Pfungwa huru yekutanga: Tevedzera musimboti wechiyero cheU/f chisingachinjiPasi pesimba repasi, simba remagineti riri mugedhi remhepo remota rinoenderana zvakananga nevoltage ye stator uye frequencyKugadzikana kwehuwandu hwemagetsi-frequency (U/f) kunosarudza zvakananga kana magnetic flux isingachinji. Mukudzora, voltage nefrequency zvinofanirwa kugadziriswa panguva imwe chete kuti chiyero cheU/f chirambe chisina kuchinja, kudzivirira torque drift inokonzerwa nekuwanda kwemagetsi kana kusakwana. Pamusoro pezvo, kune mota dzisina simba, zvinodikanwa kutsiva kudonha kwemagetsi e stator kudzivirira kukanganiswa kwekudonha kwemagetsi mu low-speed range pa torque accuracy uye kuwedzera kuvimbika kwekushanda kwe low-speed.
Pfungwa Yechipiri Yepfungwa Huru: Kudzora Kwakarurama kweZvikamu Zvemazuva Ano. Nekushandisa dhizaini yekudzora vector, ma currents ematanho matatu e stator anoshandurwa kuita zvikamu zve system ye dq coordinate. Q-axis current inoenderana zvakananga nekuburitsa torqueuye inoda kugadzikana pamutengo wakatarwa kuburikidzakudzora kwe-closed-loop. D-axis current inochengetedza kushamisika nguva dzose kuti ive nechokwadi chekuti magnetic flux inogara yakasimba. Panguva imwe chete, miganhu yemagetsi yakatarwa yakagadzirirwa kubata shanduko dzemutoro unongoerekana waitika uye mamiriro ekutanga, kudzivirira kupiswa kwemidziyo yemagetsi nekuda kwemagetsi anoputika uye kuve nechokwadi chekuti torque inobuda zvakanaka uye isina kuvhunduka.
Pfungwa Yechitatu Yekutanga: Kugadzirisa Kukanganiswa Kunobudirira uye Kugadzirisa Mamiriro Ekushanda. Kuongororwa kwenguva chaiyo kwema parameter akadai sekumhanya, mutoro, uye tembiricha kunoitwa. Kana mutoro ukangoerekana wachinja, voltage uye current ratios zvinogadziriswa nekukurumidza kuti zvitsivire kukanganisa kwe torque. Kune parameter drift inokonzerwa nekuwedzera kwetembiricha, nzira ye dynamic calibration inopihwa kugadzirisa kutsauka mukuramba uye inductance. Pfungwa yekutanga inogadziriswa, uye nzira ye soft-start inotorwa kuderedza torque shock, zvichiita kuti startup ive yakapfava mumamiriro ezvinhu ane mutoro unorema uye kuve nechokwadi chakakwana chekururamisa uye kugadzikana kwe constant torque control.
