Txhuam DC ua haujlwm ua haujlwm
Lub tshuab tsis txhuam ntswj yog tsim los ntawm ib lub cev muaj zog thiab tus tsav tsheb, thiab yog ib qho khoom siv mechatronic. Lub stator windings ntawm lub cav yog feem ntau ua rau hauv ib qho kev ua qauv rau peb lub caij sib txuas, uas yog qhov sib npaug zoo li peb theem ntawm asynchronous lub cev. Ib qho magnetized tas li hlau nplaum yog adhered rau lub rotor ntawm lub cev, thiab ib txoj hauj lwm sensor mounted nyob rau hauv lub cev kom pom lub polarity ntawm lub rotor ntawm lub cev. Tus tsav tsheb yog tsim los ntawm cov hluav taws xob hluav taws xob thiab kev sib xyaw ua ke, thiab kev khiav haujlwm xws li: txais pib, nres, thiab nres cov paib ntawm lub tshuab kom pib, nres, thiab nres ntawm lub cev; tau txais txoj hauj lwm sensor tseg thiab xa thiab thim qhov teeb meem rau kev tswj qhov ntxig Cov hluav taws xob txuas ntawm qhov kev hloov tsheb tau tig rau thiab tawm los ua kom nruam torque; qhov hais kom ceev thiab cov lus ceeb toom ceev tau txais los tswj thiab kho qhov ceev; muab kev tiv thaiv thiab kev pom, thiab cov zoo li no.
DC motors muaj cov lus teb ceev ceev, pib lub tswv yim loj, thiab muaj peev xwm muab cov tswv yim taw los ntawm kev xoom ceev kom ceev npaum li cas. Txawm li cas los, qhov tsav ntawm DC motors kuj yog nws cov shortcomings, vim DC motors yuav tsum ua kom muaj kev sib hloov tas li raws li kev kwv yees. Rau qhov kev ua tau zoo ntawm lub caij no, lub armature magnetic field thiab rotor magnetic teb yuav tsum tau ceev cia ntawm 90 °, uas yog tau los ntawm cov tshuaj txhuam thiab cov khoom sib tsoo. Carbon txhuam thiab cov commutators tsim cov pa taws thiab toner thaum lub tshuab qig. Ntxiv nrog rau kev puas tsuaj rau lub cheebtsam, kev siv kuj tsawg. AC motors tsis muaj cov txhuam cov pa roj carbon monoxide thiab commutators. Lawv yog cov tsis pub dawb, rugged, thiab dav siv. Txawm li cas los xij, ua kom tau qhov sib npaug ntawm cov DC motors, cov cuab yeej siv tiv thaiv siv tau. Hnub no lub semiconductors tab tom loj hlob sai heev thiab lub hwj chim khoom hloov zaus yog sai npaum li cas, kev txhim kho kev kawm ntawm tsav tsav. Kev ceev ntawm cov microprocessor kuj ceev thiab ceev dua, thiab AC motor tswj tau muab tso rau hauv ob txoj kab rov tav ntawm ob sab sib npaug, thiab AC lub cev tam sim no hauv ob txoj kab yog qhov yuav tsum tau tswj kom tau zoo xws li DC motor control thiab yog sib npaug rau DC lub cev. kev ua tau zoo.
