I-Electronics Component Original IC LC898201TA-NH

incazelo emfushane:

I-LC898201 iyi-LSI elawulwa yi-motor yamakhamera agadayo ashayela kanyekanye iris, ukusondeza, ukugxila, nokushintsha kwemini/ubusuku.Ihlanganisa amasekhethi amabili empendulo we-iris nokulawula okugxilwe kuwo, kanye namasekethe okulawula izitebhisi ezimbili zokusondeza nokushintsha imini/ubusuku.Futhi, ngaphansi kokukhethwa kwemodi, ukulawulwa kwempendulo kusetshenziselwa ukulawulwa kwe-iris kanye nokulawulwa kwe-stepper motor kusetshenziselwa ukusondeza, ukugxila, nokushintsha imini/busuku.

Isingeniso

Umshayeli wemoto uyishintshi, ngoba idrayivu yemoto yamanje inkulu kakhulu noma i-voltage iphezulu kakhulu, futhi inkinobho evamile noma izingxenye ze-elekthronikhi azikwazi ukusetshenziswa njengeswishi yokulawula injini.

Iqhaza lomshayeli wemoto: Indima yomshayeli wemoto isho indlela yokufinyelela ekulawuleni isivinini sokungenzi lutho semoto ngokulawula i-engeli yokuzungezisa kanye nesivinini sokusebenza semoto, ukuze kuzuzwe ukulawula umjikelezo womsebenzi.

I-motor drive circuit schematic circuit diagram: Isekethe ye-motor drive ingashayelwa ngokudluliswa kwe-relay noma i-transistor yamandla, noma ngokusebenzisa i-thyristor noma i-MOS FET yamandla.Ukuze uvumelane nezidingo ezahlukene zokulawula (njengamanje ukusebenza kanye ne-voltage yemoto, ukulawulwa kwejubane lemoto, ukulawulwa okuya phambili nokuhlehla kwemoto ye-DC, njll.), izinhlobo ezahlukene zamasekhethi okushayela kwezimoto kufanele zihlangabezane nezidingo izidingo ezifanele.

Imoto kagesi ayiqali uma isinamandla, futhi kuba nzima ukuyiphusha futhi ihambisana nomsindo "wokuminyanisa".Lesi simo siwukuthi ikhebula le-motor lifushane ngenxa yokuxhumana noxhumo olubonakalayo, futhi umkhuba wokusunduza inqola ngemigqa emithathu yesigaba esiwugqinsi senjini ingakhishwa bese inyamalala, okubonisa ukuthi isilawuli siphukile futhi sidinga ukumiswa. ishintshwe ngesikhathi.Uma kusenzima ukukusebenzisa, kusho ukuthi kunenkinga ngenjini, futhi kungenzeka kubangelwe ukushiswa komjikelezo omfushane wekhoyili yenjini.
