I-algorithm ye- I-AC brushless motor kanye ne-AC brushed motor

• Ukulawulwa kwe-scalar

Ukulawulwa kwe-scalar (noma ukulawula kwe-V/Hz) kuyindlela elula yokulawula isivinini semoto yokufundisa
Imodeli yesimo sokuzinza yemoto yomyalo isetshenziselwa ikakhulukazi ukuthola ubuchwepheshe, ngakho-ke ukusebenza kwesikhashana akunakwenzeka.Isistimu ayinayo i-loop yamanje.Ukulawula imoto, ukunikezwa kwamandla kwesigaba sesithathu kuyahlukahluka kuphela ku-amplitude kanye nemvamisa.

• Isilawuli se-Vector noma isilawuli esigxile enkambu

I-torque esemotweni iyahlukahluka ngomsebenzi we-stator kanye nezindawo kazibuthe ze-rotor futhi ifinyelela esiqongweni sayo lapho izindawo ezimbili zikazibuthe zine-orthogonal enye kwenye.Ekulawulweni okusekelwe ku-scalar, i-Engeli phakathi kwezizibuthe ezimbili zishintsha kakhulu.
Ukulawulwa kwe-Vector kuzama ukwenza kabusha i-orthogonality kumamotho e-AC. Ukuze kulawulwe i-torque, okwamanje okukhiqizwa ku-flux kazibuthe kukhiqizwa ngokulandelanayo ukuze kuzuzwe ukuphendula komshini we-DC.
Isilawuli ivekhtha senjini yokulawula ye-AC siyefana nesenjini eyodwa ye-DC ejabulile.Kunjini ye-DC, amandla kazibuthe Φ F akhiqizwe yi-excitation yamanje IF i-orthogonal ku-armature magnetic flux tangent A ekhiqizwa i-armature current. IA.Lezi zindawo kazibuthe zihlukaniswe futhi zizinzile komunye nomunye.Ngakho, lapho i-armature current ilawulwa ukuze kulawulwe i-torque, amandla kazibuthe ahlala engathinteki futhi impendulo yesikhashana esheshayo ifinyelelwa.
Isilawuli esigxile emkhakheni (i-FOC) senjini ye-AC enezigaba ezintathu sihlanganisa ukusebenza okulingisa okwenjini ye-DC.Zonke izinto eziguquguqukayo ezilawulwayo ziguqulelwa ngokwezibalo zibe yi-DC esikhundleni se-AC.Ithagethi yayo ilawulwa ngokuzimele yi-torque nokuguquguquka.

• Kunezindlela ezimbili zokulawula okugxile emkhakheni (i-FOC) :

I-FOC eqondile: I-Angle ye-Rotor flux ibalwa ngokuqondile yisibukeli se-flux
I-FOC Engaqondile: I-Rotor flux Angle itholakala ngokungaqondile ngokulinganisa noma ukulinganisa isivinini se-Rotor nokushelela.
Ukulawulwa kwe-Vector kudinga ukuqonda ukuma kwe-rotor flux futhi kungabalwa kusetshenziswa ama-algorithms athuthukisiwe asekelwe olwazini lwe-terminal current kanye ne-voltage (kusetshenziswa amamodeli aguquguqukayo we-AC induction motors). Nokho, ngokombono wokuqalisa, isidingo izinsiza zekhompyutha zibalulekile.

I-algorithm yokulawula i-vector ingasetshenziswa ngezindlela ezihlukene.Amasu e-Feedforward, ukulinganisa kwemodeli, namasu okulawula okuguquguqukayo angasetshenziswa ukuze kuthuthukiswe impendulo nokuzinza.

I-JIUYUAN inonjiniyela abangochwepheshe abanolwazi olungaphezu kweminyaka engama-20i-brushless dc motor encane,i-rotor yangaphandle brushless dc motor,i-rotor yangaphakathi brushless dc motor,outrunner brushless DC motor, brushless dc motor with controller or drive, AC brushless motor kanye AC brushed motor njll.Xhumana nathiukuze uthole imininingwane.
