Ingaba kwenzeka njanidc injini engenabhrashiisantya sokulawula? Uninzi luqala ukusebenzisa ukubonisana nabathengi ngemoto engenamabhrashi, ingxaki ngemoto engenamabhrashi ngokubanzi kwezonyango, izixhobo ezizenzekelayo, iirobhothi, kunye neemoto kwicandelo lokusetyenziswa, ukuze kufezekiswe ulawulo olwahlukileyo lokuqhuba, ukulawula isantya sesantya semoto engenamabhrashi kunye nengxaki yokuqhuba engalunganga nengalunganga banemibuzo emininzi,umzi-mveliso weemoto ezingcangcazelayoukwabelana ngolawulo lwesantya semoto engenabhrashi, iindlela ezintathu:
Indlela yokulawula isantya semoto ye-dc engenabhrashi
Indlela yoku-1: sebenzisa i-voltage ukulawula isantya, i-torque ilawulwa kakhulu yi-current, ngokubanzi nge-motor driver ehambelanayo, ukutshintsha i-output voltage yomqhubi kunokulawula isantya se-brushless motor, ukuba akukho mqhubi, ufuna ukulawula i-motor, kufuneka ubone amandla kunye nomsinga osebenzayo we-motor.
Indlela yesi-2: Ulawulo lwesantya se-PWM, umgaqo wolawulo lwesantya se-PWM wemoto ye-dc kunye nomgaqo wolawulo lwesantya semoto ye-ac wahlukile, asikuko ngokuguqulwa kwesantya semoto ngendlela ye-frequency modulation, kodwa ngokulungelelanisa indlela yokuqhuba i-voltage pulse width, kunye nokusebenzisana nezinye izinto zokugcina amandla ezifanelekileyo kwisekethe, utshintsho kwi-armature voltage amplitude, ukuze kufezekiswe injongo yokutshintsha kwesantya semoto ye-dc engenabhrashi. Ilawulwa yi-amplitude modulation. Kukho iindlela ezimbini zolawulo lwe-PWM:
1. Isignali ye-PWM iyasetyenziswa ukulawula ixesha lokuqhuba kwe-transistor. Okukhona ixesha lokuqhuba lide, kokukhona ixesha lokusebenza lide, kwaye isantya semoto siya kuba phezulu.
2. Isignali yolawulo lwe-PWM isetyenziselwa ukulawula ixesha lokuvala kwe-triode, kwaye i-voltage yolawulo iyatshintshwa ukuze kufezekiswe oku.
Indlela yesi-3: ukuba yi-injini yamandla amancinciIsantya singasebenzisa nokumelana (akukhuthazwa, indlela ilula kakhulu, i-potentiometer can, yile ndlela kuphela enokunciphisa ukusebenza kakuhle, ngoko ke ayikhuthazi), isantya sokulawula amandla aphezulu semoto asinakwamkela ukumelana, kuba ifuna amandla aphezulu okumelana okuncinci (ukumelana nokusebenza kwemoto kuncinci kakhulu), ukumelana kubi ukufumana kwaye ukusebenza kakuhle kwesisombululo kuphantsi kakhulu, kungcono ukufumana ii-dc motor drives ezingenamabhrashi.
Ndiyathemba ukuba ezi ndlela zintathu zingasentlaimoto engenabhrashi ye-dcUlawulo lwesantya sokulawula lunokukunika uncedo kunye nenkuthazo.
Oku kungasentla malunga nokulawulwa kwesantya semoto ye-dc engenamabhulashi kwezi ndlela zintathu, ndiyathemba ukuba unokufumana uncedo; Singabantu abancinciumzi-mveliso weemoto zokungcangcazela, ezi mveliso zezi:imoto yokungcangcazela ethe tye,imoto yokungcangcazela ye-iphone 6s,imoto yokungcangcazela ye-iphone 7;Ndiyathemba ukuba ungaqhagamshelana nathi!
