Brushless DC mota(BLDC) ndeyepamusoro-soro, yakaderera-ruzha, yehupenyu hurefu mota inoshandiswa zvakanyanya munzvimbo dzakasiyana siyana, senge maindasitiri otomatiki, maturusi emagetsi, mota dzemagetsi, etc. Speed regulation ibasa rakakosha re brushless DC mota. control. Dzakawanda dzakajairwa brushless DC mota yekumhanyisa kudzora nzira dzichaunzwa pazasi.
1. Voltage speed regulation
Voltage speed regulation ndiyo yakareruka yekumhanya kudzora nzira, iyo inodzora kumhanya kwemota nekushandura voltage yeDC magetsi. Kana iyo voltage ichiwedzera, kumhanya kwemota kuchawedzerawo; ukuwo, kana voltage ichidzikira, kumhanya kwemota kunodererawo. Iyi nzira iri nyore uye iri nyore kuita, asi kune yakakwirira-simba motors, mhedzisiro yevoltage yekumhanyisa regulation haina kunaka, nekuti kushanda kwemota kunodzikira sezvo voltage ichiwedzera.
2. PWM speed regulation
PWM (Pulse Width Modulation) yekumhanyisa kudzora inzira yakajairika yekumhanyisa mota regulation, iyo inodzora kumhanya kwemota nekushandura kutenderera kwebasa rechiratidzo chePWM. Kana basa rekutenderera kwePWM chiratidzo richiwedzera, avhareji voltage yemota inowedzerawo, nekudaro ichiwedzera kumhanya kwemota; ukuwo, kana kutenderera kwebasa reiyo PWM chiratidzo kuchiderera, kumhanya kwemota kunodererawo. Iyi nzira inogona kuwana chaiyo yekumhanyisa kudzora uye inokodzera brushless DC mota dzemasimba akasiyana.
3. Sensor mhinduro yekumhanyisa mutemo
Brushless DC mota dzinowanzo shongedzerwa neHoro sensors kana encoder. Kuburikidza nemhinduro ye sensor yekumhanyisa mota uye ruzivo rwechinzvimbo, yakavharwa-loop yekumhanyisa kudzora inogona kuwanikwa. Yakavharwa-loop yekumhanyisa regulation inogona kuvandudza kugadzikana uye kurongeka kwemota, uye inokodzera zviitiko zvine kumhanya kwakanyanya zvinodiwa, senge mishini yemagetsi uye otomatiki masisitimu.
4. Ikozvino mhinduro yekumhanyisa mutemo
Yazvino mhinduro yekumhanyisa regulation inzira yekumhanyisa yekudzora yakavakirwa pane mota ikozvino, iyo inodzora kumhanya kwemota nekutarisa mota ikozvino. Kana mutoro wemotokari unowedzera, ikozvino inowedzerawo. Panguva ino, kumhanya kwakagadzikana kwemota kunogona kuchengetedzwa nekuwedzera voltage kana kugadzirisa basa rekutenderera kwePWM chiratidzo. Iyi nzira inokodzera mamiriro apo mota inotakura inochinja zvakanyanya uye inogona kuwana zvirinani simba rekupindura kuita.
5. Sensorless magnetic field positioning uye speed regulation
Sensorless magnetic field positioning speed regulation ndeye advanced speed regulation tekinoroji inoshandisa yemagetsi controller mukati memotor kutarisa uye kudzora iyo mota yemagineti munguva chaiyo kuti uwane kunyatso kudzora kwemota kumhanya. Iyi nzira haidi ma sensors ekunze, inorerutsa chimiro chemota, inovandudza kuvimbika uye kugadzikana, uye inokodzera mamiriro apo vhoriyamu uye uremu hwemotokari zvakakwirira.
Mumashandisirwo anoshanda, nzira dzakawanda dzekumhanya dzekudzora dzinowanzo kusanganiswa kuti dzive dzakanyatsojeka uye dzakagadzikana kudzora mota. Uye zvakare, iyo yakakodzera yekumhanyisa regulation chirongwa inogona kusarudzwa zvinoenderana nechaiyo mashandisirwo uye zvinodiwa. Iyo yekumhanyisa mutemo tekinoroji yebrushless DC motors iri kugara ichigadzira nekuvandudza. Mune ramangwana, mamwe maitiro ekugadzirisa ekumhanya anozoonekwa kuti anosangana nezvinodiwa zvekutonga mota munzvimbo dzakasiyana.
