Njengento yokusebenza yedijithali, i-stepper motor isetyenziswa kakhulu kwinkqubo yokulawula intshukumo. Abasebenzisi abaninzi kunye nabahlobo ekusebenziseni ii-stepper motors, bavakalelwa kukuba i-motor isebenza ngobushushu obukhulu, intliziyo iyathandabuza, abazi ukuba le nto iqhelekile na. Enyanisweni, ubushushu yinto eqhelekileyo kwii-stepper motors, kodwa yeyiphi inqanaba lobushushu elithathwa njengeliqhelekileyo, kwaye unganciphisa njani ubushushu be-stepper motor?
Enye, ukuqonda isizathu sokuba i-stepper motor ifudumale.
Kuzo zonke iintlobo zeemoto ze-stepper, i-internal yenziwe yi-iron core kunye ne-winding coil. Ukumelana nokujika, amandla kuya kuvelisa ilahleko, ubungakanani bokulahleka kunye nokuxhathisa kwaye i-current ilingana nesikwere, oku sihlala sikubiza ngokuba yi-copper loss, ukuba i-current ayisiyo i-DC eqhelekileyo okanye i-sine wave, iya kuvelisa ilahleko ye-harmonic; i-core hysteresis eddy current effect, kwi-alternating magnetic field nayo iya kuvelisa ilahleko, ubungakanani bezinto, i-current, i-frequency, i-voltage enxulumene nayo, ebizwa ngokuba yi-iron loss. I-copper loss kunye ne-iron loss ziya kubonakala ngendlela yokuvelisa ubushushu, ngaloo ndlela zichaphazela ukusebenza kakuhle kwemoto.
Injini yokunyathela idla ngokulandela ukuchaneka kokubeka kunye nokukhupha i-torque, ukusebenza kakuhle kuphantsi, umbane ngokubanzi mkhulu, kwaye izinto eziphezulu ze-harmonic, ukuphindaphinda kombane kutshintshana ngesantya kunye notshintsho, ngoko ke iimoto zokunyathela zihlala zinemeko yobushushu, kwaye imeko imbi kakhulu kunemoto ye-AC eqhelekileyo.
Kwakhona, ulawulo lobushushu lwe-stepper motor ngaphakathi koluhlu olufanelekileyo.
Ubushushu bemoto obuvumelekileyo buxhomekeke kwinqanaba elingakanani, ikakhulu kwinqanaba lobushushu bangaphakathi bemoto. Ubushushu bangaphakathi abutshatyalaliswa de bube kubushushu obuphezulu (ngaphezulu kwe-130 degrees). Ngoko ke, ukuba ubushushu bangaphakathi abudluli kwi-130 degrees, imoto ayizukonakala, kwaye ubushushu bomphezulu buya kuba ngaphantsi kwe-90 degrees. Ke ngoko, ubushushu bomphezulu wemoto ye-stepper ye-70-80 degrees buqhelekile. Indlela elula yokulinganisa ubushushu nge-thermometer, unokugweba ngobuchule: ngesandla singachukumisa imizuzwana engaphezu kwe-1-2, kungabi ngaphezu kwe-60 degrees; ngesandla singachukunyiswa kuphela, malunga ne-70-80 degrees; amaconsi ambalwa amanzi akhawuleza aphembeke, angaphezulu kwe-90 degrees; ewe, ungasebenzisa nompu wobushushu ukuze ubone.
Ngokukodwa, i-stepper motor ifudumeza ngotshintsho lwesantya.
Xa usebenzisa iteknoloji yokuqhuba yangoku engaguqukiyo, i-stepper motor kwisantya esingaguqukiyo nesiphantsi, i-current iya kuhlala ingaguqukiyo ukuze igcine i-torque ephumayo ingaguqukiyo.
Xa isantya siphezulu ukuya kwinqanaba elithile, amandla angasemva ngaphakathi kwemoto ayaphakama, umbane uya kuncipha kancinci kancinci, kwaye ne-torque nayo iya kuncipha. Ke ngoko, ukuveliswa kobushushu ngenxa yokulahleka kobhedu kunxulumene nesantya.
Ukuveliswa kobushushu kudla ngokuba phezulu ngesantya esingashukumiyo nesiphantsi kwaye kube phantsi ngesantya esiphezulu. Kodwa utshintsho lokulahleka kwentsimbi (nangona incinci inxalenye) alunjalo, kwaye ubushushu bemoto bubonke buyimbumba yezi zimbini, ngoko ke oku kungasentla yimeko nje eqhelekileyo.
Impembelelo yobushushu
Ubushushu bemoto, nangona ngokubanzi bungachaphazeli ubomi bemoto, uninzi lwabathengi akufuneki banike ingqalelo. Nangona kunjalo, ubushushu obukhulu buya kuzisa iziphumo ezibi.
Njengeendawo zangaphakathi ze-coefficient yokwandiswa kobushushu bemoto yoxinzelelo olwahlukeneyo lwesakhiwo olubangelwa lutshintsho kwisithuba somoya wangaphakathi kunye notshintsho oluncinci luya kuchaphazela impendulo eguqukayo yemoto, isantya esiphezulu siya kuba lula ukuphulukana nenyathelo.
Omnye umzekelo kukuba ezinye izihlandlo azivumeli ukufudumeza kakhulu imoto, njengezixhobo zonyango kunye nezixhobo zokuvavanya ezichanekileyo. Ke ngoko, ubushushu bemoto kufuneka bulawulwe ngokuyimfuneko.
五、 ukunciphisa ubushushu bemoto.
Ukunciphisa ubushushu, kukunciphisa ukulahleka kobhedu kunye nokulahleka kwesinyithi. Ukunciphisa ukulahleka kobhedu kuneendlela ezimbini, ukunciphisa uxhathiso kunye nombane, nto leyo efuna ukukhethwa kokumelana okuncinci kunye nomlinganiselo wamandla ombane kangangoko kunokwenzeka ekukhetheni iimoto ezincinci, iimoto zesigaba esibini, ezingasetyenziswa kwiimoto zochungechunge azinyanzelekanga ukuba zihambelane neemoto.
Kodwa oku kudla ngokungqubana neemfuno ze-torque kunye nesantya esiphezulu.
Kuba i-motor ikhethiwe, kufuneka isebenzise ngokupheleleyo umsebenzi wolawulo lwe-half-current oluzenzekelayo lwe-drive kunye nomsebenzi we-offline, owokuqala uyawunciphisa ngokuzenzekelayo umbane xa i-motor ikwimeko engaguqukiyo, owokugqibela uyawunqumla nje umbane.
Ukongeza, i-drive eyahlulwe kakuhle ngenxa ye-current waveform ekufutshane ne-sinusoidal, i-harmonics encinci, ukufudumeza kwe-motor kuya kuba ncinci. Azikho iindlela ezininzi zokunciphisa ukulahleka kwentsimbi, inqanaba le-voltage linxulumene ne-motor ye-high-voltage drive, nangona iya kuzisa iimpawu zesantya esiphezulu zokuphucula, kodwa ikwazisa nokwanda kobushushu.
Ngoko ke, sifanele sikhethe inqanaba elifanelekileyo le-drive voltage, sithathela ingqalelo isantya esiphezulu, ukuthamba kunye nobushushu, ingxolo kunye nezinye izalathisi.
