Kanjanidc injini engenamabhulashiisivinini sokulawula? Abaningi baqala ukusebenzisa ukubonisana namakhasimende nge-brushless motor, inkinga nge-brushless motor kabanzi kwezokwelapha, imishini yokuzenzakalela, amarobhothi, kanye nezimoto emkhakheni wokusetshenziswa, ukuze kufezwe ukulawula okuhlukile kokushayela, ukulawula isivinini se-brushless dc motor kanye nenkinga yokushayela okuhle nokubi banemibuzo eminingi,ifektri yezimoto ezidlidlizayoukwabelana ngokulawula isivinini senjini engenamabhulashi izindlela ezintathu:
Indlela yokulawula isivinini semoto ye-dc engenamabhulashi
Indlela 1: sebenzisa i-voltage ukulawula ijubane, i-torque ilawulwa kakhulu yi-current, ngokuvamile nge-driver yemoto ehambisanayo, ukushintsha i-voltage yokuphuma komshayeli kungalawula nejubane le-motor engenamabhulashi, uma kungekho mshayeli, ufuna ukulawula imoto, udinga ukubona amandla kanye nogesi osebenzayo wemoto.
Indlela 2: Ukulawulwa kwejubane le-PWM, isimiso sokulawula ijubane le-PWM semoto ye-dc kanye nesimiso sokulawula ijubane lemoto ye-ac kuhlukile, akuyona indlela yokushintshashintsha ijubane lemoto ngokushintshashintsha imvamisa, kodwa ngokushintsha indlela yokushayela i-voltage ububanzi be-pulse, kanye nokubambisana nezinye izingxenye zokugcina amandla ezihambisanayo kusekethe, izinguquko ku-amplitude ye-armature voltage, ukuze kufezwe inhloso yokushintsha ijubane lemoto ye-dc engenamabhulashi. Kuguqulwa ngokuguquguquka kwe-amplitude. Kunezindlela ezimbili zokulawula i-PWM:
1. Isignali ye-PWM iyasetshenziswa ukulawula isikhathi sokuqhuba kwe-transistor. Uma isikhathi sokuqhuba side, isikhathi somsebenzi sizoba side, futhi ijubane lemoto lizoba phezulu.
2. Isignali yokulawula ye-PWM isetshenziselwa ukulawula isikhathi sokuvala kwe-triode, futhi i-voltage yokulawula iyashintshwa ukuze kufezwe lokhu.
Indlela 3: uma kungeyonainjini yamandla amancaneisivinini singasebenzisa nokumelana (akunconywa, indlela ilula kakhulu, uchungechunge lwe-potentiometer can, ngale ndlela kuphela enganciphisa ukusebenza kahle, ngakho-ke ayikukhuthazi), isivinini sokulawula amandla aphezulu semoto asikwazi ukwamukela ukumelana, ngoba sidinga ukumelana okuncane kwamandla aphezulu (ukumelana nokusebenza kwemoto kuncane kakhulu), ukumelana kubi ukuthola futhi ukusebenza kahle kwesixazululo kuphansi kakhulu, kungcono ukuthola ama-drive e-dc motor angenamabhulashi.
Ngiyethemba ukuthi izindlela ezintathu ezingenhlaimoto engenamabhulashi ye-dcUkulawulwa kwesivinini sokulawula kungakunikeza usizo kanye nogqozi.
Lokhu okungenhla kumayelana nokulawulwa kwesivinini semoto ye-dc engenamabhulashi kulezi zindlela ezintathu, ngithemba ukuthi uzothola usizo; Siyi-microifektri yezimoto zokudlidliza, imikhiqizo yile:imoto yokudlidliza eqondile,injini yokudlidliza ye-iphone 6s,injini yokudlidliza ye-iphone 7; Ngiyethemba ukuthi ungasithinta!
