Yintoni i-brushless motor--umgaqo osebenzayo

Imoto yombane ye-brushless DC (i-BLDC motor okanye i-BL motor) isebenzisa izixhobo zokutshintsha ze-semiconductor ukuqonda i-electronic commutator, oko kukuthi, izixhobo zokutshintsha zombane endaweni ye-commutator yendabuko kunye ne-brush. kwaye nangokunjalo.Isetyenziswa ngokubanzi kwisihlalo sokurekhoda kwibakala eliphezulu, irekhoda yevidiyo, isixhobo sombane kunye nezixhobo ezizenzekelayo zeofisi.

Brushless DC motor yenziwe ngerotor yemagnethi esisigxina, i-stator ye-poli eninzi ejikajikayo kunye nesivamvo sendawo. Uluvo lwendawo ngokotshintsho lwendawo ye-rotor, ecaleni kolandelelwano oluthile lwe-stator ejikajikayo yesiguquli sangoku (oko kukuthi, ukufumanisa i-rotor magnetic pole ngokunxulumene nendawo ye-stator ukujikoza. , kwaye ekumiseleni indawo yomqondiso wesivamvo sendawo, isiphaluka sokuguqulwa komqondiso ukulawula isiphaluka sokutshintsha amandla, emva kokucubungula ngokwengqiqo ethile yobudlelwane phakathi kokutshintshwa kwangoku okuguqukayo). ngesiphumo soluvo lwendawo.

Zintathu iindidi zezivamvo zokuma: i-magnetic-sensitive, photoelectric kunye ne-electromagnetic.

I-Brushless DC motor ene-magnetic-sensitive sensor position, i-sensor yayo ye-magnetic-sensitive sensor (efana ne-holo element, i-diode-sensitive diode, i-magnet-sensitive pole tube, i-resistor magnetic-sensitive okanye isekethe ekhethekileyo edibeneyo, njl. indibano yokufumanisa utshintsho lwemagnethi olubangelwa yimagnethi esisigxina kunye nokujikeleza kwe-rotor.

I-brushless DC motor ene-photoelectric sensor position ixhotyiswe nge-photoelectric sensor kwindawo ethile kwi-stator assembly, isikrini sifakwe kwi-rotor, kwaye umthombo wokukhanya ukhokelwa okanye i-bulb encinci.Xa i-rotor ijikeleza, ngenxa yendima yesivalo, amacandelo photosensitive kwi stator ziya kuphazamisana ukuvelisa imiqondiso ipulse ngamaxesha athile.

Ukusebenzisa i-electromagnetic sensor position sensor brushless dc motor, ikwi-electromagnetic sensors zifakwe kumacandelo estator (ezifana ne-coupling transformer, kufutshane nokutshintsha, i-LC resonance circuit, njl. yenza inzwa ye-electromagnetic ivelise umqondiso wokumodareyitha okuphakamileyo (utshintsho lwe-amplitude kunye nesikhundla se-rotor)

I-JIUYUAN ineminyaka engaphezu kwama-20 yamavaencinci brushless dc motor,i-rotor yangaphandle brushless dc motor,i-rotor yangaphakathi brushless dc motor,i-brushless dc motor enomlawuli okanye ukuqhuba njl.
