:婁底2098-DSD-HV050X羅克韋爾伺服驅(qū)動器怎么樣下表表示恒壓驅(qū)動電路在低速時(shí),對單極與雙極驅(qū)動工作效率的比較。電流與線圈匝數(shù)之積稱為安匝,與轉(zhuǎn)矩成正比,兩者如轉(zhuǎn)速相同,輸出功率也與其有比例關(guān)系。由于低速時(shí),電抗小,電抗如果忽略不計(jì),V/R即為電流,與N之積VN/R變成安匝數(shù)。同樣,雙極電流為V/2R,匝數(shù)也為2N,此積與單極情形相同為VN/R。輸入恒壓驅(qū)動的情形,雙極與單極比較,如下表所示,電流只有單極的1/2,低速時(shí)的效率為單極的2倍。小型化或低速時(shí),要產(chǎn)生大轉(zhuǎn)矩的情況,應(yīng)使用雙極式驅(qū)動,但驅(qū)動電路復(fù)雜。
