描述

1、變頻器功率按所帶的負載功率選取。多大功率電機就選多大的功率的變頻器。大一規(guī)格也可以。

2.、變頻器型號不同用途選不同的變頻器。例如有通用的變頻器，有風機水泵專用的變頻器，有機床主軸專用的變頻器。等等。

3.、負載慣性大的，要同時選擇制動單元和制動電阻。

4、查電動機的銘牌額定電流，(沒有銘牌時測出額定電流).變頻器的額定電流比電動機的最大運行電流大就可以了。

變頻器（Variable-frequencyDrive，VFD）是應用變頻技術與微電子技術，通過改變電機工作電源頻率方式來控制交流電動機的電力控制設備。變頻器主要由整流（交流變直流）、濾波、逆變（直流變交流）、制動單元、驅動單元、檢測單元微處理單元等組成。變頻器靠內(nèi)部IGBT的開斷來調(diào)整輸出電源的電壓和頻率，根據(jù)電機的實際需要來提供其所需要的電源電壓，進而達到節(jié)能、調(diào)速的目的，另外，變頻器還有很多的保護功能，如過流、過壓、過載保護等等。隨著工業(yè)自動化程度的不斷提高，變頻器也得到了非常廣泛的應用。
