Using The Hall Effect to Drive Brushless Motors

Usebenzisa umphumela wehholo ukushayela ama-motors angenamkhawulo

Indima Yomphumela Wehholo I-HALL ICS emotweni ye-BLDC

Umphumela we-Hall ics udlala indima ebalulekile kuma-BLDC motors ngokuthola isikhundla se-rotor, evumela ukulawulwa okuqondile kwesikhathi sokugeleza kwamanje ku-stator coils.

Bldc motorUkuphatha

Njengoba kukhonjisiwe kwisibalo, uhlelo lwe-Bldc Motor Control System lubona isikhundla se-rotor ejikelezayo futhi kamuva liyalela umshayeli olawulayo wezimoto ukuthi ashintshe ama-Coil, ngaleyo ndlela aqale ukujikeleza kwezimoto.

Ukutholwa kwesikhundla se-rotor kuyingxenye ebalulekile yale nqubo.

Ukwehluleka ukuthola isikhundla se-rotor kuvimbela isigaba sokunikeza amandla kusuka ekusetshenzisweni kwesikhathi esiqondile esidingekayo ukuze silondoloze ubudlelwano obuhle kakhulu be-stator kanye ne-rotor, okuholela ekukhiqizweni kwe-torque suffoptimal.

Kubi kakhulu, imoto ngeke ijikeleze.

I-Hall Effect ICS ithola isikhundla se-rotor ngokushintsha amandla abo okukhipha lapho bethola i-flux kazibuthe.

I-Hall Effect IC Ukubekwa e-BLDC motor

Njengoba kukhonjisiwe lesi sibalo, ama-ICS ama-ICS amathathu asatshalaliswa ngokulinganayo ku-360 ° (engela kagesi) ukujikeleza kwe-rotor.

Izimpawu zokuphuma zalo mphumela wehholo le-HALL ezithola ushintsho olukhulu lwamandla ka-rotor ngokuhambisana njalo nge-60 ° yokujikeleza ngokujikeleza kwe-rotor engu-360 ° ye-rotor.

Le nhlanganisela yezimpawu ishintsha ukugeleza kwamanje ngekhoyili. Esigabeni ngasinye (u, v, w), i-rotor inamandla futhi ijikeleze u-120 ° ukukhiqiza i-S Pole / n Pole.

Ukukhanga kazibuthe nokuphindisela okwenziwe phakathi kwe-rotor nekhoyili kubangele ukuba i-rotor ijikeleze.

Ukudluliswa kwamandla kusuka ku-drive Circuit kuya kwikhoyili kuyalungiswa ngokuya ngesikhathi sokuphuma kwe-Hall Effect Ic ukufezekisa ukusebenza okusebenzayo kokujikeleza.

Yini enikezaUkudlidliza Ama-Volors MotorsImpilo ende? Usebenzisa umphumela wehholo ukushayela ama-motor angenamkhawulo. Sisebenzisa umphumela wehholo ukubala isikhundla semoto futhi sishintshe isiginali ye-drive ngokufanele.

Lezi zithombe zibonisa ukuthi isinali ye-drive ishintsha kanjani ngokuphuma okuvela ezinzwa ezisebenza ngehholo.
