Kuyaziwa kakhulu ensimini yobunjiniyela ukuthi ukubekezelela kwemishini kunomthelela omkhulu ngokunemba nokunemba kwalo lonke uhlobo lwedivayisi engacatshangwa kungakhathalekile ukusetshenziswa kwayo. Leli qiniso likhona futhiI-Stepper Motors. Isibonelo, i-stepper motor eyakhiwe inezinga lokubekezelela cishe cishe amaphutha angama-5% amahlanu ngesinyathelo. Lawa amaphutha angewona aqongelelayo ngendlela. Iningi lama-motors e-stepper ahambisa ama-degree angu-1.8 ngesinyathelo ngasinye, aphumela ebangeni lephutha elingaba khona lama-0.18 degrees, noma ngabe sikhuluma ngezinyathelo ezingama-200 zokujikeleza (bheka umfanekiso 1).
2-isigaba Stepper Motors - Uchungechunge lwe-GSSD
I-miniaturature igxuma ngokunemba
Ngokunemba, ukunemba okungafanele, ukunemba kwamaphesenti ama-5, indlela yokuqala nenengqondo kakhulu yokwandisa ukunemba kuyisenyatho esincane. I-Micro Spapping iyindlela yokulawula ama-motor we-stepper afinyelela hhayi kuphela ukulungiswa okuphezulu kepha ukunyakaza okubushelelezi ngejubane eliphansi, okungenzeka kube yinzuzo enkulu kwezinye izinhlelo.
Ake siqale nge-angle yethu yesinyathelo esingu-1.8-degree. Leli angle step lisho ukuthi njengoba imoto ithatha isinyathelo ngasinye iba yingxenye enkulu kukho konke. Ngokuhamba kancane kanye nejubane elihamba kancane, usayizi wesinyathelo omkhulu ubangela ukucaga emotweni. Enye indlela yokunciphisa lokhu kuncipha kokusebenza okunciphile ku-Slow Speeds ukunciphisa usayizi wesinyathelo ngasinye semoto. Yilapho i-Micro Opping iba yinto ebalulekile.
Ukungena kwe-Micro Kutholakala ngokusebenzisa i-Pulse-Width kulungiselelwe (PWM) ukulawula okwamanje kuma-motor windings. Kwenzekani ukuthi umshayeli we-motor uhambisa amagagasi ama-voltage ama-vol anamanzi amabili kumagagasi e-motor, ngakunye kwawo okungama-90 degrees ngaphandle kwenye. Ngakho-ke, ngenkathi kukhuphuka kwamanje ngomoya owodwa, kuncipha kolunye umoya ukukhiqiza ukudluliswa okuthe xaxa kwamanje, okuholela ekukhiqizweni okugcwele okuthe xaxa nokukhiqizwa okujwayelekile okukodwa (bheka isinyathelo 2).
I-Single-AxisI-Stepper Motor Controller + Driver isebenza
Lapho unquma ngokwanda ngokunemba okusekelwe ku-Micro Opting Control, onjiniyela kufanele babheke ukuthi lokhu kuthinta kanjani ezinye izici zezimoto. Ngenkathi ubushelelezi bokulethwa kwe-torque, ukunyakaza okusheshayo okusheshayo, futhi kungavuselelwa kabusha kusetshenziswa i-microsing spapping, ukulinganiselwa okujwayelekile ekulawulweni kanye nedizayini yezimoto kungavimba ekufinyeleleni izici zazo ezinhle kakhulu. Ngenxa yokusebenza kwemoto ye-stepper, ukushayela okumaphakathi kwe-microsing kungalinganiswa kuphela i-wave yangempela ye-sine. Lokhu kusho ukuthi i-torque ripple, i-resonance, nomsindo kuzosala ohlelweni yize ngayinye yalokhu incishiswa kakhulu emsebenzini we-micropping.
Ukunemba Kwemishini
Olunye ushintsho olwenziwe ngomshini lokuthola ukunemba emotweni yakho ye-stepper ukusebenzisa umthwalo omncane we-inertia. Uma imoto inamathiselwe kwi-inertia enkulu lapho izama ukuyeka, umthwalo uzobangela ukujikeleza kancane. Ngoba lokhu kuvame ukuba yiphutha elincane, isilawuli sezimoto singasetjenziselwa ukululungisa.
Ekugcineni, sibuyela emuva kulawulo. Le ndlela ingathatha umzamo wobunjiniyela. Ukuze uthuthukise ukunemba, ungahle ufune ukusebenzisa isilawuli esilungiselelwe ngokukhethekile ngemoto oyikhethile ukuyisebenzisa. Le yindlela eqondile kakhulu yokufaka. Ikhono elingcono lokulawulwa kokukhohlisa indawo yamanje yemoto ngokunemba, ukunemba okuthe xaxa ongakuthola ku-motor peter oyisebenzisayo. Lokhu kungenxa yokuthi isilawuli silawula kahle ukuthi mangaki amakhandlela motor windings athola ukuqala ukunyakaza okuqhubekayo.
Ukunemba ezinhlelweni zokunyakaza kuyimfuneko ejwayelekile ngokuya ngesicelo. Ukuqonda ukuthi uhlelo lwe-stepper lusebenza kanjani ndawonye ukudala ukunemba kuvumela unjiniyela ukuthi asebenzise ubuchwepheshe obukhona, kufaka phakathi lezo ezisetshenziswa ekwakhiweni kwezinto zomshini ngamunye.
