Dab tsi yog a Permanent Magnet Synchronous Tsav?
Peb tuaj yeem nkag siab yooj yim lub cev muaj zog ua "hloov hluav taws xob hluav taws xob rau hauv lub zog sib hloov."
Tag nrho cov motors muaj ob lub hauv paus tseem ceeb: lub stator nyob ruaj ruaj thiab lub rotating rotor.
Lub npe "sab mus li magnet synchronous lub cev muaj zog" tuaj yeem tawg ua ob ntu kom nkag siab yooj yim thiab nco:
1. Permanent Magnet:
Lub rotor ntawm lub cev muaj zog yog nruab nrog cov hlau nplaum ruaj khov (inherently sib nqus, tsis tas yuav muaj hluav taws xob los tsim cov hlau nplaum). Qhov no yog qhov loj tshaj qhov sib txawv ntawm nws thiab ib tug pa lub cev muaj zog.
Cov motors ib txwm xav tau hluav taws xob los ua kom muaj zog sib nqus hauv lub rotor, thaum lub cev muaj zog no nyob ntawm lub zog sib nqus ntawm cov hlau nplaum ruaj khov, tsis tas yuav muaj lub zog ntxiv.
2. Synchronization:
Thaum lub cev muaj zog ua haujlwm, qhov kev sib hloov ceev ntawm lub rotor yog tib yam li kev sib hloov ceev ntawm cov hlau nplaum tsim los ntawm stator tom qab nws muaj zog; lawv yog synchronized kiag li. Tsis muaj qhov sib txawv ntawm qhov nrawm, ua rau muaj kev ua haujlwm zoo dua thiab ruaj khov.
Nws ua haujlwm li cas?
Lub stator yog qhov tseem ceeb "rotating magnetic field." Thaum alternating tam sim no yog siv rau lub stator, nws generates ib rotating magnetic teb, rotating tsis tu ncua thiab stably.
Cov hlau nplaum tas mus li ntawm lub rotor yog "cov hlau nplaum ruaj khov," ua haujlwm ntawm lub hauv paus ntsiab lus ntawm "zoo li ncej repel, tsis zoo li cov ncej nyiam."
Lub rotating magnetic teb ntawm stator nrees attracts thiab tsav lub rotor tig nrog rau nws. Lub rotor rotates nyob rau tib lub ceev raws li lub magnetic teb, ua hauj lwm synchronously thoob plaws hauv tag nrho cov txheej txheem.
Tag nrho cov txheej txheem cuam tshuam tsis tas yuav muaj kev sib txhuam lossis kev siv fais fab; Kev sib hloov tsuas yog tsav los ntawm cov hlau nplaum, uas yog qhov laj thawj tseem ceeb rau nws txoj kev ua haujlwm siab thiab txuag hluav taws xob.
Core Advantages ntawm Permanent Magnet Synchronous Motors
Cov txiaj ntsig tseem ceeb ntawm cov hlau nplaum ruaj khov synchronous motors uas tau ua rau lawv lub ntsiab tsav lub cev muaj zog yog nyob rau hauv plaub lub ntsiab lus:
1. Kev siv hluav taws xob tsawg heev thiab kev ua haujlwm siab
Lub rotor siv cov hlau nplaum tas mus li nrog lawv tus kheej lub zog sib nqus, tshem tawm qhov xav tau ntawm hluav taws xob excitation thiab txo qis zog poob.
Thaum cov motors zoo tib yam muaj qhov ua tau zoo ntawm kwv yees li 70% -80%, cov hlau nplaum ruaj khov synchronous motors tuaj yeem ua tau zoo tshaj 90%. Kev siv lawv nyob rau hauv lub zog tshiab tsheb tuaj yeem txhim kho kev tsav tsheb ncaj qha.
2. Qhov loj me, lub teeb yuag, thiab kev ua haujlwm muaj zog
Nyob rau tib lub zog tso zis, nws qhov loj thiab qhov hnyav tsuas yog ib nrab ntawm lub cev muaj zog.
3. Lub cev compact muab lub zog ntau dua (pib lub zog), ua rau kom nrawm dua thiab muaj zog dua rau lub tsheb fais fab, tsis tas siv ntau qhov chaw hauv lub tsheb.
4. Kev ua haujlwm du thiab suab nrov tsawg
Vim hais tias cov speeds yog zoo kawg nkaus synchronized, tsis muaj jerking los yog ceev sib txawv thaum lub sij hawm ua hauj lwm, thiab lub vibration amplitude yog tsawg.
Qhov kev nyob ntsiag to thiab du uas koj tau txais thaum tsav tsheb fais fab lossis siv lub tshuab cua txias inverter yog ua tsaug rau lub cev muaj zog no.
5. Ceev ceev tswj thiab muaj zog adaptability
Nws tuaj yeem tswj tau qhov nrawm, muab lub zog txaus ntawm qhov nrawm thiab kev ua haujlwm ruaj khov ntawm kev kub ceev. Txawm hais tias nws yog lub tsheb nkag ntawm qhov ceev qis lossis caij nkoj ntawm kev kub ceev, nws hloov tau zoo rau ob qho tib si qis - zog thiab siab - lub zog ua haujlwm ntawm cov khoom siv hauv tsev.
