Cov Kev Cai Qhia Txog Kev Siv
Lub luag haujlwm ntawm cov txhuam carbon uas tau grounded hauv cov kab ke hluav taws xob yog qhov tseem ceeb rau ntau yam kev siv. Cov txhuam carbon yog qhov tseem ceeb rau kev ua kom cov motors ua haujlwm tau zoo thiab kev hloov pauv tam sim no zoo, ua haujlwm ua cov khoom tseem ceeb hauv ob qho tib si brushed thiab brushless DC motors, nrog rau cov hom AC motors tshwj xeeb.
Hauv cov brushed DC motors, cov txhuam carbon muaj ntau yam tseem ceeb. Feem ntau, lawv muab cov hluav taws xob sab nraud lossis cov hluav taws xob excitation rau lub rotor tig, ua haujlwm ua txoj hauv kev conductive, uas yog qhov tseem ceeb rau kev ua haujlwm ntawm lub cev muaj zog. Tsis tas li ntawd, cov txhuam carbon ua rau muaj hluav taws xob static rau ntawm lub rotor shaft, ua rau nws grounded zoo. Cov txhuam carbon grounded no ua rau cov hluav taws xob tso tawm yooj yim, txhawb kev ntws hluav taws xob tas li hauv lub cev. Nws kuj pab hloov qhov kev coj ntawm cov hluav taws xob, thiab hauv cov commutator motors, nws txhawb nqa cov txheej txheem commutation. Tsis tas li ntawd, cov txhuam txuas lub rotor shaft rau lub cuab yeej tiv thaiv rau lub hom phiaj grounding thiab ua rau muaj kev ntsuas ntawm cov hluav taws xob zoo thiab tsis zoo piv rau hauv av.
Lub commutator, uas muaj cov txhuam thiab cov nplhaib commutation, yog ib qho tseem ceeb hauv cov brushed DC motors. Vim yog lub rotor tig, lub txhuam yeej ib txwm muaj kev sib txhuam rau lub nplhaib commutation, uas tuaj yeem ua rau muaj hluav taws xob tawg thaum lub sijhawm commutation. Qhov kev hnav thiab kev puas tsuaj no suav tias cov txhuam carbon yog ib feem siv tau hauv DC motors. Txhawm rau kom txo tau cov teeb meem no, cov brushless DC motors tau tsim los ua lwm txoj hauv kev ruaj khov dua, lub hom phiaj yog txhim kho lub neej ua haujlwm, kev ruaj khov ua haujlwm, thiab txo qis suab nrov thiab kev cuam tshuam electromagnetic.
Nws yog ib qho tseem ceeb uas cov AC motors feem ntau tsis siv cov txhuam lossis lub commutator, vim lawv ua haujlwm yam tsis muaj lub zog sib nqus tas li. Txawm li cas los xij, AC motors feem ntau loj dua li lawv cov DC counterparts. Qhov sib txawv no qhia txog qhov tseem ceeb ntawm cov txhuam carbon hauv kev ua haujlwm ntawm DC motors thiab qhia txog kev nce qib hauv kev siv tshuab motor.
Hauv kev xaus lus, lub luag haujlwm ntawm cov txhuam carbon uas tau sib txuas ua ke yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm ntau hom cav. Raws li thev naus laus zis hloov zuj zus, qhov tseem ceeb ntawm cov txhuam carbon hauv cov kab ke hluav taws xob tseem yog qhov tseem ceeb hauv kev ua kom lub cev muaj zog ua haujlwm tau zoo thiab kev ntseeg tau.
