Ndizodziwika bwino pankhani yaukadaulo kuti kulolerana kwamakina kumakhudza kwambiri kulondola komanso kulondola kwamtundu uliwonse wa chipangizo chomwe mungachiganizire mosasamala kanthu za kugwiritsidwa ntchito kwake. Mfundo imeneyi ndi zoonama stepper motors. Mwachitsanzo, injini yokhazikika yomanga stepper ili ndi mulingo wololera pafupifupi ± 5 peresenti cholakwika pa sitepe iliyonse. Izi ndi zolakwika zosadzikundikira mwa njira. Ma motors ambiri amasuntha madigiri 1.8 pa sitepe iliyonse, zomwe zimapangitsa kuti pakhale cholakwika cha madigiri 0.18, ngakhale tikukamba za masitepe 200 pa kasinthasintha (onani Chithunzi 1).
2-Phase Stepper Motors - GSSD Series
Masitepe Aang'ono Kuti Akhale Olondola
Ndi mulingo wokhazikika, wosaphatikizika, wolondola wa ± 5 peresenti, njira yoyamba komanso yomveka yowonjezerera kulondola ndikuyimitsa injini yaying'ono. Kutsika kwa Micro ndi njira yowongolera ma stepper motors omwe amakwaniritsa osati kusintha kwakukulu koma kuyenda kosalala pama liwiro otsika, komwe kumatha kukhala phindu lalikulu pamapulogalamu ena.
Tiyeni tiyambe ndi mbali yathu ya 1.8-degree step angle. Njirayi imatanthawuza kuti pamene injini imachedwetsa sitepe iliyonse imakhala gawo lalikulu la lonse. Pakuthamanga pang'onopang'ono komanso pang'onopang'ono, kukula kwake kwakukulu kumapangitsa kuti injiniyo ikhale yolimba. Njira imodzi yochepetsera kusalala kotereku koyenda pang'onopang'ono ndikuchepetsa kukula kwa sitepe iliyonse yagalimoto. Apa ndipamene micro stepping imakhala njira yofunikira.
Kutsika kwapang'onopang'ono kumatheka pogwiritsa ntchito pulse-width modulated (PWM) kuwongolera zomwe zikuchitika pamayendedwe amagalimoto. Zomwe zimachitika ndikuti dalaivala wagalimoto amatulutsa mafunde awiri a voltage sine ku ma windings a motor, iliyonse yomwe ili ndi madigiri 90 kunja kwa gawo ndi inzake. Chifukwa chake, ngakhale kuwonjezereka kwaposachedwa pamapiringidwe amodzi, kumachepera pakumangirira kwina kuti kupangitse kusamutsa kwaposachedwa, komwe kumapangitsa kuyenda kosavuta komanso kupanga ma torque mosadukiza kuposa momwe munthu angatengere kuchokera pamlingo wathunthu (kapena ngakhale wamba theka) kuwongolera. (onani Chithunzi 2).
mzere umodzistepper motor controller + driver imagwira ntchito
Posankha pakukula kolondola kutengera kuwongolera kwapang'onopang'ono, mainjiniya amayenera kuganizira momwe izi zimakhudzira mawonekedwe ena onse agalimoto. Ngakhale kufewa kwa ma torque, kuyenda pang'onopang'ono, komanso kumveka bwino kumatha kupitsidwanso pogwiritsa ntchito mayendedwe ang'onoang'ono, zolephera zomwe zimawongolera komanso kapangidwe ka mota zimawalepheretsa kufikira mawonekedwe awo onse. Chifukwa chakugwira ntchito kwa ma stepper motor, ma micro stepping drives amatha kungoyerekeza ndi sine wave weniweni. Izi zikutanthauza kuti ma torque, ma resonance, ndi phokoso likhalabe m'dongosolo ngakhale chilichonse mwa izi chimachepetsedwa kwambiri pakadutsa pang'ono.
Kulondola Kwamakina
Kusintha kwina kwamakina kuti mukhale olondola mu stepper motor yanu ndikugwiritsa ntchito inertia yocheperako. Ngati galimotoyo imangiriridwa ndi inertia yaikulu pamene ikuyesera kuyimitsa, katunduyo amachititsa kuti azizungulira pang'ono. Chifukwa ichi nthawi zambiri chimakhala cholakwika chaching'ono, chowongolera chamoto chingagwiritsidwe ntchito kukonza.
Pomaliza, tibwereranso ku controller. Njira iyi ingafunike khama laukadaulo. Kuti muwongolere kulondola, mungafune kugwiritsa ntchito chowongolera chomwe chimakongoletsedwa ndi injini yomwe mwasankha kugwiritsa ntchito. Iyi ndi njira yolondola kwambiri yophatikizira. Kuthekera kwa wowongolera kuyendetsa bwino injini yamagetsi, m'pamenenso mungapeze kulondola kwambiri kuchokera pa stepper motor yomwe mukugwiritsa ntchito. Izi ndichifukwa choti wowongolera amawongolera ndendende kuchuluka kwa ma windings a injini kuti ayambitse kuyenda.
Kulondola kwamachitidwe oyenda ndikofunikira wamba kutengera momwe akugwiritsira ntchito. Kumvetsetsa momwe ma stepper system amagwirira ntchito limodzi kuti apange kulondola kumalola injiniya kupezerapo mwayi pa matekinoloje omwe alipo, kuphatikiza omwe amagwiritsidwa ntchito popanga zida zamakina agalimoto iliyonse.
