冷卻塔電機的正確安裝方法

冷卻塔電機的電機軸是長(cháng)軸，對找正要求不高，只需用直尺向下移動(dòng)即可。設備振動(dòng)大的原因基本上是廠(chǎng)家用的空心碳鋼軸。由于不平衡可能導致厚度不均勻和...

解決步進(jìn)電機定位問(wèn)題？

一般步進(jìn)電機的驅動(dòng)方向和脈沖信號都有一定的要求。比如第一個(gè)脈沖信號的上升或下降方向的驅動(dòng)要求在識別前幾微秒是不同的，否則會(huì )出現脈沖工作角度和...

解決抗干擾問(wèn)題是變頻器應用的關(guān)鍵！

變頻器是將工頻轉換成變頻功率的裝置，介于工頻和電氣設備之間。逆變器是典型的電力電子器件，其硬件核心是電力電子元件和微處理器芯片。電力電子元件...

步進(jìn)電機制造商需要做什么來(lái)開(kāi)發(fā)

許多投資者看中了步進(jìn)電機制造商的商機，導致市場(chǎng)上這類(lèi)制造商越來(lái)越多。那么，這種設備的廠(chǎng)商要想發(fā)展，應該做好什么呢？1.發(fā)展與創(chuàng )新步進(jìn)電機廠(chǎng)商...

電機傳動(dòng)為什么用高速電機驅動(dòng)低速設備？

偶然在路邊看到的柴油發(fā)電機的傳動(dòng)結構引起了人們對討論電機傳動(dòng)機構的興趣。電機產(chǎn)品是一種將電機能量轉化為機械能的動(dòng)力設備。電機的傳動(dòng)方式主要有...

變頻電機絕緣系統的優(yōu)點(diǎn)

變頻電機采用“專(zhuān)用變頻感應電機和變頻器”的交流調速方式，以其優(yōu)異的性能和經(jīng)濟性引領(lǐng)調速領(lǐng)域更新傳統調速方式。它給各行各業(yè)帶來(lái)的好消息是，它可...

工頻電機采用變頻起動(dòng)時(shí)必須考慮的問(wèn)題！

為了解決工頻籠型電動(dòng)機的起動(dòng)問(wèn)題，可以采用軟啟動(dòng)器或降壓起動(dòng)。但是附加設備多，控制環(huán)節復雜，沒(méi)有變頻器的供電方式簡(jiǎn)單靈活。只有這樣，一系列的...

步進(jìn)電機驅動(dòng)器問(wèn)答

如何使用步進(jìn)電機驅動(dòng)器？答：根據電機電流，使用大于或等于該電流的驅動(dòng)器。步進(jìn)電機是一種開(kāi)環(huán)控制電機，可以將電脈沖信號轉換成角位移或線(xiàn)位移。過(guò)...

步進(jìn)電機驅動(dòng)集成電路

機電產(chǎn)品的機械子系統采用多個(gè)步進(jìn)電機，它們需要消耗過(guò)大的電流以防失步，從而產(chǎn)生大量的熱量。主動(dòng)增益控制（自動(dòng)增益控制)采用一種簡(jiǎn)單的技術(shù)來(lái)解...

電機效率能否直接從電機電流來(lái)判斷？

這個(gè)話(huà)題是因為一個(gè)電機用戶(hù)的問(wèn)題：客戶(hù)原來(lái)使用的3級節能電機在一次節能改造中被企業(yè)生產(chǎn)的2級節能電機所取代，但是與直觀(guān)的電流數據相比，2級節...
