Umgaqo wokuvelisa ubushushuimoto ye-stepper.
1, ngokuqhelekileyo ubona zonke iintlobo zeenjini, i-iron core kunye ne-winding coil yangaphakathi.Ukujika-jika kunokumelana, amandla aya kuvelisa ilahleko, ubungakanani bokulahleka bulingana nesikwere sokumelana kunye nomsinga, odla ngokubizwa ngokuba yilahleko yobhedu, ukuba umsinga awungowomgangatho we-DC okanye i-sine wave, uya kuvelisa ilahleko ye-harmonic; i-core ine-hysteresis eddy current effect, kwintsimi yemagnethi etshintshanayo nayo iya kuvelisa ilahleko, ubungakanani bayo kunye nezinto zayo, umsinga, i-frequency, i-voltage, ebizwa ngokuba yilahleko yesinyithi. Ilahleko yobhedu kunye nelahleko yesinyithi ziya kubonakala ngendlela yobushushu, ngaloo ndlela zichaphazela ukusebenza kakuhle kwemoto. Iimoto ze-Stepper ngokubanzi zilandela ukuchaneka kokubeka kunye nemveliso ye-torque, ukusebenza kakuhle kuphantsi, umsinga ngokubanzi mkhulu, kwaye izinto eziphezulu ze-harmonic, i-frequency ye-current alternation nayo iyahluka ngokwesantya, kwaye ngaloo ndlela iimoto ze-stepper ngokubanzi zinobushushu, kwaye imeko imbi ngakumbi kunemoto ye-AC ngokubanzi.
2, uluhlu olufanelekileyo lweimoto ye-stepperubushushu.
Ubushushu bemoto obuvumelekileyo ukuya kuthi ga kwinqanaba elingakanani, ikakhulu buxhomekeke kwinqanaba lobushushu bangaphakathi bemoto. Ukusebenza kobushushu bangaphakathi kumaqondo obushushu aphezulu (ii-degrees ezili-130 nangaphezulu) ngaphambi kokuba kutshatyalaliswe. Ngoko ke, logama nje ingaphakathi lingadluli kwii-degrees ezili-130, imoto ayiyi kulahlekelwa yiringi, kwaye ubushushu bomphezulu buya kuba ngaphantsi kwee-degrees ezingama-90 ngeli xesha.
Ngoko ke, ubushushu bomphezulu we-stepper motor buqhelekile. Indlela elula yokulinganisa ubushushu iluncedo, unokufumanisa ngokucacileyo: ngesandla ungachukumisa imizuzwana engaphezu kwe-1-2, kungabi ngaphezu kwe-60 degrees; ngesandla ungachukumisa kuphela, malunga ne-70-80 degrees; amaconsi ambalwa amanzi akhawuleza anyibilike, angaphezulu kwe-90 degrees.
3, imoto ye-stepperukufudumeza ngotshintsho lwesantya.
Xa kusetyenziswa iteknoloji yokuqhuba umbane oqhubekayo, ii-stepper motors kwisantya esingaguqukiyo nesiphantsi, umbane uya kuhlala unjalo ukugcina umbane oqhubekayo. Xa isantya siphezulu ukuya kwinqanaba elithile, amandla angaphakathi e-counter potential emoto ayaphakama, umbane uya kwehla kancinci kancinci, kwaye umbane uya kwehla.
Ngoko ke, imeko yokufudumeza ngenxa yokulahleka kobhedu iya kuxhomekeka kwisantya. Isantya esingaguqukiyo nesiphantsi sidla ngokuvelisa ubushushu obuphezulu, ngelixa isantya esiphezulu sivelisa ubushushu obuphantsi. Kodwa utshintsho lokulahleka kwesinyithi (nangona luncinci) alufani, kwaye i-motor njengobushushu iyonke yimbumba yezi zimbini, ngoko ke oku kungasentla yimeko eqhelekileyo kuphela.
4, impembelelo yobushushu.
Nangona ubushushu bemoto ngokubanzi bungachaphazeli ubomi bemoto, uninzi lwabathengi akufuneki banikele ingqalelo kubo. Kodwa ngokwenene kuya kuzisa impembelelo embi. Ezifana nee-coefficients ezahlukeneyo zokwandiswa kobushushu kwiindawo zangaphakathi zemoto zikhokelela kutshintsho kuxinzelelo lwesakhiwo kunye notshintsho oluncinci kumsantsa womoya wangaphakathi, ziya kuchaphazela impendulo eguqukayo yemoto, isantya esiphezulu siya kuba lula ukuphulukana nenyathelo. Omnye umzekelo kukuba ezinye izihlandlo azivumeli ubushushu obugqithisileyo bemoto, njengezixhobo zonyango kunye nezixhobo zovavanyo oluchanekileyo, njl. Ke ngoko, ubushushu bemoto kufuneka bube yimfuneko ukulawula.
5, indlela yokunciphisa ubushushu bemoto.
Ukunciphisa ukuveliswa kobushushu, kukunciphisa ukulahleka kobhedu kunye nokulahleka kwesinyithi. Ukunciphisa ukulahleka kobhedu kwiindlela ezimbini, ukunciphisa uxhathiso kunye nombane, nto leyo efuna ukukhethwa kokumelana okuncinci kunye nombane olinganisiweyo wemoto kangangoko kunokwenzeka, i-motor yezigaba ezimbini, i-motor ingasetyenziswa kuthotho ngaphandle kwe-motor ehambelanayo. Kodwa oku kudla ngokuchasana neemfuno ze-torque kunye nesantya esiphezulu. Kwi-motor ekhethiweyo, umsebenzi wolawulo lwe-half-current oluzenzekelayo lwe-drive kunye nomsebenzi we-offline kufuneka usetyenziswe ngokupheleleyo, owokuqala unciphisa umbane ngokuzenzekelayo xa i-motor iphumle, kwaye owokugqibela unqumla nje umbane.
Ukongeza, i-division drive, kuba i-current waveform ikufutshane ne-sinusoidal, i-harmonics encinci, ukufudumeza kwe-motor kuya kuba ncinci. Zimbalwa iindlela zokunciphisa ukulahleka kwentsimbi, kwaye inqanaba le-voltage linxulumene nalo. Nangona i-motor eqhutywa yi-voltage ephezulu iya kuzisa ukonyuka kweempawu zesantya esiphezulu, ikwazisa ukonyuka kokuveliswa kobushushu. Ngoko ke kufuneka sikhethe inqanaba le-voltage ye-drive elifanelekileyo, sithathela ingqalelo isantya esiphezulu, ukuthamba kunye nobushushu, ingxolo kunye nezinye izalathisi.
Iindlela zokulawula iinkqubo zokukhawulezisa kunye nokuthomalalisa isantya seemoto ze-stepper.
Ngenxa yokusetyenziswa ngokubanzi kwee-stepper motors, uphando lolawulo lwee-stepper motor luyanda, ekuqaleni okanye ekukhawuleziseni ukuba i-stepper pulse itshintsha ngokukhawuleza kakhulu, i-rotor ngenxa ye-inertia kwaye ingalandeli utshintsho lwesignali yombane, okubangela ukuba i-blockage okanye i-loss step inyuke xa imisa okanye i-deceleration ngesizathu esifanayo inokubangela i-overstep. Ukuze kuthintelwe i-blockage, i-loss of step and overshoot, phucula i-frequency yokusebenza, i-stepper motor iphakamise ulawulo lwesantya.
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 ingenakuncipha ngoko nangoko iye kwi-zero, kodwa ibe ne-high-speed slow speed reduction ukuya kwi-zero process.
I-torque yokukhupha ye-stepper motor iyancipha ngokunyuka kwe-pulse frequency, okukhona i-frequency yokuqala iphezulu, i-torque yokuqala incinci, kokukhona amandla okuqhuba umthwalo ebuthathaka, isiqalo siya kubangela ukulahleka kwesinyathelo, kwaye ekumisweni kuya kwenzeka xa i-overshoot igqithisile. Ukuze i-stepper motor ifikelele ngokukhawuleza kwisantya esifunekayo kwaye ingalahlekelwa yinyathelo okanye i-overshoot, isitshixo kukwenza inkqubo yokukhawulezisa, i-torque yokukhawulezisa efunekayo ukuze isebenzise ngokupheleleyo i-torque enikezelwa yi-stepper motor kwi-frequency nganye yokusebenza, kwaye ingadluli le torque. Ke ngoko, ukusebenza kwe-stepper motor ngokubanzi kufuneka kudlule kwi-acceleration, isantya esifanayo, i-deceleration izigaba ezithathu, ixesha lenkqubo yokukhawulezisa kunye ne-deceleration lifutshane kangangoko kunokwenzeka, ixesha lesantya esiqhubekayo lide kangangoko kunokwenzeka. Ingakumbi emsebenzini ofuna impendulo ekhawulezileyo, ukusuka kwindawo yokuqala ukuya ekupheleni kwexesha lokusebenza elifunekayo ukuba libe lifutshane, ekufuneka lifune i-acceleration, inkqubo yokukhawulezisa yeyona imfutshane, ngelixa isantya esiphezulu kwisantya esingapheliyo.
Izazinzulu kunye neengcali zasekhaya nakwamanye amazwe zenze uphando oluninzi malunga netekhnoloji yokulawula isantya seemoto ze-stepper, kwaye zaseka iintlobo ngeentlobo zeemodeli zezibalo zokulawula ukukhawulezisa kunye nokuthomalalisa, ezifana nemodeli ye-exponential, imodeli ethe tye, njl.njl., kwaye ngokusekelwe kolu yilo kunye nophuhliso lweesekethe ezahlukeneyo zolawulo ukuphucula iimpawu zokuhamba kweemoto ze-stepper, ukukhuthaza uluhlu lokusetyenziswa kweemoto ze-stepper. Ukukhawulezisa kunye nokuthomalalisa kuthathela ingqalelo iimpawu ze-moment-frequency zemoto ze-stepper, zombini ukuqinisekisa ukuba imoto ye-stepper ishukuma ngaphandle kokulahlekelwa yinyathelo, kodwa ikwanika ukudlala ngokupheleleyo kwiimpawu ze-motor, inciphisa ixesha lesantya sokuphakamisa, kodwa ngenxa yotshintsho kumthwalo wemoto, kunzima ukufezekisa ngelixa ukukhawulezisa kunye nokuthomalalisa kuthe qwa kuphela kuthathela ingqalelo imoto kuluhlu lomthamo womthwalo we-angular velocity kunye ne-pulse ngokulingana nolu lwalamano, kungekhona ngenxa yokuguquguquka kwi-voltage yonikezelo, indawo yomthwalo kunye neempawu zotshintsho, le ndlela yokukhawulezisa isantya ihlala ihleli, ingxaki kukuba ayicingi ngokupheleleyo i-torque yokukhupha i-stepper motor. Ngeempawu zokutshintsha kwesantya, imoto ye-stepper kwisantya esiphezulu iya kwenzeka ngaphandle kwenyathelo.
Le yintshayelelo kumgaqo wokufudumeza kunye netekhnoloji yokulawula inkqubo yokukhawulezisa/yokunciphisa isantya se-stepper motors.
