Ma stepper motors anodzikiswa sei?

Stepper motorsma electromechanical madivayiri anoshandura zvakananga ma impulses emagetsi kuita ma mechanical motion. Nekudzora kutevedzana, kuwanda uye huwandu hwemagetsi emagetsi akaiswa kune mota coils, stepper motors inogona kudzorwa yekufambisa, kumhanya uye kona yekutenderera. Pasina rubatsiro rweyakavharwa-loop mhinduro yekudzora system ine chinzvimbo inonzwa, chaiyo chinzvimbo uye kukurumidza kutonga inogona kuwanikwa kuburikidza nekushandisa iri nyore, yakaderera-inodhura yakavhurika-loop control system inosanganisira stepper mota uye inoperekedza mutyairi.

Kutsika mota sechinhu chepamusoro, ndechimwe chezvinhu zvakakosha zve mechatronics, inoshandiswa zvakanyanya muakasiyana otomatiki ekudzora masisitimu. Nekuvandudzwa kweiyo microelectronics tekinoroji uye chaiyo yekugadzira tekinoroji, kudiwa kwema stepper motors kuri kuwedzera zuva nezuva, uye stepper motors uye giya rekufambisa dhizaini rakasanganiswa nemagiya mabhokisi, zvakare mune akawanda uye akawanda ekushandisa mamiriro ekuona, nhasi uye wese munhu kuti anzwisise rudzi urwu rwegiya bhokisi rekufambisa.

How to deceleratestepper motor?

Sechinowanzo shandiswa uye chinoshandiswa zvakanyanya dhiraivha mota, stepper mota inowanzo shandiswa pamwe chete nedeceleration michina kuti iwane yakanakira kutapurirana maitiro; uye iyo inowanzo shandiswa yekudzikisa midziyo uye nzira dze stepper mota dzakaita senge deceleration magiya mabhokisi, encoder, controller, pulse masaini uye zvichingodaro.

Pulse sign deceleration: stepper mota kumhanya, yakavakirwa pane yekupinda pulse chiratidzo shanduko kuchinja. Nedzidziso, ipa mutyairi kupomba, iyostepper motorinotenderedza kona yenhanho (yakakamurwa kune yakakamurwa nhanho kona). Mukuita, kana iyo pulse chiratidzo ichichinja nekukurumidza, iyo stepper mota, nekuda kwekunyorovesa kwemukati reverse electromotive simba, iyo magineti inopindirana pakati perotor uye stator haizokwanisi kutevedzera shanduko yemagetsi chiratidzo, izvo zvinozotungamira kuvharira uye nhanho kurasikirwa.

Kudzikisira giya bhokisi kudzikisira: inotsika mota ine yekudzikisa giya bhokisi rinoshandiswa pamwechete, iyo inotsika mota inobuda yakakwira kumhanya, yakaderera torque kumhanya, yakabatana neiyo yekudzikisa giya bhokisi, giya bhokisi remukati rekutapudza magiya mesh kutapurirana akaumbwa nereshiyo yekudzikisa, iyo inotsika mota inobuda yekumhanyisa kudzikisira, uye kuwedzera torque yekufambisa, kuti iwane yakanakira kutapurirana maitiro; deceleration mhedzisiro inoenderana negiya bhokisi rekudzikisa reshiyo, iyo yakakura yekudzikisa reshiyo, iyo idiki yekumhanya yekubuda, uye zvinopesana. Mhedzisiro yekudzikisira inoenderana neiyo giya bhokisi rekudzikisira reshiyo, iyo yakakura iyo yekudzikisa reshiyo, iyo idiki yekumhanyisa kumhanya uye zvinopesana.

Curve exponential control kumhanya: exponential curve, mune software programming, yekutanga kuverenga yenguva yakagara yakachengetwa mundangariro yekombuta, basa rinonongedza kusarudzo. Kazhinji, iyo yekumhanyisa uye yekudzikisa nguva yekupedzisa stepper mota inodarika mazana matatu ms. Kana iwe ukashandisa yakawedzera kupfupika kumhanyisa uye deceleration nguva, kune iyo yakawanda yestepper motors, zvichave zvakaoma kuwana yakakwira-kumhanya kutenderera kweiyo stepper mota.

Encoder-inodzorwa kudzikisira: PID kutonga, senzira yakapusa uye inoshanda yekudzora nzira, yakashandiswa zvakanyanya mumatanho emota madhiraivha. Inobva pane yakapiwa kukosha r ( t ) uye iyo chaiyo yakabuda kukosha c ( t ) inoumba kudzora kutsauka e ( t ), kutsauka kwekuenzanisa, kubatanidzwa uye kusiyanisa kuburikidza nemutsara wekubatanidza kwehuwandu hwekutonga, chinhu chinodzorwa chekutonga. Iyo yakasanganiswa chinzvimbo sensor inoshandiswa mune maviri-chikamu hybrid stepper mota, uye auto-inogadziriswa PI yekumhanyisa controller inogadzirwa pahwaro hwenzvimbo detector uye vector control, iyo inogona kupa inogutsa yenguva pfupi hunhu pasi pemamiriro ekushanda akasiyana. Zvinoenderana neiyo masvomhu modhi yeinotsika mota, iyo PID yekudzora system yeinotsika mota yakagadzirwa, uye iyo PID control algorithm inoshandiswa kuwana huwandu hwekutonga, kuitira kudzora mota kuti iende kunzvimbo yakatarwa.

Chekupedzisira, kutonga kunosimbiswa nekuenzanisa kuve neakanaka dynamic mhinduro maitiro. Iko kushandiswa kwePID controller kune zvakanakira chimiro chakareruka, kusimba, kuvimbika uye zvichingodaro, asi haigone kubata nemazvo ruzivo rusina chokwadi muhurongwa.
