Mibairo yakaipa yemotor ichitiza kubva kune yakatemerwa voltage

Inopisa ine ruzivo tekinoroji 36V 48V Hub Motors ine Factory Wholesale Mutengo

Chero chigadzirwa chemagetsi, kusanganisira zvigadzirwa zvemotokari, chokwadika, chataura nezve rated voltage yekushanda zvakajairika, uye chero kutsauka kwemagetsi kunokonzeresa mhedzisiro yekushanda kwakajairika kwemidziyo yemagetsi.
Kune michina yakakwira-yekupedzisira, iyo inodiwa yekudzivirira michina inogamuchirwa.Kana magetsi emagetsi asina kujairika, magetsi anogurwa kudzivirira.Nokuda kwezviridzwa zvakanyatsojeka, iyo inogara-voltage magetsi inoshandiswa kugadzirisa.Nekudaro, mukana wezvigadzirwa zvemotokari, kunyanya zvigadzirwa zvemaindasitiri emotokari, kushandisa zvinogara-voltage zvishandiso idiki zvakanyanya, uye kune akawanda kesi ekudzivirira-kudzima magetsi.
Kune imwe-phase motors, kune mamiriro maviri chete: yakakwira voltage uye yakaderera voltage, nepo kune matatu-phase motors, pane dambudziko revoltage balance.Iyo yakananga pesvedzero yeaya matatu voltage deviations kuwedzera ikozvino kana kusaenzana kwazvino.
Zvinoenderana nehunyanzvi mamiriro emota, kutsauka kweiyo yakatemerwa voltage yemotor hakugone kudarika 10%, uye torque yemota yakanyatso kuenzana neskweya yeterminal voltage yemota.Kana iyo voltage yakawandisa, iyo mota yepakati ichave iri mumamiriro ekuzara kwemagineti, uye kuwedzera kweiyo stator ikozvino kunotungamira mukupisa kwakanyanya kwemhepo, kunyangwe dambudziko remhando yekupisa kupisa.Nekudaro, kana iri low voltage, panogona kunge paine mamwe matambudziko mukutanga kwemota, kunyanya kune mota inomhanya pamutoro.Kuti isangane nezvinodiwa zvemota inomhanya pamutoro, ikozvino inofanirwawo kuwedzerwa, uye mhedzisiro yekuwedzera ikozvino ichave yekupisa kana kutsva kwemhepo, kunyanya kune iyo yakareba-yakaderera-voltage oparesheni, izvo zvakatonyanya kuoma.
Unbalanced voltage yetatu-phase mota idambudziko rekupa magetsi.Kana iyo voltage isingaenzaniswi, inozotungamira kune isina kuenzana mota ikozvino.Iyo yakaipa sequence chikamu cheiyo isina kuenzana voltage inoburitsa magineti mumhepo gap remota rakatarisana nerotor kutenderera.Iyo diki yakaipa sequence chikamu chevoltage inogona kuita kuti ikozvino kuyerera kuburikidza nemhepo inovhuvhuta yakakura kupfuura ikozvino kana voltage yakaenzana.Kuwanda kwezvino kuyerera kuburikidza nerotor bar kunenge kaviri iyo yakatemerwa frequency, saka ikozvino kudzvanya mhedzisiro murotor bar inoita kurasikirwa kwakawedzera kukosha kweiyo rotor mhepo yakakura kupfuura iyo ye stator winding.Kuwedzera kwekushisa kwe stator winding yakakwirira kudarika iyo stator inomhanya pasi pemagetsi akaenzana.
Kana iyo voltage isingaenzaniswi, iyo yakakiyiwa-rotor torque, shoma torque uye yakakura torque yemota zvese zvinodzikira.Kana iyo voltage kusaenzana kwakakomba, mota haishande zvakajairika.
Apo motokari iri kushanda pamutoro wakakwana pasi pemagetsi asina kuenzana, nokuti chiyero chekutsvedza chinowedzera nekuwedzera kwekuwedzera kurasikirwa kwe rotor, kukurumidza kuchaderera zvishoma panguva ino.Nekuwedzera kwemagetsi (ikozvino) kusaenzana, ruzha uye kudengenyeka kwemotokari kunogona kuwedzera.Vibration inogona kukuvadza mota kana iyo yese drive system.
Kuti unyatsoona zvinokonzeresa kusaenzana kwemotor voltage, zvinogona kuitwa kuburikidza nekuona magetsi emagetsi kana shanduko iripo.Mazhinji maturusi akashongedzerwa nemagetsi ekutarisa zviridzwa, izvo zvinogona kuongororwa kuburikidza nekuenzanisa data.Kune avo vasina midziyo yekutarisa, kugaroonekwa kana kuyerwa kwazvino kunofanirwa kutorwa.Kune mota dzinogona kutenderera kumberi nekumashure, unogona kushandura zvisingaite mitsara yemagetsi maviri-chikamu uye kuona shanduko yezvino, uchiongorora zvisina kunanga chiyero chevoltage.Mushure mekubvisa dambudziko remagetsi asina kuenzana, zvinogona kusanganisira matambudziko emhando sekutendeuka-kutendeuka uye chikamu-kune-chikamu.
