Musimboti wekushanda weiyo matatu-chinhu asynchronous mota inofanirwa kunge iri:
Kana symmetrical matatu-term alternating current ichipfuudzwa mutatu-term stator winding, inotenderera magnetic field inogadzirwa iyo inotenderera newachi nechepakati penzvimbo yemukati yedenderedzwa ye stator uye rotor pa synchronous speed n1.Sezvo iyo inotenderera magineti inotenderera pa n1 kumhanya, iyo rotor conductor yakamira pakutanga, saka rotor conductor inocheka stator inotenderera magineti uye inogadzira iyo induced electromotive simba (kutungamirwa kweiyo induced electromotive simba inotemwa neruoko rwerudyi. kutonga).Sezvo magumo ose emuitisi ari mapfupi-akatenderedzwa nemhete-pfupi, pasi pechiito chesimba re electromotive induced, ikozvino induced inogadzirwa mu rotor conductor iyo inonyanya kuenderana nekutungamira kweiyo induced electromotive force.Ikozvino-inotakura conductors ye rotor inoshandiswa nemagetsi emagetsi mu stator's magnetic field (kutungamirirwa kwesimba kunotsanangurwa nekutonga kuruboshwe).Simba remagetsi rinogadzira electromagnetic torque pane rotor shaft, ichityaira rotor kuti itenderere negwara remagineti inotenderera.
Kuburikidza nekuongorora kuri pamusoro, zvinogona kugumiswa kuti musimboti wekushanda wemotor ndewekuti: kana matatu stator windings yemota (imwe neimwe ine chikamu musiyano we120 madhigirii mumakona emagetsi) inopihwa matatu anochinjana mafungu, inotenderera magineti. ichagadzirwa.Mhepo yakakonzerwa inogadzirwa mumhepo (iyo rotor winding inzira yakavharwa).Ikozvino-inotakura rotor conductor inoburitsa simba remagetsi pasi pechiito cheiyo stator inotenderera magineti, nekudaro ichigadzira iyo electromagnetic torque pane mota shaft, ichityaira mota kutenderera, uye kutenderera kwemota kunoenderana neinotenderera magineti.Same direction.
Zvikonzero: 1. Kana imwe kana maviri chikamu windings yemotokari ichipiswa kunze (kana kupisa), inowanzokonzerwa nekurasikirwa kwechikamu kushanda.Hapazovi nekuongorora kwakadzama kwedzidziso pano, kungotsanangura muchidimbu.Kana mota ikarasikirwa nechikamu chero chikonzero, kunyangwe mota ichigona kuramba ichimhanya, kumhanya kunodonha uye kutsvedza kunokura.Iwo B uye C nhanho inova yakatevedzana hukama uye yakabatana mukufambirana nechikamu cheA.Kana mutoro ukaramba usina kuchinjwa, Kana ikozvino yechikamu A yakakura zvikuru, kana ikafamba kwenguva yakareba, kupemha kwechikamu ichi kunenge kuchipisa nekupisa.Mushure mekunge chikamu chesimba charasika, mota inogona kuramba ichimhanya, asi kumhanya kunodonhawo zvakanyanya, kutsvedza kunova kwakakura, uye chiyero cheiyo magineti yekucheka conductor inowedzera.Panguva ino, B-phase winding yakavhurika-yakatenderedzwa, uye A uye C chikamu mhepo inotenderera inova munhevedzano uye inopfuura Yakawandisa ikozvino uye kwenguva refu kushanda kuchaita kuti maviri-chikamu mhepo inopisa panguva imwe chete. ratidza pano kuti kana mota yakamira ikashaya chikamu chimwe chemagetsi uye ikabatidzwa, kazhinji inongoita ruzha uye haikwanise kutanga.Izvi zvinodaro nekuti iyo symmetrical yechitatu-chikamu inochinjisa ikozvino inopihwa kune mota inoburitsa denderedzwa inotenderera magineti mumusimboti we stator.Nekudaro, kana chimwe chikamu chemagetsi chisipo, imwe-phase pulsating magineti inogadzirwa mukati meiyo stator core, iyo isingaite kuti mota igadzire yekutanga torque.Naizvozvo, mota haigone kutanga kana chikamu chemagetsi chisipo.Nekudaro, panguva yekushanda, elliptical inotenderera magineti ine yakakwirira-nhatu-chikamu harmonic zvikamu inogadzirwa mumhepo gap remota.Naizvozvo, mota inomhanya inogona kuramba ichimhanya mushure mekurasikirwa kwechikamu, asi iyo magineti yakakanganiswa uye inokuvadza ikozvino chikamu chinowedzera zvakanyanya., inopedzisira yaita kuti kumonereka kutsva.
Zvinoenderana nhanho dzekupikisa: Hazvina mhosva kuti mota yakamira here kana kuti ine simba, kukuvadza kwakananga kunokonzerwa nekurasikirwa kwechikamu ndechekuti chikamu chimwe kana maviri mapepo emota anopisa kana kutopisa.Panguva imwecheteyo, kushanda kwepamusoro kwetambo dzemagetsi kunomhanyisa kuchembera kuchembera.Kunyanya muiyo static state, kushomeka kwechikamu kunoburitsa yakakiyiwa rotor ikozvino kanoverengeka iyo yakayerwa ikozvino mumhepo inotenderera.Iyo yekumhanyisa kupisa yekumhanyisa inokurumidza uye yakakomba kupfuura iyo yakangoerekana yarasikirwa nechikamu panguva yekushanda.Naizvozvo, kana isu tichiita zuva nezuva kugadzirisa uye kuongorora mota, isu tinofanirwa kuita ongororo yakazara uye kuyedzwa kweinowirirana MCC inoshanda unit yemota.Kunyanya, kuvimbika kwemutoro switch, tambo dzemagetsi, uye static uye dynamic contacts inofanira kunyatsotariswa.Dzivirira kushanda kwechikamu chekurasikirwa.
