Mota yesteppermusimboti wekushanda
Kazhinji, rotor yemota imagneti inogara iripo. Kana magetsi achipfuura nemu stator winding, stator winding inogadzira vector magnetic field. Simba iri remagineti rinoita kuti rotor itenderere ne angle kuitira kuti divi re rotor remagineti maviri rienderane nere stator's field. Kana vector magnetic field ye stator ichitenderera ne angle.
Mota yestepperInjini ye induction, musimboti wayo wekushanda ndeyekushandisa electronic circuit, direct current mu time-sharing power supply, multiphase timing control current, neiyi current ye stepper motor power supply, stepper motor inogona kushanda nemazvo, driver ndeye stepper motor time-sharing power supply, multiphase timing controller.
Imwe neimwe inopinza pulse yemagetsi, mota inotenderera angle ichienda mberi nhanho imwe. Kufamba kwayo kwekona kunobuda kunoenderana nehuwandu hwemapulse anopinzwa, kumhanya kunoenderana nehuwandu hwemapulse. Chinja kurongeka kwesimba rekutenderera, mota ichadzokera shure. Saka unogona kudzora huwandu hwemapulse, mafrequency uye kurongeka kwesimba rechikamu chimwe nechimwe chekutenderera kwemota kuti utonge kutenderera kwemota yekukwira.
Kururama kwemota ye general stepper kuri 3-5% ye stepping angle, uye haiunganidzi.
Torque yemota yestepper ichaderera sezvo kumhanya kuchiwedzera. Sezvo mota yestepper ichitenderera, inductance yechikamu chimwe nechimwe chekutenderera kwemota ichagadzira reverse electric potential; kana frequency yakakwira, reverse electric potential yakakura. Pasi pekushanda kwayo, mota ine frequency (kana speed) inowedzera uye phase current inoderera, izvo zvinotungamira kudzikira kwetorque.
Injini yeStepper inogona kushanda zvakanaka nekumhanya kwakaderera, asi kana yakakwira kupfuura imwe kumhanya, haizotangi, uye inoperekedzwa nekurira kwemuridzo.
Mota yeStepper ine parameter yehunyanzvi: frequency yekutanga isina mutoro, kureva kuti, mota yestepper kana isina mutoro inogona kutanga zvakajairika, kana frequency yepulse yakakwira kupfuura kukosha, mota haigone kutanga zvakajairika, inogona kuitika kunze kwedanho kana kuvharika.
Kana paine mutoro, frequency yekutanga inofanira kunge yakaderera. Kana mota ichida kutenderera nekukurumidza, frequency yekurova kwemoyo inofanira kunge iine nzira yekumhanyisa, kureva kuti, frequency yekutanga yakaderera, uye yozokwira kusvika pafrequency yaunoda (speed yemota kubva pakumhanya kwakaderera kusvika pakumhanya kwakanyanya) pane imwe acceleration.
Sei uchiitamota dzestepperinofanira kudzorwa nekuderedza kumhanya
Kumhanya kwemota yestepper kunoenderana ne pulse frequency, huwandu hwemazino e rotor uye huwandu hwe beats. Kumhanya kwayo kwe angular kunoenderana ne pulse frequency uye kunowiriraniswa nenguva ne pulse. Saka, kana huwandu hwemazino e rotor nehuwandu hwe beats dziripo, kumhanya kwaunoda kunogona kuwanikwa nekudzora pulse frequency. Sezvo mota yestepper ichitangwa nerubatsiro rwe synchronous torque yayo, starting frequency haisi yakakwira kuitira kuti isarasike nhanho. Kunyanya sezvo simba richiwedzera, dhayamita ye rotor inowedzera, inertia inowedzera, uye starting frequency uye maximum running frequency zvinogona kusiyana kanosvika kagumi.
Maitiro ekutanga emota yestepper kuitira kuti mota yestepper irege kusvika zvakananga pakushanda, asi kuti ive nekutanga-up process, kureva kuti, kubva pakumhanya kwakaderera zvishoma nezvishoma kusvika pakumhanya kwekushanda. Mira kana frequency yekushanda isingakwanise kudonha pakarepo kusvika pazero, asi kuti ive nekumhanya kwakanyanya kuderedzwa zvishoma nezvishoma kusvika pazero process.
Saka, mashandiro emota yestepper anowanzo fanirwa kupfuura nemumatanho matatu ekukurumidzisa, kumhanya kwakafanana, kudzikamisa mafambiro, maitiro ekukurumidzisa uye kudzikamisa mafambiro mapfupi sezvinobvira, nguva yekumhanya nguva dzose yakareba sezvinobvira. Kunyanya mubasa rinoda mhinduro nekukurumidza, nguva inodiwa kuti imhanye kubva pakutanga kusvika kumagumo ndiyo pfupi, iyo inofanirwa kuda nzira pfupi yekukurumidzisa uye kudzikamisa mafambiro, uye kumhanya kwepamusoro pakumhanya nguva dzose.
Algorithm yekukurumidzira nekudzikamisa mafambiro ndeimwe yematekinoroji akakosha mukudzora kufamba, uye chimwe chezvinhu zvakakosha kuti uwane kumhanya kwakanyanya uye kushanda zvakanaka. Mukudzora kwemaindasitiri, kune rumwe rutivi, maitiro ekugadzirisa anofanirwa kunge akapfava uye akagadzikana, aine kushanduka kudiki; kune rumwe rutivi, zvinoda nguva yekupindura nekukurumidza uye kuita nekukurumidza. Mukufunga kwekuona kuti kutonga kwakarurama kuti uvandudze kushanda zvakanaka, kuti uwane kufamba kwakapfava uye kwakasimba kwemakanika, kugadzirisa kwemaindasitiri kwave kuri kugadzirisa dambudziko guru. Algorithms yekukurumidzira nekudzikamisa mafambiro anowanzo shandiswa mumasisitimu ekudzora kufamba kwazvino anosanganisira: trapezoidal curve acceleration and deceleration, exponential curve acceleration and deceleration, S-shaped curve acceleration and deceleration, parabolic curve acceleration and deceleration, nezvimwewo.
Kukurumidza uye kuderera kweTrapezoidal curve
Tsanangudzo: Kukurumidza/kudzikira kwesimba nenzira yakatsetseka (kukurumidzisa/kudzikira kubva pakumhanya kwekutanga kusvika pakumhanya kwakanangana) nechiyero chakati
Fomura yekuverenga: v(t)=Vo+at
Zvakanakira nezvayakaipira: Trapezoidal curve inoratidzwa nealgorithm iri nyore, isingatore nguva yakawanda, inopindura nekukurumidza, inoshanda zvakanyanya uye iri nyore kushandisa. Zvisinei, matanho ekukurumidzisa nekudzikamisa mota akafanana haaenderane nemutemo wekuchinja kumhanya kwemota ye stepper, uye nzvimbo yekuchinja pakati pekumhanya kunochinja nekumhanya kwakafanana haigone kuve yakapfava. Saka, iyi algorithm inonyanya kushandiswa mumashandisirwo apo zvinodiwa zvekukurumidza nekudzikamisa mota hazvisi zvakanyanya.
Kukurumidza uye kudzikira kweExponential curve
Tsanangudzo: Zvinoreva kukurumidza uye kudzikira kwenhamba kuburikidza nebasa re exponential.
Kukurumidza uye deceleration kudzora ongororo indekisi:
1. Kukanganisa kwenzira yemuchina nenzvimbo kunofanira kunge kudiki sezvinobvira
2. Kufamba kwemuchina kwakanaka, kuvhunduka kudiki, uye mhinduro yacho inokurumidza.
3, algorithm yekukurumidzira uye kuderedza kufambiswa kwesimba inofanira kunge iri nyore sezvinobvira, iri nyore kushandisa, uye inogona kusangana nezvinodiwa zvekudzora panguva chaiyo
Kana muchida kutaurirana uye kushanda pamwe nesu, ndapota musazeza kutibata.
Tinoshanda pamwe chete nevatengi vedu, tinoteerera zvavanoda uye tinotevedzera zvavanokumbira. Tinotenda kuti kudyidzana pakati pevatengi kunobva pamhando yezvigadzirwa uye sevhisi yevatengi.
Changzhou Vic-tech Motor Technology Co., Ltd. isangano renyanzvi rekutsvaga nekugadzira rinotarisisa kutsvagisa nekugadzira mota, mhinduro dzese dzekushandisa mota, uye kugadzirisa nekugadzira zvigadzirwa zvemota.
