Classification ntawm Coreless Motors

I. Kev faib tawm ntawm Coreless Motors

Coreless motors tau muab faib ua ob hom: brushed thiab brushless. Brushed coreless motors muaj ib tug coreless rotor, thaum brushless coreless motors muaj ib tug coreless stator.

Brushed coreless motors siv ib tug spool thiab commutator li lub rotor, thaum brushless coreless motors siv ib tug spool li lub stator thiab mus tas li hlau nplaum raws li lub rotor.

II. Qhov sib txawv ntawm Brushed thiab Brushless Tsav

1. Txhuas Tsav

Brushed motors siv mechanical commutation; cov hlau nplaum nyob ruaj ruaj thaum lub coils tig. Thaum lub sijhawm ua haujlwm, cov coils thiab commutator tig, thaum cov hlau nplaum thiab cov txhuam hniav tsis ua haujlwm. Qhov kev hloov pauv hauv cov kev taw qhia ntawm lub kauj tam sim no yog ua tiav los ntawm kev sib hloov commutator thiab txhuam.

Nyob rau hauv ib lub cev muaj zog txhuam, cov txheej txheem yuav tsum tau npaj ob lub hwj chim input terminals ntawm txhua txheej coils nyob rau hauv ib lub nplhaib, sib cais los ntawm insulating cov ntaub ntawv, tsim ib tug cylindrical qauv integrated nrog lub cev muaj zog ncej. Lub zog yog nkag mus rau ib txheej ntawm coils los ntawm ob lub me me txhuam, uas, nyob rau hauv lub caij nplooj ntoos hlav siab, nias tawm tsam ob lub ntsiab lus ntawm lub kauj fais fab input nplhaib ntawm ob txoj haujlwm ruaj khov.

Raws li lub cev muaj zog rotates, sib txawv coils los yog sib txawv ncej ntawm tib lub kauj yog energized nyob rau hauv sib txawv lub sij hawm, tsim ib tug haum lub kaum sab xis sib txawv ntawm N-S ncej ntawm lub kauj generating nws magnetic teb thiab N-S ncej ntawm qhov ze tshaj plaws magnet stator. Lub attraction ntawm opposite sib nqus ncej thiab lub repulsion ntawm zoo li ncej tsim ib tug quab yuam uas tsav lub cev muaj zog. Cov pa roj carbon electrodes swb hla lub coil terminals, zoo li txhuam ntawm qhov chaw, yog li lub npe "carbon txhuam."

Qhov kev zawv zawg no ua rau muaj kev sib txhuam thiab hnav ntawm cov txhuam hniav, yuav tsum tau hloov lub sijhawm. Kev hloov pauv ntawm / tawm kev hloov pauv ntawm cov txhuam hniav thiab cov coil terminals tuaj yeem tsim cov hluav taws xob hluav taws xob, ua cov khoom siv hluav taws xob cuam tshuam uas tuaj yeem cuam tshuam cov khoom siv hluav taws xob.

2. Txhuam Txhuam Tsav

Brushless motors siv hluav taws xob commutation; cov coils nyob ruaj ruaj thaum cov hlau nplaum tig. Lub cev tsis muaj zog siv lub tshuab hluav taws xob uas, los ntawm Hall effect sensors, paub txog txoj haujlwm ntawm cov hlau nplaum ruaj khov. Raws li qhov kev paub no, hluav taws xob circuitry hloov cov kev taw qhia ntawm tam sim no nyob rau hauv lub coils raws sij hawm kom paub tseeb tias qhov tseeb sib nqus quab yuam yog generated los tsav lub cev muaj zog. Qhov no tshem tawm qhov tsis zoo ntawm txhuam cov motors.

Cov circuits no yog cov tswj lub cev muaj zog. Lub brushless lub cev muaj zog maub los kuj tseem ua tau haujlwm uas txhuam lub cev tsis tuaj yeem, xws li kho lub zog hloov lub kaum sab xis, nres lub cev muaj zog, thim rov qab lub cev muaj zog, xauv lub cev muaj zog, thiab nres lub zog rau lub cev muaj zog siv lub teeb liab braking. Lub tswb ntsuas hluav taws xob ntawm lub tsheb kauj vab hluav taws xob tam sim no siv tag nrho cov haujlwm no.

Brushless DC motors muaj lub cev muaj zog thiab tus tsav tsheb, thiab yog cov khoom siv mechatronic. Vim tias brushless DC motors ua haujlwm ntawm tus kheej - tswj hwm, lawv tsis tas yuav muaj kev pib winding ntawm lub rotor ntxiv xws li synchronous motors nyob rau hauv hnyav load pib nrog zaus conversion ceev tswj, lawv tsis muaj oscillations los yog poob ntawm synchronization thaum lub sij hawm tam sim ntawd load hloov.
