Qhov kev txav mus los no tsim kev co uas xa mus rau qhov chaw uas lawv tau teeb tsa, tsim kom muaj kev co lossis kev co.
Ib qho ntawm cov txiaj ntsig ntawm cov tshuab brushless yog tias lawv tsis muaj cov txhuam carbon, uas tshem tawm qhov teeb meem ntawm kev hnav dhau sijhawm, ua rau lawv txhim khu kev qha thiab ua haujlwm tau zoo.
Cov cav no muaj lub neej ua haujlwm ntev dua li cov cav txhuam nyiaj ib txwm muaj, feem ntau tsawg kawg yog 10 npaug ntev dua. Hauv hom kev sim uas lub cav ua haujlwm hauv lub voj voog ntawm 0.5 vib nas this thiab 0.5 vib nas this tawm, tag nrho lub neej tuaj yeem ncav cuag 1 lab zaug. Nws tsim nyog sau tseg tias cov cav tsis txhuam nrog cov tsav tsheb sib xyaw ua ke yuav tsum tsis txhob tsav rov qab, txwv tsis pub tus tsav tsheb IC yuav puas tsuaj. Nws raug pom zoo kom txuas cov hlau txuas ntawm lub cav los ntawm kev txuas lub zog zoo rau cov hlau liab (+) thiab lub zog tsis zoo rau cov hlau dub (-)
Lub cev muaj zog me me uas tsis muaj txhuam yog lub cev muaj zog me me uas tsis muaj txhuam ncaj qha (BLDC) uas tsim los rau cov ntawv thov uas qhov chaw, kev ua haujlwm zoo, thiab kev ruaj khov yog qhov tseem ceeb. Tsis zoo li cov cev muaj zog txhuam, nws tshem tawm cov txhuam lub cev, vam khom kev hloov pauv hluav taws xob. Cov cev muaj zog no tau tsim los kom me me (feem ntau nrog cov kab uas hla me li 5-12 hli) thaum xa cov kev ua tau zoo siab, ua rau lawv zoo tagnrho rau cov khoom siv xws li cov khoom hnav tau, cov cuab yeej kho mob, thiab cov khoom siv hluav taws xob me me.
Ib lub cev muaj zog BLDC me me ua haujlwm los ntawm kev sib hloov hluav taws xob (tsis muaj txhuam lub cev). Nov yog kev piav qhia yooj yim:
- Nws muaj ib lub stator (nrog rau cov xov tooj liab) thiab ib lub rotor (nrog cov hlau nplaum tas mus li).
- Ib lub maub los (tsav tsheb) xa cov teeb liab hluav taws xob mus rau cov stator windings, tsim kom muaj lub teb sib nqus tig.
- Lub zog sib nqus no cuam tshuam nrog lub rotor cov hlau nplaum tas mus li, ua rau lub rotor tig.
- Cov sensors (lossis cov algorithms tsis muaj sensor) ntes tau qhov chaw ntawm lub rotor, uas tso cai rau tus maub los kho qhov kev taw qhia tam sim no hauv cov stator windings - kom ntseeg tau tias kev sib hloov tas mus li thiab du.
Tus qauv tsim no tshem tawm kev hnav ntawm txhuam, ua rau lub neej ntev dua, ua haujlwm tau zoo dua, thiab ua haujlwm ntsiag to dua piv rau cov tshuab txhuam.
Lub tshuab hluav taws xob micro brushless vibration muaj cov qauv me me, tiaj tus, thiab ua kom zoo rau cov kev siv uas tsis muaj chaw ntau. Nws muaj cov hauv qab no:
- Stator: Ib lub rooj tsavxwm me me luam tawm (PCB) nrog cov xov tooj liab sib xyaw ua ke, tsim ib qho electromagnetic coil array.
- Rotor: Ib lub sib dhos zoo li npib nrog cov hlau nplaum tas mus li (feem ntau yog cov hlau nplaum tsis tshua muaj rau qhov ceev torque siab) thiab lub cev eccentric (los tsim kev co thaum tig).
- Lub Tshuab Hluav Taws Xob Sib Txuas Lus: Cov sensors ua ke (lossis cov algorithms tswj tsis muaj sensor) thiab lub voj voog tsav tsheb los tswj cov dej ntws hauv cov stator windings, tshem tawm cov txhuam lub cev.
Cov stator windings raug energized ua ntu zus los ntawm lub commutation system, tsim ib lub magnetic field rotating. Lub field no cuam tshuam nrog lub rotor cov permanent magnets, ua rau lub rotor (nrog nws lub eccentric mass) tig. Lub eccentric mass txoj kev tig tsis sib npaug tsim kev co - lub hauv paus mechanism rau haptic feedback lossis mechanical stimulation.
Yuav kom tsav lub dc brushless vibration motor, koj xav tau BLDC motor driver (controller) uas ua haujlwm peb txoj haujlwm tseem ceeb:
1. Kev Tshawb Pom Qhov Chaw Rotor: Tus tsav tsheb siv cov cuab yeej ntsuas qhov cuam tshuam (lossis cov algorithms tsis muaj sensor zoo li kev tshawb pom rov qab-EMF) los taug qab qhov chaw ntawm lub rotor.
2. Kev sib hloov: Raws li qhov chaw ntawm lub rotor, tus tsav tsheb hloov qhov kev taw qhia tam sim no hauv cov stator windings, tswj kom muaj lub zog sib nqus tig.
3. Kev Tswj Ceev/Kev Siv Zog: Los ntawm kev kho qhov hluav taws xob lossis tam sim no uas muab rau lub stator, tus tsav tsheb tswj qhov ceev ntawm lub cev muaj zog - yog li ntawd tswj qhov muaj zog ntawm kev co.
Rau kev koom ua ke, tus tsav tsheb txuas rau lub zog thiab cov teeb liab ntawm lub cev muaj zog (piv txwv li, FPCB connectors lossis cov xov hlau txhuas), thiab lub kaw lus tswj hwm tseem ceeb xa cov lus txib (piv txwv li, PWM teeb liab) rau tus tsav tsheb kom kho cov qauv kev co lossis qhov muaj zog.
