Makhalidwe a Stepper Motors

01

Ngakhale pa motor stepper yomweyi, mawonekedwe anthawi-kawirikawiri amasiyana kwambiri mukamagwiritsa ntchito ma drive osiyanasiyana.

Pamene makwerero akugwira ntchito, zizindikiro za pulse zimawonjezeredwa ku mapiringidzo a gawo lililonse motsatira dongosolo linalake (momwe ma windings amapatsidwa mphamvu ndi kuchotsedwa mphamvu ndi wogawa mphete mkati mwa dalaivala).

Ma steping motor ndi osiyana ndi ma motors ena, ma voliyumu ake omwe adavotera komanso omwe adavotera panopa ndizomwe zimangotanthauza; ndipo chifukwa chopondapo chimayendetsedwa ndi ma pulses, voteji yamagetsi ndimagetsi ake apamwamba kwambiri, osati ma voliyumu wamba, motero mota yolowera imatha kugwira ntchito mopitilira momwe idavotera. Koma zosankhidwazo siziyenera kupatuka patali kwambiri ndi mtengo wake.

Ma steping motor ilibe cholakwika chodziunjikira: nthawi zambiri kulondola kwa injini yopondapo kumakhala magawo atatu kapena asanu mwa magawo enieni, ndipo sikumawunjika.

Kutentha kwakukulu kovomerezeka kwa mawonekedwe agalimoto: kutentha kwakukulu kwa masitepe opondapo kumayamba kutulutsa maginito amagetsi agalimoto, zomwe zimatsogolera kutsika kwa torque kapena kutsika, kotero kutentha kovomerezeka kwa mawonekedwe agalimoto kuyenera kudalira gawo la demagnetization lazinthu zamaginito zamagalimoto osiyanasiyana; zambiri, demagnetization mfundo ya zinthu maginito ndi kuposa madigiri 130 Celsius, ndipo ena a iwo mpaka kufika madigiri oposa 200 Celsius, choncho, n'zachilendo kwathunthu kuti makwerero galimoto kukhala ndi kutentha 80-90 madigiri Celsius mu maonekedwe. Choncho, kutentha kwa makwerero amoto akunja ndi 80-90 madigiri Celsius ndi abwinobwino.

Makokedwe amotowo adzachepa ndi kuchuluka kwa liwiro lozungulira: pomwe chopondapo chikuzungulira, kuwongolera kwa mafunde a gawo lililonse la mota kumapanga mphamvu yosinthira ma electromotive; kumtunda kwafupipafupi, kumapangitsanso mphamvu ya reverse electromotive. Pansi pakuchita kwake, gawo lamagetsi lamagetsi limatsika ndikuwonjezeka pafupipafupi (kapena liwiro), zomwe zimapangitsa kuchepa kwa torque.

Kuponda galimoto akhoza kuthamanga bwinobwino pa liwiro otsika, koma ngati apamwamba kuposa pafupipafupi wina sangakhoze kuyamba, ndi limodzi ndi mluzu phokoso. Kutsika galimoto ali ndi luso chizindikiro: palibe katundu chiyambi pafupipafupi, ndiko kuti, poponda galimoto mu palibe katundu zinthu akhoza kuyamba zimachitika pafupipafupi, ngati zimachitika pafupipafupi kuposa mtengo, galimoto sangathe kuyamba bwinobwino, akhoza kuchitika sitepe imfa kapena kutsekereza. Pankhani ya katundu, mafupipafupi oyambira ayenera kukhala ochepa. Ngati galimotoyo ifike pa liwiro lalikulu, kugunda kwafupipafupi kuyenera kufulumizitsidwa, mwachitsanzo, mafupipafupi oyambira ayenera kukhala otsika, ndiyeno apititse patsogolo maulendo apamwamba omwe amafunidwa (mothamanga kuchokera pansi mpaka pamwamba).

Magetsi amagetsi oyendetsa ma hybrid stepper motor nthawi zambiri amakhala osiyanasiyana, ndipo magetsi operekera nthawi zambiri amasankhidwa malinga ndi liwiro la mota komanso momwe amayankhira. Ngati liwiro lagalimoto lagalimoto ndilokwera kwambiri kapena kuyankhako kuli mwachangu, ndiye kuti mtengo wamagetsi ndiwokwera, koma samalani kuti kuphulika kwamagetsi amagetsi kuyenera kupitilira kuchuluka kwamagetsi a dalaivala, apo ayi dalaivala akhoza kuwonongeka.

Mphamvu zamagetsi nthawi zambiri zimatsimikiziridwa molingana ndi gawo lotulutsa I la dalaivala. Ngati magetsi akugwiritsidwa ntchito, magetsi amatha kutengedwa ngati 1.1 mpaka 1.3 nthawi za I. Ngati magetsi akugwiritsidwa ntchito, magetsi amatha kutengedwa ngati 1.5 mpaka 2.0 nthawi za I.

Chizindikiro chapaintaneti cha UFULU chikakhala chochepa, zotulutsa zapano kuchokera kwa dalaivala kupita ku mota zimadulidwa ndipo rotor yamoto imakhala yaulere (yopanda intaneti). Pazida zina zodzichitira zokha, ngati kusinthasintha kwachindunji kwa shaft yamoto (mawonekedwe amanja) kumafunika popanda kuyendetsa galimotoyo kukhala ndi mphamvu, chizindikiro cha UFULU chitha kuyikidwa chotsika kuti injiniyo isagwire ntchito pamanja kapena kuyisintha. Pambuyo pogwira ntchito pamanja, chizindikiro cha UFULU chimakhazikitsidwanso kuti mupitilize kudziwongolera.

Njira yosavuta yosinthira kayendedwe ka injini yagawo ziwiri ikapatsidwa mphamvu ndikusintha mawaya A+ ndi A- (kapena B+ ndi B-) a mawaya a injini ndi oyendetsa.
