Kev taw qhia thiab qhov zoo ntawm cov tshuab hluav taws xob rectifier
Lub tshuab hluav taws xob tshuab hluav taws xob yog lub tshuab tsis txhuam hauv lub tshuab uas tswj los ntawm lwm cov khoom hluav taws xob. Cov khoom siv hluav taws xob kuj yog ib qho hluav taws xob hauv hluav taws xob los yog ib tus neeg tsav tsheb sib txawv. Qhov kev coj ua ntawm kev sib txeeb txhua yam yog nyob ntawm qhov hluav taws xob circuitry. Lub rooj tsavxwm tuaj yeem hloov qhov theem ntawm qhov kev sib tw tseg thiab xyuas kom lub tshuab tig rov qab los muab ib qho chaw uas tsim nyog tam sim no. Yuav tsum ua tiav siab yog tias tam sim no yog xa hauv qhov tseeb los ntawm ib qho sijhawm ntawm lub sijhawm. Txij thaum khiav ceev ntawm lub electrodes yog tswj los ntawm lwm cov khoom siv hluav taws xob, lub tshuab hluav taws xob ua lub tshuab hluav taws xob tsis muaj ib qho kev txwv tsawg.
Lub tshuab hluav taws xob rectifying muaj qhov zoo li nram qab no: Vim tias hom cav no tsis txhuam, nws yuav tsis tsim Mars los yog lub cav yuav luv zog vim txhuam, thiab yuav tsis khib zog, vim nws siv hluav taws xob cov cuab yeej los tswj tus stator, nws qhov kev ua tau zoo thiab kev sib ntxub Zoo sib deev. Piv rau induction motors, lawv cov kev khiav hauj lwm muaj qis dua. Lub me me loj me me, qhov chaw ntau qhov chaw dim, thiab qhov chaw ntxiv txawm yog rua thaum lub chaw tsim khoom siv ib qho rotor sab nraud.
Yog siv hluav taws xob tshuab hluav taws xob (electronically commutated engine), lub tshuab hluav taws xob kuj tseem huv. Lub cav tsis txhuam ntswj yog tsav los ntawm DC lub hwj chim tshwj xeeb, thiab AC lub zog qhov hluav taws xob ua kom muaj nqi ntxiv thiab tsim teeb meem ntau dua. Lub tshuab hluav taws xob ntawm lub tshuab hluav taws xob tau ncaj qha mus txuas rau AC mains, tiam sis nws tsis yog nyob ntawm qhov muaj hluav taws xob los yog muaj zog tsawg, thiab kev hloov me me tsis hloov rau lub cav tawm.
Yog hais tias lub tshuab hluav taws xob sib txuas ntawm lub tshuab hluav taws xob yog muab piv nrog AC AC lub cev uas muaj lub cev los yog ib qho kev sib tsoo ntawm AC lub zog (ACpermanent-splitcapacorormotor), nws yuav pom tau tias qhov ntau ntawm qhov kev sib tsoo lub cev muaj zog yog 15% -25%, taag theem sib cais. Cov Capacitor-type alternating current motors (PCS) yog li ntawm 30% mus rau 50%, thaum siv hluav taws xob tshuab hluav taws xob muaj txij li 60% txog 75%.
Electronically commutated motors tuaj yeem siv rau hauv cov ntawv siv nrog cov qis zog, xws li cov kiv cua me me, servo motors, thiab kev tswj xyuas lub zog. Cov cai tshiab tam sim no raug sim ua kom siv daim ntawv tsav tsheb no mus rau cov khoom siv hluav taws xob xws li cov twj thiab cov khoom siv sib txuas.
Nyob rau hauv cov nqe lus ntawm kev tswj ceev, lub tshuab electronically commutated motor muaj multi-ceev tswj kev ua haujlwm, thiab lub voj kev ceev yog nws cov accessory txheem. AC motors kuj muaj kev tswj hwm feem ntau thiab muab kev xaiv kom tswj tau nrawm. Tus sab nraud lwm tus tuaj yeem hloov kho qhov hluav taws xob (transforming voltage (incomingvoltage), uas muaj peev xwm pauv tau sine yoj, uas yuav cuam tshuam rau lub neej ntawm kev tsav tsheb thiab nce lub suab nrov.
Kev siv tshuab hluav taws xob sib txuas rau electronically, qhov tshuab xaws hluav taws xob dav ntawm qhov rectifier Circuit Court yog 4-20 mA, qhov hluav taws xob yog 0-10 V, thiab qhov tsav ceev yog tswj li ntawm 10% -100%. Lub tshuab hluav taws xob rectifier yuav raug saib xyuas los ntawm kev siv ib qho kev sib xyuas, thiab tus tsim qauv yuav muab tau cov lus qhia tawm tswv yim. Electronically commutated motors kuj muaj cov softstart nrog cov suab nrov tsawg thiab lub cev muaj zog.
