EC電機bai是三相交流永磁同步電機。EC 電機電源為直流電源、內置直流變交流（通過六個逆變模塊）、采用轉子位置反饋、三相交流、永磁、同步電機。

EC電機為內置智能控制模塊的直流無刷式免維護型電機，自帶RS485輸出接口、0-10V傳感器輸出接口、4-20mA調速開關輸出接口、報警裝置輸出接口及主從信號輸出接口。該產品具有高智能、高節能、高效率、壽命長、振動小、噪聲低以及可連續不間斷工作等特點。

無刷直流電機由于省去了勵磁用的集電環和電刷，在結構上大大簡化。同時不但改善了電機的工藝性，而且電機運行的機械可靠性大為增強，壽命增加。
同時氣隙磁密可大大提高，電機指標可實現*佳設計，其直接效果就是電機體積縮小，重量減輕。不僅如此，較其它電機而言，還具有非常優異的控制性能。這是因為：其一，由于永磁材料的高性能而使電機的力矩常數、轉矩慣量比、功率密度等大大提高。通過合理設計又能使轉動慣量、電氣及機械時間常數等指標大大降低，作為伺服控制性能的主要指標有了很大改善。其二，現代永磁磁路的設計已較完善，加上永磁材料的矯頑力高，因而永磁電機的抗電樞反應及其抗去磁的能力大大加強，電機的控制參量隨外部擾動影響大大減小。其三，由于用永磁體取代了電勵磁，減少了勵磁繞組及勵磁磁場的設計，因而減少了勵磁磁通、勵磁繞組電感、勵磁電流等諸多參數，從而直接減少了可控變量或參量。綜合以上各因素可以說永磁電機具有優異的可控性。

無刷直流電動機需要矩形波電流，逆變器持續運行時的電流額定值指的就是這個矩形波的峰值。感應電機需要正弦波電流，逆變器持續運行時的電流額定值一般指的是這個正弦波的有效值。為保持逆變器對電動機電流的控制能力，逆變器直流電壓與電動機感應電動勢間應有足夠的差值。因此無刷直流電動機梯形波感應電動勢和感應電動機正弦波感應電動勢可以達到的峰值都受到逆變器直流電壓的限制。在這種情況下，若假定無刷直流電動機和感應電動機電流的峰值相等，則前者功率輸出要比后者高出33%，也就是說，同一臺整流器/逆變器可以驅動比感應電機輸出功率高出33%的無刷直流電動機。

無刷直流電動機是采用半導體開關器件來實現電子換向的，即用電子開關器件代替傳統的接觸式換向器和電刷。它具有可靠性高、無換向火花、機械噪聲低等優點，廣泛應用于高檔錄音座、錄像機、電子儀器及自動化辦公設備中。
無刷直流電動機由永磁體轉子、多極繞組定子、位置傳感器等組成。位置傳感按轉子位置的變化，沿著一定次序對定子繞組的電流進行換流（即檢測轉子磁極相對定子繞組的位置，并在確定的位置處產生位置傳感信號，經信號轉換電路處理后去控制功率開關電路，按一定的邏輯關系進行繞組電流切換）。定子繞組的工作電壓由位置傳感器輸出控制的電子開關電路提供。

位置傳感器有磁敏式、光電式和電磁式三種類型。
采用磁敏式位置傳感器的無刷直流電動機，其磁敏傳感器件（例如霍爾元件、磁敏二極管、磁敏詁極管、磁敏電阻器或專用集成電路等）裝在定子組件上，用來檢測永磁體、轉子旋轉時產生的磁場變化。
采用光電式位置傳感器的無刷直流電動機，在定子組件上按一定位置配置了光電傳感器件，轉子上裝有遮光板，光源為發光二極管或小燈泡。轉子旋轉時，由于遮光板的作用，定子上的光敏元器件將會按一定頻率間歇間生脈沖信號。
采用電磁式位置傳感器的無刷直流電動機，是在定子組件上安裝有電磁傳感器部件（例如耦合變壓器、接近開關、LC諧振電路等），當永磁體轉子位置發生變化時，電磁效應將使電磁傳感器產生高頻調制信號（其幅值隨轉子位置而變化）。

直流電機具有響應快速、較大的起動轉矩、從零轉速至額定轉速具備可提供額定轉矩的性能，但直流電機的優點也正是它的缺點，因為直流電機要產生額定負載下恒定轉矩的性能，則電樞磁場與轉子磁場須恒維持90°，這就要藉由碳刷及整流子。碳刷及整流子在電機轉動時會產生火花、碳粉因此除了會造成組件損壞之外，使用場合也受到限制。交流電機沒有碳刷及整流子，免維護、堅固、應用廣，但特性上若要達到相當于直流電機的性能須用復雜控制技術才能達到。現今半導體發展迅速功率組件切換頻率加快許多，提升驅動電機的性能。微處理機速度亦越來越快，可實現將交流電機控制置于一旋轉的兩軸直交坐標系統中，適當控制交流電機在兩軸電流分量，達到類似直流電機控制并有與直流電機相當的性能。

直流無刷電機是同步電機的一種，也就是說電機轉子的轉速受電機定子旋轉磁場的速度及轉子極數(p)影響。在轉子極數固定情況下，改變定子旋轉磁場的頻率就可以改變轉子的轉速。直流無刷電機即是將同步電機加上電子式控制(驅動器)，控制定子旋轉磁場的頻率并將電機轉子的轉速回授至控制中心反復校正，以期達到接近直流電機特性的方式。也就是說直流無刷電機能夠在額定負載范圍內當負載變化時仍可以控制電機轉子維持一定的轉速。

要讓電機轉動起來，首先控制部就必須根據hall-sensor感應到的電機轉子目前所在位置，然后依照定子繞線決定開啟(或關閉)換流器(inverter)中功率晶體管的順序，使電流依序流經電機線圈產生順向(或逆向)旋轉磁場，并與轉子的磁鐵相互作用，如此就能使電機順時/逆時轉動。當電機轉子轉動到hall-sensor感應出另一組信號的位置時，控制部又再開啟下一組功率晶體管，如此循環電機就可以依同一方向繼續轉動直到控制部決定要電機轉子停止則關閉功率晶體管(或只開下臂功率晶體管)；要電機轉子反向則功率晶體管開啟順序相反。
