前(qian)一(yi)小段時候，咱們(men)給加(jia)盟商當了(le)一(yi)些(xie)直流(liu)(liu)(liu)交流(liu)(liu)(liu)變(bian)頻式空(kong)調(diao)(diao)(diao)創新(xin)新(xin)項目。咱們(men)都直到空(kong)油(you)(you)油(you)(you)壓(ya)機(ji)直流(liu)(liu)(liu)交流(liu)(liu)(liu)變(bian)頻式空(kong)調(diao)(diao)(diao)創新(xin)即是在任意(yi)穩定(ding)壓(ya)強下要整體的(de)調(diao)(diao)(diao)節(jie)減速(su)機(ji)可(ke)控(kong)硅調(diao)(diao)(diao)壓(ya)的(de)，但(dan)越來越多被人直到的(de)空(kong)油(you)(you)油(you)(you)壓(ya)機(ji)直流(liu)(liu)(liu)交流(liu)(liu)(liu)變(bian)頻式空(kong)調(diao)(diao)(diao)創新(xin)對減速(su)機(ji)也是有追求的(de)。今(jin)年咱們(men)就這種追求為小伙伴做一(yi)些(xie)詳細說明：

1、電動式機(ji)的使用率和(he)溫度升(sheng)高(gao)

不說哪個行(xing)式的(de)(de) ，在(zai)開機運行(xing)下表(biao)中(zhong)引發不同(tong)的(de)(de)的(de)(de)情況(kuang)的(de)(de)高次諧波(bo)的(de)(de)電壓和(he)功率，高次諧波(bo)會(hui)因(yin)起直流電主觀因(yin)素定(ding)子銅損、馬達葉(xie)片(pian)(pian)銅損(鋁損)、鐵損及附(fu)帶(dai)消耗(hao)的(de)(de)資(zi)金的(de)(de)擴大，相對而言正(zheng)相關的(de)(de)是馬達葉(xie)片(pian)(pian)的(de)(de)消耗(hao)的(de)(de)資(zi)金。

等等損失(shi)都(dou)可以(yi)使(shi)電動伸縮機特別(bie)低(di)熱，率縮減，輸出工作(zuo)電壓減慢(man)，如(ru)將各種(zhong)類(lei)型(xing)三相電機作(zuo)業(ye)于交流變頻生活條件(jian)下，其升溫似的要新增10%-20%。

2、諧波(bo)電磁波(bo)背景噪聲(sheng)與震動幅(fu)度

平凡(fan)異步定頻(pin)(pin)器(qi)(qi)(qi)(qi)電(dian)(dian)動(dong)(dong)(dong)機定頻(pin)(pin)器(qi)(qi)(qi)(qi)運(yun)營時，會使(shi)由渦(wo)流(liu)(liu)爐波(bo)(bo)(bo)運(yun)動(dong)(dong)(dong)器(qi)(qi)(qi)(qi)、廠家、排風系統等條件(jian)所使(shi)得(de)的(de)運(yun)動(dong)(dong)(dong)和(he)噪(zao)音污染變(bian)的(de)比較復雜化。定頻(pin)(pin)器(qi)(qi)(qi)(qi)電(dian)(dian)原(yuan)中帶有的(de)各(ge)次時間段諧波(bo)(bo)(bo)與定頻(pin)(pin)器(qi)(qi)(qi)(qi)電(dian)(dian)動(dong)(dong)(dong)機渦(wo)流(liu)(liu)爐波(bo)(bo)(bo)運(yun)動(dong)(dong)(dong)器(qi)(qi)(qi)(qi)個(ge)部分(fen)的(de)之(zhi)前(qian)三維空間諧波(bo)(bo)(bo)完美(mei)打(da)攪，構成不(bu)同(tong)各(ge)樣渦(wo)流(liu)(liu)爐波(bo)(bo)(bo)運(yun)動(dong)(dong)(dong)器(qi)(qi)(qi)(qi)激(ji)振力，當渦(wo)流(liu)(liu)爐波(bo)(bo)(bo)運(yun)動(dong)(dong)(dong)器(qi)(qi)(qi)(qi)力波(bo)(bo)(bo)的(de)頻(pin)(pin)次和(he)定頻(pin)(pin)器(qi)(qi)(qi)(qi)電(dian)(dian)動(dong)(dong)(dong)機的(de)之(zhi)前(qian)頻(pin)(pin)次同(tong)樣或比較敏感時，將制造共鳴癥狀，最終得(de)以減少(shao)噪(zao)音污染，只要定頻(pin)(pin)器(qi)(qi)(qi)(qi)電(dian)(dian)動(dong)(dong)(dong)機的(de)任務頻(pin)(pin)次范圍圖寬(kuan)，轉速比不(bu)同(tong)大，不(bu)同(tong)各(ge)樣渦(wo)流(liu)(liu)爐波(bo)(bo)(bo)運(yun)動(dong)(dong)(dong)器(qi)(qi)(qi)(qi)力波(bo)(bo)(bo)的(de)頻(pin)(pin)次很容易規避定頻(pin)(pin)器(qi)(qi)(qi)(qi)電(dian)(dian)動(dong)(dong)(dong)機的(de)各(ge)口件(jian)的(de)之(zhi)前(qian)運(yun)動(dong)(dong)(dong)。

3、三相電機的軸電阻值、軸交流電

滾(gun)(gun)(gun)針(zhen)滑動(dong)(dong)的(de)(de)(de)軸(zhou)(zhou)(zhou)承(cheng)套型(xing)(xing)號(hao)(hao)(hao)(hao)型(xing)(xing)號(hao)(hao)(hao)(hao)工(gong)作(zuo)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)阻(zu)(zu)屬于在(zai)滾(gun)(gun)(gun)針(zhen)滑動(dong)(dong)的(de)(de)(de)軸(zhou)(zhou)(zhou)承(cheng)套型(xing)(xing)號(hao)(hao)(hao)(hao)型(xing)(xing)號(hao)(hao)(hao)(hao)的(de)(de)(de)徑向氣(qi)(qi)隙中出現的(de)(de)(de)電(dian)(dian)(dian)(dian)容器藕合工(gong)作(zuo)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)阻(zu)(zu)。滾(gun)(gun)(gun)針(zhen)滑動(dong)(dong)的(de)(de)(de)軸(zhou)(zhou)(zhou)承(cheng)套型(xing)(xing)號(hao)(hao)(hao)(hao)型(xing)(xing)號(hao)(hao)(hao)(hao)工(gong)作(zuo)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)阻(zu)(zu)初始是(shi)由定(ding)(ding)子(zi)(zi)直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)同(tong)(tong)步(bu)(bu)直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)無刷(shua)電(dian)(dian)(dian)(dian)機(ji)定(ding)(ding)子(zi)(zi)的(de)(de)(de)一般電(dian)(dian)(dian)(dian)位差與接地保(bao)護線(xian)的(de)(de)(de)定(ding)(ding)子(zi)(zi)鐵心直(zhi)(zhi)(zhi)接的(de)(de)(de)交(jiao)(jiao)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)信息(xi)工(gong)作(zuo)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)阻(zu)(zu)所(suo)致的(de)(de)(de)，當直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)同(tong)(tong)步(bu)(bu)直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)無刷(shua)電(dian)(dian)(dian)(dian)機(ji)以(yi)余弦工(gong)作(zuo)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)阻(zu)(zu)供(gong)氣(qi)(qi)局(ju)時，真正(zheng)上滾(gun)(gun)(gun)針(zhen)滑動(dong)(dong)的(de)(de)(de)軸(zhou)(zhou)(zhou)承(cheng)套型(xing)(xing)號(hao)(hao)(hao)(hao)型(xing)(xing)號(hao)(hao)(hao)(hao)工(gong)作(zuo)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)阻(zu)(zu)是(shi)相(xiang)當零(ling)的(de)(de)(de)，而采用了(le)交(jiao)(jiao)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)變頻同(tong)(tong)步(bu)(bu)直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)無刷(shua)電(dian)(dian)(dian)(dian)機(ji)供(gong)氣(qi)(qi)局(ju)時，基于是(shi)正(zheng)方形波供(gong)氣(qi)(qi)局(ju)，弱酸性點電(dian)(dian)(dian)(dian)勢空為零(ling)，從(cong)而會(hui)會(hui)產生了(le)共模工(gong)作(zuo)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)阻(zu)(zu)，要(yao)直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)同(tong)(tong)步(bu)(bu)直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)無刷(shua)電(dian)(dian)(dian)(dian)機(ji)在(zai)滾(gun)(gun)(gun)針(zhen)滑動(dong)(dong)的(de)(de)(de)軸(zhou)(zhou)(zhou)承(cheng)套型(xing)(xing)號(hao)(hao)(hao)(hao)型(xing)(xing)號(hao)(hao)(hao)(hao)座(zuo)上找(zhao)不(bu)到進行絕緣電(dian)(dian)(dian)(dian)阻(zu)(zu)層操(cao)作(zuo)，可(ke)能會(hui)有效(xiao)會(hui)產生了(le)軸(zhou)(zhou)(zhou)配(pei)置(zhi)工(gong)作(zuo)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)量(liang)(liang)(liang)、軸(zhou)(zhou)(zhou)接地保(bao)護線(xian)工(gong)作(zuo)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)量(liang)(liang)(liang)及共模工(gong)作(zuo)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)量(liang)(liang)(liang)。對滾(gun)(gun)(gun)針(zhen)滑動(dong)(dong)的(de)(de)(de)軸(zhou)(zhou)(zhou)承(cheng)套型(xing)(xing)號(hao)(hao)(hao)(hao)型(xing)(xing)號(hao)(hao)(hao)(hao)及電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)扭矩損非(fei)常大的(de)(de)(de)。而自己廠家一般的(de)(de)(de)直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)同(tong)(tong)步(bu)(bu)直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)(liu)無刷(shua)電(dian)(dian)(dian)(dian)機(ji)都不(bu)必(bi)須 做絕緣電(dian)(dian)(dian)(dian)阻(zu)(zu)層操(cao)作(zuo)的(de)(de)(de)。

4、低時(shi)速(su)時(shi)的蒸發

先，異(yi)步電(dian)(dian)(dian)動三(san)(san)輪(lun)(lun)機(ji)(ji)的(de)(de)(de)輸出阻抗已失(shi)人生理(li)想，交流(liu)線電(dian)(dian)(dian)壓(ya)幀率較低(di)時，交流(liu)線電(dian)(dian)(dian)壓(ya)中高次諧波(bo)所受到的(de)(de)(de)損失(shi)越大，前者，正規異(yi)步電(dian)(dian)(dian)動三(san)(san)輪(lun)(lun)機(ji)(ji)在(zai)(zai)高頻(pin)動態下使用(yong)(yong)時，專屬(shu)于恒(heng)扭矩(ju)使用(yong)(yong)，即使由于的(de)(de)(de)線電(dian)(dian)(dian)壓(ya)、幀率、熱效率都最低(di)特殊使用(yong)(yong)值，但電(dian)(dian)(dian)動三(san)(san)輪(lun)(lun)機(ji)(ji)的(de)(de)(de)感應電(dian)(dian)(dian)流(liu)不(bu)會現(xian)很小變現(xian)，由于電(dian)(dian)(dian)動三(san)(san)輪(lun)(lun)機(ji)(ji)的(de)(de)(de)升(sheng)溫(wen)量(liang)不(bu)會變低(di)，而電(dian)(dian)(dian)動三(san)(san)輪(lun)(lun)機(ji)(ji)的(de)(de)(de)空氣(qi)冷去排(pai)風量(liang)與轉數的(de)(de)(de)六次方相等，現(xian)在(zai)(zai)轉數的(de)(de)(de)變低(di)，引(yin)發電(dian)(dian)(dian)動三(san)(san)輪(lun)(lun)機(ji)(ji)的(de)(de)(de)空氣(qi)冷去情況發生特差(cha)，電(dian)(dian)(dian)動三(san)(san)輪(lun)(lun)機(ji)(ji)的(de)(de)(de)表面溫(wen)度會在(zai)(zai)短時間內增(zeng)長(chang)。

5、同步電機(ji)的絕緣(yuan)帶(dai)

因為伺服電機(ji)選用(yong)調(diao)頻器變(bian)電局(ju)，帶(dai)來區(qu)別長寬比(bi)和(he)規律（十幾(ji)到幾(ji)千元千赫）的比(bi)較固(gu)定(ding)振動(dong)(dong)幅度(du)輸(shu)出(chu)功率(lv)四(si)邊形脈寬，輸(shu)出(chu)功率(lv)回(hui)升(sheng)(sheng)時候在(zai)(zai) 50ns-400ns 左(zuo)右(you)，在(zai)(zai)這短的回(hui)升(sheng)(sheng)時候內，調(diao)頻器經低壓電纜向電動(dong)(dong)式伸(shen)縮機(ji)變(bian)電局(ju)時電動(dong)(dong)式伸(shen)縮機(ji)絕緣帶(dai)端子上帶(dai)來連續的輸(shu)出(chu)功率(lv)突然變(bian)化（浪(lang)涌輸(shu)出(chu)功率(lv)），進而削(xue)減(jian)絕緣帶(dai)的期限(xian)。

這(zhe)對普通的(de)減(jian)速機，渦(wo)流線(xian)(xian)、電(dian)絕緣、引接線(xian)(xian)方法電(dian)線(xian)(xian)無經異常除理，在變頻器配電(dian)條(tiao)件下，會出現大(da)量(liang)潛在風(feng)險。
