I-PWM (Pulse Width Modulation) iyindlela esetshenziswa kabanzi ukulawula isivinini namandla okudlidliza we-DC noma amamotho wokudlidliza. Uma isignali ye-PWM ephezulu isetshenziswa enjinini, i-voltage evamile eshayela injini yileso siginali. Lokhu kuvumela ukulawula okunembile kwejubane lemoto namandla okudlidliza. Kuyithuluzi elibalulekile ezinhlelweni ezahlukahlukene ezihlanganisa amarobhothi, imishini yezimboni, kanye nogesi wabathengi.
Qonda izisekelo zamasiginali we-PWM
Ukusebenzisa i-PWM ukulawula isivinini namandla okudlidliza enjini, kubalulekile ukuqonda izisekelo zamasiginali we-PWM. Isignali ye-PWM iqukethe uchungechunge lwama-pulses, lapho ububanzi be-pulse (okuthiwa umjikelezo womsebenzi) bunquma i-voltage evamile esetshenziswa injini. Ngokulungisa umjikelezo womsebenzi wesignali ye-PWM, i-voltage esebenzayo kanye namanje okulethwa emotweni kungalawulwa, ngaleyo ndlela kulungiswe isivinini namandla okudlidliza wemoto.
Uma usebenzisa i-PWM ku-auhlamvu lwemali vibration motor, imvamisa yesiginali ye-PWM idlala indima ebalulekile ekunqumeni ukusebenza kwenjini. Amafrikhwensi aphezulu e-PWM avumela ukulawula okushelelayo, okunembe kakhudlwana kwejubane lemoto namandla okudlidliza. Ngaphezu kwalokho, imvamisa ye-PWM kufanele ikhethwe ngokucophelela ukugwema noma yimiphi imiphumela engathandeki enjengomsindo ozwakalayo noma ukuzwakala kwemishini emotweni.

Khetha isilawuli esilungile se-PWM noma isilawuli esincane
Ukuze usebenzise ngempumelelo i-PWM ukuze ulawule isivinini semoto yokudlidliza namandla okudlidliza, isilawuli se-PWM esifanelekile noma isilawuli esincane kufanele sikhethwe esingakhiqiza isignali ye-PWM edingekayo. Isilawuli kufanele sikwazi ukukhiqiza isignali ye-PWM yemvamisa ephezulu ngomjikelezo wemisebenzi olungisekayo. Ngakho-ke ingahlangabezana nezidingo ezithile zohlelo lokusebenza.
Ukwengeza, kubalulekile ukucabangelamotor vibration encaneUkucaciswa nezici zokusebenza lapho usebenzisa ukulawula kwe-PWM. Izinto ezifana ne-voltage, zamanje, nezici zikagesi zemoto kufanele zibhekwe ukuze kuqinisekiswe ukusebenza okuphephile nokusebenza kahle.
Imijikelezo yomsebenzi we-PWM
Ngokufigqiwe
I-PWM iyithuluzi elinamandla lokulawula ijubane namandla okudlidliza kwe-aDC vibration motor. Ngokuqonda izimiso zezimpawu ze-PWM nokukhetha isilawuli se-PWM esifanele, ukulawula okunembayo nokuthembekile kokusebenza kwemoto kungafinyelelwa. Kuwubuchwepheshe obubalulekile ekulawuleni izithuthuthu kanye nezinhlelo zokusebenza zokudlidliza.
Xhumana Nochwepheshe Bakho Abaholayo
Sikusiza ukuthi ugweme izingibe zokuletha ikhwalithi futhi wazise isidingo sakho se-micro brushless motor, ngesikhathi nangesabelomali.
