Ingaba kwenzeka njanidc i-brushless motorUkulawula isantya? Abaninzi baqala ukusebenzisa i-brushless motor yokubonisana nomthengi, ingxaki nge-brushless motor ngokubanzi kwezonyango, izixhobo ezizenzekelayo, iirobhothi, kunye neemoto kwintsimi yesicelo, ukuze baqonde ulawulo oluhlukeneyo lokuqhuba, ukulawula isantya se-brushless dc motor. isantya kunye positive & negative drive ingxaki banemibuzo emininzi, iumzi-mveliso wemoto oshukumayoukwabelana ngolawulo lwesantya semoto yebrushless iindlela ezintathu:
Indlela yokulawula isantya se-brushless dc motor
Indlela yoku-1: sebenzisa i-voltage ukulawula isantya, i-torque ilawulwa ikakhulu ngoku, ngokubanzi kunye nomqhubi wemoto ohambelanayo, ukutshintsha i-voltage ephumayo yomqhubi unokulawula isantya semoto ye-brushless, ukuba akukho mqhubi, ufuna lawula injini, kufuneka ubone amandla kunye nokusebenza ngoku kwemoto.
Indlela yesi-2: Ulawulo lwesantya se-PWM, umgaqo wolawulo lwesantya se-PWM we-dc motor kunye ne-ac motor umgaqo wokulawula isantya sahlukile, ayisiyiyo indlela yokumodareyitha rhoqo ukulungelelanisa isantya semoto, kodwa ngokulungelelanisa indlela yokuqhuba i-voltage pulse ububanzi, kunye nokusebenzisana namanye amacandelo ahambelanayo okugcina amandla kwisekethe, utshintsho kwi-armature voltage amplitude, ukuze kuphunyezwe injongo ye-brushless dc motor change change.It's modulated by amplitude modulation.Kukho iindlela ezimbini zolawulo lwePWM:
1. Isignali ye-PWM yamkelwe ukulawula ixesha lokuqhuba i-transistor.Ixesha elide lokuqhuba, ixesha lomsebenzi liya kuba lide, kwaye isantya esiphezulu semoto siya kuba.
2. Isignali yokulawula i-PWM isetyenziselwa ukulawula i-triode kwi-off-off time, kwaye i-voltage yokulawula iyatshintshwa ukufezekisa oku.
Indlela yesi-3: ukuba iinjini yamandla amancinciIsantya sinokusebenzisa ukuchasana (akukhuthazwa, indlela ilula kakhulu, uchungechunge lwe-potentiometer inako, le ndlela kuphela inokunciphisa ukusebenza kakuhle, ngoko ayikhuthazi), isantya esiphezulu sokulawula amandla emoto asikwazi ukufumana ukuxhathisa, kuba ifuna amandla aphezulu okuchasana okuncinci (ukumelana nokusebenza kweemoto kuncinci kakhulu), ukuxhathisa kubi ukufunyanwa kunye nesisombululo esisebenzayo siphantsi kakhulu, kungcono ukuba ufumane i-brushless dc motor drives.
Ndiyathemba ukuba ezi ndlela zintathu zingasentla zedc brushless motorulawulo lwesantya solawulo lungakunika uncedo kunye nenkuthazo.
Okungasentla kumalunga nolawulo lwesantya semoto yebrushless dc yeendlela ezintathu, ndiyathemba ukuba unoncedo oluthile;i-vibration motor factory, iimveliso zezi:umgca wokungcangcazela kwemoto,iphone 6s vibration motor,iphone 7 vibration motor; Ndiyathemba ukuba ungaqhagamshelana nathi!
