Hanyar sarrafa saurin injin dc maras goge
Hanyar 1: Yi amfani da wutar lantarki don sarrafa saurin, ƙarfin wutar lantarki galibi ana sarrafa shi ta halin yanzu, gabaɗaya tare da direban motar da ya dace, canza ƙarfin fitarwa na direban kuma yana iya sarrafa saurin injin ɗin da ba shi da buroshi, idan babu direba, kuna so. sarrafa motar, buƙatar ganin iko da aiki na yanzu na motar.
Hanyar 2: Kula da saurin PWM, ka'idodin sarrafa saurin PWM na motar dc da ka'idodin sarrafa saurin motsi ya bambanta, ba ta hanyar daidaita saurin mitar ba don daidaita saurin motar, amma ta hanyar daidaita hanyar tuki bugun bugun bugun jini, da kuma yin aiki tare da wasu daidaitattun abubuwan ajiyar makamashi a cikin kewaye, canje-canje zuwa girman ƙarfin lantarki na armature, ta yadda za a cimma burin canza saurin motar dc maras goge.An daidaita shi ta hanyar daidaitawa na amplitude. Akwai hanyoyi guda biyu na sarrafa PWM:
1. An karɓi siginar PWM don sarrafa lokacin tafiyar da transistor.Tsawon lokacin gudanarwa shine, tsawon lokacin aikin zai kasance, kuma mafi girman saurin motar zai kasance.
2. Ana amfani da siginar sarrafawa na PWM don sarrafa lokacin kashewa na triode, kuma ana canza ƙarfin wutar lantarki don cimma wannan.
Hanyar 3: idan akaramin motar wutagudun kuma zai iya amfani da juriya (ba a ba da shawarar ba, hanyar tana da sauƙi, jerin potentiometer iya, kawai wannan hanya zai iya rage yadda ya dace, sabili da haka ba ya ba da shawara), babban ƙarfin iko na motar ba zai iya ɗaukar juriya ba, saboda yana buƙatar babban ƙarfin ƙananan ƙarfin juriya (juriya na aiki na motar yana da ƙananan ƙananan), juriya yana da kyau don ganowa kuma ingancin maganin ya yi ƙasa da ƙasa, yana da kyau don har yanzu nemo motar motar dc mara kyau.
Ina fatan sama uku hanyoyin nadc babur baburƘa'idar saurin sarrafawa na iya ba ku wasu taimako da wahayi.
Abin da ke sama shine game da ka'idojin saurin motar dc mara kyau na hanyoyin uku, Ina fata kuna da taimako; Mu micro negirgiza motor factory, samfuran sune:Motar girgiza kai tsaye, iphone 6s vibration motor, iphone 7 vibration motor; Fata za ku iya tuntuɓar mu!
