I-Stepper motors yenye yeenjini ezilula ukuphunyezwa kwiinkqubo zobugcisa apho kukho izinga lokuchaneka nokuphindaphinda. Ngelishwa, ukwakhiwa kweenjini ezihamba phambili zibeka umda wokunciphisa isivinini kwisithuthi, esingaphantsi kwesantya i-elektroniki inokuqhuba i-motor. Xa ukuqhutyelwa kwejubane eliphezulu kwi-motor stepper kuyadingeka ukuba kunzima ukuphunyezwa ukunyuka njengoko inani lezinto ziqala ukungena.
Iinqwelo eziPhezulu zeZithuthi eziPhezulu
Imiba emininzi ibe yinkqubo ebalulekileyo kunye neengxaki zokuphunyezwa xa iimoto ezihamba phambili ziqhutywa ngokukhawuleza. Njengamacandelo amaninzi, ukuziphatha kwangempela kwehlabathi kwama-stepper motors akulungele kwaye kukude kakhulu kwimbono. Isantya se- stepper max speed siyahluka ngokuvelisa umenzi, imodeli, kunye nokukhutshwa kwemoto ngezantya ze-1000-3000 RPM ezinokufumaneka (ukuphakama okuphakamileyo, i- servo motors yinto ekhethekileyo). Izinto eziphambili ezichaphazela ukuqhubela umqhubi wemoto ngesivinini esiphezulu zi:
- Inertia - Nayiphi na into ehambayo inertia ephikisana nokutshintsha kwento. Kwizantya ezisezantsi, kunokwenzeka ukuba uqale ukuqhuba umqhubi we-stepper kwisantya esifunayo ngaphandle kokulahleka inyathelo. Nangona kunjalo, ukuzama ukuqhuba umthwalo kwi-stepper motor ngesivinini esikhulu ngokukhawuleza kuyindlela enhle yokweqa amanqanaba kwaye ulahlekelwe isikhundla. Ngaphandle kwimizimba yesisindo esincinci esineempembelelo ezincinci, i-stepper motor kufuneka inyuke kwisantya esiphantsi ukuya kwisivinini esiphezulu ukugcina indawo kunye nokuchaneka. Ukulawulwa kweemoto ezithuthukisayo eziphambili kufaka ukunciphisa ukukhawuleza kunye nobuchule bokuhlawulela inertia.
- I-Torque Curves - I-torque ye-motor stepper ayifani nayo yonke isivinini sokusebenza kodwa iyancipha njengoko isantya sokunyuka sisanda. Isizathu salo sisekelwe kwiinqununu zokusebenza zee-motor motors. I-signal drive yokuqhuba i-stepper motors ivelisa i-magnetic field kwiikhoyili ze-motor ukwenzela ukudala amandla ukuthatha inyathelo. Ixesha elithatha inkundla yamagneti ukuba ifikelele ekuxhaseni ngokupheleleyo kuxhomekeke ekungeneni kwekhoyili, ukuqhutshwa kwamandla okuqhuba, kunye nokunciphisa kwamanje. Njengoko ijubane lokushayela likhuphuka, ixesha lokuphephelela kwamakhoyili lihlala liphelile ngamandla kwaye i-torque i-motor iyakhupha amaconsi.
- I-Signal Drive - Ukuze ukwandise amandla kumqhubi we-stepper, umqondiso we-drive okhoyo ngoku kufuneka ufikelele kwi-drive ephezulu ngoku kunye nezicelo ezikhawulezileyo ezi zinto kufuneka zenziwe ngokukhawuleza. Ukuqhuba umqhubi we-stepper ngesigxina esiphezulu sombane kunokunceda ukuphucula i-torque ngokukhawuleza okusetyenziswe ngokuzenzekelayo kwizixazululo zokuqhuba umqhubi zangoku.
- Uluhlu olufileyo - Umbono ochanekileyo wemoto uvumela ukuba uqhutywe kuyo nayiphi na isivinini ngokubhekiselele ekunciphiseni kwebhola njengoko ijubane landa. Ngelishwa, ii-motors ezihamba phambili zihlala kwindawo efile apho imoto ayikwazi ukuqhuba umthwalo kwisantya esinikeziwe. Oku kubangelwe ukuhlaziya kwinkqubo kwaye ihlukahluka kuyo yonke imveliso kunye noyilo.
- Ukulungiswa kwezinto - ii-Stepper motors zokuqhuba iinkqubo zokucwangcisa kunye nazo zonke iinkqubo zokucwangcisa ziyakwazi ukuxhamla kwi-resonance. Ukuhlaziya kwenzeka xa i-frequency yokuqhuba ihambelana nokuvakala kwendalo kunye nefuthe lamandla kwinkqubo inokunyusa ukunyakaza kwayo kunye nokulahleka kwebhanki kunokuba ifikelele. Kwizicelo apho ukugungqiswa okugqithiseleyo kuya kuba nemiba, ukufumana nokunyuka kwi-speed resonance stepper ngesivinini kubaluleke kakhulu. Nokuba izicelo ezikwazi ukunyamezela ukunyakaza kufuneka ziphephe i-resonance apho kunokwenzeka khona kuba inokunciphisa kakhulu impilo yenkqubo.
- Ubukhulu Bamanyathelo - Amashishini ase Stepper anamaqhinga ambalwa okuqhuba, kuquka ukuhamba okuncinci okuvumela ukuba amancinci angaphezu kwamanyathelo apheleleyo ayenziwe ngumqhubi. Amanyathelo amancinci anganikezeli ukuchaneka okwandisiweyo (kunokuba amanyathelo amancinci ayancipha ukuchaneka) kodwa enza i-stepper motor isebenze ngokukhawuleza ngesantya esezantsi. Iimoto ze-stepper ziyakwazi ukuqhutyelwa kuphela ngokukhawuleza, kwaye imoto ayiboni ehlukileyo kumanyathelo amancinci okanye isinyathelo esipheleleyo. Ukusebenza ngokukhawuleza, ukuqhuba i-stepper motor ngamanyathelo apheleleyo kuyafuneka. Nangona kunjalo, ukusebenzisa i-micro encinci kwi-curf acceleration curve kunganciphisa kakhulu ingxolo kunye nokunyakaza kwenkqubo.
