Muchina unoshandura simba remagetsi kuita simba remakanika unonzi mota yemagetsi. Idzi dziri nyore kugadzira, dzinoshandiswa zviri nyore, dzakachipa, dzinoshanda zvakanaka, hadzina kugadziriswa zvakanyanya, uye dzakavimbika. Mota dzemagetsi dzinoshandisa zvikamu zvitatu dzakasiyana nedzimwe mhando dzemota dzemagetsi. Musiyano mukuru ndewekuti hapana kubatana kwemagetsi kubva kurotor winding kuenda kune chero chinhu chinopihwa. Current inodiwa uye voltage murotor circuit zvinopihwa ne induction kubva ku stator winding. Ichi ndicho chikonzero chekudaidza kuti i induction motor. Chinyorwa chino chinotsanangura Squirrel cage induction motor, inova imwe yemhando dzemota dzemagetsi dzinoshandisa zvikamu zvitatu.
Chii chinonzi Squirrel Cage Induction Motor?
Tsananguro: Mota yeSquirrel cage ndeimwe yemhando dzemota dzeinduction. Kuti igadzire kufamba, inoomesa electromagnetism. Sezvo shaft yekubuda yakabatana nechikamu chemukati cherotor chinotaridzika sekeji. Saka inonzi squirrel cage. Makapu maviri-end kureva, akatenderera muchimiro anobatanidzwa ne rotor bars. Izvi zvinoitwa zvichibva paEMF kureva, inogadzirwa ne stator. Iyi EMF inogadzirwawo imba yekunze yakagadzirwa ne laminated metal sheets uye wire coiling. Zvikamu zviviri zvikuru zvechero rudzi rwe induction motor i stator ne rotor. Squirrel cage inzira iri nyore yekudhonza electromagnetic induction effect. Mota ye induction ye squirrel cage ine 4-pole inoratidzwa pazasi.
Nheyo yekushanda kweSikirini yeSikirini
Kushanda kwemota yeSquirrel induction kunoenderana nepfungwa yeelectromagnetism. Kana stator winding ikapihwa thee-phase AC, inogadzira rotating magnetic field (RMF) ine speed inonzi synchronous speed. Iyi RMF inokonzera voltage inokonzerwa ne rotor bars. Saka, iyo current inoyerera nepakati payo. Nekuda kweaya ma rotor currents, self magnetic field inogadzirwa iyo inosangana ne stator field. Zvino, sekureva kwenheyo, rotor field inotanga kupikisa chikonzero chayo. Kana RMF yabata rotor moment, rotor current inodonha kusvika zero. Ipapo paisazova nehukama pakati pe rotor ne RMF.
Saka, simba re zero tangential rinoonekwa ne rotor uye rinodzikira kwechinguva. Mushure mekudzikira uku panguva ye rotor, rotor current inokonzerwa zvakare nekuvakwazve kwekufamba pakati pe RMF ne rotor. Nokudaro simba re tangential re rotor rekutenderera rinodzorerwa uye rinotanga nekutevera RMF. Muchiitiko ichi, rotor inochengetedza kumhanya kwakasimba, kuri pasi pe kumhanya kwe RMF uye kumhanya kwakabatana. Pano, musiyano uripo pakati pekumhanya kwe RMF ne rotor unoyerwa muchimiro chekutsvedza. Kuwanda kwekupedzisira kwe rotor kunogona kuwanikwa nekuwedzera kwekutsvedza uye frequency yekugovera.
Kuvaka Mota yeSquirrel Cage Induction
Zvikamu zvinodiwa pakuvaka injini ye induction ye squirrel cage ndeizvi: stator, rotor, fan, ma bearings. Stator iyi ine ma three-phase winding akaparadzana nemakanika uye emagetsi ane 3-phase winding ine simbi ne core. Kuti pave ne AC current isingade kuyerera zvakanyanya, ma winding acho anoiswa pa laminated iron core.
Rotor inoshandura simba remagetsi rakapihwa kuita simba remagetsi. Shaft, core, short-circuited copper bars ndizvo zvikamu zverotor. Kuti isanyanya kuvhunduka uye eddy currents zviri kukonzera kurasikirwa nemagetsi, rotor inonamirwa. Uye ndinoraira kuti isavhunduke, maconductor anotsveyama izvo zvinobatsirawo kupa chiyero chakanaka chekuchinja.
Feni yakasungirirwa kumashure kwerotor kuti ishandise kupisa inobatsira kuchengetedza tembiricha yemota iri pasi pemuganhu wekupisa. Kuti itenderere zvakanaka, mabheringi anowanikwa mumota.
Musiyano uripo pakati peSquirrel Cage Induction Motor neSlip Ring Induction Motors.
Zvakanakira
Zvakanakira zvemota ye squirrel cage induction zvinosanganisira zvinotevera:
Kuvaka kuri nyore uye kwakasimba.
Mari shoma yekutanga pamwe chete neyokugadzirisa.
Inochengetedza kumhanya kwakasimba.
Kukwanisa kuremedza zvinhu zvakanyanya.
Kurongeka kuri nyore kwekutanga.
Simba guru.
Kurasikirwa kwakaderera kwemhangura yerotor.
Kushanda zvakanaka kwazvo.
Zvakashata
Zvakashata zvemota ye squirrel cage induction zvinosanganisira zvinotevera.
