Yadda ake daidaita injinan BLDC da sauri?

1. Tsarin saurin wutar lantarki
Daidaita saurin ƙarfin lantarki ita ce hanya mafi sauƙi ta daidaita gudu, wadda ke sarrafa saurin motar ta hanyar canza ƙarfin wutar lantarki na DC. Lokacin da ƙarfin lantarki ya ƙaru, saurin motar zai ƙaru; akasin haka, lokacin da ƙarfin lantarki ya ragu, saurin motar zai ragu. Wannan hanya ce mai sauƙi kuma mai sauƙin aiwatarwa, amma ga injunan da ke da ƙarfin lantarki mai yawa, tasirin daidaita saurin ƙarfin lantarki ba shi da kyau, saboda ingancin motar zai ragu yayin da ƙarfin lantarki ya ƙaru.

2. Tsarin saurin PWM
Daidaita saurin PWM (Pulse Width Modulation) hanya ce ta gama gari ta daidaita saurin motar, wadda ke sarrafa saurin motar ta hanyar canza zagayowar aikin siginar PWM. Lokacin da zagayowar aikin siginar PWM ta ƙaru, matsakaicin ƙarfin wutar lantarki na motar shi ma zai ƙaru, ta haka ne zai ƙara saurin motar; akasin haka, lokacin da zagayowar aikin siginar PWM ta ragu, saurin motar shi ma zai ragu. Wannan hanyar za ta iya cimma daidaitaccen sarrafa gudu kuma ta dace da injinan DC marasa gogewa masu ƙarfi daban-daban.

3. Tsarin saurin amsawar firikwensin
Motocin DC marasa gogewa galibi suna da na'urori masu auna sigina na Hall ko encoders. Ta hanyar ra'ayoyin firikwensin game da saurin motar da bayanin matsayinta, ana iya cimma ikon sarrafa saurin madauki. Tsarin saurin madauki na rufewa zai iya inganta daidaiton gudu da daidaiton motar, kuma ya dace da lokutan da ake buƙatar saurin gudu mai yawa, kamar kayan aikin injiniya da tsarin sarrafa kansa.

4. Tsarin saurin amsawa na yanzu
Tsarin saurin amsawa na yanzu hanya ce ta daidaita gudu bisa ga wutar lantarki, wadda ke sarrafa saurin motar ta hanyar sa ido kan wutar lantarki. Lokacin da nauyin motar ya ƙaru, wutar ma za ta ƙaru. A wannan lokacin, ana iya kiyaye saurin motar ta hanyar ƙara ƙarfin lantarki ko daidaita zagayowar aiki na siginar PWM. Wannan hanyar ta dace da yanayi inda nauyin motar ke canzawa sosai kuma zai iya cimma ingantaccen aikin amsawa mai ƙarfi.

5. Matsayin filin maganadisu mara firikwensin da kuma daidaita saurinsa
Tsarin saurin sanya filin maganadisu mara firikwensin fasaha ce ta zamani wadda ke amfani da na'urar sarrafa gudu ta lantarki da ke cikin motar don sa ido da kuma sarrafa filin maganadisu na motar a ainihin lokaci don cimma daidaitaccen iko na saurin motar. Wannan hanyar ba ta buƙatar na'urori masu auna sigina na waje, tana sauƙaƙa tsarin motar, tana inganta aminci da kwanciyar hankali, kuma ta dace da yanayi inda girma da nauyin motar suke da yawa.

A aikace-aikace masu amfani, galibi ana haɗa hanyoyin daidaita gudu da yawa don cimma daidaito da daidaiton sarrafa mota. Bugu da ƙari, ana iya zaɓar tsarin daidaita gudu da ya dace bisa ga takamaiman aikace-aikace da buƙatu. Fasahar daidaita gudu ta injinan DC marasa gogewa tana ci gaba da haɓakawa da haɓakawa. A nan gaba, ƙarin sabbin hanyoyin daidaita gudu za su bayyana don biyan buƙatun sarrafa mota a fannoni daban-daban.
