Injini engenamabhulashi ye-Dcisakhiwo sayo sinengqondo, ijubane layo lizinzile kakhulu, ngakho-ke ngokuvamile, akuvamile ukulawulwa kwejubane elikhulu. Ngenxa yokuthi imoto inezinhlelo zokusebenza eziningi futhi ingasetshenziswa yimishini eminingi, kuyadingeka ukulungisa ijubane layo ngokwezikhathi ezahlukene. Kodwa indlela yokulawula ijubane ye-dc engenamabhulashi idinga wonke umuntu ukuba afunde, ukuze isetshenziswe ngokushesha:
1. Ngokulawula ukulandelana kokunikezwa amandla kwekhoyili, ikhoyili ephikisanayo ihlukaniswa ibe yiqembu bese kuthi amandla kagesi anikwe amandla ukuze kukhiqizwe insimu yamagnetic ohlangothini olufanayo.
2. Inani lezinsika zemoto ye-dc engenamabhulashi liyizintathu, ukuze i-“zinsika zikamazibuthe” ngayinye iqhutshwe ngokulandelana okuthile ukuze kufezwe umphumela wokujikeleza kwensimu kamazibuthe. Ngaphansi kwesenzo sensimu kamazibuthe, i-rotor kamazibuthe ohlala njalo ophakathi ihlale inomkhuba wokugcina insimu kamazibuthe isendaweni efanayo futhi izojikeleza nensimu kamazibuthe ejikelezayo.
I-H1H2H3 iyizinzwa ezintathu zeHholo ezibekwe endaweni yomoya yekhoyili yokuvuselela, esetshenziswa njengesici sokuthola insimu yamagnetic. I-voltage ingashintshwa ngokuya ngesiqondiso sensimu yamagnetic, futhi umphumela uyisignali yedijithali.
3. Ikhoyili ye-stator inikwa amandla ngokuya ngokulandelana okulandelayo, futhi insimu yamagnetic ye-rotor kanye nensimu yamagnetic ye-stator kumele zibe ne-Angle. Asikho isidingo sokwahlulela ukuthi i-motor ye-dc engenamabhulashi isanda kuqaliswa yini, kudingeka nje usebenzise umyalo olandelayo ngokuya ngesimo sokusebenza esithunyelwe yi-Hall sensor.
Umyalo wayo ukuthumela amabhangqa amathathu e-coil avuliwe futhi avaliwe, lawa maswishi atholakala nge-transistor.
Ukujikeleza kwe-BLDC yesigaba esithathu kungabonakala ngokunika amandla noma ngokusika ama-transistors amathathu ngokulandelana okuthile.
4. Njengoba i-rotor ijikeleza, amandla abangelwa yi-coil ngayinye asuka phezulu kakhulu aye ku-zero abuye abuye futhi. Ngoba lapho i-coil inikwe amandla ngakolunye uhlangothi, amandla e-electromotive abuyela emuva azovimba i-voltage ebuyela emuva, ngakho-ke ingxenye yegagasi le-trapezoidal izovela. I-voltage enhle nembi yengxenye ye-trapezoidal ye-zero iphambene, ngakho-ke isimo sokusebenza se-motor stator singanqunywa ngokuthola i-voltage enhle nembi ngemuva kwe-voltage comparator.
Njengoba iphuzu lika-zero liphakathi nendawo ye-trapezoid, ukujikeleza kwe-BLDC kungalawulwa ngemva kokuba isignali yokulawula yochungechunge lwesikhathi oluhambisanayo ikhishwe ngemuva kokubambezeleka okungu-30°. Le ndlela yokulawula ayidingi inzwa ye-Hall, futhi izintambo ezintathu zingashayela i-I-BLDC.Uma isimo segagasi sifanelekile, amajika amathathu e-voltage ekhoyili angatholakala ngokuhlanganisa i-voltage ngqo. Ngakho-ke i-motor ye-dc engenamabhulashi ingalawulwa.
5. Nquma indlela yokuqala, qala ngokunika amandla ikhoyili engezansi kuleyo ndlela, yenza i-rotor iphendukele endaweni yokuqala ngesikhathi esifushane, bese unika amandla injini ngokulandelana kwezenzo ezilandelayo.
Ukuze sithuthukise ukusebenza kahle kokusetshenziswa kwemoto ye-dc engenamabhulashi, sidinga ukufunda ukuthi ngokwezindawo ezahlukene zokusetshenziswa, ukulawula okuhlukile kanye nokulawulwa kwesivinini, ukuthuthukisa ukusebenza kahle kokusetshenziswa kwemoto, indlela yokulawula kanye nokulawulwa kwesivinini ingasetshenziswa ukulungisa isivinini.
