Brushless vs Brushed Vibration Motors: Qhov Twg Yog Qhov Zoo Rau Koj Lub Tshuab?

Thaum xaiv cov cav co rau cov khoom siv me me, qhov kev xaiv ntawm cov cav BLDC me me (5mm-12mm txoj kab uas hla) thiab cov cav txhuam me me (7mm-12mm txoj kab uas hla) tuaj yeem txhais cov khoom ua haujlwm, lub neej ntev, thiab kev paub ntawm tus neeg siv. Ob leeg hloov lub zog hluav taws xob mus rau hauv kev txav mus los kom tsim kev co, tab sis lawv qhov kev tsim qauv sib txawv tsim cov txiaj ntsig sib txawv rau cov ntawv thov tshwj xeeb. Hauv qab no yog kev sib piv kom ua rau koj qhov kev txiav txim siab - ntxiv rau kev nkag siab txog peb cov kev daws teeb meem cav.

Qhov Sib Txawv ntawm Cov Qauv Tseem Ceeb

Qhov sib txawv tseem ceeb yog nyob rau hauv txhua lub cev muaj zog ua tiav kev sib hloov (kev tswj hwm kev taw qhia tam sim no), uas cuam tshuam rau kev ruaj khov, kev ua haujlwm zoo, thiab qhov nyuaj.

Micro Brushless Motors(5mm-12mm)

Cov motors no tshem tawm cov txhuam carbon thiab cov khoom siv commutator uas pom muaj nyob rau hauv cov qauv tsim ib txwm muaj. Hloov chaw, lawv vam khom cov khoom siv hluav taws xob thiab Hall sensors los tswj cov dej ntws mus rau stator windings. Cov yam ntxwv tseem ceeb ntawm cov qauv muaj xws li:

• Kev teeb tsa Stator-rotor: Ib lub stator ruaj khov nrog cov hlau nplaum tas mus li thiab lub rotor uas tig los ntawm lub kauj (lossis rov ua dua hauv qee qhov qauv).

• Cov khoom siv hluav taws xob sib xyaw ua ke: Ntau lub tshuab BLDC me me muaj cov IC tsav tsheb, ua kom yooj yim rau kev sib koom ua ke nrog cov PCBs yam tsis muaj kev cuam tshuam hluav taws xob.

• Kev txhim kho cov khoom siv: Cov hlau nplaum Nd-Fe-B ua haujlwm tau zoo thiab cov plhaub txhuas ua rau lub zog ceev thiab cua sov ploj mus.

Tus qauv tsis txhuam tsis pub kov lub cev ntawm cov khoom txav mus los, txo kev sib txhuam thiab kev hnav - qhov kev hloov pauv rau kev ntseeg tau mus sij hawm ntev.

Cov Tsav Tsheb Txhuam Me Me(7mm-12mm)

Ib lub tshuab uas muaj hnub nyoog ib puas xyoo, cov motors no siv lub tshuab yooj yim:

• Cov txhuam carbon + commutator: Cov txhuam xa cov hluav taws xob mus rau lub rotor lub electromagnets los ntawm kev swb mus rau ntawm lub commutator uas tau muab faib ua ntu, uas tig cov hluav taws xob mus rau qhov kev taw qhia kom tswj tau kev sib hloov.

• Kev tsim kho yooj yim: Cov khoom tsawg dua (tsis muaj cov sensors lossis cov maub los) txo cov nqi tsim khoom tab sis txwv kev ua haujlwm.

• Cov qauv tseem ceeb: Qee lub tshuab txhuam hniav muaj cov qauv rotor tsis muaj qhov tseem ceeb (cov kauj zoo li khob) kom txo qhov inertia, txawm hais tias lawv tseem vam khom cov txhuam hlau muaj nqis rau kev hloov pauv.

Txawm hais tias pheej yig los, qhov sib txuas ntawm txhuam-commutator tsim cov kev txwv hauv lub neej thiab kev ua haujlwm zoo.

Kev Sib Piv Qhov Loj & Daim Ntawv Qhia

Ob hom cav sib txawv rau cov ntawv thov me me, tab sis lawv qhov loj me thiab kev tsim qauv sib txawv:
