Isantya esiphezulu se-AC Motor
Injini ye-ACsisixhobo esiguqula amandla ombane ombane otshintshanayo abe ngamandla omatshini.Imoto ye-AC ibandakanya ubukhulu becala i-electromagneting winding okanye i-stator esasazwayo ejikelezayo esetyenziselwa ukuvelisa indawo yemagnethi kunye ne-armature ejikelezayo okanye i-rotor.I-motor yenziwa ngokusebenzisa i-phenomenon yokujikeleza i-coil yamandla kwintsimi yamagnetic ngamandla.Kukho iintlobo ezimbini zeenjini ze-AC: iimotor ze-AC ezihambelanayo kunye neenjini zokungenisa.
Umoya we-stator wesigaba sesithathu se-AC motor ngokusisiseko iikhoyili ezintathu ezihlukaniswe ngama-degrees angama-120 ukusuka komnye nomnye, ezidityaniswe kunxantathu okanye kwimilo yeenkwenkwezi.Xa inqanaba lesithathu langoku lisetyenzisiwe, intsimi yamagnetic yenziwa kwikhoyili nganye, kwaye iindawo ezintathu zamagnetic zidityanisiwe ukufumana indawo ejikelezayo yamagnetic.
Injini ye-ACIqulethe i-stator kunye ne-rotor, kwaye kukho iindidi ezimbini zeenjini ze-AC: i-synchronous AC motor kunye ne-induction motor.Zombini ezi ntlobo zeenjini zivelisa umhlaba ojikelezayo wamagnetic ngokudlula i-AC yangoku kwi-stator winding, kodwa i-rotor winding ye-synchronous AC motor idla ngokufuna ukubonelelwa nge-DC yangoku (i-excitation yangoku) yi-exciter, ngelixa i-rotor winding ye-induction motor ingenzi. kufuneka ityiswe ngomsinga.
Umoya we-stator wesigaba sesithathu se-AC motor ngokusisiseko iikhoyili ezintathu ezihlukaniswe ngama-degrees angama-120 ukusuka komnye nomnye kwaye zixhunywe kunxantathu okanye kwimilo yeenkwenkwezi.Xa umbane wesigaba sesithathu sisetyenzisiweyo, intsimi yamagnetic yenziwe kwikhoyili nganye, kwaye iindawo ezintathu zidibaniswe ukufumana indawo ejikelezayo.Xa i-current igqibezela ukungcangcazela okugcweleyo, intsimi yamagnetic ejikelezayo ijikeleza kanye iveki enye, ngoko ke, ii-revolutions ngomzuzu womhlaba ojikelezayo wemagnethi N=60f.I-equation f kukuphindaphinda konikezelo lwamandla.
Iimotor ze-AC zinokuhlelwa kwiimotor ezihambelanayo kunye neenjini ze-asynchronous (okanye ii-motor non-synchronous motors) ngokwezinga lokujikeleza kwe-rotor.Isantya se-rotor se-synchronous motor sihlala sifana nesantya sentsimi yamagnetic ejikelezayo kungakhathaliseki ukuba ngumthwalo, ngoko ke le santya sibizwa ngokuba yi-synchronous speed, kwaye njengoko kukhankanyiwe ngasentla, kumiselwa kuphela ngokuphindaphindiweyo kokunikezelwa kwamandla.Isantya se-asynchronous motor asitshintshi, kodwa kuxhomekeke kubukhulu bomthwalo kunye nombane wokunikezelwa kwamandla.Phakathi kweenjini ze-asynchronous zamanqanaba amathathu, kukho iimotor ezingaphindi zilungise kunye neemotor ezilungisayo.Uninzi lweemotor ezizii-asynchronous ekusebenzeni ziimotor zokungenisa ngaphandle kwesilungisi (kodwa iparallel kunye nothotho lweemotor ezikwinqanaba lesithathu le-asynchronous rectifier zinezibonelelo zesantya esihlengahlengiswayo kuluhlu olubanzi kunye namandla aphezulu), kwaye isantya saso sihlala singaphantsi kwesantya esihambelanayo. .
Usetyenziso oluphambili
Injini ye-ACinokusebenza ngokufanelekileyo, kwaye akukho msi, uthuli kunye nevumba, akukho kungcoliseka kwendalo, kunye nengxolo encinci.Ngenxa yoluhlu lwayo lweenzuzo, isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ezifana nemveliso yezoshishino kunye nezolimo, ukuthutha, ukukhusela ilizwe, izixhobo zorhwebo kunye nekhaya, izixhobo zombane zonyango, njl.
