Dab tsi yog Cov Txheej Txheem Tseem Ceeb ntawm Micro Tsav?

Rated voltage

Nws hais txog cov kab hluav taws xob ntawm stator winding hauv volt (V). Feem ntau, kev khiav hauj lwm voltage ntawm lub cev muaj zog yuav tsum tsis txhob siab tshaj lossis qis dua 5 feem pua ​​​​ntawm cov nqi ntsuas. Lub hwj chim mov voltage yuav tsum ua raws li qhov ntsuas voltage ntawm lub cev muaj zog. Qhov ntsuas hluav taws xob ntawm DC lub cev muaj zog feem ntau yog 220V, thiab DC lub cev muaj zog feem ntau muab los ntawm cov khoom siv hluav taws xob sib cais. Thaum xaiv qhov ntsuas hluav taws xob, nws feem ntau tsuas yog xav tau kev koom tes nrog cov khoom siv hluav taws xob. Qhov ntsuas hluav taws xob ntawm ac asynchronous lub cev muaj zog feem ntau yog 380V lossis 380V / 220V. Qhov voltage ntawm ib lub tshuab hluav taws xob feem ntau yog 220V thiab 50 HZ, thiab peb-theem generator feem ntau yog 380V thiab 50 HZ. Thaum lub zog ua haujlwm siab tshaj qhov ntsuas tus nqi, qhov sib nqus flux yuav nce ntxiv, uas yuav ua rau kom muaj zog tam sim no, thiab tam sim no ntau dua li qhov ntsuas tam sim no, ua rau lub cua sov tuaj. Nyob rau tib lub sijhawm, vim qhov nce ntawm cov hlau nplaum sib nqus, cov hlau poob kuj nce, ua rau cov tub ntxhais stator overheat; Thaum lub zog ua haujlwm qis dua tus nqi ntsuas, qhov tso zis torque txo qis, qhov nrawm nrawm, thiab qhov tam sim no kuj nce, ua rau cov cua kub dhau, uas yog qhov tsis zoo rau kev ua haujlwm ntawm lub cev muaj zog.

 

Tam sim no

1. Tsis muaj load tam sim no yog hais txog qhov tam sim no ntws mus rau hauv lub cev muaj zog nyob rau hauv qhov ntsuas ua haujlwm voltage, ntsuas lub hwj chim zaus, ntsuas capacitor, thiab tsis muaj kev khiav haujlwm (lub zog tso tawm ntawm lub ncej yog xoom), uas yog hu ua tsis muaj load. tam sim no. Unit: A los yog mA. Lub zog tsim los ntawm cov khoom uas tsis muaj kev thauj khoom tam sim no thiab qhov hluav taws xob feem ntau yog muab faib ua lub zog muaj peev xwm thiab thermal zog noj. Thermal zog yog lub cua sov ntawm lub cev muaj zog coil. Qhov zoo ntawm lub cev muaj zog, tus nqi me dua. Lub zog muaj peev xwm hais txog lub zog kom kov yeej kev sib txhuam, qhov inertia ntawm lub rotor nws tus kheej thiab lub zog tig lub zog ntawm lub rotor nws tus kheej. Feem ntau, thaum qhov ceev yog qhov tseeb, lub zog inertial ntawm lub rotor nce yuav luag tsis muaj, thiab lub zog muaj peev xwm tsuas yog kov yeej qhov teeb meem ntawm kev sib txhuam, thiab thaum kawg dissipated nyob rau hauv daim ntawv ntawm tshav kub zog, yog li qhov me me tsis muaj load tam sim no, qhov zoo dua. kev ua tau zoo ntawm lub cev muaj zog.

2. Rated tam sim no ntawm lub cev muaj zog ntawm rated voltage.

3. Pib tam sim no Qhov tam sim no thaum lub cev muaj zog pib ntawm qhov ntsuas hluav taws xob thiab qhov ntsuas zaus feem ntau yog ob peb zaug ntawm qhov ntsuas tam sim no. Loj pib tam sim no yuav ua rau qhov hloov pauv ntawm lub zog hluav taws xob network voltage thiab cuam tshuam rau kev siv cov khoom siv hluav taws xob ib txwm muaj. Qhov kev ntsuas no tseem ceeb dua, thiab qhov inertia ntawm lub rotor yog ntau dua qhov no. Lub cev muaj zog zoo muaj qhov me me pib tam sim no ntawm tib lub acceleration.

4. Qhov siab tshaj plaws nruam tam sim no yog hais txog qhov tshwm sim tam sim no thaum muaj kev rov qab los ntawm sab nraud (yog tias muaj qhov load). Cov khoom lag luam siab tshaj plaws tam sim no thiab cov khoom siv hluav taws xob tsawg dua li qhov ntsuas lub zog, tsis yog hais tias lub cev muaj zog yog qhov poob qis, tab sis lub sijhawm ntev nyob rau hauv cov xwm txheej loj tam sim no xws li ntsuas hluav taws xob, tuaj yeem ua rau kub siab, qhov cuam tshuam ncaj qha yog kev tiv thaiv nce. , efficiency, thiab ua rau poob ntawm tag nrho cov kev ua tau zoo, thiab tej zaum yuav ua rau cov khoom puas. Ua haujlwm ntawm tus nqi no, feem ntau tuaj yeem ua kom muaj kev ua haujlwm zoo rau lub sijhawm ntev.

 

Hwj chim

1. Rated zog hais txog lub zog zoo tshaj plaws ntawm lub cev muaj zog tsim, uas tseem yog lub zog siab tshaj plaws raws li kev pom zoo ua haujlwm. Rated zog yog ib qho tseem ceeb Performance index los sawv cev lub peev xwm ua hauj lwm ntawm lub cev muaj zog. Qhov piv ntawm cov zis hluav taws xob rau lub zog input yog qhia los ntawm feem pua. Qhov ntau dua qhov ua tau zoo, ntau dua qhov kev txuag hluav taws xob.

2. Maximum tso zis zog Maximum tso zis hwj chim ntawm qhov ntsuas voltage. Muaj qhov sib txawv ntawm lub zog no thiab lub zog ntsuas. Lub hwj chim no feem ntau tsis suav tias yog kev nyab xeeb, thiab nws tsis yog tus nqi uas tuaj yeem tswj tau ntev, tab sis feem ntau ntsuas ntawm 25 degrees ntawm chav tsev kub. Rated voltage, tam sim no thiab lub zog yog qhov tseem ceeb tshaj plaws ntawm lub cev muaj zog. Peb qhov kev sib raug zoo yog: fais fab=voltage x tam sim no (P=UI).

 

 

Ceev

1. Rated ceev ceev chav tsev yog RPM "rpm", nyob rau hauv feeb, ceev zaus hloov dua siab tshiab yuav tsum tau muab sau tseg. Rated ceev yog hais txog qhov ceev ntawm ib feeb thaum lub cev muaj zog ua haujlwm ntawm qhov ntsuas hluav taws xob, muaj peev xwm thiab zaus, uas yog, lub cev muaj zog ntawm kev thauj khoom tag nrho, yog li nws tseem hu ua kev thauj khoom ceev. Piv txwv li, ib tug 4- ncej lub cev muaj zog yog cim ntawm 1,450 rpm. Qhov sib txawv synchronous ceev yog 1500 RPM. Thaum cov zaus hloov pauv thiab lub cev muaj zog txo qis, qhov kev khiav haujlwm tam sim no yuav tsum raug txo kom tswj tau qhov cua thiab qhov kub ntawm qhov sib npaug.

2. Tsis muaj-load ceev Vim tias tsis muaj qhov rov qab torque, qhov tso zis hluav taws xob txawv ntawm qhov thaiv kev sib hloov. Qhov kev ntsuas no tsuas yog muab kev ua haujlwm ntawm lub cev muaj zog ntawm qhov siab tshaj plaws ntawm qhov ntsuas hluav taws xob.

3. Qhov siab tshaj plaws Qhov siab tshaj plaws kev sib hloov ceev yog qhov siab tshaj plaws kev sib hloov ceev ntawm lub cev muaj zog uas tuaj yeem ua tiav yam tsis xav txog lub zog thiab lub zog tso zis. Qhov parameter no muaj txiaj ntsig zoo rau kev ua tus yam ntxwv ntawm qhov nrawm thiab tus qauv tsim kev sib txuam.

 

Torque

1. Rated torque torque yog ib hom torque, torque hauv physics txhais tau tias: torque=quab yuam caj npab, ntawm no lub caj npab quab yuam tuaj yeem suav tias yog lub voj voog ntawm kev sib hloov ntawm cov khoom uas tau tsav los ntawm lub cev muaj zog. Yog hais tias lub torque ntawm lub cev muaj zog me me dhau, nws tsis tuaj yeem nqa cov khoom coj mus, uas yog, "lub zog" ntawm lub cev muaj zog tsis loj txaus. Rated torque=ntsuas lub zog / ntsuas nrawm * Torque tas li (9550). 2. Thaiv torque Qhov kev ntsuas no yog qhov tseem ceeb rau ntau lub cev muaj zog nrog kev thauj khoom, uas yog, lub zog torque thaum lub cev muaj zog nres rotating los ntawm lub zog sab nraud. Yog hais tias lub cev muaj zog thaiv qhov tshwm sim feem ntau tshwm sim, nws yuav ua rau lub cev muaj zog, los yog hlawv tawm cov tsav nti, yog li qhov no yog nyob rau hauv kev xaiv lub cev muaj zog, ntxiv rau qhov ceev, thawj qhov yuav tsum tau xav txog thawj qhov ntsuas. Nws chav tsev muaj nyuj nplej NM, kg nplej KG.M. Thov nco ntsoov tias rau lub sijhawm ntev, lub cev muaj zog kub nce sai, thiab tus nqi no tseem yuav poob sai.

2. Qhov siab tshaj plaws torque sawv cev rau lub cev muaj zog tuaj yeem txav tau qhov siab tshaj plaws load peev xwm, kuj yog sawv cev los ntawm qhov ntsuas torque ntau, feem ntau hauv 1.8-2.9 zaug (1.8-2.2 zaug) nws lub luag haujlwm , lub cev muaj zog kev sib hloov nyob rau hauv ib txwm ua hauj lwm, txhua yam yuav tshwm sim lub sij hawm luv luv ntawm load, yuav tsum tau lub cev muaj zog nyob rau hauv ib tug luv luv lub sij hawm, thiab tig los yog tig.

 

Cov saum toj no yog qee qhov kev paub txog kev paub txog qhov tseem ceeb ntawm micro motors los ntawm VSD Motors. Yog xav paub ntxiv, thov hu rau peb.
