直流電機控制原理

直流電機广东快乐十分的控制原理,要讓電機轉動起來,首先控制部就根據hall-sensor感應到的電機轉子所在位置,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,inverter中之AH、BH、CH(這些稱為上臂功率晶體管)及AL、BL、CL(這些稱為下臂功率晶體管),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。
