騰升科技青島磁滯制動(dòng)器廠家質(zhì)優(yōu)價(jià)廉,

磁滯制動(dòng)器是一種優(yōu)越的扭矩、張力控制部件.它利用磁滯原理,通過控制輸入的勵(lì)磁電流,產(chǎn)生一定的扭矩.控制電流和輸出扭矩有較好的線性關(guān)系.它能提供光滑,、無級(jí)可調(diào),、與轉(zhuǎn)速無關(guān)的轉(zhuǎn)矩控制.除了軸承以外,系統(tǒng)內(nèi)無其它摩擦,具有穩(wěn)定可靠、使用轉(zhuǎn)速高噪音小、使用壽命長(zhǎng),維護(hù)成本低等優(yōu)點(diǎn).

結(jié)構(gòu)特征 

磁滯制動(dòng)器由轉(zhuǎn)子和定子磁極兩大部分組成.轉(zhuǎn)子由特殊的磁滯材料制成,定子磁極中有一定的間隙,轉(zhuǎn)子在間隙中轉(zhuǎn)動(dòng).當(dāng)線圈通電時(shí),間隙中產(chǎn)生磁場(chǎng),使轉(zhuǎn)子產(chǎn)生磁滯效應(yīng).當(dāng)磁滯轉(zhuǎn)子在外力作用下克服磁滯力轉(zhuǎn)動(dòng)時(shí),產(chǎn)生額定的扭矩.扭矩僅與激磁電流大小有關(guān),與轉(zhuǎn)速無關(guān),實(shí)現(xiàn)非接觸的扭矩傳輸.
