Direct tam sim no (DC) thiab alternating tam sim no (AC) motors yog ob hom hluav taws xob siv hluav taws xob. Ua ntej sib tham txog qhov sib txawv ntawm ob hom no, cia peb xub nkag siab tias lawv yog dab tsi.
Lub DC lub cev muaj zog yog lub tshuab hluav taws xob hloov hluav taws xob uas tuaj yeem hloov hluav taws xob hluav taws xob rau hauv lub zog siv hluav taws xob (kev sib hloov). Nws kuj tseem siv tau los ua lub tshuab hluav taws xob uas hloov cov tshuab hluav taws xob (kev sib hloov) rau hauv hluav taws xob hluav taws xob (DC). Thaum lub DC lub cev muaj zog los ntawm qhov ncaj qha tam sim no, nws tsim ib qho chaw sib nqus hauv nws lub stator (nyob ruaj ruaj ntawm lub cev muaj zog). Lub teb attracts thiab repels hlau nplaum ntawm lub rotor (spinning ib feem ntawm lub cev muaj zog). Qhov no ua rau lub rotor tig. Txhawm rau kom lub rotor tsis tu ncua tig, lub commutator, uas yog lub tshuab hluav taws xob hloov hluav taws xob siv hluav taws xob tam sim no rau cov windings. Lub rotating torgue tsis tu ncua yog tsim los ntawm thim rov qab cov kev taw qhia tam sim no nyob rau hauv rotating winding txhua ib nrab tig.
DC motors muaj lub peev xwm los tswj lawv qhov nrawm, uas yog qhov tsim nyog rau kev siv tshuab. DC motors muaj peev xwm pib tam sim ntawd, nres thiab thim rov qab. Qhov no yog ib qho tseem ceeb rau kev tswj xyuas kev ua haujlwm ntawm cov khoom siv ntau lawm. Raws li ua raws li,XBD-4070 uayog ib qho ntawm peb cov DC motors nrov tshaj plaws.
Ib yam li DC lub cev muaj zog, qhov hloov pauv tam sim no (AC) rotor npog cov hluav taws xob hluav taws xob rau hauv lub zog hluav taws xob (kev sib hloov). Nws kuj tseem siv tau los ua lub tshuab hluav taws xob uas hloov cov tshuab hluav taws xob (kev xaiv tsa) rau hauv hluav taws xob hluav taws xob (AC).
Feem ntau AC motors tau muab faib ua ob hom. Lub cev muaj zog synchronous thiab lub cev muaj zog asynchronous. Cov tom kawg yuav yog ib theem lossis peb theem. Nyob rau hauv lub AC lub cev muaj zog, muaj ib lub nplhaib ntawm tooj liab windings (ua rau lub stator), uas yog tsim los tsim ib tug rotating magnetic teb. Raws li cov windings yog powered los ntawm AC hluav taws xob lub zog, lub magnetic teb, lawv tsim ntawm lawv tus kheej induces ib tug tam sim no nyob rau hauv lub rotor (spinning ib feem). Qhov induced tam sim no tsim nws tus kheej magnetic teb, uas tawm tsam cov magnetic teb los ntawm stator. Kev sib cuam tshuam ntawm ob lub teb ua rau nws rotor tig. Nyob rau hauv lub asynchronous lub cev muaj zog muaj qhov sib txawv ntawm ob lub nrawm. Cov khoom siv hluav taws xob hauv tsev feem ntau siv AC lub cev muaj zog vim tias cov khoom siv hluav taws xob hauv tsev yog hloov tam sim no (AC).
Qhov sib txawv ntawm DC thiab AC lub cev muaj zog:
● Cov khoom siv hluav taws xob sib txawv. Thaum DC motors yog tsav los ntawm cov tam sim no ncaj qha, AC motors yog tsav los ntawm alternating tam sim no.
● Nyob rau hauv AC motors, lub armature nyob ruaj ruaj thaum lub magnetic teb tig. Nyob rau hauv DC motors lub armature rotates tab sis cov magnetic teb tseem nyob ruaj ruaj.
● DC lub cev muaj zog tuaj yeem ua tau raws li kev cai du thiab kev lag luam yam tsis muaj khoom siv ntxiv. Kev tswj ceev yog ua tiav los ntawm kev nce lossis txo cov input voltage. AC motors reauire siv cov khoom siv zaus hloov pauv hloov ceev.
Qhov zoo ntawm AC motors muaj xws li:
● Tsawg pib lub zog xav tau
● Kev tswj tau zoo dua pib cov qib tam sim no thiab kev nrawm
● Kev hloov kho dav dua rau cov kev xav tau sib txawv thiab hloov ceev thiab qhov xav tau torque
● Zoo dua durability thiab ntev
Qhov zoo ntawm DC motors muaj xws li:
● Kev txhim kho yooj yim thiab kev saib xyuas yuav tsum tau ua
● Lub zog pib thiab lub zog siab dua
● Lub sijhawm teb sai dua rau kev pib / nres thiab nrawm dua
● Dav ntau yam rau cov kev xav tau ntawm qhov sib txawv
Piv txwv li, yog tias koj muaj lub tshuab hluav taws xob hauv tsev, nws feem ntau yuav siv AC lub cev muaj zog vim nws txuas ncaj qha rau koj lub tsev AC lub zog hluav taws xob, ua rau nws yooj yim rau siv thiab tsis tshua muaj txij nkawm. Cov tsheb hluav taws xob, ntawm qhov tod tes, yuav siv DC motors vim nws xav tau kev tswj xyuas meej ntawm lub cev muaj zog thiab lub zog kom muaj kev tsav tsheb zoo thiab nrawm.
