變頻器常見(jiàn)過(guò)流、過(guò)載類(lèi)故障分析

ABB變頻器以其性能穩定，功能豐富的選項擴展功能豐富、靈活的編程環(huán)境，優(yōu)良的扭矩特性和制作其使用適應性使其在高端變頻器市場(chǎng)占有非常重要的地位...

電機斷相運行的原因及分析

根據電機不同的接線(xiàn)方式，在不同的負載下，斷相運行的電流也不同，因此采用的保護方式也不同。例如，Y型連接的電機異相運行時(shí)，其電機相電流等于線(xiàn)電...

教你如何認識電機模型

如果對電機有所了解，可以通過(guò)看模型來(lái)分析電機參數，通過(guò)建立的模型就可以知道自己想要哪種類(lèi)型的電機，電機的參數有哪些?，F在，油泵電機制造商將教...

淺談電機轉軸精車(chē)的控制

我們談到了軸的粗加工。粗加工是軸精加工的基礎。需要精加工的零件要留有足夠的加工余量，以保證正常的精加工。精車(chē)要求高，要由熟練工人在更精密的車(chē)...

為什么同一個(gè)電機的平行纏繞電磁線(xiàn)規格不能相差太多？

電機產(chǎn)品的繞組包括成型繞組和分散繞組。模壓繞組使用扁銅線(xiàn)，一般只使用單一規格的電磁線(xiàn)；對于散繞，其靈活性比較高，可以根據實(shí)際導電截面要求選擇...

2021年7月1日是時(shí)間節點(diǎn) 這種永磁電機必須貼上能效標簽！

能效為了給用戶(hù)和消費者提供必要的購買(mǎi)決策信息，引導和幫助消費者選擇節能、節能的產(chǎn)品，國家實(shí)行能效標識管理制度，即在耗能產(chǎn)品或其小包裝上，使用...

三相異步電動(dòng)機的拆裝方法

當三相異步電動(dòng)機出現一些故障或需要清理時(shí)，每個(gè)人都需要拆卸和組裝電動(dòng)機。以下小系列將介紹電機的拆裝方法，大家可以一起學(xué)習。拆卸時(shí)，需要用工具...

冷卻塔電機的溫升、冷態(tài)、熱態(tài)是什么意思

為了保證冷卻塔電機的供應和維護質(zhì)量，規范采購、維護和退貨程序，保證合理選擇、及時(shí)維護和正確使用，實(shí)現電機安全、經(jīng)濟、高效運行，取得更大的成績(jì)...

定子不變的情況下電機上轉子槽數有什么性能？

在前面的文章中，我們談到了可控電源對轉子設計的影響，即通過(guò)變頻控制來(lái)抑制電機諧波轉矩對起動(dòng)性能的負面影響，設計中幾乎不需要電機起動(dòng)問(wèn)題。轉子...

無(wú)刷步進(jìn)電機哪個(gè)廠(chǎng)家最好？

“無(wú)刷步進(jìn)電機？是那種小型步進(jìn)電機嗎？”前幾次，無(wú)刷步進(jìn)電機制造商邊肖被機電小白問(wèn)到這個(gè)問(wèn)題。今天，無(wú)刷步進(jìn)電機制造商推出了一款飛機模型無(wú)刷...
