Ama-stepper motors ancipha kanjani?

I-Stepper motor njenge-drive motor evame ukusetshenziswa, esetshenziswa kabanzi, evame ukusetshenziswa nemishini ye-deceleration ukuze kuzuzwe umphumela omuhle wokudlulisela; kanye nemishini ye-stepper motor evame ukusetshenziswa nezindlela zokwehlisa amandla, njengebhokisi legiya lokunciphisa, isishumeki, isilawuli, isignali ye-pulse, njll.

 

Ukunciphisa isignali ye-Pulse:isivinini sokujikeleza kwe-stepper motor, sisekelwe ekushintsheni kwesignali ye-pulse yokufaka ukushintsha. Ngokombono, nikeza umshayeli ukushaya kwenhliziyo, i-stepper motor izungeza i-engeli yesinyathelo (ukuhlukaniswa kwe-engeli yesinyathelo sokuhlukanisa). Ngokwenza, uma isignali ye-pulse ishintsha ngokushesha kakhulu, i-stepper motor ngenxa yomphumela wangaphakathi wokudambisa amandla kagesi angemuva, impendulo kazibuthe phakathi kwe-rotor ne-stator ngeke ilandele ukuguqulwa kwesignali kagesi, kuzoholela ekuvimbeni nasekulahlekeni kwezinyathelo.

 

Ukwehliswa kwe-gearbox yokunciphisa:I-stepper motor ifakwe i-gearbox yokunciphisa esetshenziswa ndawonye, ​​i-stepper motor ephuma ngesivinini esikhulu, isivinini esiphansi se-torque, exhunywe ku-gearbox yokunciphisa, i-gearbox yokunciphisa igiya langaphakathi le-meshing transmission elakhiwe ngenani lokunciphisa, isivinini esikhulu se-stepper motor sizoncishiswa, futhi sithuthukise i-torque yokudlulisela ukuze kufinyelele umphumela ofanele wokudlulisela; umphumela wokunciphisa uncike esilinganisweni sokunciphisa ibhokisi legiya, sikhulu isilinganiso sokunciphisa, sibe sincane isivinini sokuphumayo, ngokuphambene nalokho. Futhi ngokuphambene.

 

Isivinini sokulawula ijika:i-exponential curve, ohlelweni lwesofthiwe, izilinganiso zesikhathi ezibalwe kuqala ezigcinwe kumemori yekhompyutha, zikhomba okukhethiwe lapho kusebenza. Imvamisa, ukuqedwa kokusheshisa kwe-stepper motor kanye nesikhathi sokunciphisa ama-300ms noma ngaphezulu. Uma usebenzisa ukusheshisa okufushane kakhulu kanye nesikhathi sokunciphisa, kuningi lama-motor stepper, kuzoba nzima ukufeza ukujikeleza ngesivinini esikhulu sama-motor stepper.

 

Ukunciphisa isilawuli sekhodi:Ukulawulwa kwe-PID njengendlela yokulawula elula nesebenzayo, ku-stepper motor drive ithole ukusetshenziswa okubanzi. Isekelwe enanini elinikeziwe elingu- r ( t ) kanye nenani langempela lokuphumayo c ( t ) ukuze kwakheke ukuchezuka kokulawula u- e ( t ) , ukuchezuka kokulinganiselwe , okubalulekile kanye nokuhluka ngenhlanganisela yomugqa wenani lokulawula , isilawuli sento yokulawula . Iphepha lisebenzisa inzwa yokuma edidiyelwe emotweni ye-hybrid stepper motor enezigaba ezimbili futhi iklama isilawuli sesivinini se-PI esilungiseka ngokuzenzakalelayo ngokusekelwe kumtshina wendawo kanye nokulawula kwe-vector, okunikeza izici zesikhashana ezanelisayo ngaphansi kwezimo zokusebenza eziguquguqukayo. Ngokusekelwe kumodeli yezibalo ye-stepper motor, uhlelo lokulawula lwe-PID lwe-stepper motor lwakhiwe futhi i-algorithm yokulawula ye-PID isetshenziselwa ukuthola inani lokulawula ukulawula ukunyakaza kwemoto endaweni ecacisiwe. Okokugcina, kuqinisekiswa ngokulinganisa ukuthi isilawuli sinezici ezinhle zokuphendula eziguqukayo. Isilawuli se-PID sinezinzuzo zesakhiwo esilula, ukuqina okuphezulu nokuthembeka okuphezulu, kodwa asikwazi ukubhekana ngokuphumelelayo nolwazi olungaqinisekile ohlelweni.

 

I-stepper motor ingafaniswa neyiphi i-reducer? Ephaketheni lokukhetha le-stepper motor kanye ne-gearbox udinga ukunaka lezo zici, futhi hlobo luni lwebhokisi lamagiya elingakhethwa ukuze lisetshenziswe ndawonye?

 

1. Isizathu se-stepper motor ene-reducer

 

I-stepper motor ishintsha imvamisa yesigaba samanje se-stator, njengokushintsha i-pulse yokufaka yesekethe ye-stepper motor drive, ukuze ibe ukunyakaza kwejubane eliphansi. Injini ye-stepper enesivinini esiphansi ekulindeni umyalo wokunyathela, i-rotor imile, ekunyathelweni kwejubane eliphansi, ukuguquguquka kwesivinini kuzoba kukhulu kakhulu, ngalesi sikhathi, njengokushintshela ekusebenzeni kwesivinini esikhulu, kungaxazulula inkinga yokuguquguquka kwesivinini, kodwa i-torque izobe inganele. Okusho ukuthi, ijubane eliphansi lizoshintshashintsha, futhi isivinini esikhulu sizoba yi-torque enganele, isidingo sokusebenzisa isinciphisi.

 

2. Stepper motor ngokuvamile nge reducer yini

 

I-Reducer iwuhlobo lwe-gear drive, i-worm drive, i-gear - worm drive, evalwe ku-casing eqinile, ivame ukusetshenziswa njengesinciphisi phakathi kwe-prime mover kanye nomshini wokusebenza, phakathi kwe-prime mover kanye nomshini wokusebenza noma i-actuator ukufanisa isivinini nokudluliswa kwe-torque; i-reducer inohlu olubanzi, ngokusho kohlobo lokudlulisa lungahlukaniswa lube i-gear reducer, i-worm gear reducer kanye ne-planetary gear reducer. Ngokwenani lezigaba zokudlulisela zingahlukaniswa zibe yi-single-stage kanye ne-multi-stage reducer; ngokuya ngokuma kwegiya ingahlukaniswa ibe yi-cylindrical gear reducer, i-bevel gear reducer kanye ne-bevel-cylindrical gear reducer; ngokuya ngefomu lohlelo lokudlulisela lingahlukaniswa libe i-reducer evuliwe, i-shunt reducer kanye ne-coaxial reducer. I-Stepper motor assembly reducer iyisinciphisi seplanethi, i-worm gear reducer, i-parallel gear reducer, i-filament gear reducer.

 

 

Kuthiwani ngokunemba kwe-stepper motor planetary reducer?

 

 

Ukunemba kokunciphisa kubizwa nangokuthi imvume yokubuyisela. Lapho isiphetho sokukhiphayo silungisiwe futhi isiphetho sokufakwayo sizungeziswa ngokwewashi nangokuphikisana newashi ukuze kukhiqizwe i-torque elinganiselwe + -2% ekugcineni kokuphumayo, kuba khona ukususwa kwe-angular encane ekugcineni kokufaka kwesinciphisi, futhi lokhu kususwa kwe-angular kuyimvume yokubuyisela. Iyunithi "imizuzu eyi-arc", okungukuthi ingxenye eyodwa yamashumi ayisithupha yedigri. Amanani ajwayelekile okubuyisela abhekisela ohlangothini oluphumayo lwebhokisi lika-gearbox. I-Stepper motor planetary reducer inokuqina okuphezulu, ukunemba okuphezulu (isiteji esisodwa singafinyelelwa kumzuzu ongu-1), ukusebenza kahle kokudlulisela okuphezulu (isiteji esisodwa ku-97% -98%), isilinganiso se-torque / ivolumu ephezulu, ukunganakeki, njll.

 

Ukunemba kokuhanjiswa kwe-stepper motor akushintsheki, i-stepper motor egijima i-angle inqunywa ngokuphelele ubude besinyathelo kanye nenani lama-pulses, futhi inani lama-pulses lingaba ukubala okuphelele, ubuningi bedijithali akuwona umqondo wokunemba, isinyathelo esisodwa isinyathelo esisodwa, izinyathelo ezimbili ziyizinyathelo ezimbili. Ukunemba kwamanje okungathuthukiswa wukunemba kwe-gear return clearance ku-gearbox weplanethi.
