Hluav taws xob machinery
Peb nyob rau hauv lub tiag tiag dej hiav txwv ntawm lub zog, nws yog tag nrho cov nyob ib ncig ntawm peb. Txawm nyob ruaj ruaj pob zeb dag nyob rau hauv txoj kev, muaj lub peev xwm mus ua hauj lwm. Tej zaum nws yog ib qho nyuaj rau cov ntseeg, tab sis lub zog yog ib tug. Nws tau hloov, hloov cov xwm. Qhov no tej khoom vaj tse yog siv los ntawm tus neeg hluav taws xob lub tsheb.
Yog hais tias lub tswv yim fais fais fab yog nkag, thiab cov qhov tso zis yog hloov mus rau hauv cov neeg kho tshuab ua hauj lwm nyob rau hauv daim ntawv ntawm cov ncej kev sib hloov, nws yuav tau hais qhov tseeb hais tias nws yog ib tug lub cev muaj zog. Nyob rau hauv lem, tus hloov dua siab tshiab ntawm cov neeg kho tshuab ua hauj lwm mus rau hauv hluav taws xob raug cov generator. Ib qho tseem ceeb feature yog lub fact tias cov tib hluav taws xob tshuab tsiag ntawv los ntawm tseem ua tau hauj lwm raws li ib tug neeg siv (xyaw) thiab chaw tsim tshuaj paus (generator) lub hwj chim. Qhov no yog vim tib ntaus ntawv. Txawm li cas los, vim rau qhov tsim nta ntawm lub lag luam nyob rau hauv lub "non-haiv neeg" hom yog yus muaj los ntawm ib tug tsawg dua efficiency.
Electric DC machines raug muab faib ua ob chav kawm: cov inductor thiab collector. Cov feem ntau lug siv thib ob (muaj tus cwj pwm txhuam mechanism). Lub hauv paus ntsiab lus ntawm cov lag luam yog raws li nram no: nyob rau hauv ib tug taag ib feem ntawm lub tshuab (stator) yog muab tso rau ib tug mus tas magnet, ua rau lub kab teb.
Armature winding yuav tsum yog los ntawm ib tug plurality ntawm ntas ntawm tooj liab hlau, kev cob cog rua rau hauv xws li ib txoj kev uas qhov pib thiab qhov kawg ntawm lub tso zis rau lub opposite lamella collector. Externally rau cov pins los ntawm txoj kev carbon txhuam nkag DC voltage. Thiab yog hais tias muaj yog ib tug raug kaw Circuit Court, ces ib tug hluav taws xob tam sim no. Tsiv xwb muaj generated nyob ib ncig ntawm nws tus kheej tus kheej qhov magnetic teb uas pib mus nrog cov stator teb. Raws li ib tug tshwm sim, muaj ib tug dag zog yuam uas forces lub thauj tog rau nkoj tig. Nws piav xwb lub ntsiab lus tseem ceeb, tab sis lawv yog txaus kom to taub yuav ua li cas hluav taws xob lub tsheb ua hauj lwm DC. Nws yog ib nqi sau cia xwb ib tug universal collector lub cev muaj zog muaj ib tug qauv xam qhovkev DC machines, nws muaj peev xwm mus ua hauj lwm los ntawm lub tsev network 220 B. Qhov no yog tau ua tsaug rau lub serial kev twb kev txuas txoj kev ntawm lub armature thiab teb windings. Cov tsev neeg electric tes cov cuab yeej siv los ntawm lawv.
Hluav taws xob cov machine AC structurally yooj yim thiab ntau txhim khu kev qha, thiab txo nqi ntau lawm. Faib mus rau hauv synchronous, uas tus neeg kho tshuab ceev uas lub rotor puv, tib yam li lub zaus ntawm kiv puag ncig ntawm lub stator teb thiab asynchronous versions nyob rau hauv uas lub rotor teb lags (slips). Thawj ua kom zoo dua kev siv ntawm qhov chaw nyob ntawm ntau tshaj 100 kW.
Tej yam yooj yim hluav taws xob cav AC hais peb-theem asynchronous nas-tawb motors (nas tawb). Nyob rau stator cov txheej txheem staggered txheeb ze rau ib leeg ntawm 120 ° peb windings. Nws yog lawv ib tug alternating tam sim no yog thov lub duas paub theem. Lub rotor muaj ib tug kauj, ib tug kaw-Circuit Court, li no txoj kev ua ib tug Circuit Court rau lub tso cai ntawm lub ntxias tam sim no. Nws yuav tsum txhawb cov stator-kauj tug yog generated nyob ib ncig ntawm lub magnetic teb - qhov no yog ib tug ntawm cov yooj yim zog ntawm cov directional zog ntawm electrons. Thiab txij li thaum lub alternating tam sim no, thiab cov rotating teb tau. Nws cov kab tshuam nro windings thiab rotor windings ua ib qho kev ntxias tam sim no (siv kev cai lij choj ntawm electromagnetic induction). Thiab yog hais tias muaj ib lub suab hais nrog ib tug xwb, ces nyob ib ncig ntawm lawv, nyob rau hauv lem, kuj zoo nkaus li ib tug sib nqus teb. Nws kuj rotates (kev taw qhia yuav muaj nyob los ntawm kev siv lub right-hand txoj cai). Raws li ib tug tshwm sim, muaj ob magnetic teb hauv lub tsheb lub cev. Ces txhua yam yog yooj yim: ua tsaug rau txoj kev cai Ampere yog ib tug dag zog yuam uas nyhav displace winding, raws li zoo raws li lub rotor ncej yog mounted rau bearings, cov quab yuam tsim ib tug torque. Mus ua ib tug ua hauj lwm muaj peev xwm tsuas yog kev cob cog rua rau lub Actuator ncej.
