:柳州2098-DSD-HV050X羅克韋爾伺服驅(qū)動(dòng)器圖片)機(jī)械原因引起的振動(dòng)表現(xiàn)為:電動(dòng)機(jī)軸上有外伸重量,軸系統(tǒng)的固有頻率降低時(shí),如果電動(dòng)機(jī)高速運(yùn)轉(zhuǎn),全旋轉(zhuǎn)頻率與軸系統(tǒng)固有頻率接近,則振動(dòng)加劇。轉(zhuǎn)子殘余不平衡引起離心力與轉(zhuǎn)速的二次方成比例增加,所以用變頻器驅(qū)動(dòng)電動(dòng)機(jī)高速運(yùn)轉(zhuǎn)時(shí),振動(dòng)加大。變頻器是電子裝置,所以溫度對(duì)其壽命影響較大。通用變頻器的環(huán)境溫度一般-10~+50℃,如果能降低變頻器運(yùn)行溫度,就延長(zhǎng)了變頻器的使用壽命,性能也穩(wěn)定。變頻器發(fā)熱是由內(nèi)部損耗產(chǎn)生的,以主電路為主,約占總損耗的98%,控制電路占2%。
