由變頻器驅(qū)動的電動機節(jié)能

摘要：目前，熱衷于將感應(yīng)電動機或永磁電動機與變頻器組合成可變速控制系統(tǒng)，主要用于風(fēng)機、水泵類負(fù)荷，以實現(xiàn)高效率化和節(jié)能。本文對有關(guān)變頻驅(qū)動電動機節(jié)能的動向、節(jié)能的實例以及對已安裝好電動機改用變頻器驅(qū)動時的注意點予以介紹 敘詞：變頻器 電動機 變頻器驅(qū)動控制 效率 節(jié)能 Abstract：At present, it is common to combine induction motor or permanent magnet motor with transducer to form speed-changeable control system under application of wind turbine loading or water pump loading to realize high efficiency and energy saving. The paper introduces the energy-saving tendency of electromotor driven by transducers and energy-saving cases, and also provides suggestions for modifying electromotor to be driven by transducers.
