近年(nian)來，節能(neng)機電(dian)設備一直處(chu)于(yu)不冷(leng)不熱狀態，然而(er)，隨著我(wo)國乃至世界范圍內(nei)，倡導低(di)碳(tan)、節能(neng)減排政策的推動下，節能(neng)機電(dian)設備推廣應用(yong)必將出(chu)現實質性的進(jin)展。

機械行業(ye)分(fen)析師認(ren)為，目前(qian)，我國電(dian)(dian)機產(chan)(chan)品種類繁多，但效率不(bu)高。電(dian)(dian)機系統(tong)效率低(di)下，長期低(di)效運行。一些生產(chan)(chan)電(dian)(dian)機系統(tong)的(de)用戶對電(dian)(dian)機系統(tong)所(suo)帶(dai)來(lai)的(de)經濟效益(yi)缺乏認(ren)知(zhi)，或對進行電(dian)(dian)機系統(tong)節能(neng)(neng)改造的(de)技術(shu)題目存在(zai)障礙，機電(dian)(dian)業(ye)必須加強節能(neng)(neng)技術(shu)的(de)研發(fa)(fa)和創(chuang)新，使(shi)其真(zhen)正發(fa)(fa)揮其基礎(chu)性產(chan)(chan)業(ye)的(de)作(zuo)用，帶(dai)動(dong)國民經濟持續(xu)健(jian)康發(fa)(fa)展。

預計，未來幾年，節能電(dian)機設備占國內新增中(zhong)小型機電(dian)設備的比(bi)例將達到60%以上，節能機電(dian)設備市場(chang)規模將達到五百億左右。

據(ju)《2011年中(zhong)國發電(dian)(dian)機(ji)行業(ye)市場前景與投資(zi)價值分析報告》顯(xian)示，2011年電(dian)(dian)機(ji)的(de)推廣任務是3177千(qian)瓦(wa)，約占全年國內(nei)電(dian)(dian)機(ji)銷(xiao)售量比重(zhong)的(de)30%，其中(zhong)低壓電(dian)(dian)機(ji)2000萬(wan)千(qian)瓦(wa)、高壓電(dian)(dian)機(ji)1000萬(wan)千(qian)瓦(wa)，稀(xi)土(tu)永磁電(dian)(dian)機(ji)177萬(wan)千(qian)瓦(wa)。隨著(zhu)國家(jia)節(jie)能(neng)減排的(de)積極推行及節(jie)能(neng)電(dian)(dian)機(ji)補(bu)貼政策的(de)逐步落(luo)實，節(jie)能(neng)電(dian)(dian)機(ji)業(ye)將(jiang)迎來爆發式(shi)的(de)增長。

步進(jin)電(dian)(dian)(dian)機是一(yi)種(zhong)特殊的(de)無刷直流電(dian)(dian)(dian)機，電(dian)(dian)(dian)磁線圈(quan)布置在電(dian)(dian)(dian)機的(de)外部(bu)，電(dian)(dian)(dian)機的(de)中心有一(yi)個鐵或(huo)磁芯附(fu)在軸上。通過對線圈(quan)電(dian)(dian)(dian)壓進(jin)行排序(xu)，可以(yi)以(yi)相對較低的(de)成本(ben)實現(xian)的(de)旋轉控制。控制通常是開環的(de)，所以(yi)系統不知道電(dian)(dian)(dian)機是否失速或(huo)與控制器失去同步。

1.穩定(ding)，可以驅動(dong)廣泛的摩擦和(he)慣性負載(zai)。

2.不需要反饋，電機就是位(wei)置傳(chuan)感器。

3.與其他(ta)運(yun)動控制系統(tong)相比價格便宜。

4.標準(zhun)化的框架尺寸和(he)性能。

5.即插即用(yong)，易于設置和使(shi)用(yong)。

6.安全，系統(tong)有什么零件損壞，馬達就停了。

7.壽(shou)命長，軸承是磨(mo)損機制(zhi)。

8.出色的低(di)速扭矩，可以(yi)在不帶齒輪(lun)的情況下驅動許多(duo)負載。

9.的重復性(xing)，準確(que)返(fan)回同(tong)一位置。

10.超載安(an)全，電機(ji)(ji)不能(neng)因機(ji)(ji)械過(guo)載而損壞(huai)。
