I-PWM (Pulse Width Modulation) iyindlela esetshenziswa kabanzi ukulawula isivinini kanye namandla okudlidliza kwama-DC noma ama-vibration motors. Uma kusetshenziswa isignali ye-PWM evamise ukuba phezulu kumoto, i-voltage ejwayelekile eqhuba imoto yileyo signali. Lokhu kuvumela ukulawulwa okunembile kwesivinini semoto kanye namandla okudlidliza. Iyithuluzi elibalulekile ezinhlobonhlobo zezicelo okuhlanganisa amarobhothi, imishini yezimboni, kanye nama-electronics abathengi.
Qonda izisekelo zezimpawu ze-PWM
Ukuze usebenzise i-PWM ukulawula isivinini namandla okudlidliza enjini, kubalulekile ukuqonda izisekelo zezibonakaliso ze-PWM. Isignali ye-PWM iqukethe uchungechunge lwama-pulse, lapho ububanzi be-pulse (obubizwa ngokuthi umjikelezo womsebenzi) bunquma i-voltage ejwayelekile esetshenziswa enjinini. Ngokulungisa umjikelezo womsebenzi wesignali ye-PWM, i-voltage esebenzayo kanye nogesi olethwa enjinini kungalawulwa, ngaleyo ndlela kulungiswe isivinini namandla okudlidliza enjini.
Uma usebenzisa i-PWM ku-imoto yokudlidliza yohlamvu lwemali, imvamisa yesignali ye-PWM idlala indima ebalulekile ekunqumeni ukusebenza kwenjini. Amaza aphezulu e-PWM avumela ukulawula okubushelelezi nokunembile kwejubane lenjini kanye namandla okudlidliza. Ngaphezu kwalokho, imvamisa ye-PWM kufanele ikhethwe ngokucophelela ukuze kugwenywe noma yimiphi imiphumela engathandeki njengomsindo ozwakalayo noma ukukhala komshini enjinini.
Isibonelo senjini eqhutshwa yisiginali ye-PWM
Khetha isilawuli se-PWM noma i-microcontroller efanele
Ukuze usebenzise i-PWM ngempumelelo ukulawula isivinini se-vibration motor kanye namandla okudlidliza, kumele kukhethwe isilawuli se-PWM noma i-microcontroller efanelekile engakhiqiza isignali ye-PWM edingekayo. Isilawuli kufanele sikwazi ukukhiqiza isignali ye-PWM evame kakhulu enomjikelezo womsebenzi olungisekayo. Ngakho-ke singahlangabezana nezidingo ezithile zohlelo lokusebenza.
Ngaphezu kwalokho, kubalulekile ukucabangelainjini encane yokudlidlizaImininingwane kanye nezici zokusebenza lapho kusetshenziswa ukulawulwa kwe-PWM. Izici ezifana nezici ze-voltage, zamanje, ze-mechanical, kanye ne-elekthronikhi zemoto kufanele zicatshangelwe ukuqinisekisa ukusebenza okuphephile nokusebenza kahle.
Imijikelezo yomsebenzi we-PWM
Ngokufigqiwe
I-PWM iyithuluzi elinamandla lokulawula isivinini kanye namandla okudlidliza kwe-aInjini yokudlidliza ye-DCNgokuqonda izimiso zezimpawu ze-PWM nokukhetha isilawuli se-PWM esifanele, ukulawulwa okunembile nokuthembekile kokusebenza kwenjini kungafinyelelwa. Kuwubuchwepheshe obubalulekile ekulawulweni kwenjini nasekudlidlizeni.
Xhumana Nochwepheshe Bakho Abaphambili
Sikusiza ukuthi ugweme izingibe zokuletha ikhwalithi futhi uhloniphe isidingo sakho senjini encane engenamabhulashi, ngesikhathi futhi ngesabelomali.
