Hluav taws xob paub txog tias cov neeg siv hluav taws xob yuav tsum txawj ntse
1. Tam sim no ntawm ib lub tshuab hluav taws xob ib zaug nyob rau hauv tsis muaj load yog txawv los ntawm lub ntsiab magnetic flux, thiab muaj lub kaum ntse ntse theem txawv aFe vim hais tias muaj ib qho kev siv tam sim no. Qhov tsis muaj-thauj tam sim no yog lub cev ntaj ntsug vim tias muaj ib qho loj thib peb.
2. AC lub tam sim no ntws hauv qhov chaw sib tw ntawm DC lub cav. Txawm li cas los xij, lub sij hawm tam sim no ntws hauv kev teb winding yog ib qho ncaj nraim tam sim no. Qhov kev tawm tsam ntawm DC lub tsheb muaj xws li lwm tus excitation, shunt excitation, series excitation, thiab excitation compound.
3. Daim npav EMF qhia ntawm DC lub cav yog E = CEFn; thiab kev qhia electromagnetic torque yog Tem = CTFI.
4. Tus nab npawb ntawm cov kab hlau txuas mus ib txhis ntawm DC tsav yog ib txwm khub. Tus najnpawb ntawm cov ceg ntoo sib txuas ntawm AC loop tsis yog tib yam nkaus.
5. Hauv DC lub cav, cov khoom ntawm qhov khij ib zaug yog txuas nrog ib ntawm sab saum toj ntawm lwm qhov. Seb nws yog ib lub voj voog winding los yog ib txoj hlua khau xwb, qhov txuas ntawm commutator txuas tag nrho cov khoom ua ke los tsim ib zaug xwb lub voj.
6. Asynchronous motors tseem hu ua induction motors vim hais tias lub rotor tam sim no ntawm asynchronous motors yog generated by electromagnetic induction.
7. Thaum lub cav asynchronous stepped, lub pib lub zog txo, thiab lub pib lub zog yuav txo tau hauv cov kev faib rau lub xwmfab ntawm qhov pib ntawm lub caij winding.
8. Thaum lub amplitude thiab zaus ntawm qhov kev sab nraud sab nraud yog qhov tseem ceeb, qhov teeb meem saturation ntawm tus tub ntxhais ntawm qhov kev hloov tshuab yog qhov tseem ceeb, thiab qhov kev cia siab excitation kuj tseem tsis hloov.
9. Cov yeeb yam luv luv ntawm lub tshuab synchronous yog ib txoj kab ncaj nraim. Thaum cov theem peb theem ntawm cov kab nrig luv tshwm sim, qhov sib npaug ntawm hlau nplaum yog unsaturated; Thaum twg peb theem ntawm symmetrical steady-state luv luv Circuit Court, lub luv Circuit Court yog ib qho tseem ceeb ntawm txoj kev siv xaim ntawm txoj kab ncaj nraim.
10. Tam sim no hauv qhov excitation winding ntawm lub tshuab synchronous yog DC tam sim no. Qhov kev cia siab hom feem ntau xam cov excitation ntawm tus excitation generator, excitation ntawm lub rectifier zoo li qub, thiab excitation ntawm cov teb rectifier.
11. Tsis muaj ib qho kev sib haum xeeb nyob rau hauv peb-theem hluav taws xob hluav taws xob; cov kabmob peb theem ntawm cov kabmob symmetrical yog peb theem tam sim no, thiab tsis muaj ntau ntau yam ntawm 3 nyob rau hauv cov hluavtaws magnetomotive force.
12. Cov qauv hluav taws xob 3 theem feem ntau xav kom muaj ib sab txuas nrog ib daim duab peb sab los yog ib qho chaw hauv paus ntawm ib sab. Vim hais tias qhov sib txuas ntawm qhov sib tsoo ntawm qhov peb-theem hloov hluav taws xob yuav tsum muaj ib txoj kev los ntawm peb qhov kev sib raug zoo tam sim no.
13. Thaum lub caij sib thooj ntawm peb theem pib tshwm sim yog qhov peb theem tam sim no, qhov teeb meem thib tsib nyob rau hauv lub zog hluavtaws magnetomotive rov qab; xya harmonic yog rau pem hauv ntej.
14. Cov yam ntxwv ntawm txhua yam khoom xyaw ntawm DC-tsav DC lub cev muaj zog. Cov yam ntxwv ntawm txhua yam ntawm DC lub cev muaj zog.
15. Qhov kev hloov ua lub luv luv ntawm qhov kev sib tw yuav ntsuas tau cov pa tawm ntawm qhov kev hloov tshuab hluav taws xob; qhov kev xeem tsis muaj kev ntsuas yuav ntsuas qhov kev sib tw impedance parameter ntawm qhov kev sib tw.
