Stepper motakushanda musimboti
Kazhinji, rotor yemota igineti yekusingaperi. Kana ikozvino inoyerera kuburikidza ne stator winding, stator winding inobudisa vector magnetic field. Iyi magnetic field inotyaira rotor kuti itenderere nekona kuitira kuti kutungamira kwemagineti maviri e rotor ienderane neiyo yemunda we stator. Apo vector magnetic field ye stator inotenderera nekona.
Stepper motaimhando yemota induction mota, misimboti yayo yekushanda ndeye kushandiswa kwemagetsi edunhu, iyo yakananga ikozvino mune yekugovera-nguva magetsi, multiphase timing control ikozvino, neiyi yazvino ye stepper mota magetsi, stepper mota inogona kushanda nemazvo, mutyairi ndeye stepper motor nguva-kugovera magetsi, multiphase timing controller.
Imwe neimwe inopinza pulse yemagetsi, mota inotenderedza kona kumberi nhanho imwe. Yayo inobuda angular displacement inoenderana nehuwandu hwemapulses ekuisa, kumhanya kunoenzanirana neiyo pulse frequency. Shandura kurongeka kwekuita mhepo simba, mota inodzokera kumashure. Saka iwe unogona kudzora huwandu hwemapulses, frequency uye kurongeka kwekusimbisa chikamu chimwe nechimwe chemotor winding kudzora kutenderera kweiyo stepper mota.
Iko kurongeka kweiyo general stepper mota ndeye 3-5% yeinotsika kona, uye haina kuunganidza.
Iyo torque yeanotsika mota inodzikira sezvo kumhanya kunowedzera. Sezvo iyo stepper mota inotenderera, iyo inductance yechikamu chimwe nechimwe chemotor winding inoumba reverse magetsi anogona; iyo yakakwirira frequency, iyo yakakura reverse magetsi anogona. Pasi pechiito chayo, mota ine frequency (kana kumhanya) inowedzera uye chikamu chazvino chinodzikira, izvo zvinotungamira mukuderera kwe torque.
Stepper mota inogona kushanda zvakajairika nekumhanya kwakaderera, asi kana yakakwira kupfuura imwe kumhanya haitangi, uye ichiperekedzwa nekuridza muridzo.
Stepper mota ine tekinoroji parameter: hapana-mutoro wekutanga frequency, ndiko kuti, iyo inotsika mota mune isina-mutoro pulse frequency inogona kutangwa zvakajairwa, kana iyo pulse frequency yakakwira kupfuura kukosha, mota haigone kutanga zvakajairika, inogona kuitika kunze kwenhanho kana kuvharira.
Muchiitiko chemutoro, nguva yekutanga inofanira kunge yakaderera. Kana iyo mota ichisvika pakumhanya kukuru kutenderera, iyo pulse frequency inofanirwa kunge iine acceleration process, kureva, iyo yekutanga frequency yakadzikira, uye yobva yasimuka kune yaidiwa yakakwirira frequency (motor kumhanya kubva yakaderera kumhanya kusvika kumusoro) pane imwe nguva yekumhanyisa.

Iko kumhanya kwemota inotsika kunoenderana ne pulse frequency, nhamba yemazino e rotor uye nhamba yekurova. Kumhanya kwayo kweangular kunoenzanirana neiyo pulse frequency uye inowiriraniswa nenguva pamwe nekupuruzira. Saka, kana nhamba yemazino e rotor uye nhamba yekumhanya bhiti ndeyechokwadi, kukurumidza kunodiwa kunogona kuwanikwa nekudzora pulse frequency. Sezvo iyo stepper mota inotangwa nerubatsiro rweiyo synchronous torque, iyo yekutanga frequency haina kukwirira kuitira kuti usarasikirwe nhanho. Kunyanya sezvo simba rinowedzera, iyo rotor dhayamita inowedzera, inertia inowedzera, uye iyo yekutanga frequency uye yakanyanya kumhanya frequency inogona kusiyana nekanopfuura kagumi.
Iyo yekutanga frequency maitiro eiyo stepper mota kuitira kuti iyo stepper mota itange haigone kusvika yakananga frequency yekushanda, asi kuve nekutanga-up maitiro, ndiko kuti, kubva pakaderera kumhanya zvishoma nezvishoma kusvika kune yekushanda kumhanya. Misa kana iyo frequency yekushanda isingagone kudonha nekukurumidza kusvika zero, asi kuve neiyo yepamusoro-yekumhanya zvishoma nezvishoma yekudzikisa kusvika ku zero process.
Naizvozvo, kushanda kweiyo stepper mota kazhinji kunofanirwa kupfuura nekumhanyisa, kumhanya kweyunifomu, kudzikisa matanho matatu, kukwidziridza uye kudzikamisa maitiro ipfupi sezvinobvira, inogara ichimhanya nguva yakareba sezvinobvira. Kunyanya mubasa rinoda kukurumidza kupindura, nguva inodiwa kuti umhanye kubva pakutanga kusvika kumagumo ndiyo ipfupi, iyo inofanirwa kupfupisa nzira yekumhanyisa uye kuderedza, uye yakanyanya kukurumidza kumhanya inogara ichimhanya.
Kukwidziridza uye kudzikisira algorithm ndeimwe yeakakosha matekinoroji mukutonga kwekufamba, uye chimwe chezvinhu zvakakosha kuti uwane kukurumidza kukurumidza uye kugona kwakanyanya. Mukutonga kwemaindasitiri, kune rumwe rutivi, maitiro ekugadzirisa anodiwa kuti ave akatsetseka uye akadzikama, ane diki diki inoshanduka; kune rumwe rutivi, zvinoda kukurumidza kupindura nguva uye kukurumidza kuita. Mumamiriro ezvinhu ekuona kudzora kurongeka kwekuvandudza mashandiro ekugadzirisa, kuti uwane yakatsetseka uye yakagadzikana yemuchina kufamba, iko ikozvino maindasitiri kugadzirisa kwave kugadzirisa dambudziko rakakosha. Iko kukwidziridza uye kudzikisira maalgorithms anowanzo shandiswa mune azvino mafambiro ekudzora masisitimu anonyanya kusanganisira: trapezoidal curve kukwirisa uye kudzikisira, exponential curve kukwirisa uye kudzikisira, S-yakaita curve kukwirisa uye kudzikisira, parabolic curve kukurumidza uye kudzikisira, nezvimwe.
Trapezoidal curve kukwidziridza uye kudzikisira
Tsanangudzo: Kumhanyisa/kudzikisira nenzira yemutsara (kumhanyisa/kudzikisira kubva pakumhanya kwekutanga kuenda kumhanyiro yekumhanyisa) neimwe chiyero.
Kuverengera formula: v(t)=Vo+at
Zvakanakira uye zvisingabatsiri: Trapezoidal curve inoratidzwa nealgorithm iri nyore, nguva shoma inopedza, mhinduro inokurumidza, hukuru hwepamusoro uye nyore kuita. Nekudaro, iyo yunifomu yekumhanyisa uye nhanho yekudzikisa haienderane neinotsika mota yekumhanyisa shanduko mutemo, uye nzvimbo yekuchinja pakati pekumhanyisa kumhanya uye yunifomu kumhanya haigone kuve yakatsetseka. Naizvozvo, iyi algorithm inonyanya kushandiswa mumashandisirwo apo izvo zvinodikanwa zvekumhanyisa uye deceleration maitiro hazvina kukwirira.
Exponential curve kukwidziridza uye kudzikisira
Tsanangudzo: Zvinoreva kukurumidza uye kuderedzwa neexponential function.
Kukwidziridza uye kudzikisira kudzora evaluation index:
1, Muchina trajectory uye chinzvimbo chikanganiso chinofanira kunge chiri chidiki sezvinobvira
2, Muchina wekufamba maitiro akatsetseka, jitter idiki, uye mhinduro inokurumidza
3, kukwidziridza uye kudzikisira algorithm inofanira kunge iri nyore sezvinobvira, nyore kuita, uye inogona kusangana neiyo chaiyo-nguva yekudzora zvinodiwa.
Kana iwe uchida kutaurirana uye kushanda nesu, ndapota inzwa wakasununguka kutibata nesu.
