Qhov zoo thiab qhov tsis zoo ntawm Asynchronous thiab Synchronous Motors

Asynchronous motors thiab synchronous motors txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo ntawm cov yam ntxwv ntawm kev ceev, cov qauv kev ua haujlwm, kev ua haujlwm zoo, tus nqi, thiab daim ntawv thov scenarios: Asynchronous motors muaj cov qauv yooj yim, tus nqi qis, thiab pib yooj yim, tab sis lawv muaj lub zog qis thiab tsis ruaj khov; synchronous motors tswj qhov ceev tsis tu ncua, muaj kev ua haujlwm siab, thiab tso cai rau lub zog hloov tau, tab sis lawv muaj cov qauv nyuaj, tus nqi siab, thiab pib nyuaj.

Cov yam ntxwv ceev thiab txoj hauv kev ua haujlwm

1.Asynchronous lub cev muaj zog: Lub rotor ceev yog ib txwm qis dua lub stator rotating magnetic teb ceev (nrog rau tus nqi qis), cia siab rau electromagnetic induction los tsim torque, thiab qhov ceev hloov nrog lub load. cov

‌‌

2.Synchronous lub cev muaj zog: Lub rotor ceev yog nruj me ntsis synchronized nrog lub zog zaus (nrog xoom plam), uas tau tsav los ntawm magnetic teb coupling, thiab qhov ceev yog tas li tsis muaj kev cuam tshuam los ntawm lub load. cov

 

 

Kev ua tau zoo thiab Efficiency

1.Power yam:

Asynchronous motors muaj lub zog qis (feem ntau 0.7-0.9), uas tej zaum yuav poob qis dua 0.3 nyob rau hauv lub teeb load thiab yuav tsum tau reactive zog them.

‌‌

2.Synchronous motors muaj lub zog siab thiab kho tau zoo, uas tuaj yeem ua kom zoo dua los ntawm kev ua kom zoo dua tam sim no los txhim kho lub zog ntawm daim phiaj hluav taws xob. cov

3.Efficiency:

Asynchronous motors muaj kev ua haujlwm siab nyob ze ntawm qhov ntsuas load, tab sis lawv cov kev ua tau zoo txo ​​qis hauv lub teeb. cov

4.Synchronous motors (tshwj xeeb tshaj yog hom hlau nplaum tas mus li) feem ntau muaj kev ua haujlwm siab dua (txog 95% lossis ntau dua) thiab ua kom muaj kev ua haujlwm siab tshaj qhov dav dav. cov

4.Structure thiab nqi

Asynchronous lub cev muaj zog: qauv yooj yim, tsis muaj excitation system, tsawg raug nqi, yooj yim txij nkawm. cov

Synchronous lub cev muaj zog: complex qauv, yuav tsum tau excitation li (xws li plam rings los yog cov hlau nplaum tas mus li), tus nqi siab, thiab kev saib xyuas siab.

 

 

Qhov sib txawv ntawm asynchronous motor thiab synchronous motor

1, Asynchronous lub cev muaj zog

1.1 Lub hauv paus ntsiab lus ua haujlwm

Asynchronous lub cev muaj zog, tseem hu ua induction lub cev muaj zog, ua haujlwm los ntawm kev siv lub rotating magnetic teb generated los ntawm stator winding los txiav lub rotor winding, induce tam sim no, thiab yog li tsim torque. Lub rotor ceev yog qis dua li synchronous ceev, ua rau plam.

1.2 Hom Rotor

Lub rotors ntawm asynchronous motors feem ntau muab faib ua ob hom: squirrel tawb thiab lub qhov txhab rotor.

 

 

Squirrel tawb asynchronous motor

Nta: Cov qauv yooj yim, ruaj khov thiab ruaj khov, tus nqi qis, kev saib xyuas yooj yim.

Daim ntawv thov: dav siv hauv cov khoom siv xws li kiv cua, twj, compressors, thiab lwm yam.

 

 

Mob asynchronous lub cev muaj zog

Nta: Siab pib torque, haum rau hnyav- lub luag haujlwm pib, kev ua haujlwm tau zoo.

Daim Ntawv Thov: Siv nyob rau hauv cov xwm txheej uas yuav tsum tau pib lub zog siab, xws li nqa cov khoom siv thiab cov tshuab loj.

1.3 Qhov zoo thiab qhov tsis zoo

Qhov zoo:

Cov qauv yooj yim thiab cov nqi tsim khoom tsawg.

Txhim khu kev ua haujlwm thiab kev saib xyuas yooj yim.

Dav siv tau thiab adaptable heev.

Qhov tsis zoo:

Lub zog qhov tseem ceeb yog tsawg thiab sib txawv nrog cov load.

Kev tswj ceev ceev tsis zoo.

 

 

2, Synchronous lub cev muaj zog

2.1 Lub hauv paus ntsiab lus ua haujlwm

Lub rotor ntawm lub tshuab synchronous rotates synchronously nrog stator magnetic teb, uas yog, qhov ceev ntawm lub rotor yog tib yam li qhov ceev ntawm rotating magnetic teb generated los ntawm lub stator, tsis muaj ib tug plam.

2.2 Hom Rotor

Lub rotor ntawm synchronous lub cev muaj zog feem ntau muab faib ua hom hlau nplaum ruaj khov thiab hom hluav taws xob zoo siab.
