Pfungwa yekugadzira kupisamota yekutsika.
1, inowanzoonekwa mhando dzese dzemota, mukati mayo iron core uye winding coil.Kutenderedzwa kwemhepo kune simba, simba rinoburitsa kurasikirwa, saizi yekurasikirwa inoenderana nechiyero chesimba uye simba remagetsi, iro rinowanzonzi kurasikirwa kwemhangura, kana simba remagetsi risiri iro rakajairika reDC kana sine wave, richaburitsawo kurasikirwa kweharmonic; core ine hysteresis eddy current effect, mumunda wemagineti unochinjana uchaburitsawo kurasikirwa, saizi yaro nezvinhu, simba remagetsi, frequency, voltage, iyo inonzi kurasikirwa kwesimbi. Kurasikirwa kwemhangura uye kurasikirwa kwesimbi zvicharatidzwa muchimiro chekupisa, nokudaro zvichikanganisa kushanda kwemota. Mamota eStepper anowanzo tevera kurongeka kwenzvimbo uye kubuda kwetorque, kushanda zvakanaka kwakaderera, simba remagetsi rinowanzova rakakura, uye zvikamu zveharmonic zvakakwirira, frequency yekuchinjana kwemagetsi inosiyanawo nekumhanya, uye nekudaro mamota estepper anowanzo pisa, uye mamiriro acho akakomba kupfuura mota yeAC.
2, huwandu hwakakodzera hwemota yekutsikakupisa.
Kupisa kwemota kunobvumirwa kusvika papi, zvinonyanya kutsamira padanho rekudzivirira kwemukati memota. Kushanda kwekudzivirira kwemukati pakupisa kwakanyanya (130 degrees kana kupfuura) usati waparadzwa. Saka chero bedzi mukati memota isingapfuure 130 degrees, mota haizorasikirwi nerin'i, uye tembiricha yepamusoro ichave iri pasi pe90 degrees panguva ino.
Saka, tembiricha yepamusoro ye stepper motor iri 70-80 degrees yakajairika. Nzira iri nyore yekuyera tembiricha inobatsira point thermometer, unogona zvakare kuona kuti: neruoko unogona kubata anopfuura 1-2 seconds, kwete kupfuura 60 degrees; neruoko unogona kubata chete, anenge 70-80 degrees; madonhwe mashoma emvura anokurumidza kupwanyika, anopfuura 90 degrees.
3, mota yekutsikakupisa nekuchinja kwekumhanya.
Kana uchishandisa tekinoroji yekufambisa mota inoramba ichienderera mberi, mota dzinofamba dzichimhanya zvisina kusimba uye zvakaderera, simba remagetsi richaramba rakamira kuti rirambe riine simba remagetsi rinoramba richienderera mberi. Kana kumhanya kwacho kwakwira kusvika padanho rakati, simba remagetsi remukati memota rinokwira, simba remagetsi rinodzikira zvishoma nezvishoma, uye simba remagetsi rinodzikirawo.
Saka, mamiriro ekupisa anokonzerwa nekurasikirwa nemhangura anoenderana nekumhanya. Kumhanya kwakasimba uye kumhanya kwakaderera zvinowanzo gadzira kupisa kwakanyanya, nepo kumhanya kwakakwirira kuchigadzira kupisa kwakaderera. Asi kurasikirwa nesimbi (kunyangwe kuri kudiki) shanduko hadzina kufanana, uye mota sekupisa kwese ndiko kuunganidzwa kwezvose zviri zviviri, saka zviri pamusoro apa ingori mamiriro ezvinhu akajairika.
4, kukanganiswa kwekupisa.
Kunyangwe kupisa kwemota kazhinji kusingakanganisi hupenyu hwemota, ruzhinji rwevatengi havafanire kuiteerera. Asi zvakakomba zvichaunza mhedzisiro yakaipa. Sekusiyana kwema coefficients ekuwedzera kwekupisa kwezvikamu zvemukati memota zvinotungamira kukuchinja kwekumanikidzwa kwechimiro uye shanduko diki mugedhi remhepo yemukati, zvichakanganisa mhinduro inochinja yemota, kumhanya kwakanyanya kuchave nyore kurasikirwa nenhanho. Mumwe muenzaniso ndewekuti dzimwe nguva hazvibvumidze kupisa kwakanyanya kwemota, senge michina yekurapa nemidziyo yekuyedza yakanyatsojeka, nezvimwewo. Saka, kupisa kwemota kunofanirwa kuve kwakakosha kudzora.
5, maitiro ekuderedza kupisa kwemota.
Kuderedza kugadzirwa kwekupisa, ndiko kuderedza kurasikirwa kwemhangura uye kurasikirwa nesimbi. Kuderedza kurasikirwa kwemhangura munzira mbiri, kuderedza kuramba uye simba remagetsi, izvo zvinoda kusarudzwa kwesimba remagetsi diki uye simba remagetsi rakarongwa remota zvakanyanya sezvinobvira, mota ine zvikamu zviviri, mota inogona kushandiswa muzvikamu zvisina mota yakafanana. Asi izvi zvinowanzopesana nezvinodiwa zve torque uye kumhanya kwakanyanya. Kune mota yakasarudzwa, basa rekudzora remagetsi re automatic half-current uye basa re offline rinofanira kushandiswa zvizere, rekutanga rinoderedza simba remagetsi otomatiki kana mota yamira, uye rekupedzisira rinongodzima simba remagetsi.
Pamusoro pezvo, kupatsanurwa kwedhiraivha, nekuti waveform yazvino iri pedyo ne sinusoidal, harmonics shoma, kupisa kwemota kuchavewo kushoma. Kune nzira shoma dzekuderedza kurasikirwa kwesimbi, uye voltage level ine chekuita nayo. Kunyangwe mota inotyairwa ne high voltage ichizounza kuwedzera kwehunhu hwekumhanya kwakanyanya, inounzawo kuwedzera kwekupisa. Saka tinofanira kusarudza drive voltage level yakakodzera, tichifunga nezvekumhanya kwakanyanya, kupfava uye kupisa, ruzha nezvimwe zviratidzo.
Maitiro ekudzora ekukurumidzisa uye kuderedza mashandiro emota dzestepper.
Nekushandiswa kwakapararira kwemamota estepper, kudzidza kwekudzora mota dzestepper kuri kuwedzerawo, pakutanga kana pakumhanyisa kana stepper pulse ikachinja nekukurumidza, rotor nekuda kwekusashanda zvakanaka uye kusatevera chiratidzo chemagetsi chinoshanduka, zvichikonzera kuvharika kana kurasikirwa nedanho rekumira kana kuderera kwedanho nekuda kwechikonzero chimwe chete chinogona kukonzera kudarika. Kuti kudzivirira kuvharika, kurasikirwa nedanho uye kudarika, kuvandudza mashandiro emota yestepper kusimudza kudzora kwekumhanya.
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 pakushanda nekukurumidza. Mira kana frequency yekushanda isingaderedzwe kusvika zero, asi kuti ive nekumhanya kwakanyanya kuderedzwa zvishoma nezvishoma kusvika zero process.
Torque inobuda yemota yestepper inodzikira nekukwira kwe pulse frequency, kana frequency yekutanga yakakwira, torque yekutanga idiki, kugona kutyaira mutoro kwakaderera, kutanga kuchaita kuti nhanho irasikirwe, uye pakumira kuchaitika kana overshoot yadarika. Kuti mota yestepper isvike nekukurumidza pakumhanya kunodiwa uye isarasike nhanho kana overshoot, chinhu chakakosha ndechekuita kuti acceleration process, acceleration torque inodiwa kuti ishandise zvizere torque inopiwa nemota yestepper pane imwe neimwe frequency yekushanda, uye kuti isapfuure torque iyi. Naizvozvo, mashandiro emota yestepper anowanzo fanirwa kupfuura nekumhanya, kumhanya kwakafanana, kudzikamisa nhanho nhatu, nguva yekukasira nekudzikamisa nhanho pfupi sezvinobvira, nguva yekukasira nguva dzose yakareba sezvinobvira. Kunyanya mubasa rinoda mhinduro nekukurumidza, kubva pakutanga kusvika kumagumo kwenguva yekumhanya inodiwa kuti ive pfupi, iyo inofanirwa kuda kukurumidza, maitiro ekudzikamisa ndiyo pfupi, nepo kumhanya kwepamusoro pakumhanya nguva dzose.
Masayendisiti nematekiniki vari kumusha nekune dzimwe nyika vakaita tsvakurudzo yakawanda pamusoro pe tekinoroji yekudzora kumhanya kwemamota estepper, uye vakagadzira mhando dzakasiyana dzemamota ekugadzirisa kumhanya uye kuderedza kutenderera, senge exponential model, linear model, nezvimwewo, uye zvichibva pakugadzirwa uku nekugadzirwa kwemasekitori akasiyana-siyana ekudzora kuti vavandudze hunhu hwekufamba kwemamota estepper, kukurudzira kushandiswa kwemamota estepper. Kukurumidza kukuru uye kuderedza kutenderera kunotora pfungwa dzehunhu hwenguva-pfupi hwemota dzestepper, zvese kuve nechokwadi chekuti mota yestepper iri kufamba isina kurasikirwa nenhanho, asiwo kupa kutamba kwakazara kune hunhu hwemota, kupfupisa nguva yekumhanya, asi nekuda kwekuchinja kwemutoro wemota, zvakaoma kuita nepo kumhanyisa kwemutsara uye kuderedza kutenderera kunongofunga nezvemota iri muhuwandu hwemutoro we angular velocity uye pulse zvinoenderana nehukama uhwu, kwete nekuda kwekuchinja kwevoltage yekugovera, nharaunda yemutoro uye hunhu hwekuchinja, nzira iyi yekumhanyisa kumhanya inogara iripo, dambudziko nderekuti haifungi zvizere nezve torque yekubuda kwemota yestepper. Nehunhu hwekuchinja kwekumhanya, mota yestepper pakumhanya kwakanyanya ichabuda padanho.
Iyi inyaya yekutanga papfungwa yekudziyisa uye tekinoroji yekudzora kukurumidza/kudzikisa mashandiro emota dzinofamba netsoka.
Kana muchida kutaurirana uye kushanda pamwe nesu, ndapota inzwa wakasununguka kutibata!
Tinoshanda pamwe chete nevatengi vedu, tichiteerera zvavanoda uye tichiita zvavanokumbira. Tinotenda kuti kudyidzana pakati pevatengi kunobva pamhando yezvigadzirwa uye sevhisi yevatengi.
