Chero chigadzirwa chemagetsi, kusanganisira zvigadzirwa zvemotokari, hongu, zvinotaridza chiyero chakayerwa chekushanda kwayo.Chero kutsauswa kwemagetsi kunokonzeresa mhedzisiro yekushanda kwakajairwa kwechinhu chemagetsi.
Kune michina yakakwira-yekupedzisira, zvinodiwa zvekudzivirira zvinoshandiswa.Kana magetsi emagetsi asina kujairika, magetsi anogurwa kudzivirira.Kune zviridzwa zvakanyatsojeka, nguva dzose magetsi emagetsi anoshandiswa kugadzirisa.Zvigadzirwa zvemotokari, kunyanya Zvezvigadzirwa zvemotokari dzemaindasitiri, mukana wekushandisa chigadziro chemagetsi idiki zvakanyanya, uye kune akawanda kesi ekudzivirira-kudzima magetsi.
Kune imwe-chikamu mota, kune maviri chete mamiriro eiyo yakakwira voltage uye yakaderera voltage, nepo kune matatu-chikamu mota, kune zvakare dambudziko remagetsi.Kuratidzwa kwakananga kwekupesvedzera kweaya matatu voltage deviations kuwedzera kwazvino kana kusaenzana kwazvino.
Mamiriro ehunyanzvi emota anotaridza kuti kutsauka kwepamusoro nepasi kweiyo yakayerwa voltage yemotor haigone kudarika 10%, uye torque yemotor inoenzanirana ne square yemotor terminal voltage.Kana iyo voltage yakawandisa, iyo simbi yepakati yemota ichave iri mumamiriro ekuzara kwemagineti, uye iyo stator ikozvino inowedzera.Ichatungamira mukupisa kwakakomba kwemhepo, uye kunyangwe dambudziko remhando yekupisa kwemhepo;uye nezvenyaya yemagetsi yakaderera, imwe ndeyekuti panogona kunge paine matambudziko nekutanga kwemota, kunyanya kune mota inomhanya pasi pemutoro, kuitira kuti isangane nemutoro unomhanya wemota, Iyo yazvino inofanirawo kuwedzerwa, uye iyo mhedzisiro yekuwedzera ikozvino zvakare kupisa uye kunyange kutsva kwema windings, kunyanya kwenguva refu-yakaderera-voltage oparesheni, dambudziko rinonyanya kuoma.
Unbalanced voltage yetatu-phase mota idambudziko rekupa magetsi.Kana iyo voltage isingaenzaniswi, inozotungamira kune isina kuenzana mota ikozvino.Iyo yakaipa sequence chikamu cheiyo unbalanced voltage inogadzira magineti mumhepo gap yemota inopikisa kutendeuka kwe rotor.Chinhu chidiki chisina kunaka chinoteedzana mumagetsi chinogona kukonzera kuti ikozvino kuburikidza nemhepo inotenderedza ive yakakura kupfuura iyo voltage yakaenzana.Iyo yakawanda yezvino inoyerera mumabheji e rotor inenge yakapetwa kaviri iyo yakatemerwa frequency, saka ikozvino kusvina mhedzisiro mumarotor bars inoita kurasikirwa kwekuwedzera kweiyo rotor windings yakakura kupfuura iyo ye stator windings.Kuwedzera kwekushisa kwe stator winding kwakakwirira kudarika iyo kana ichishanda pamagetsi akaenzana.
Kana iyo voltage isingaenzaniswi, torque yekutandarira, diki torque uye yakanyanya torque yemota zvese zvinodzikiswa.Kana iyo voltage kusaenzana kwakakomba, mota haishande nemazvo.
Apo motokari inomhanya pamutoro wakakwana pasi pemhepo isina kukwana, sezvo slip inowedzera nekuwedzera kwekurasikirwa kwe rotor, kukurumidza kuchaderera zvishoma panguva ino.Sezvo voltage (ikozvino) kusaenzana kunowedzera, ruzha uye kudengenyeka kwemotokari kunogona kuwedzera.Vibration inogona kukuvadza mota kana iyo yese drive system.
Kuti unyatsoona chikonzero cheiyo isina kuenzana mota voltage, inogona kuitwa nenzira yekuonekwa kwemagetsi emagetsi kana kusiyanisa ikozvino.Midziyo mizhinji ine mudziyo wekutarisa voltage, iyo inogona kuongororwa nekuenzanisa data.Kune iyo kesi kana pasina chigadziro chekutarisa, kugaroonekwa kana kuyerwa kwazvino kunofanirwa kushandiswa.Panyaya yekukwevera michina, tambo yemagetsi maviri-chikamu inogona kuchinjika zvisina tsarukano, shanduko iripo inogona kucherechedzwa, uye chiyero chemagetsi chinogona kuongororwa zvisina kunanga.
