Dab tsi yog qhov txawv ntawm lub tshuab txhuam txhuam thiab txhuam tsis txhuam?

Brushless thiab brushed motors muaj tib lub hom phiaj tseem ceeb ntawm kev hloov hluav taws xob tam sim no rau hauv kev sib hloov.

Brushed motors tau nyob ib ncig ntawm ib puas xyoo, thaum brushless motors tshwm sim nyob rau hauv 1960s nrog kev loj hlob ntawm solid-state electronics uas enabled lawv tsim. Txawm li cas los xij, nws tsis yog txog thaum xyoo 1980 uas brushless motors pib tau txais kev pom zoo hauv ntau yam cuab yeej thiab hluav taws xob. Niaj hnub no, ob qho tib si brushed thiab brushless motors tau siv thoob ntiaj teb rau suav tsis txheeb.

Mechanical Comparation

Lub cev muaj zog txhuamua hauj lwm los ntawm kev siv cov pa roj carbon txhuam nyob rau hauv kev sib cuag nrog lub commutator kom hloov hluav taws xob voltage rau lub rotor, uas muaj electromagnets. Qhov voltage nyob rau hauv lem generates ib tug electromagnetic teb nyob rau hauv lub rotor, uas ua rau rotational motion raws li ib tug tshwm sim ntawm tsis tu ncua flipping lub polarity ntawm lub magnetic rub.

Txawm li cas los xij, cov qauv yooj yim, tab sis muaj qee qhov tsis zoo:

1. Tsawg lifespan: txhuam motors muaj ib tug luv luv lifespan vim yog hnav thiab tsim kua muag ntawm cov txhuam hniav thiab commutator.

2 Kev ua haujlwm qis dua: Cov tshuab txhuam txhuam muaj qhov ua haujlwm qis dua piv rau cov tshuab tsis txhuam. Cov txhuam hniav thiab cov commutator ua rau lub zog poob thiab hluav taws xob tam sim no poob, ua rau muaj hluav taws kub ntau dua.

3. Kev txwv ceev: Vim lub cev qauv ntawm cov txhuam hniav thiab cov commutators, txhuam lub cev muaj zog muaj kev txwv rau kev siv ceev ceev. Kev sib txhuam ntawm cov txhuam hniav thiab cov commutator txwv lub peev xwm ceev tshaj plaws ntawm txhuam cov motors, txwv tsis pub lawv siv thiab ua haujlwm hauv qee yam kev siv.

Lub cev muaj zog brushless yog ibhluav taws xob vibration motoruas ua haujlwm yam tsis muaj kev siv cov txhuam hniav thiab cov commutator. Hloov chaw, nws tso siab rau cov tswj hluav taws xob thiab cov sensors los tswj lub zog xa mus rau lub cev muaj zog windings ncaj qha.

Muaj ob peb qhov tsis zoo ntawm cov qauv siv brushless:

1. Tus nqi siab dua: Brushless motors feem ntau kim dua li txhuam cov motors vim lawv txoj kev tsim thiab kev tswj xyuas ntau dua.

2. Electronic complexity: Brushless motors koom nrog txoj kev tswj hluav taws xob uas xav tau kev paub tshwj xeeb rau kev kho thiab tu.

3. Txwv torque ntawm qis ceev: Brushless motors tej zaum yuav muaj zog torque nyob rau hauv qis dua piv rau brushed motors. Qhov no tuaj yeem txwv lawv qhov tsim nyog rau qee yam kev siv uas yuav tsum tau muaj qhov siab ntawm lub zog ntawm qhov nrawm.

Dab tsi yog qhov zoo dua: Txhuam lossis Txhuam Txhuam?

Ob leeg txhuam thiab txhuam tsis siv lub cev muaj zog muaj lawv cov txiaj ntsig.Txhuam motors yog pheej yig dua vim lawv cov khoom loj.

Ntxiv rau tus nqi, brushed motors muaj lawv tus kheej zoo uas tsim nyog xav txog:

1. Simplicity: Brushed motors muaj ib tug yooj yim tsim, ua rau lawv yooj yim to taub thiab ua hauj lwm nrog. Qhov kev yooj yim no tuaj yeem ua rau lawv yooj yim kho yog tias muaj teeb meem tshwm sim.

2. Muaj dav: Txhuam cov cav tov tau nyob ib ncig ntawm lub sijhawm ntev thiab muaj dav hauv khw. Qhov no txhais tau hais tias nrhiav kev hloov lossis cov khoom seem rau kev kho feem ntau yooj yim dua.

3. Kev tswj ceev ceev yooj yim: txhuam lub cev muaj zog muaj kev tswj xyuas yooj yim uas tso cai rau kev tswj ceev ceev. Kho qhov voltage lossis siv cov khoom siv hluav taws xob yooj yim tuaj yeem tswj xyuas qhov ceev ntawm lub cev muaj zog.

Nyob rau hauv rooj plaub uas yuav tsum tau tswj ntau dua, a brushless lub cev muaj zog tuaj yeem ua pov thawj yog qhov kev xaiv zoo tshaj rau koj daim ntawv thov.

Qhov zoo ntawm brushless yog:

1. Kev ua tau zoo dua: Cov tshuab txhuam txhuam tsis muaj qhov sib txuas uas tuaj yeem ua rau kev sib txhuam thiab lub zog poob, ua rau kev hloov pauv ntawm lub zog zoo dua qub thiab tsis tshua muaj cua sov.

2. Lub neej ntev dua: Txij li Brushless motors tsis muaj cov txhuam hniav uas hnav thaum lub sijhawm ua kom muaj zog thiab ua haujlwm ntev.

3. Ntau zog-rau-hnyav piv: brushless motors muaj ib tug ntau zog-rau-hnyav piv. Nws txhais tau tias lawv tuaj yeem xa ntau lub zog rau lawv qhov loj thiab qhov hnyav.

4. Kev ua haujlwm ntsiag to: brushless motors tsis tsim cov suab nrov ntawm hluav taws xob thiab cov neeg kho tshuab kev co. Qhov no ua rau lawv haum rau cov ntawv thov uas xav tau cov suab nrov qis, xws li cov cuab yeej kho mob lossis cov cuab yeej kaw.
