:中山AB羅克韋爾伺服驅(qū)動(dòng)器2098-DSD-010X圖片還有一種特殊情況,若電動(dòng)機(jī)的負(fù)載較輕(小于額定負(fù)載的40%),則不需較大的負(fù)載電流來產(chǎn)生電磁轉(zhuǎn)矩去克服阻力矩,此時(shí)定子繞組由三角形接法改為星形接法,由于繞組相電壓大大降低,勵(lì)磁電流明顯減少,所以總的定子電流也減小,而電機(jī)的功率因數(shù)和效率則相應(yīng)提高。當(dāng)大拉小車時(shí),即電機(jī)的負(fù)載小于額定負(fù)載的40%時(shí)人為將電機(jī)由三角形改為星形,達(dá)到節(jié)能降耗的目的。以上就是本人的一點(diǎn)經(jīng)驗(yàn)總結(jié),尤其希望對(duì)電工新人有所幫助,共同學(xué)習(xí)進(jìn)步。
