Isivinini esikhulu se-AC Motor
Injini ye-ACiyidivayisi eguqula amandla kagesi wamanje ashintshanayo abe amandla emishini.Injini ye-AC iqukethe ikakhulukazi i-electromagnet winding noma i-stator winding esabalalisiwe esetshenziselwa ukukhiqiza inkambu kazibuthe kanye ne-armature ejikelezayo noma i-rotor.I-motor yenziwa ngokusebenzisa isenzeko sokuzungezisa ikhoyili enamandla endaweni kazibuthe ngamandla.Kunezinhlobo ezimbili zama-AC motors: ama-synchronous AC motors nama-induction motors.
I-stator winding yesigaba sesithathu se-AC motor ngokuyisisekelo ngamakhoyili amathathu ahlukaniswe ngamadigri angu-120 ukusuka kwelinye, axhunywe kunxantathu noma umumo wenkanyezi.Lapho kusetshenziswa wamanje wezigaba ezintathu, inkambu kazibuthe ikhiqizwa ikhoyili ngayinye, futhi izindawo ezintathu zikazibuthe ziyahlanganiswa ukuze kutholwe inkambu kazibuthe ejikelezayo.
Injini ye-ACiqukethe i-stator ne-rotor, futhi kunezinhlobo ezimbili zamamotho e-AC: i-synchronous AC motor kanye ne-induction motor.Zombili izinhlobo zamamotho zikhiqiza amandla kazibuthe ajikelezayo ngokudlula i-AC yamanje ku-stator winding, kodwa i-rotor winding ye-synchronous AC motor ngokuvamile idinga ukuhlinzekwa nge-DC current (excitation current) yi-exciter, kuyilapho ukuvuthwa kwe-rotor kwe-induction motor kungakwenzi. kudingeka ukondliwa nge-current.
I-stator winding yesigaba sesithathu se-AC motor ngokuyisisekelo ngamakhoyili amathathu ahlukaniswe ngamadigri angu-120 ukusuka kwelinye futhi axhunywe kunxantathu noma umumo wenkanyezi.Lapho i-current yezigaba ezintathu isetshenziswa, insimu kazibuthe ikhiqizwa ikhoyili ngayinye, futhi izinkambu ezintathu ziyahlanganiswa ukuze kutholwe insimu ejikelezayo.Lapho i-current iqeda ukudlidliza okukodwa okugcwele, inkambu kazibuthe ezungezayo izungeza ncamashi isonto elilodwa, ngakho-ke, ukuguqulwa ngomzuzu wendawo kazibuthe ezungezayo N=60f.I-equation f imvamisa yokunikezwa kwamandla.
Amamotho e-AC angahlukaniswa abe amamotho e-synchronous kanye nama-asynchronous motors (noma ama-non-synchronous motors) ngokwezinga lokujikeleza kwe-rotor.Ijubane le-rotor le-synchronous motor lihlala lifana nejubane lensimu yamagnetic ejikelezayo kungakhathaliseki ukuthi umthwalo ungakanani, ngakho-ke leli jubane libizwa ngokuthi isivinini sokuvumelanisa, futhi njengoba kushiwo ngenhla, kunqunywa kuphela imvamisa yokunikezwa kwamandla.Isivinini se-asynchronous motor asihlali njalo, kodwa sincike kusayizi womthwalo kanye ne-voltage yokunikezwa kwamandla.Phakathi kwezigaba ezintathu zama-asynchronous motors, kukhona ama-non-rectifier motors nama-rectifier motors.Iningi lama-asynchronous motors ekusebenzeni ama-induction motors ngaphandle kokulungisa kabusha (kodwa parallel kanye nochungechunge lwezigaba ezintathu ze-asynchronous rectifier motors anezinzuzo zejubane elilungisekayo ebangeni elibanzi namandla aphezulu), futhi ijubane layo lihlala lingaphansi kwejubane lokuvumelanisa. .
Izinhlelo zokusebenza eziyinhloko
Injini ye-ACinokusebenza kahle okuphezulu, futhi akukho ntuthu, uthuli nephunga, akukho ukungcoliswa kwemvelo, nomsindo omncane.Ngenxa yochungechunge lwezinzuzo zayo, isetshenziswa kabanzi emikhakheni ehlukahlukene efana nokukhiqizwa kwezimboni nezolimo, ezokuthutha, ukuvikela izwe, izinto zikagesi ezentengiselwano nezasendlini, imishini kagesi yezokwelapha, njll.
