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 hanyar yanzu, gabaɗaya tare da direban motar da ya dace, canza ƙarfin fitarwa na direba kuma yana iya sarrafa saurin injin ɗin da ba shi da buroshi, idan babu direba, 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 daidaitawa ta mitar don daidaita saurin motar ba, 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 ƙarfin lantarki, don cimma burin canjin saurin motar dc maras goge. Yana daidaita shi ta hanyar haɓaka haɓakawa. Hanyoyi biyu na sarrafa PWM:
1. An karɓi siginar PWM don sarrafa lokacin tafiyar da transistor. Tsawon lokacin tafiyar da aiki, 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 wutar lantarki don cimma wannan.
Hanyar 3: idan akaramin motar wutagudun kuma zai iya amfani da juriya (ba a ba da shawarar ba, hanya mai sauƙi ce, 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 a har yanzu nemo motar motar dc mara kyau.
Ina fatan sama uku hanyoyindc 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!
