Injini yokunyathelaumgaqo wokusebenza
Ngokuqhelekileyo, i-rotor yemoto yimagnethi esisigxina. Xa ikhoyo ngoku ihamba nge-stator winding, i-stator winding ivelisa i-vector magnetic field. Le ntsimi yamagnetic iqhuba i-rotor ukuba ijikeleze nge-engile ukwenzela ukuba isalathiso se-rotor ye-magnetic fields ihambelane nentsimi ye-stator. Xa i-vector magnetic field ye-stator ijikeleza nge-angle.
Injini yokunyathelaluhlobo lwemoto yokungenisa, umgaqo wayo wokusebenza kukusetyenziswa kwesekethe ye-elektroniki, umbane othe ngqo kwi-time-sharing power supply, i-multiphase timeing control current, nale yangoku ye-stepper motor power supply, i-stepper motor inokusebenza ngokufanelekileyo, umqhubi weye-stepper motor-time-sharing power supply, multiphase time controller.
Igalelo ngalinye i-pulse yombane, i-motor ijikelezisa i-engile phambili inyathelo elinye. Isiphumo sayo sokufuduswa kwe-angular silingana nenani legalelo le-pulses, isantya silingana ne-pulse frequency. Guqula ulandelelwano lwamandla omoya, i-motor iya kubuya umva. Ke unokulawula inani lee-pulses, frequency kunye nomyalelo wokwenza amandla kwinqanaba ngalinye le-motor winding ukulawula ukujikeleza kwe-stepper motor.
Ukuchaneka kwe-motor stepper jikelele yi-3-5% ye-angle yokunyathela, kwaye ayiqokeleli.
I-torque ye-stepper motor iya kuncipha njengoko isantya sikhula. Njengoko i-motor stepper ijikeleza, i-inductance yesigaba ngasinye se-motor winding iya kwenza amandla ombane angasemva; Okukhona uphezulu amaza ombane, kokukhona amandla ombane angasemva. Ngaphantsi kwesenzo sayo, i-motor ene-frequency (okanye isantya) iyanda kwaye isigaba sangoku siyancipha, okukhokelela ekunciphiseni kwe-torque.
I-Stepper motor inokusebenza ngesantya esisezantsi, kodwa ukuba iphezulu kunesantya esithile ayiyi kuqalisa, kwaye ikhatshwa sisandi somlozi.
I-Stepper motor ine-parameter yobuchwephesha: akukho mthwalo wokuqalisa ukuhamba, oko kukuthi, i-motor ye-stepper kwimeko yokungabikho komthwalo we-pulse frequency inokuqaliswa ngokuqhelekileyo, ukuba i-pulse frequency iphezulu kunexabiso, i-motor ayikwazi ukuqala ngokuqhelekileyo, inokuthi yenzeke ngaphandle kwenyathelo okanye ukuthintela.
Kwimeko yomthwalo, i-frequency yokuqala kufuneka ibe ngaphantsi. Ukuba i-motor izakufezekisa ukujikeleza kwesantya esiphezulu, i-pulse frequency kufuneka ibe nenkqubo yokukhawulezisa, oko kukuthi, i-frequency yokuqala iphantsi, kwaye inyuke iye kwi-frequency ephezulu efunekayo (isantya semoto ukusuka kwisantya esisezantsi ukuya kwisantya esiphezulu) kwisantya esithile.
Kutheni usenzaiinjini zokunyathelakufuneka ilawulwe ngokunciphisa isantya
Isantya se-stepper motor sixhomekeke kwi-pulse frequency, inani lamazinyo e-rotor kunye nenani lokubethelwa. Isantya salo se-angular silingana ne-pulse frequency kwaye ihambelana ngexesha kunye ne-pulse. Ngaloo ndlela, ukuba inani lamazinyo e-rotor kunye nenani leebhithi ezibalekayo liqinisekile, isantya esifunwayo sinokufumaneka ngokulawula i-pulse frequency. Ekubeni i-motor stepper iqalwe ngoncedo lwe-torque yayo ye-synchronous, i-frequency yokuqala ayikho phezulu ukuze ingalahlekelwa yinyathelo. Ngokukodwa njengoko amandla enyuka, i-diameter ye-rotor iyanda, i-inertia iyanda, kwaye i-frequency yokuqala kunye ne-frequency ephezulu yokuqhuba ingahluka ngokuphindwe kalishumi.
Iimpawu zokuqala ze-frequency motor ye-stepper ukuze i-stepper motor iqale ingakwazi ukufikelela ngokuthe ngqo kwi-frequency yokusebenza, kodwa ibe nenkqubo yokuqalisa, oko kukuthi, ukusuka kwisantya esisezantsi ngokuthe ngcembe ukuya kwisantya sokusebenza. Yeka xa i-frequency yokusebenza ingenako ukuhla ngokukhawuleza ukuya kwi-zero, kodwa ukuba nesantya esiphezulu sokunciphisa isantya ukuya kwinkqubo ye-zero.
Ke ngoko, ukusebenza kwemotor ye-stepper ngokubanzi kufuneka kudlule isantya, isantya esifanayo, ukuthoba izigaba ezithathu, ukukhawulezisa kunye nenkqubo yokwehlisa isantya ngokufutshane, ixesha lesantya esingaguqukiyo kangangoko kunokwenzeka. Ngokukodwa kumsebenzi ofuna impendulo ekhawulezayo, ixesha elifunekayo ukubaleka ukusuka kwindawo yokuqala ukuya ekupheleni lilona lifutshane, elimele lifune inkqubo emfutshane yokukhawuleza kunye nokunciphisa, kunye nesantya esiphezulu kwisantya esiphezulu.
Ukukhawuleza kunye nokunciphisa i-algorithm yenye yezobuchwepheshe obuphambili kulawulo lwentshukumo, kunye nenye yezinto eziphambili zokufikelela kwisantya esiphezulu kunye nokusebenza okuphezulu. Kulawulo lwamashishini, kwelinye icala, inkqubo yokucubungula iyadingeka ukuba ihambe kakuhle kwaye izinzile, kunye nefuthe elincinci lokuguquguquka; kwelinye icala, kufuna ixesha lokuphendula ngokukhawuleza kunye nokusabela ngokukhawuleza. Kwisiseko sokuqinisekisa ukuchaneka kokulawula ukuphucula ukusebenza kakuhle, ukufezekisa ukunyakaza okugudileyo kunye nokuzinza komatshini, ukuqhutyelwa kwamashishini kwangoku kukusombulula ingxaki ephambili. I-acceleration kunye ne-deceleration algorithms esetyenziswa ngokuqhelekileyo kwiinkqubo zokulawula intshukumo yangoku ziquka: i-trapezoidal curve acceleration and deceleration, i-exponential curve and deceleration, i-S-shaped curve acceleration and deceleration, parabolic curve acceleration and deceleration, njl.
Isantya seTrapezoidal curve kunye nokuncipha
Inkcazo: Ukukhawuleza / ukuhla ngendlela yomgca (ukukhawuleza / ukuhla ukusuka kwisantya sokuqala ukuya kwisantya esijoliswe kuyo) kunye nomlinganiselo othile
Ifomula yokubala: v(t)=Vo+e
Izinto eziluncedo kunye nokungonakali: Ijika leTrapezoidal libonakaliswa nge-algorithm elula, ixesha elincinci lokutya, ukuphendula ngokukhawuleza, ukusebenza kakuhle kunye nokuphunyezwa ngokulula. Nangona kunjalo, izigaba zokukhawulezisa kunye nokunciphisa iyunifomu azihambelani nomthetho wokutshintsha isantya se-stepper, kwaye indawo yokutshintsha phakathi kwesantya esiguqukayo kunye nesantya esifanayo ayinakuba lula. Ngoko ke, le algorithm isetyenziswa ikakhulu kwizicelo apho iimfuno zokukhawulezisa kunye nenkqubo yokunciphisa isantya aziphezulu.
Ukukhawulezisa igophe kunye nokuncipha
Ingcaciso: Kuthetha ukukhawuleziswa kunye nokunciphisa isantya ngokusebenza kwe-exponential.
Ukukhawulezisa kunye nokunciphisa ulawulo lokuvavanya isalathisi:
1, Umkhondo womatshini kunye nempazamo yendawo kufuneka ibencinci kangangoko
2, Inkqubo yentshukumo yomatshini igudile, ijitter incinci, kwaye impendulo ikhawuleza
I-3, ukukhawulezisa kunye nokunciphisa i-algorithm kufuneka ibe lula kangangoko, kube lula ukuyiphumeza, kwaye inokuhlangabezana neemfuno zolawulo lwexesha lokwenyani.
