Kuyaziwa kwintsimi yobunjineli ukuba ukunyamezela koomatshini kunempembelelo enkulu ekuchanekeni kunye nokuchaneka kulo lonke uhlobo lwesixhobo esicingelwayo kungakhathaliseki ukuba lusetyenziswe njani. Le nyaniso ikwayinyanisoiinjini ze-stepper. Umzekelo, umgangatho owenziweyo we-stepper motor unenqanaba lokunyamezela malunga ne-± 5 yepesenti yempazamo ngenyathelo ngalinye. Ezi ziziphoso ezingaqokeleliyo ngendlela. Uninzi lweemotor ezinyathelayo zihamba nge-1.8 degrees ngenyathelo ngalinye, nto leyo ekhokelela kuluhlu lwempazamo olunokubakho lwe-0.18 degrees, nangona sithetha ngamanyathelo angama-200 ngokujikeleza (jonga uMfanekiso 1).

Ukunyathela okuncinci kokuChaneka
Ngomgangatho oqhelekileyo, onganyukiyo, ukuchaneka kwe-± 5 ekhulwini, eyona ndlela yokuqala kunye neyona ndlela inengqiqo yokwandisa ukuchaneka kukunyathela nge-micro step motor. Ukunyathela ngeMicro yindlela yokulawula iimotor ezinyathelayo ezingaphumeleliyo kuphela kwisisombululo esiphezulu kodwa intshukumo egudileyo kwizantya eziphantsi, ezinokuba lulutho olukhulu kwezinye izicelo.
Masiqale nge-engile yethu ye-1.8-degree step. Le angle yenyathelo ithetha ukuba njengoko injini icotha inyathelo ngalinye liba yinxalenye enkulu yalo lonke. Ngezantya ezicothayo nezicothayo, ubungakanani benyathelo elikhulu kakhulu bubangela ukuxinana kwemoto. Enye indlela yokunciphisa oku kwehla kokuguda komsebenzi ngesantya esicothayo kukunciphisa ubungakanani benyathelo ngalinye lemoto. Kulapho i-micro stepping iba yeyona ndlela ibalulekileyo.
Ukunyathela okuncinci kuphunyezwa ngokusebenzisa i-pulse-width modulated (PWM) ukulawula umsinga ukuya kwiimotor windings. Yintoni eyenzekayo kukuba umqhubi wemoto uhambisa amaza ombane amabini e-sine kwiimotor windings, nganye kuzo i-90 degrees ngaphandle kwesigaba kunye nenye. Ke, ngelixa ukonyuka kwangoku kwi-winging enye, kuyancipha kwelinye ukujija ukuvelisa ukuhanjiswa okuthe ngcembe kwangoku, okukhokelela kwintshukumo egudileyo kunye nemveliso yetorque engaguqukiyo kunokuba umntu uya kufumana kwinyathelo elipheleleyo eliqhelekileyo (okanye nakwinqanaba eliqhelekileyo lesiqingatha) ulawulo. (jonga umfanekiso 2).

Xa kuthathwa isigqibo malunga nokonyuka kokuchaneka okusekwe kulawulo lokunyathela oluncinci, iinjineli kufuneka ziqwalasele ukuba oku kuzichaphazela njani ezinye iimpawu zemoto. Ngelixa ukugudiswa kokuhanjiswa kwetorque, isantya esisezantsi, kunye neresonance inokuphuculwa kusetyenziswa ukunyathela okuncinci, imida eqhelekileyo kulawulo kunye noyilo lwemoto lubathintela ekufikeleleni kwiimpawu zabo ezigqibeleleyo. Ngenxa yokusebenza kwemoto ye-stepper, i-micro stepping drives inokuqikelela kuphela i-sine wave yokwenyani. Oku kuthetha ukuba enye i-torque ripple, i-resonance, kunye nengxolo iya kuhlala kwi-system nangona nganye kwezi iyancipha kakhulu kwi-micro stepping operation.
Ukuchaneka koomatshini
Olunye uhlengahlengiso lomatshini ukuze ufumane ukuchaneka kwimotor yakho yokunyathela kukusebenzisa umthwalo omncinci we-inertia. Ukuba i-motor ifakwe kwi-inertia enkulu xa izama ukuyeka, umthwalo uya kubangela ukujikeleza okuncinci. Kuba oku kuhlala kuyimpazamo encinci, isilawuli semoto singasetyenziselwa ukuyilungisa.
Ekugqibeleni, sibuyela kumlawuli. Le ndlela inokuthatha iinzame zobunjineli. Ukuze uphucule ukuchaneka, unokufuna ukusebenzisa isilawuli esilungiselelwe ngokukodwa imoto oyikhethileyo ukuyisebenzisa. Le yindlela echanekileyo kakhulu yokudibanisa. Okukhona umlawuli ekwazi ukwenza ngcono imotor yangoku ngokuchanekileyo, kokukhona uchaneka ngakumbi onokukufumana kwi-stepper motor oyisebenzisayo. Oku kungenxa yokuba umlawuli ulawula ngokuthe ngqo ukuba ingakanani na yangoku i-motor windings efunyanwayo ukuqalisa intshukumo.
Ukuchaneka kwiinkqubo ezishukumayo yimfuneko eqhelekileyo ngokuxhomekeke kwisicelo. Ukuqonda indlela inkqubo ye-stepper esebenza ngayo kunye ukuze idale ukuchaneka kuvumela injineli ukuba ithathe ithuba lobuchwepheshe obukhoyo, kubandakanya nezo zisetyenzisiweyo ekudaleni amacandelo oomatshini kwimoto nganye.
