Imoto yestepperumgaqo wokusebenza
Ngokwesiqhelo, i-rotor yemoto yimagnethi esisigxina. Xa umsinga udlula kwi-stator winding, i-stator winding ivelisa i-vector magnetic field. Le magnethi iqhuba i-rotor ukuba ijikeleze nge-engile ukuze icala le-rotor's pair of magnetic fields lihambelane nelo le-stator's field. Xa i-vector magnetic field ye-stator ijikeleza nge-engile.
Imoto yestepperluhlobo lwemoto yokungenisa, umgaqo wayo wokusebenza kukusetyenziswa kwesekethe ye-elektroniki, umbane othe ngqo ungene kumbane okwabelana ngexesha, umbane wokulawula ixesha lezigaba ezininzi, kunye nalo mbane wokubonelela ngombane we-stepper motor, i-stepper motor ingasebenza ngokufanelekileyo, umqhubi ngowemoto ye-stepper motor yokubonelela ngombane okwabelana ngexesha, umlawuli wexesha lezigaba ezininzi.
Igalelo ngalinye liyi-pulse yombane, imoto ijikeleza i-engile phambili inyathelo elinye. Ukuphuma kwayo kwe-angular displacement kuhambelana nenani lee-pulse input, isantya sihambelana ne-pulse frequency. Tshintsha ulandelelwano lwe-winding energization, imoto iya kubuyela umva. Ngoko unokulawula inani lee-pulses, i-frequency kunye nolandelelwano lwe-enhancement phase nganye ye-motor winding ukulawula ukujikeleza kwe-stepper motor.
Ukuchaneka kwemoto ye-stepper jikelele yi-3-5% ye-angle yokunyathela, kwaye ayiqokeleli.
I-torque ye-stepper motor iya kuncipha njengoko isantya sisanda. Njengoko i-stepper motor ijikeleza, i-inductance yesigaba ngasinye sokujika kwe-motor iya kwenza i-reverse electric potential; okukhona i-frequency iphezulu, kokukhona i-reverse electric potential inkulu. Phantsi kwesenzo sayo, i-motor ene-frequency (okanye isantya) iyanda kwaye i-phase current iyancipha, nto leyo ekhokelela ekunciphiseni i-torque.
Injini ye-Stepper ingasebenza ngokuqhelekileyo ngesantya esiphantsi, kodwa ukuba iphezulu kunesantya esithile ayizukuqalisa, kwaye ihamba nesandi somlozi.
Imoto yeStepper inepharamitha yobuchwephesha: isantya sokuqala esingenamthwalo, oko kukuthi, i-stepper motor kwimeko yesantya sokuphefumla esingenamthwalo ingaqaliswa ngokuqhelekileyo, ukuba isantya sokuphefumla siphezulu kunexabiso, i-motor ayikwazi ukuqala ngokuqhelekileyo, inokwenzeka ngaphandle kwenyathelo okanye ukuvala.
Kwimeko yomthwalo, isantya sokuqala kufuneka sibe phantsi. Ukuba i-motor ifuna ukujikeleza ngesantya esiphezulu, isantya sokuphefumla kufuneka sibe nenkqubo yokukhawulezisa, oko kukuthi, isantya sokuqala siphantsi, size sinyuke siye kwisantya esiphezulu esifunekayo (isantya se-motor ukusuka kwisantya esiphantsi ukuya kwisantya esiphezulu) kwisantya esithile.
Kutheni usenzaiimoto ze-stepperkufuneka kulawulwe ngokunciphisa isantya
Isantya semoto ye-stepper sixhomekeke kwi-pulse frequency, inani lamazinyo e-rotor kunye nenani lee-beats. Isantya sayo se-angular sihambelana ne-pulse frequency kwaye sihambelana ngexesha ne-pulse. Ke ngoko, ukuba inani lamazinyo e-rotor kunye nenani lee-beats ezibalekayo ziqinisekile, isantya esifunekayo sinokufunyanwa ngokulawula i-pulse frequency. Ekubeni i-stepper motor iqalwa ngoncedo lwe-synchronous torque yayo, i-start frequency ayiphezulu ukuze ingaphulukani nenyathelo. Ingakumbi njengoko amandla enyuka, ububanzi be-rotor buyanda, i-inertia iyanda, kwaye i-start frequency kunye ne-maximum running frequency zinokuhluka kangangezihlandlo ezilishumi.
Iimpawu zokuqala ze-stepper motor ukuze i-stepper motor iqale ingafikeleli ngqo kwi-frequency yokusebenza, kodwa ibe nenkqubo yokuqalisa, oko kukuthi, ukusuka kwisantya esiphantsi inyuka kancinci ukuya kwisantya sokusebenza. Yeka xa i-frequency yokusebenza ingenakwehla ngoko nangoko iye kwi-zero, kodwa ibe nokunciphisa isantya kancinci kancinci ukuya kwi-zero.
Ngoko ke, ukusebenza kwe-stepper motor ngokubanzi kufuneka kudlule kwisantya esilinganayo, isantya esifanayo, isantya esiphantsi, inkqubo yokukhawulezisa kunye nesantya esiphantsi ibe mfutshane kangangoko, ixesha lesantya esingapheliyo libe lide kangangoko kunokwenzeka. Ingakumbi kumsebenzi ofuna impendulo ekhawulezileyo, ixesha elifunekayo ukubaleka ukusuka kwindawo yokuqala ukuya esiphelweni lelona lifutshane, ekufuneka lifune inkqubo emfutshane yokukhawulezisa kunye nesantya esiphantsi, kunye nesantya esiphezulu kwisantya esingapheliyo.
I-algorithm yokukhawulezisa kunye nokuthomalalisa yindlela enye yetekhnoloji ephambili kulawulo lokuhamba, kwaye yenye yezinto ezibalulekileyo zokufezekisa isantya esiphezulu kunye nokusebenza kakuhle. Kulawulo lwemizi-mveliso, kwelinye icala, inkqubo yokucubungula kufuneka ibe bushelelezi kwaye izinzile, inempembelelo encinci yokuguquguquka; kwelinye icala, ifuna ixesha lokuphendula ngokukhawuleza kunye nokuphendula ngokukhawuleza. Kwisiseko sokuqinisekisa ukuchaneka kolawulo ukuphucula ukusebenza kakuhle kokucubungula, ukufezekisa intshukumo yoomatshini ethambileyo nezinzileyo, yindlela yokusebenza kwangoku kwemizi-mveliso ebekukusombulula ingxaki ephambili. Ii-algorithms zokukhawulezisa kunye nokuthomalalisa ezisetyenziswa rhoqo kwiinkqubo zolawulo lokuhamba kwangoku ziquka: ukukhawulezisa kunye nokuthomalalisa kwe-trapezoidal curve, ukukhawulezisa kunye nokuthomalalisa kwe-exponential curve, ukukhawulezisa kunye nokuthomalalisa kwe-S-shaped curve, ukukhawulezisa kunye nokuthomalalisa kwe-parabolic curve, njl.
Ukukhawulezisa kunye nokuhla kwesantya seTrapezoidal curve
Inkcazo: Ukukhawulezisa/ukunciphisa isantya ngendlela ethe tye (ukukhawulezisa/ukunciphisa isantya ukusuka kwisantya sokuqala ukuya kwisantya ekujoliswe kuso) ngomlinganiselo othile
Ifomula yokubala: v(t)=Vo+at
Iingenelo kunye nokungalungi: I-Trapezoidal curve ibonakaliswa yi-algorithm elula, ithatha ixesha elincinci, impendulo ekhawulezayo, ukusebenza kakuhle kunye nokuphunyezwa okulula. Nangona kunjalo, izigaba zokukhawulezisa kunye nokuhla kwesantya ezifanayo azihambelani nomthetho wotshintsho lwesantya se-stepper motor, kwaye indawo yokutshintsha phakathi kwesantya esiguquguqukayo kunye nesantya esifanayo ayinakuba lula. Ke ngoko, le algorithm isetyenziswa kakhulu kwizicelo apho iimfuno zenkqubo yokukhawulezisa kunye nokuhla kwesantya zingekho phezulu.
Ukukhawuleziswa kwejika elibonakalayo kunye nokwehla kwesantya
Inkcazo: Ithetha ukukhawulezisa kunye nokunciphisa isantya ngomsebenzi we-exponential.
Isalathisi sovavanyo lokukhawulezisa kunye nokuhla kwesantya solawulo:
1. Impazamo yendlela yokuqhuba umatshini kunye nendawo kufuneka ibe ncinci kangangoko kunokwenzeka
2. Inkqubo yokuhamba komatshini igudileyo, i-jitter incinci, kwaye impendulo ikhawuleza
3, i-algorithm yokukhawulezisa kunye nokuthomalalisa kufuneka ibe lula kangangoko, ibe lula ukuyisebenzisa, kwaye ikwazi ukuhlangabezana neemfuno zolawulo lwexesha langempela
