Chivharo chakavharwamota dzesteppervakachinja chiyero chekushanda-ne-mutengo mumashandisirwo mazhinji ekudzora kufamba. Kubudirira kweVIC closed-loop progressive motors kwakavhurawo mukana wekutsiva maservo motors anodhura neasina mutengo wakaderera.mota dzestepper.Mukuwedzera kuri kuita mashandisirwo emhando yepamusoro ekushandisa otomatiki mumaindasitiri, kufambira mberi kwetekinoroji kuri kuchinja chiyero chekushanda-ne-mutengo pakati pemamota estepper nemamota eservo.
Mota dzeStepper dzichienzaniswa nemota dzeservo
Zvichienderana nepfungwa dzemazuva ose, masisitimu ekudzora servo anoshanda zviri nani mukushandiswa uko kumhanya kunodarika 800 RPM uye mhinduro yakasimba inodiwa. Mota dzestepper dzakanyanya kukodzera kushandiswa dzine kumhanya kwakaderera, kumhanya kwakaderera kusvika pakati nepakati uye torque yakasimba.
Saka chii chiri hwaro hweuchenjeri uhwu hwechinyakare nezvema stepper motors nema servo motors? Ngationgororei zvakadzama pazasi.
1. Zviri nyore uye mutengo
Mamota eStepper haana kudhura zvakanyanya kupfuura mamota eservo chete, asi ari nyorewo kuagadzira nekuagadzirisa. Mamota eStepper akagadzikana kana akamira uye anomira panzvimbo yawo (kunyangwe aine mutoro unochinja). Zvisinei, kana paine mashandiro akakwirira anodiwa kune mamwe mashandisirwo, mamota eservo anodhura uye akaomarara anofanira kushandiswa.
2. Chimiro
Mota dzematanhotenderera zvishoma nezvishoma, uchishandisa magineti coils kudhonza magineti zvishoma nezvishoma kubva panzvimbo imwe kuenda kune inotevera. Kuti mota ifambise nzvimbo zana kune chero divi, dunhu rinoda kuti injini iite mabasa zana ekutsika. Mamota estepper anoshandisa mapulse kuti aite mafambiro ekuwedzera, zvichibvumira nzvimbo chaiyo pasina kushandisa ma sensors emhinduro.
Nzira yekufambisa yemota yeservo yakasiyana. Inobatanidza sensor yenzvimbo - kureva encoder - kune rotor yemagineti uye inoramba ichiona nzvimbo chaiyo yemota. Servo inotarisa musiyano uripo pakati penzvimbo chaiyo yemota nenzvimbo yakarairwa uye inogadzirisa magetsi zvinoenderana. Iyi sisitimu yakavharika inoita kuti mota irambe iri mumamiriro akakodzera ekufamba.
3. Kumhanya uye torque
Musiyano mukushanda pakati pemamota estepper neservo unobva mukugadzirisa kwavo kwakasiyana kwemota.Mota dzematanhodzine nhamba yakakura kwazvo yemapango kupfuura maservomotor, saka kutenderera kwakazara kwemota yestepper kunoda kuchinjana kwakawanda kwemagetsi, zvichikonzera kudzikira kwetorque nekukurumidza pakumhanya kuri kuwedzera. Pamusoro pezvo, kana torque yakanyanya ikasvika, mota yestepper inogona kurasikirwa nebasa rayo rekubatanidza kumhanya. Nekuda kwezvikonzero izvi, maservo motors ndiwo mhinduro inofarirwa muzvishandiso zvakawanda zvinomhanya zvakanyanya. Kusiyana neizvi, nhamba yakakura yemapango emota yestepper inobatsira pakumhanya kwakaderera, kana mota yestepper iine mukana wetorque kupfuura mota yeservo yehukuru hwakaenzana.
Sezvo kumhanya kuchiwedzera, torque yemota yestepper inoderera
4. Kuisa Nzvimbo
Pane musiyano wakakosha pakati pemamota estepper nemamota eservo mukushandiswa uko nzvimbo chaiyo yemuchina inofanira kuzivikanwa nguva dzese. Mukushandiswa kwemafambiro e open-loop anodzorwa nemamota estepper, sisitimu yekudzora inofungidzira kuti mota inogara iri mumamiriro chaiwo ekufamba. Zvisinei, mushure mekunge dambudziko raitika, senge mota yakamiswa nekuda kwechikamu chakanamira, controller haigone kuziva nzvimbo chaiyo yemuchina, izvo zvinogona kukonzera kurasikirwa nenzvimbo. Sisitimu ye closed-loop yemota yeservo pachayo ine mukana: kana ikavharirwa nechinhu, ichaiona nekukasika. Muchina uchamira kushanda uye hauzombofi wakabuda panzvimbo.
5. Kushandiswa kwekupisa nesimba
Mamota ekufambisa anotenderera anovhura-loop anoshandisa magetsi asina kugadzika uye anopa kupisa kwakawanda. Kudzora kwemagetsi anotenderera kunopa magetsi anodiwa pakufamba kwemhepo chete saka nekudaro kudzivirira dambudziko rekupisa kwemota.
Pfupiso yekuenzanisa
Masisitimu ekudzora servo akakodzera zvakanyanya kushandiswa nekukurumidza kunosanganisira kuchinja mutoro, senge maoko erobhoti. Masisitimu ekudzora stepper, kune rumwe rutivi, akakodzera kushandiswa kunoda kukurumidza kushoma kusvika pakati nepakati uye torque yakakwirira, senge 3D printers, conveyors, sub axes nezvimwewo. Nekuti mota dzestepper dzakachipa, dzinogona kuderedza mutengo wemasisitimu eotomatiki kana dzichishandiswa. Masisitimu ekudzora kufamba anofanirwa kushandisa hunhu hwemota dzeservo anofanira kuratidza kuti mota idzi dzinodhura zvakanyanya dzakakosha huremu hwadzo hwegoridhe.
Mota dzestepper dzine control yakavharwa
Mota yestepper ine integrated electronic control yakaenzana nemota yeDC isina mabhurashi maviri uye inogona kuita position loop control, speed loop control, DQ control, nedzimwe algorithms. Single-turn absolute encoder inoshandiswa pakuchinja kwe closed-loop, nokudaro ichivimbisa torque yakakwana chero kumhanya kupi zvako.
Kushandiswa kwesimba shoma uye kuchengetedza kutonhora
Mamota eVIC stepper anoshandisa simba rakawanda. Kusiyana nemamota eopen-loop stepper, anogara achishanda nesimba rakazara uye achikonzera matambudziko ekupisa neruzha, simba remagetsi rinoshanduka zvichienderana nemamiriro chaiwo ekufamba, semuenzaniso panguva yekumhanyisa uye kudzikira kwesimba. Kufanana nemaservo, simba remagetsi rinodyiwa nemamota aya estepper chero nguva rinoenderana ne torque chaiyo inodiwa. Nekuti mota nebhodhi rekudzora remagetsi rakabatanidzwa zvinotonhorera, mamota eVIC stepper anogona kuwana torque dzakakwirira dzakafanana ne servo motors.
Kunyangwe pakumhanya kwakanyanya, mota dzeVIC stepper dzinoda magetsi mashoma
Zvichitungamirirwa nekufambira mberi kwetekinoroji ye closed-loop, mota dze stepper dzinokwanisa kupinda mukushanda kwepamusoro-soro, uye kumhanya kwakanyanya kwaimbove kwemota dze servo chete.
Mota dzestepper dzine tekinoroji yeclosed-loop
Ko kana mabhenefiti e servo technology yakavharwa-loop angashandiswa kuma stepper motors?
Tingakwanisa here kuita zvakafanana nemamota eservo uku tichiri kuona mabhenefiti emota dzestepper?
Nekubatanidza tekinoroji yekudzora yakavharirwa, mota yestepper yaizova chigadzirwa chakakwana chine mabhenefiti emota dzeservo nestepper pamutengo wakaderera. Nekuti mota dzestepper dzakavharirwa dzinopa kuvandudzwa kukuru mukushanda uye kushanda zvakanaka kwesimba, dzinogona kutsiva mota dzeservo dzinodhura zvakanyanya muhuwandu huri kuwedzera hwemashandisirwo epamusoro-soro.
Inotevera muenzaniso wemota yeVIC integrated stepper ine embedded closed-loop control kutsanangura mashandiro uye zvakanakira uye zvakaipa zvemota dzestepper dzine tekinoroji yeclosed-loop.
Zvinodiwa zvekushanda zvakanyatsoenderana
Kuti ive nechokwadi chekuti torque yakakwana yekukunda matambudziko uye kudzivirira matanho akarasika, mota dze open-loop stepper dzinowanzo fanirwa kuve nechokwadi chekuti torque yakakwira ne40% kupfuura kukosha kunodiwa nekushandisa. Motokari dze closed-loop dzese hadzina dambudziko iri. Kana mota dze stepper idzi dzikamira nekuda kwekuwanda, dzinoramba dzichibata mutoro pasina kurasikirwa ne torque. Dzicharamba dzichishanda mushure mekunge mamiriro ekuwanda abviswa. Torque yepamusoro inogona kuvimbiswa chero kumhanya kwakapihwa uye sensor yenzvimbo inovimbisa kuti hapana kurasikirwa kwematanho. Motokari dze closed-loop stepper dzinogona kutsanangurwa kuti dzienderane nezvinodiwa zve torque zvekushandisa kwakakodzera pasina kudiwa kwekuwedzera 40%.
Nemamota estepper anovhurika, zvakaoma kusangana nezvinodiwa zve torque yakakwira nekukurumidza nekuda kwenjodzi yekurasikirwa nematanho. Kana tichienzanisa nemamota estepper akajairwa, mamota estepper anovhara eVIC anogona kukurumidza nekukurumidza, ruzha rwakaderera uye ruzha rwakaderera. Anogona kushanda pabandwidths yakakwirira uye kuita basa rakanaka kwazvo.
Hapana kabhineti
Toda inobatanidza bhodhi rekudzora madhiraivha nemota, zvichideredza kuwanda kwewaya uye zvichiita kuti mhinduro yekushandisa ive nyore. NaToda, unogona kuvaka michina isina makabati.
Kubatanidza magetsi nemota dzestepper kunoderedza kuoma kwekushandisa
Nehunyanzvi hwe closed-loop, closed-loop stepper motors dzinopa vashandisi kururama kwakanaka uye kushanda zvakanaka, nekushanda kwe servo motor uye mutengo wakaderera we stepper motor. Stepper motors dzinodhura zvishoma nezvishoma dziri kupinda mumashandisirwo ayo dai pasina izvozvo aizotongwa ne servo motors dzinodhura zvakanyanya.
