Qhov txawv ntawm lub cev muaj zog brushed thiab brushless yog dab tsi?

Cov tshuab hluav taws xob tsis txhuam thiab cov tshuab hluav taws xob txhuam muaj tib lub hom phiaj tseem ceeb ntawm kev hloov cov hluav taws xob mus rau hauv kev txav mus los.

Cov cav uas siv txhuam tau muaj nyob rau ntau tshaj ib puas xyoo, thaum cov cav uas tsis siv txhuam tau tshwm sim hauv xyoo 1960 nrog kev tsim cov khoom siv hluav taws xob uas ua rau lawv tsim tau. Txawm li cas los xij, nws tsis yog txog thaum xyoo 1980 uas cov cav uas tsis siv txhuam tau pib tau txais kev lees paub dav dua hauv ntau yam cuab yeej thiab khoom siv hluav taws xob. Niaj hnub no, ob qho tib si txhuam thiab txhuam tau siv thoob ntiaj teb rau ntau daim ntawv thov.

Kev Sib Piv Txog Kev Siv Tshuab

Lub cev muaj zog txhuamua haujlwm los ntawm kev siv cov txhuam carbon uas sib cuag nrog lub commutator los xa cov hluav taws xob mus rau lub rotor, uas muaj cov hlau nplaum hluav taws xob. Qhov hluav taws xob ua rau muaj lub teb hluav taws xob hauv lub rotor, ua rau muaj kev txav mus los vim yog qhov sib hloov tas li ntawm qhov polarity ntawm lub zog rub hlau nplaum.

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

1. Lub neej luv luv: Cov cav txhuam muaj lub neej luv dua vim yog kev hnav thiab tsim kua muag ntawm cov txhuam thiab commutator.

2 Kev ua haujlwm qis dua: Cov cav txhuam muaj kev ua haujlwm qis dua piv rau cov cav txhuam tsis txhuam. Cov txhuam thiab cov commutator ua rau lub zog poob thiab poob hluav taws xob, ua rau muaj cua sov ntau dua.

3. Kev txwv ceev: Vim yog lub cev muaj zog ntawm cov txhuam thiab cov commutators, cov brushed motors muaj kev txwv rau kev siv ceev ceev. Kev sib txhuam ntawm cov txhuam thiab commutator txwv tsis pub lub zog ceev tshaj plaws ntawm cov brushed motors, txwv lawv txoj kev siv thiab kev ua haujlwm hauv qee qhov kev siv.

Lub tshuab tsis txhuam yog ib qholub cev muaj zog hluav taws xobuas ua haujlwm yam tsis siv txhuam thiab lub commutator. Hloov chaw, nws vam khom cov tswj hwm hluav taws xob thiab cov sensors los tswj lub zog xa mus rau lub cev muaj zog cov windings ncaj qha.

Muaj ob peb qhov tsis zoo ntawm brushless tsim:

1. Tus nqi siab dua: Cov cav tsis txhuam feem ntau kim dua li cov cav txhuam vim lawv cov qauv tsim thiab kev tswj hwm nyuaj dua.

2. Kev nyuaj ntawm hluav taws xob: Cov cav tsis txhuam hniav muaj cov txheej txheem tswj hluav taws xob nyuaj uas xav tau kev paub tshwj xeeb rau kev kho thiab txij nkawm.

3. Lub zog torque tsawg thaum lub zog qeeb: Cov cav tsis txhuam yuav muaj lub zog torque qis dua thaum lub zog qeeb piv rau cov cav txhuam. Qhov no tuaj yeem txwv lawv qhov kev tsim nyog rau qee qhov kev siv uas xav tau lub zog torque ntau thaum lub zog qeeb.

Qhov twg zoo dua: Txhuam los yog Brushless?

Ob qho tib si brushed thiab brushless lub cev muaj lawv cov txiaj ntsig.Cov cav txhuam pheej yig dua vim lawv cov khoom loj.

Ntxiv rau tus nqi, cov cav brushed muaj lawv cov txiaj ntsig uas tsim nyog xav txog:

1. Yooj Yim: Cov cav txhuam muaj tus qauv yooj yim dua, ua rau lawv yooj yim dua rau kev nkag siab thiab ua haujlwm nrog. Qhov yooj yim no kuj tseem tuaj yeem ua rau lawv yooj yim dua rau kev kho yog tias muaj teeb meem tshwm sim.

2. Muaj ntau yam siv: Cov cav txhuam tau muaj ntev heev thiab muaj ntau yam siv hauv kev ua lag luam. Qhov no txhais tau tias kev nrhiav cov khoom hloov lossis cov khoom seem rau kev kho feem ntau yooj yim dua.

3. Kev tswj ceev yooj yim: Cov cav txhuam muaj lub tshuab tswj yooj yim uas tso cai rau kev tswj ceev yooj yim. Kev kho qhov hluav taws xob lossis siv cov khoom siv hluav taws xob yooj yim tuaj yeem tswj qhov ceev ntawm lub cav.

Yog tias xav tau kev tswj hwm ntau dua, ib qho lub cev muaj zog tsis txhuam tej zaum yuav yog qhov kev xaiv zoo tshaj plaws rau koj daim ntawv thov.

Qhov zoo ntawm brushless yog:

1. Kev ua haujlwm zoo dua: Cov cav tsis txhuam tsis muaj cov commutators uas tuaj yeem ua rau muaj kev sib txhuam thiab poob zog, ua rau muaj kev hloov pauv zog zoo dua thiab tsis muaj cua sov pov tseg.

2. Lub neej ntev dua: Vim tias Brushless motors tsis muaj txhuam uas hnav tawm raws sijhawm kom ua rau muaj kev ruaj khov thiab lub neej ntev dua.

3. Qhov sib piv ntawm lub zog thiab qhov hnyav siab dua: Cov cav tsis txhuam muaj qhov sib piv ntawm lub zog thiab qhov hnyav siab dua. Qhov no txhais tau tias lawv tuaj yeem xa hluav taws xob ntau dua rau lawv qhov loj thiab qhov hnyav.

4. Ua haujlwm ntsiag to dua: Cov cav tsis txhuam tsis tsim suab nrov hluav taws xob thiab kev co tshuab. Qhov no ua rau lawv haum rau cov ntawv thov uas xav tau suab nrov qis, xws li cov khoom siv kho mob lossis cov khoom siv kaw suab.
