Motar DC mara nauyi(BLDC) babban inganci ne, ƙaramar hayaniya, motar rayuwa mai tsawo wacce ake amfani da ita a fagage daban-daban, irin su sarrafa kansa na masana'antu, kayan aikin wuta, motocin lantarki, da dai sauransu. Tsarin saurin aiki muhimmin aiki ne na injin DC maras gogewa. sarrafawa. Za a gabatar da hanyoyin ƙa'idodin saurin mota marasa goga da yawa na kowa a ƙasa.
1. Tsarin saurin wutar lantarki
Tsarin saurin wutar lantarki shine hanya mafi sauƙi mafi sauƙi na daidaita saurin motsi, wanda ke sarrafa saurin motar ta hanyar canza ƙarfin wutar lantarki na DC. Lokacin da ƙarfin lantarki ya ƙaru, saurin motar kuma zai ƙaru; akasin haka, lokacin da ƙarfin lantarki ya ragu, saurin motar kuma zai ragu. Wannan hanya mai sauƙi ne kuma mai sauƙi don aiwatarwa, amma ga manyan motoci masu ƙarfi, tasirin ka'idojin saurin wutar lantarki ba shi da kyau, saboda ingancin motar zai ragu yayin da ƙarfin lantarki ya karu.
2. Tsarin saurin PWM
PWM (Pulse Width Modulation) Tsarin saurin gudu hanya ce ta gama gari ta ƙayyadaddun saurin motsi, wanda ke sarrafa saurin motar ta hanyar canza yanayin aikin siginar PWM. Lokacin da sake zagayowar aikin siginar PWM ya ƙaru, matsakaicin ƙarfin lantarki na motar shima zai ƙaru, ta haka zai ƙara saurin motar; akasin haka, lokacin da aikin sake zagayowar siginar PWM ya ragu, saurin motar kuma zai ragu. Wannan hanyar za ta iya cimma daidaitaccen sarrafa saurin gudu kuma ta dace da injinan DC marasa goga na iko iri-iri.
3. Ƙa'idar saurin amsawa na Sensor
Motocin DC marasa gogewa yawanci ana sanye su da na'urori masu auna firikwensin Hall ko na'urorin haɗi. Ta hanyar ra'ayin firikwensin na saurin motar da bayanin matsayi, ana iya samun sarrafa saurin rufaffiyar madauki. Tsarin saurin rufe-madauki na iya inganta saurin kwanciyar hankali da daidaiton motar, kuma ya dace da lokatai tare da buƙatun saurin gudu, kamar kayan aikin injina da tsarin sarrafa kansa.
4. Tsarin saurin amsawa na yanzu
Ka'idojin saurin amsawa na yanzu hanya ce ta ƙa'ida ta sauri dangane da halin yanzu na motsi, wanda ke sarrafa saurin motar ta hanyar sa ido kan abin da ke faruwa a halin yanzu. Lokacin da nauyin motar ya karu, na yanzu kuma zai karu. A wannan lokacin, ana iya kiyaye tsayayyen saurin motar ta hanyar ƙara ƙarfin lantarki ko daidaita yanayin aikin siginar PWM. Wannan hanya ta dace da yanayi inda nauyin motar ke canzawa sosai kuma zai iya samun kyakkyawan aikin mayar da martani.
5. Matsakaicin filin maganadisu mara hankali da tsarin saurin gudu
Matsakaicin saurin yanayin filin maganadisu mara fahimta fasaha ce ta ci gaba mai sarrafa saurin sauri wacce ke amfani da mai sarrafa lantarki a cikin motar don saka idanu da sarrafa filin maganadisu na injin a ainihin lokacin don cimma daidaitaccen sarrafa saurin motar. Wannan hanyar ba ta buƙatar na'urori masu auna firikwensin waje, sauƙaƙe tsarin motar, inganta aminci da kwanciyar hankali, kuma ya dace da yanayin da girma da nauyin motar ke da yawa.
A aikace-aikace masu amfani, hanyoyin daidaita saurin gudu yawanci ana haɗa su don cimma ingantacciyar kulawar mota. Bugu da ƙari, za a iya zaɓar tsarin daidaita saurin gudu bisa ga takamaiman aikace-aikace da buƙatu. Fasahar sarrafa saurin injin injin DC maras goge yana haɓaka da haɓaka koyaushe. A nan gaba, ƙarin sabbin hanyoyin daidaita saurin gudu za su bayyana don biyan buƙatun sarrafa motoci a fagage daban-daban.
