Iqhaza lama-Hall Effect ICs ku-BLDC Motor
Ama-IC womphumela wehholo adlala indima ebalulekile kumamotho e-BLDC ngokuthola indawo yerotha, okuvumela ukulawula okunembile kwesikhathi sokugeleza kwamanje kumakhoyili e-stator.
I-BLDC MotorLawula
Njengoba kuboniswe emfanekisweni, i-BLDC motor control system ibona indawo yerotor ejikelezayo bese iyalela umshayeli wesilawuli semoto ukuthi ashintshe okwamanje kukhoyili, ngaleyo ndlela aqalise ukujikeleza kwemoto.
Ukutholwa kwendawo ye-rotor yingxenye ebalulekile yale nqubo.
Ukwehluleka ukuthola indawo ye-rotor kuvimbela isigaba sokunika amandla ukuthi sisetshenziswe ngesikhathi esinembile esidingekayo ukuze kugcinwe ubudlelwano obuhle be-flux phakathi kwe-stator ne-rotor, okuholela ekukhiqizweni kwetorque encane.
Okubi kakhulu, injini ngeke ijikeleze.
Ama-IC womphumela wehholo athola indawo ye-rotor ngokushintsha i-voltage ephumayo lapho ebona ukuguquguquka kazibuthe.
I-Hall Effect IC Ukubekwa ku-BLDC Motor
Njengoba kubonisiwe isibalo, ama-IC womphumela weHholo amathathu asatshalaliswa ngokulinganayo kumjikelezo ongu-360° (i-engeli kagesi) werotha.
Amasiginali okukhiphayo wama-IC womphumela we-Hall amathathu athola ukushintsha kozibuthe we-rotor ngokuhlangana njalo ngo-60° wokuzungezisa kumjikelezo ongu-360° werotha.
Lokhu kuhlanganiswa kwamasignali kushintsha amandla akhona ekhoyili. Esigabeni ngasinye (U, V, W), i-rotor inikezwa amandla futhi izungeza i-120° ukuze ikhiqize isigxobo sika-S.
Ukukhanga kazibuthe kanye ne-repulsion okukhiqizwa phakathi kwe-rotor nekhoyili kubangela ukuthi i-rotor ijikeleze.
Ukudluliswa kwamandla ukusuka kumjikelezo wedrayivu ukuya kukhoyili kulungiswa ngokuya kwesikhathi sokuphuma kwe-Hall effect IC ukuze kuzuzwe ukulawula okuzuzisayo okusebenzayo.
Yini enikezayobrushless vibration motorsimpilo ende? Ukusebenzisa I-Hall Effect Ukushayela I-Brushless Motors. Sisebenzisa i-Hall Effect ukubala indawo yemoto bese sishintsha isignali yokushayela ngendlela efanele.
Lezi zithombe zibonisa ukuthi isignali yedrayivu ishintsha kanjani ngokuphuma kwezinzwa ze-Hall Effect.
Xhumana Nochwepheshe Bakho Abaholayo
Sikusiza ukuthi ugweme izingibe zokuletha ikhwalithi futhi wazise isidingo sakho se-micro brushless motor, ngesikhathi nangesabelomali.
