Kev taw qhia ntawm brushless DC lub cev muaj zog hauv cov cuab yeej hluav taws xob

Nrog kev txhim kho ntawm cov roj teeb tshiab thiab cov thev naus laus zis tswj hwm hluav taws xob, tus nqi tsim thiab tsim khoom ntawm brushless DC lub cev muaj zog tau raug txo qis heev, thiab cov cuab yeej yooj yim uas xav tau brushless DC lub cev muaj zog tau nrov thiab siv dav dua. Nws yog siv dav hauv kev lag luam tsim khoom, sib dhos thiab txij nkawm, tshwj xeeb tshaj yog nrog kev txhim kho kev lag luam, qhov kev thov rau tsev neeg kuj tau nce siab thiab siab dua, thiab tus nqi loj hlob txhua xyoo yog siab dua li lwm yam lag luam.

2, yooj yim rechargeable hluav taws xob cuab yeej lub cev muaj zog daim ntawv thov hom

2.1 Lub cev muaj zog txhuam DC

Cov qauv ntawm lub cev muaj zog DC brushless suav nrog rotor (ncej, hlau core, winding, commutator, bearing), stator (casing, magnet, end cap, thiab lwm yam), carbon brush sib dhos, carbon brush caj npab thiab lwm yam.

Txoj Cai Ua Haujlwm: Lub stator ntawm lub cev muaj zog DC brushed tau teeb tsa nrog lub ncej tseem ceeb (magnet) thiab txhuam, thiab lub rotor tau teeb tsa nrog armature winding thiab commutator. Lub zog hluav taws xob ntawm lub zog fais fab DC nkag mus rau hauv armature winding los ntawm cov txhuam carbon thiab commutator, tsim cov armature tam sim no. Lub teb sib nqus uas tsim los ntawm armature tam sim no cuam tshuam nrog lub teb sib nqus tseem ceeb los tsim cov electromagnetic torque, uas ua rau lub cev muaj zog tig thiab tsav lub nra hnyav.

Qhov Tsis Zoo: Vim muaj cov txhuam carbon thiab commutator, kev ntseeg tau ntawm lub cev muaj zog txhuam tsis zoo, tsis ua haujlwm, tam sim no tsis ruaj khov, lub neej luv luv, thiab lub zog hluav taws xob commutator yuav tsim kev cuam tshuam electromagnetic.

2.2 Lub cev muaj zog DC tsis txhuam

Cov qauv ntawm lub cev muaj zog DC brushless suav nrog lub cev muaj zog rotor (ncej, hlau core, hlau nplaum, bearing), stator (casing, hlau core, winding, sensor, kawg npog, thiab lwm yam) thiab cov khoom tswj.

Txoj Cai Ua Haujlwm: Lub cev muaj zog DC brushless muaj lub cev muaj zog thiab tus tsav tsheb, yog cov khoom siv mechatronics ib txwm muaj. Txoj cai ua haujlwm zoo ib yam li lub cev muaj zog txhuam, tab sis cov commutator ib txwm muaj thiab cov txhuam carbon raug hloov los ntawm qhov chaw sensor thiab kab tswj, thiab qhov kev taw qhia ntawm tam sim no raug hloov los ntawm kev tswj hwm los ntawm lub teeb liab sensing kom ua tiav qhov kev hloov pauv, yog li kom ntseeg tau tias lub cev muaj zog electromagnetic torque thiab kev tsav tsheb tas li thiab ua rau lub cev muaj zog tig.

3. Cov txiaj ntsig thiab qhov tsis zoo ntawm BLDC lub cev muaj zog daim ntawv thov

3.1 Qhov zoo ntawm BLDC lub cev muaj zog:

3.1.1 Cov qauv yooj yim thiab zoo txhim khu kev qha:

Tshem tawm commutator, carbon txhuam, txhuam caj npab thiab lwm qhov, tsis muaj commutator vuam, ua tiav cov txheej txheem.

3.1.2 Lub neej ua haujlwm ntev:

Siv cov khoom siv hluav taws xob los hloov cov qauv commutator ib txwm muaj, tshem tawm lub cev muaj zog vim yog cov pa roj carbon txhuam thiab commutator commutator hluav taws xob, kev hnav khoom siv thiab lwm yam teeb meem uas tshwm sim los ntawm lub neej luv luv, lub neej ntawm lub cev muaj zog tau nce ntau.

3.1.3 Nyob ntsiag to thiab ua haujlwm tau zoo:

Tsis muaj cov txhuam carbon thiab cov qauv commutator, tsis txhob muaj lub txim hluav taws xob commutator thiab kev sib txhuam ntawm cov txhuam carbon thiab commutator, ua rau muaj suab nrov, cua sov, poob zog ntawm lub cev muaj zog, thiab txo qhov ua haujlwm ntawm lub cev muaj zog. Brushless DC lub cev muaj zog ua haujlwm tau 60 ~ 70%, thiab brushless DC lub cev muaj zog ua haujlwm tau 75 ~ 90%.

3.1.4 Kev tswj hwm ceev thiab kev tswj hwm dav dua:

Cov khoom siv hluav taws xob thiab cov sensors uas raug ntsuas tau tuaj yeem tswj tau qhov ceev ntawm cov zis, torque thiab qhov chaw ntawm lub cev muaj zog, ua kom paub tseeb tias ntse thiab ntau yam haujlwm.
