Umatshini oguqula amandla ombane abe ngamandla oomatshini ubizwa ngokuba yi-electric motor. Ezi zilula ngoyilo, zisetyenziswa lula, zibiza kancinci, zisebenza kakuhle, azinakugcinwa kakhulu, kwaye zithembekile. Ii-induction motors zesigaba sesithathu zezinye zeentlobo kwaye zahlukile kwezinye iintlobo zee-electric motors. Umahluko ophambili kukuba akukho nxibelelwano lombane ukusuka kwi-rotor winding ukuya kuyo nayiphi na imithombo yobonelelo. Umbane ofunekayo kunye ne-voltage kwisekethe ye-rotor zibonelelwa yi-induction evela kwi-stator winding. Esi sisizathu sokubiza i-is njenge-induction motor. Eli nqaku lichaza i-Squirrel cage induction motor, enye yeentlobo zee-induction motor zesigaba sesithathu.
Yintoni iSquirrel Cage Induction Motor?
Inkcazo: Imoto yekheji yesquirrel yenye yeentlobo zeemoto zokungenisa. Ukuze ivelise intshukumo, iqinisa i-electromagnetism. Njengoko umngxuma wokukhupha uqhagamshelwe kwinxalenye yangaphakathi yerotor ejongeka njengekheji. Yiyo loo nto ibizwa ngokuba yikheji yesquirrel. Ii-caps ezinemilo emibini oko kukuthi, ezijikelezileyo zidibene neebha zerotor. Ezi zenziwa ngokusekelwe kwi-EMF oko kukuthi, eziveliswa yi-stator. Le EMF ikwaveliswa indlu yangaphandle eyenziwe ngamashiti esinyithi alaminethiweyo kunye ne-wire coiling. Iindawo ezimbini eziphambili zalo naluphi na uhlobo lwemoto yokungenisa yi-stator kunye ne-rotor. Ikheji yesquirrel yindlela elula yokutsala isiphumo sokungenisa i-electromagnetic. Imoto yokungenisa ikheji yesquirrel enezibonda ezi-4 iboniswe ngezantsi.
Umgaqo-nkqubo Wokusebenza Kwemoto Yokungenisa I-Squirrel Cage
Ukusebenza kwe-squirrel induction motor kusekelwe kumgaqo we-electromagnetism. Xa i-stator winding inikwe i-thee-phase AC, ivelisa i-rotary magnetic field (RMF) enesantya esibizwa ngokuba yi-synchronous speed. Le RMF ibangela i-voltage ebangelwa zii-rotor bars. Ngoko ke, loo current ihamba ngaloo nto. Ngenxa yale mijelo ye-rotor, kwenziwa i-self magnetic field esebenzisana ne-stator field. Ngoku, ngokomgaqo, i-rotor field iqala ukuchasana nesizathu sayo. Xa i-RMF ibamba umzuzu we-rotor, umbane we-rotor uyehla uye kwi-zero. Emva koko bekungayi kubakho mzuzu uhambelanayo phakathi kwe-rotor kunye ne-RMF.
Ngenxa yoko, amandla angenanto ajikajikayo afunyanwa yirotha aze anciphe okomzuzwana. Emva kolu nciphiso kumzuzu werotha, umsinga werotha uphinde ubangelwe kukwakhiwa kwakhona kwentshukumo ehambelanayo phakathi kwe-RMF kunye nerotha. Ngenxa yoko amandla ajikajikayo erotha yokujikeleza ayabuyiselwa kwaye aqale ngokulandela i-RMF. Kule meko, irotha igcina isantya esingaguqukiyo, esingaphantsi kwesantya se-RMF kunye nesantya esihambelanayo. Apha, umahluko phakathi kwesantya se-RMF kunye nerotha ulinganiswa ngendlela yokutyibilika. Isantya sokugqibela serotha sinokufunyanwa ngokuphindaphinda isantya sokutyibilika kunye nesantya sokubonelela.
Ukwakhiwa kweMoto yokungenisa iSigodlo sikaSquirrel
Iindawo ezifunekayo ekwakheni i-squirrel cage induction motor yi-stator, i-rotor, i-fan, ii-bearings. I-stator yenziwe nge-twiring ye-120 degrees ukusuka ngoomatshini nangombane ene-casing yesinyithi kunye ne-core. Ukuze kubonelelwe ngendlela yokungafuni ukuhamba okuphantsi okubangelwa yi-AC current, i-winding ifakwe kwi-core yesinyithi elaminethiweyo.
I-Rotor iguqula amandla ombane anikwe wona abe yimveliso yoomatshini. I-shaft, i-core, ii-short-circuited copper bars ziindawo ze-rotor. Ukuze kuthintelwe i-hysteresis kunye ne-eddy currents ezikhokelela ekulahlekelweni kwamandla, i-rotor ifakwa i-laminate. Kwaye ndiyalela ukuthintela ukugoba, ii-conductors zigobile nto leyo ekwanceda ukunika umlinganiselo olungileyo wotshintsho.
Ifeni eqhotyoshelwe ngasemva kwerotor ukuze kutshintshiselwe ubushushu inceda ekugcineni ubushushu obuphantsi komda wemoto. Ukuze ijikeleze kakuhle, kukho iibheringi kwimoto.
