I-Electronics Component Original IC LC898201TA-NH

inkcazelo emfutshane:

I-LC898201 yi-LSI elawulwa yimoto yeekhamera zokucupha eziqhuba i-iris ngaxeshanye, i-zoom, igxininise, kunye nokutshintsha kwemini/ubusuku.Idibanisa iisekethe ezimbini zeempendulo ze-iris kunye nolawulo logxininiso, kunye neesekethe ezimbini zolawulo lweemoto zokusondeza kunye nokutshintsha kwemini / ubusuku.Kwakhona, phantsi kokhetho lwemowudi, ulawulo lwempendulo lusetyenziselwa ulawulo lwe-iris kunye nolawulo lwe-stepper motor lusetyenziselwa ukusondeza, ukugxila, kunye nokutshintsha kwemini / ubusuku.

Intshayelelo

Umqhubi wemoto utshintshi, ngenxa yokuba i-motor drive yangoku inkulu kakhulu okanye i-voltage iphezulu kakhulu, kwaye iswitshi ngokubanzi okanye izinto ze-elektroniki azinakusetyenziswa njengento yokutshintsha ukulawula imoto.

Indima yomqhubi wemoto: Indima yomqhubi wemoto ibhekisa kwindlela yokufikelela kulawulo lwesantya sokungenzi nto ngemoto ngokulawula i-engile yokujikeleza kunye nesantya sokusebenza semoto, ukuze kufezekiswe ulawulo lomjikelo womsebenzi.

I-Motor drive circuit circuit schematic diagram: I-motor drive circuit ingaqhutywa nokuba yi-relay okanye i-transistor yamandla, okanye ngokusebenzisa i-thyristor okanye i-MOS FET yamandla.Ukuze ulungelelanise iimfuno zolawulo ezahlukeneyo (ezinje ngokusebenza kwangoku kunye nombane wemoto, ukulawulwa kwesantya semoto, ukuya phambili kunye nokulawulwa ngasemva kwemoto yeDC, njl.njl.), iintlobo ezahlukeneyo zeesekethe zokuqhuba iimoto kufuneka zihlangane iimfuno ezifanelekileyo.

Isithuthi sombane asiqalisi xa sinikwe amandla, kwaye kuba nzima ngakumbi ukutyhala kunye nokukhatshwa sisandi "sokuminxa".Le meko kukuba intambo yemoto imfutshane-ijikelezwe ngenxa yokunxibelelana noqhagamshelo lwenyani, kwaye isenzeko sokutyhala inqwelo ngemigca emithathu eshinyeneyo yemoto inokukhutshwa kwaye ilahleke, ebonisa ukuba umlawuli waphukile kwaye kufuneka zitshintshwe ngexesha.Ukuba kusenzima ukuphumeza, kuthetha ukuba kukho ingxaki nge-motor, kwaye inokubangelwa yi-short circuit ye-coil motor etshiswayo.
