騰升科技長春磁滯制動器廠家質(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?？刂齐娏骱洼敵雠ぞ赜休^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。
