Udindo wa stepper motor driver

Dalaivala wa Stepper motor ndi mtundu wa actuator womwe umatha kusintha siginecha yamagetsi kuti ikhale yosasunthika.Woyendetsa galimotoyo akalandira chizindikiro chamagetsi, amayendetsa galimoto yake kuti atembenuke kusuntha kosasunthika (timayitcha "step Angle") malinga ndi momwe adakhazikitsira poyamba, ndipo kuzungulira kwake kumayendetsedwa pang'onopang'ono ngodya yokhazikika.Titha kuwongolera kusamuka kwa Angle mwa kuwongolera kuchuluka kwa ma pulses omwe amatumizidwa, kuti tikwaniritse cholinga chokhazikitsa molondola.Panthawi imodzimodziyo, tikhoza kuwongolera kuthamanga ndi kuthamanga kwa stepper motor poyang'anira mafupipafupi a chizindikiro chake cha pulse, kuti tikwaniritse cholinga cha kuwongolera liwiro ndi kuyika.Amagwiritsidwa ntchito zosiyanasiyana makina kusema, kristalo akupera makina, sing'anga-kakulidwe CNC makina zida, EEG nsalu nsalu makina, ma CD makina, akasupe, dispensing makina, kudula ndi kudyetsa machitidwe, ndi zina zazikulu ndi sing'anga-kakulidwe.CNC zidazokhala ndi zofunikira pakusankha kwakukulu.

Nambala ya gawo la motor stepper imatanthawuza kuchuluka kwa magulu a coil mkati mwa mota ya stepper, yomwe imagwiritsidwa ntchito kwambiri magawo awiri, magawo atatu, magawo anayi, masitepe asanu.Chiwerengero cha magawo a galimoto ndi osiyana, ndi sitepe ngodya ndi yosiyana, ndi sitepe ngodya wamba awiri gawo stepper galimoto ndi madigiri 1.8, magawo atatu ndi madigiri 1.2, ndi magawo asanu ndi madigiri 0,72.Pamene stepper motor subdivision dalaivala si kukhazikitsidwa, wosuta makamaka amadalira kusankha manambala osiyana gawo la stepper motors kukwaniritsa sitepe Angle zofunika.Ngati dalaivala wogawanika akugwiritsidwa ntchito, chiwerengero cha magawo chimakhala chopanda tanthauzo, ndipo wogwiritsa ntchito akhoza kusintha sitepe Angle pokhapokha kusintha kagawo kakang'ono pa dalaivala.

Kugawikana kwa stepper galimoto dalaivala kutulutsa khalidwe kudumpha mu ntchito galimoto, koma zonsezi kwaiye dalaivala palokha, ndipo alibe chochita ndi galimoto ndi dongosolo ulamuliro.Pogwiritsidwa ntchito, mfundo yokhayo yomwe wogwiritsa ntchito amayenera kulabadira ndikusintha kwa sitepe Angle ya stepper motor, yomwe ingakhudze kuchuluka kwa masitepe omwe amaperekedwa ndi dongosolo lowongolera, chifukwa sitepe ya sitepe ya stepper motor idzakhala. kukhala yaying'ono pambuyo pa kugawa, kuchuluka kwa chizindikiro cha sitepe yopempha kuyenera kukonzedwa moyenerera.Tengani 1.8-degree stepper motor mwachitsanzo: sitepe ya dalaivala mu theka sitepe boma ndi madigiri 0,9, ndi sitepe Angle mu masitepe khumi nthawi ndi 0,18 madigiri, kuti pansi pa chikhalidwe chopempha chomwecho. Liwiro lagalimoto, ma frequency a siginecha yodutsa yomwe imatumizidwa ndi dongosolo lowongolera ndi nthawi 5 kuposa theka la theka la ntchito mu nthawi ya masitepe khumi.

Kulondola kwa motor stepper wamba ndi 3 ~ 5% ya ngodya yodutsa.Kupatuka kwapang'onopang'ono kwa stepper motor sikumakhudza kulondola kwa sitepe yotsatira, kotero kulondola kwa stepper motor sikudziunjikira.
