騰升科技青島磁滯制動器廠家質(zhì)優(yōu)價廉,

磁滯制動器是一種優(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,維護(hù)成本低等優(yōu)點.

結(jié)構(gòu)特征 

磁滯制動器由轉(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.當(dāng)線圈通電時,間隙中產(chǎn)生磁場,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)動時,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),實現(xiàn)非接觸的扭矩傳輸.
