Iyini i-brushless motor—-umgomo wokusebenza

I-brushless DC kagesi motor (i-BLDC motor noma i-BL motor) isebenzisa amadivaysi okushintsha i-semiconductor ukuze ibone i-electronic commutator, okungukuthi, amadivaysi okushintsha i-electronic esikhundleni se-commutator yendabuko kanye nebhulashi.Inobuhle bokuthembeka okuphezulu, ayikho inhlansi yokuhamba, umsindo ophansi wemishini. njalo njalo.Isetshenziswa kabanzi esihlalweni sokurekhoda sebanga eliphezulu, isiqophi sevidiyo, insimbi ye-elekthronikhi kanye nemishini ye-automation yehhovisi.

I-brushless DC motor yakhiwe ngerotha kazibuthe ehlala unomphela, i-multi-pole winding stator kanye nenzwa yendawo.Inzwa yendawo ngokuya ngokushintsha indawo ye-rotor, kanye nokulandelana okuthile kwesiguquli samanje esijikajikayo se-stator (okungukuthi ukuthola isigxobo kazibuthe se-rotor esihlobene nendawo yokuma kwe-stator. , futhi ekunqumeni indawo yesignali yenzwa yendawo, isifunda sokuguqulwa kwesignali ukulawula isekethe yokushintsha amandla, ngemva kokucubungula ngokuvumelana okuthile okuhlobene okunengqondo phakathi kweswishi yamanje evunguzayo).I-voltage yokusebenza yama-winding stator inikezwa isekethe yokushintsha kagesi elawulwayo. ngokukhishwa kwenzwa yendawo.

Kunezinhlobo ezintathu zezinzwa zokuma: ezizwela kazibuthe, i-photoelectric kanye ne-electromagnetic.

I-Brushless DC motor enenzwa yendawo ezwela kazibuthe, izingxenye zayo zezinzwa ezizwela kazibuthe (njengengxenye yehholo, i-diode ezwela kazibuthe, ishubhu yesigxobo ezwela kazibuthe, isimelasi esizwela kazibuthe noma isekethe ekhethekile ehlanganisiwe, njll.) kufakwe ku-stator, njll. ukuhlanganiswa ukuze kutholwe izinguquko zensimu kazibuthe ezibangelwa uzibuthe unomphela nokuzungezisa i-rotor.

I-brushless DC motor ene-photoelectric position sensor ifakwe inzwa ye-photoelectric endaweni ethile emhlanganweni we-stator, isikrini sifakwe ku-rotor, futhi umthombo wokukhanya uholwa noma i-bulb encane.Lapho i-rotor ijikeleza, ngenxa yendima ku-shutter, izingxenye ezizwelayo ku-stator zizokhiqiza amasiginali we-pulse ngezikhathi ezithile.

Kusetshenziswa inzwa ye-electromagnetic position sensor brushless dc motor, ikwizinzwa zikagesi ezifakwe ezingxenyeni ze-stator (njenge-coupling transformer, eduze nokushintsha, isekethe ye-resonance ye-LC, njll.), lapho isikhundla sikamagnetic rotor sishintsha, umphumela we-electromagnetic uzoba yenza inzwa ye-electromagnetic ikhiqize isignali yokushintsha imvamisa ephezulu (i-amplitude iyashintsha ngokuma kwe-rotor)

I-JIUYUAN inesipiliyoni seminyaka engaphezu kwengu-20 kui-brushless dc motor encane,i-rotor yangaphandle brushless dc motor,i-rotor yangaphakathi brushless dc motor,i-brushless dc motor enesilawuli noma idrayivu njll.
