高轉(zhuan)(zhuan)速(su)(su)可(ke)以達(da)(da)6500轉(zhuan)(zhuan)；     2，高響應，響應頻率3.2KHz達(da)(da)到更高速(su)(su)動作，提高生產性；
