DC txhuamLub cev muaj zog yog ib hom lub cev muaj zog uas siv hluav taws xob ncaj qha (DC). Lawv siv rau ntau yam kev siv, txij li cov khoom siv hluav taws xob me me mus rau cov tshuab loj hauv kev lag luam. Hauv tsab xov xwm luv luv no, peb yuav saib ze dua seb cov brushed DC motors ua haujlwm li cas, lawv cov khoom sib xyaw, thiab lawv cov ntawv thov.
Kev ua haujlwm yooj yim ntawm ib qhoLub cev muaj zog haptic 8 hli txoj kab uas hlacuam tshuam nrog kev sib cuam tshuam ntawm lub zog sib nqus thiab hluav taws xob tam sim no los tsim kev txav mus los. Cov khoom tseem ceeb ntawm lub cev muaj zog DC brushed suav nrog stator, rotor, commutator thiab txhuam. Lub stator yog qhov chaw ruaj khov ntawm lub cev muaj zog thiab muaj cov hlau nplaum lossis cov kauj hluav taws xob hauv nws, thaum lub rotor yog qhov tig ntawm lub cev muaj zog thiab muaj lub armature. Lub commutator yog lub qhov hloov pauv rotary uas tswj cov dej ntws ntawm tam sim no mus rau lub armature, thiab txhuam kov lub commutator kom hloov lub zog mus rau lub armature.
Thaum muaj hluav taws xob siv rau lub cev muaj zog, lub zog sib nqus yuav tsim nyob rau hauv lub stator. Lub zog sib nqus no cuam tshuam nrog lub zog sib nqus ntawm lub rotor, ua rau lub rotor tig. Thaum lub rotor tig, lub commutator thiab cov txhuam ua haujlwm ua ke los hloov pauv qhov kev taw qhia ntawm cov hluav taws xob ntws los ntawm lub armature kom ntseeg tau tias lub rotor txuas ntxiv tig mus rau tib qho kev taw qhia.
Txoj Cai Ua Haujlwm
Kev ua haujlwm ntawm lub tshuab hluav taws xob DC brushed yog lub hauv paus ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction thiab kev sib cuam tshuam ntawm cov teb magnetic. Thaum cov hluav taws xob raug muab rau lub tshuab, lub stator - txawm tias nruab nrog cov hlau nplaum tas mus li lossis cov kauj hlau nplaum - tsim kom muaj lub teb magnetic ruaj khov. Tib lub sijhawm, cov hluav taws xob ntws los ntawm cov armature windings ntawm lub rotor, hloov lub rotor mus rau hauv lub electromagnet. Lub teb magnetic ntawm lub stator thiab lub teb magnetic ntawm lub rotor sib cuam tshuam nrog ib leeg, tsim cov torque rotational (Lorentz force) uas ua rau lub rotor tig.
Ib qho tseem ceeb ntawm kev ua kom lub commutator thiab txhuam tig mus rau tib qho kev taw qhia yog kev koom tes ntawm lub commutator thiab txhuam. Thaum lub rotor tig, lub commutator - ib qho khoom sib cais-ring txuas rau lub rotor ncej - tig ua ke. Cov txhuam, feem ntau yog ua los ntawm carbon lossis graphite, tswj kev sib cuag tas li nrog cov ntu commutator. Thaum lub rotor mus txog qhov chaw tshwj xeeb, lub commutator hloov qhov kev taw qhia ntawm cov hluav taws xob ntws los ntawm cov armature windings. Qhov kev tig rov qab ntawm cov hluav taws xob no ua kom ntseeg tau tias lub magnetic polarity ntawm lub rotor piv rau stator tseem sib xws, tsim kom muaj lub zog tig mus tas li thiab tiv thaiv lub rotor los ntawm stalling lossis thim rov qab kev taw qhia.
Cov yam ntxwv ntawm kev ua tau zoo
Kev Ua Haujlwm Zoo
Qhov ua tau zoo ntawm cov brushed DC motors sib txawv nyob ntawm lawv tus qauv tsim, qhov loj me, thiab cov xwm txheej ua haujlwm. Cov brushed DC motors me dua, xws li cov uas siv rau hauv cov khoom siv hluav taws xob, feem ntau muaj qhov ua tau zoo ntawm 50-70%, thaum cov motors loj dua rau kev lag luam tuaj yeem ua tau zoo txog li 85% lossis siab dua. Cov yam tseem ceeb uas cuam tshuam rau qhov ua tau zoo suav nrog kev sib txhuam ntawm txhuam-commutator, kev poob tooj liab hauv cov armature windings, kev poob hlau hauv stator thiab rotor cores, thiab kev poob tshuab (piv txwv li, kev sib txhuam ntawm cov kabmob). Kev hnav txhuam thiab kev puas tsuaj ntawm commutator dhau sijhawm kuj tuaj yeem ua rau kev ua tau zoo qeeb qeeb.
Kev ruaj khov thiab lub neej ntev
Lub neej ntawm lub tshuab hluav taws xob DC brushed feem ntau yog txiav txim siab los ntawm kev hnav ntawm txhuam thiab commutator. Hauv cov xwm txheej ua haujlwm ib txwm, cov txhuam tuaj yeem kav ntev li ob peb txhiab txog kaum txhiab teev, nyob ntawm cov yam xws li kev ua haujlwm ceev, kev thauj khoom, kub, thiab qhov zoo ntawm cov txhuam thiab cov khoom siv commutator. Hauv kev siv ceev lossis kev thauj khoom siab, kev hnav ntawm txhuam raug ua kom nrawm dua, txo lub neej ntawm lub tshuab. Tsis tas li ntawd, kev sib txhuam ntawm cov txhuam thiab commutator tsim cov hmoov av thiab cua sov, uas tuaj yeem cuam tshuam rau kev ua haujlwm thiab kev ruaj khov ntawm lub tshuab yog tias tsis tswj hwm kom zoo.
