Lub luag haujlwm ntawm cov txhuam hniav hauv kev cuam tshuam cov laum motors

Lub luag haujlwm ntawm qhov cuam tshuam laum carbon txhuam yog xa cov excitation tam sim no generated los ntawm lub excitation generator mus rau lub rotor kauj. Lub hauv paus ntsiab lus ntawm kev cuam tshuam drilling hluav taws xob yog tias tom qab lub magnetic teb txiav cov hlau, ib tug tam sim no generated nyob rau hauv cov hlau. Lub tshuab hluav taws xob siv cov txheej txheem ntawm rotating magnetic teb los txiav cov hlau. Lub rotating magnetic teb yog lub rotor, thiab txiav hlau yog stator. Nyob rau hauv thiaj li yuav rotor los tsim ib qho chaw sib nqus, ib qho kev txhawb siab tam sim no yuav tsum tau nkag rau hauv coil ntawm lub rotor, thiab cov pa roj carbon txhuam ua lub luag haujlwm no.

Qhov tseeb, " txhuam" ntawm no hais txog rau carbon txhuam. Kev xyaum cuam tshuam feem ntau siv DC motors. Brushed Impact xyaum xyaum siv txhuam motors, uas yuav tsum tau commutated los ntawm txhuam. Cov pa roj carbon txhuam yog commutated los ntawm Hall sensor thiab tsav los ntawm tus tsav tsheb tig.

Piv nrog brushless kev xyaum xyaum, txhuam hniav feem ntau muaj cov nram qab no zoo thiab qhov tsis zoo:

Qhov zoo: Cov txhuam txhuam txhuam pib pib ceev ceev, brakes raws sij hawm, smooth ceev tswj, yooj yim tswj, yooj yim qauv, pheej yig tus nqi, thiab nws muaj ib tug loj pib tam sim no, loj torque (kev sib hloov quab yuam) ntawm qhov ceev ceev, thiab tuaj yeem nqa lub nra hnyav.

Disadvantages: Vim muaj kev sib txhuam ntawm cov pa roj carbon txhuam thiab cov commutator, qhov cuam tshuam nrog cov txhuam hniav yog nquag sparks, tshav kub, suab nrov, electromagnetic cuam tshuam rau sab nraud ib puag ncig, thiab tsis tshua muaj efficiency thiab lub neej luv luv; carbon txhuam yog consumables, tom qab ib lub sij hawm ntawm lub sijhawm, nws yuav raug hloov, uas yog teeb meem.
