I-brushless DC motor(i-BLDC) iyinjini esebenza kahle kakhulu, enomsindo ophansi, esebenza isikhathi eside esetshenziswa kakhulu emikhakheni eyahlukene, njengokuzenzakalela kwezimboni, amathuluzi kagesi, izimoto zikagesi, njll. Ukulawulwa kwesivinini kuwumsebenzi obalulekile we-brushless DC motor. ukulawula. Izindlela ezimbalwa ezijwayelekile zokulawula isivinini semoto ye-brushless DC zizokwethulwa ngezansi.
1. Ukulawulwa kwesivinini sikagesi
Ukulawulwa kwesivinini sikagesi kuyindlela elula yokulawula isivinini, elawula isivinini semoto ngokushintsha i-voltage kagesi we-DC. Lapho i-voltage ikhuphuka, ijubane lemoto nalo lizokhula; ngokuphambene, lapho i-voltage iyancipha, ijubane lemoto nalo lizokwehla. Le ndlela ilula futhi kulula ukuyisebenzisa, kodwa kumamotho anamandla amakhulu, umphumela wokulawulwa kwesivinini se-voltage awulungile, ngoba ukusebenza kahle kwemoto kuzokwehla njengoba i-voltage ikhula.
2. Ukulawulwa kwejubane le-PWM
Ukulawulwa kwejubane kwe-PWM (Pulse Width Modulation) kuyindlela evamile yokulawula isivinini semoto, elawula isivinini semoto ngokushintsha umjikelezo womsebenzi wesignali ye-PWM. Lapho umjikelezo womsebenzi wesignali ye-PWM ukhula, i-voltage evamile yemoto nayo izokhuphuka, ngaleyo ndlela ikhulise isivinini semoto; ngokuphambene, lapho umjikelezo womsebenzi wesignali ye-PWM wehla, ijubane lemoto nalo lizokwehla. Le ndlela ingafinyelela ukulawulwa kwejubane okunembile futhi ilungele ama-motor e-DC angenawo amandla ahlukahlukene.
3. Ukulawulwa kwejubane lempendulo yenzwa
Amamotho e-Brushless DC ngokuvamile afakwe izinzwa zaseHholo noma izishumeki. Ngempendulo yenzwa yesivinini semoto kanye nolwazi lokuma, isilawuli sesivinini esivaliwe singafinyelelwa. Ukulawulwa kwejubane elivaliwe kungathuthukisa ukuqina nokunemba kwemoto, futhi kufanelekile izikhathi ezinezidingo zejubane eliphezulu, njengamathuluzi emishini namasistimu ezishintshayo.
4. Ukulawulwa kwesivinini sempendulo yamanje
Ukulawulwa kwesivinini sempendulo yamanje kuyindlela yokulawula isivinini esuselwe kumotho wamanje, olawula isivinini semoto ngokuqapha amandla amanje emoto. Lapho umthwalo we-motor ukhula, i-current izophinde ikhule. Ngalesi sikhathi, isivinini esizinzile se-motor singagcinwa ngokwandisa i-voltage noma ukulungisa umjikelezo womsebenzi wesignali ye-PWM. Le ndlela ifanele izimo lapho umthwalo wemoto ushintsha kakhulu futhi ungafinyelela ukusebenza okungcono kokuphendula okuguquguqukayo.
5. Ukuma kwendawo kazibuthe engenazinzwa kanye nokulawulwa kwesivinini
I-Sensorless magnetic field positioning regulation ubuchwepheshe obuthuthukisiwe bokulawula isivinini obusebenzisa isilawuli se-elekthronikhi esingaphakathi kwemoto ukuqapha nokulawula inkambu kazibuthe yemoto ngesikhathi sangempela ukuze kuzuzwe ukulawula okunembayo kwejubane lemoto. Le ndlela ayidingi izinzwa zangaphandle, yenza kube lula ukwakheka kwemoto, ithuthukisa ukuthembeka nokuzinza, futhi ifaneleka ezimweni lapho umthamo nesisindo semoto siphezulu.
Kuzinhlelo zokusebenza ezisebenzayo, izindlela eziningi zokulawula isivinini zivame ukuhlanganiswa ukuze kuzuzwe ukulawulwa kwezimoto okunembe kakhudlwana futhi kuzinzile. Ngaphezu kwalokho, uhlelo olufanele lokulawula isivinini lungakhethwa ngokuya ngezinhlelo zokusebenza ezithile kanye nezidingo. Ubuchwepheshe bokulawula isivinini se-brushless DC motors bukhula njalo futhi buthuthuka. Ngokuzayo, izindlela ezintsha zokulawula isivinini zizovela ukuze zihlangabezane nezidingo zokulawulwa kwezimoto emikhakheni ehlukene.
