AC daim npliag magnet synchronous lub cev qauv
Muaj ntau ntau hom hlau nplaum synchronous ntev, thiab cov waveforms ntawm qhov yuam kev electromotive quab yuam ntawm stator windings yuav muab faib ua ib sine yoj magnet synchronous tsav (PMSM) thiab ib tug trapezoidal tas li magnet synchronous tsav (BLDC). Lub stator ntawm cov sinusoidal mus tas li hlau nplaum synchronous lub cev muaj li ntawm peb-theem windings thiab hlau cores. Lub armature windings feem ntau txuas nrog Y-hom, thiab luv luv-muab faib windings yog siv; cov paib kis yog tsim los ua sine yoj los ua kom muaj lub suab yau rov qab electromotive force; lub rotor txais ib qho chaw ruaj khov Siv hloov ntawm hluav taws xob, tsis ntev li ntawm cov hluav taws xob ua kom muaj zog ntawm cov hluav taws xob yuav tsum muab faib ua peb pawg raws li txoj kev sib txuas ntawm cov hlau nplaum ntawm lub rotor: convex, embedded thiab embedded. Lub cav tau kawm nyob rau hauv daim ntawv no yog ib qho kev sib xyaw xyaw sine wave tas mus li lub tshuab synchronous. Tus qauv no muaj nyob rau hauv daim duab 1. Lub stator winding feem ntau tau ua ntau theem. Lub rotor yog tsim los ntawm cov hlau nplaum tas li raws li ib qho logarithm. Rau ob tog, tus tsav lub zog yog n = 60f / p, P yog tus ncej logarithm, thiab f yog qhov tam sim no.
Tam sim no, peb theem phase synchronous tam sim no muaj ob tug tswj hom, ib qho yog nws tswj (tseem hu ua zaus qhib-voj tswj); tus lwm tus yog tswj yus tus kheej (kuj paub tias kev tso tawm ntev-kev tswj hwm). Cov hom kev tswj tau ua kom yooj yim rau kev ceev nrawm ntawm nws tus kheej tswj cov teeb meem sab nraud. Nws tsis yog qhov yuav tsum paub cov lus qhia ntawm lub rotor, thiab qhib-voj tswj tswvyim ntawm qhov ntsuas qhov voltage feem ntau yog siv. Kev tswj tus kheej tswj lub tshuab synchronous tus kheej kuj tau hloov qhov kev sib hloov ntawm lub rotor los ntawm kev hloov lub zaus ntawm lub hwj huam lwm sab nraud. Tsis zoo li lwm hom kev tswj, qhov hloov ntawm sab nraud fais fab zaus muaj feem xyuam rau cov lus qhia ntawm lub rotor. Qhov siab dua tus rotor ceev, lub siab dua rau tus stator fais fab mov zaus. Qhov siab dua tus rotor ceev yog kho los ntawm qhov sib txawv ntawm qhov muaj qhov hloov ntawm qhov siv (lossis tam sim no) ntawm stator windings. Txij thaum tswj tus kheej tswj lub tshuab synchronous tsis muaj qhov teeb meem ntawm tawm-ntawm-kauj ruam thiab oscillation ntawm lub tshuab synchronous ntawm nws txoj kev tswj, thiab cov hlau nplaum ntawm cov hlau nplaum sib txuas synchronous tsis muaj txhuam thiab cov commutator, qhov ntim thiab zoo ntawm lub rotor yog txo, thiab qhov system zoo tuaj. Kev ntsuas ceev thiab kev khiav ceev, thiab kev ua tau zoo ntawm DC lub cev, yog li tus kheej tswj AC magnet synchronous lub cev siv rau hauv daim ntawv no, thaum peb theem hluav taws xob muaj peev xwm ntxiv rau cov theem peb theem ntawm cov kabmob, yuav tau tsim ib qho synchronous ceev rotating stator. Lub sib nqus field, qhov ceev ntawm lub tshuab synchronous rotor yog nruj me ntsis nrog cov hluav taws xob lwm zaus, thiab muaj ib yam dabtsi ua nrog rau qhov luaj li cas.
