ZF20000磁粉測功機特點：

1. 轉(zhuan)子(zi)為空心(xin)(xin)鼓形轉(zhuan)子(zi)，慣(guan)性小，承受離心(xin)(xin)力大。
2. 測功(gong)機(ji)的力(li)矩產生(sheng)是(shi)由磁粉(fen)鏈的拉(la)力(li)形成，力(li)矩變化具(ju)有(you)緩沖性。
3. 靜態(tai)轉(zhuan)矩(ju)力矩(ju)平滑，沒有齒(chi)槽波動轉(zhuan)矩(ju)，無剩磁轉(zhuan)矩(ju)。
4. 無摩(mo)擦結構，使用壽命長(chang)。
5. 操作方便(bian),只需調節激(ji)磁電流即可改變(bian)測功機的(de)力矩大小。

ZF20000磁粉測功機基(ji)本特性：

（1）勵磁(ci)電流(liu)——力矩特性(xing)勵磁(ci)電流(liu)與轉(zhuan)矩基本成線(xian)性(xing)關(guan)系(xi)，通(tong)過調節(jie)勵磁(ci)電流(liu)可以控制力矩的大小。

1. 轉(zhuan)(zhuan)(zhuan)速——力矩特性力矩與轉(zhuan)(zhuan)(zhuan)速無關(guan)，保持定值。(勵磁電流不(bu)變(bian)時，在允許(xu)的轉(zhuan)(zhuan)(zhuan)速范圍內轉(zhuan)(zhuan)(zhuan)矩不(bu)受轉(zhuan)(zhuan)(zhuan)速高低變(bian)化的影響)靜力矩和動力矩沒有差別。
2. 負(fu)載特性(xing)測功(gong)機(ji)的允許(xu)運行(xing)功(gong)率(lv)(lv),在散熱(re)條件一定時(shi),是(shi)定值。其實(shi)際選(xuan)用選(xuan)型時(shi)，實(shi)用運行(xing)功(gong)率(lv)(lv)需在允允許(xu)功(gong)率(lv)(lv)以(yi)內。使用轉速(su)高(gao)時(shi)，需降低力(li)矩使用。例：ZF100測功(gong)機(ji)：額定力(li)矩：M=100N.m滑差功(gong)率(lv)(lv)：P=8KW則轉速(su)：n=800rpm如(ru)轉速(su)：n=1500rpm時(shi)連(lian)續運行(xing)，則允許(xu)力(li)矩應為M=9550P/n=9550×8/1500=50.9N.m（式中9550為單位(wei)換(huan)算常(chang)數）即如(ru)轉速(su)提(ti)高(gao)為1500rpm時(shi)，力(li)矩只(zhi)能(neng)在50N.m以(yi)下連(lian)續使用。否則溫度連(lian)續升高(gao)。

選(xuan)(xuan)型一般以所(suo)需傳遞的大轉(zhuan)矩(ju)來(lai)選(xuan)(xuan)定(ding)，并注意保證實際使(shi)用的運行(xing)功(gong)(gong)率(lv)(lv)，應(ying)小于(yu)技(ji)術參(can)數的允許運行(xing)功(gong)(gong)率(lv)(lv)，余量大點更能延長使(shi)用壽命。

應用(yong)(yong)場合：用(yong)(yong)于中大力矩(ju)而轉(zhuan)速低的電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)測試，如起動(dong)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)恒力矩(ju)帶載起動(dong)、異步電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)、直流減速電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)、直流電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)、電(dian)(dian)(dian)(dian)動(dong)工具、三(san)相電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)、同步電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)、調速電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)、步進(jin)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)、雨刮器電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)、搖窗電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)、汽車暖風電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)、電(dian)(dian)(dian)(dian)動(dong)車電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)及造(zao)紙、紡(fang)織(zhi)等(deng)行業使用(yong)(yong)的恒張(zhang)力控(kong)制等(deng)。
