Ua ntej, BISHENG WD-E offset xovxwm
Ceeb Toom: Pib lub tshuab thiab pom tias tus menyuam uas muaj tus lej I-ink tsis tig.
Kev soj ntsuam thiab kho dua tshiab: Qhib lub qhov rooj ntawm lub tshuab (plaub zaug ntawm dej thiab number case speed control devices), thiab nrhiav tau tias lub teeb liab ntawm ib qho ntawm cov ceev regulating Circuit Court boards yog kaj (qhia tias txhaum), thiab kov lub kawg ntawm lub rotor ncej thaum nyob rau thaum xaus ntawm lub cev los ntawm txhais tes. - Yeej tsis tig. Xav tias lub tshuab yog ib lub tshuab tshiab khiv thiab tsis muaj kev tswj hwm kev tswj hwm kev tswj hwm, nws tsuas yog tau hloov lub cav kuaj seb puas txhaum. Txav thiab ntxig lub cav rau hauv lub hwj huam kab ntawm tus II cwj pwm tsav. Kev xeem tshuab: II number case motor khiav feem ntau, thiab thawj lub teeb liab kev tswj lub rooj tsav xwm lub rooj tsavxwm tau xa rov qab rau lub teeb ci ntsuab (zoo hauv lub xeev); tab sis kuv tus lej qia tseem tsis tig, thiab qhov sib npaug ntawm cov tswj hwm kev teeb tsa ntawm lub rooj teeb liab teeb liab liab, qhia tias qhov ua txhaum yog los ntawm kev puas tsuaj ntawm qhov I-Motor lub cev (tab sis qhov tseeb cov ntaub ntawv ntawm ob lub tshuab tsis pom. ) Thaum lub hwj chim muab tua lawm, kuv tus cwj mem kua luam tawm raug tshem tawm nrog qhov txo reducer, thiab mam li hloov nrog tus tshiab number case kua nplaum, thiab tom qab ntawd ces tus ntsaws nws tus kheej rov qab los. Lub cav fais fab tuag: Kuv tus lej cim thiab II cwj pwm tsav yog cov khiav txhua zaus. Vim li cas thiaj yuav tsum tau ua txhaum tawm ua ke nrog qhov txo reducer? Lub ntsiab yog vim tias lub cav raug hloov los ntawm ib lub cav xwb, yog tias lub cav thiab qhov ceev tsis tuaj yeem tsis tuaj yeem ua ke, nws yooj yim ua rau lub tshuab tsis muaj kev ploj los yog tsis meej pem thaum lub sijhawm ua haujlwm, thiab lub sijhawm yog ntev thiab lub engine yog yooj yim puas.
Qhov ob, JS2102 offset xovxwm
Cim 1: Hauv kev luam ntawv, lub tsho ntev dheev tsis suav.
Kev soj ntsuam thiab kev kho dua: Tom qab paub tias, lub transistor xa cov teeb liab suav mus rau lub txee nyob ze rau qhov tso zis ntawm qhov pib hloov (feem ntau, cov thooj hlau uas yog synchronous nrog lub tshuab yuav tsum kis tau (thaiv)) (transistor interruption switch), thiab cov transistor nyob ze rau qhov pib. Thaum nws qhib rau, lub tshuab hlau muab tua thiab muab tua - qhov teeb liab mem tes raug xa mus thiab lub txee tuaj yeem suav. Hwj chim tawm, Tom qab lub transistor raug tshem tawm ntawm kev sib thooj, nws tau ntsuam xyuas: tsis muaj qhib qhov hluav taws xob ntawm lub oscillating coil los yog cov pob txha cov pob qij txha ntawm qee lub cheebtsam. Lwm cov hwj huam mov yog rov kuaj dua: qhov tso zis los ntawm cov hlau phaj, thiab cov zis tshuav tawm tau qhov tso zis tawm; thiab siv ntau qhov hluav taws xob DC voltage cov ntaub ntawv siv los ntsuas qhov ntsuas hluav taws xob tau xa los ntawm cov kab hauv pem hauv ntej ntawm tus tswj electrode thiab cov cathode ntawm thyristor. Yuav tsum tsis txhob nres. Nws yog ces xav tias muaj cov leak ntawm lub anode thiab cathode ntawm tus thyristor. Thaum lub hwj chim muab tua, cov thyristor tau siv cov hluav taws xob tshuab fais fab, thiab siv ntau qhov kev sib thooj los siv los xyuas tias tsis muaj kev tawm ntawm lub anode thiab cathode. Tab sis kuv xav hais tias txij thaum cov pa tawm muaj, nws yuav tsum yog tias lub ntsiab lus tseem ceeb tseem muaj teeb meem! Rectifier fais fab mov Circuit Court tau kuaj dua ntxiv nrog rau cov ntaub ntawv siv ntau hom kabmob, thiab ib qho ntawm cov duab rectifier tau pom muaj tawg lawm. Tom qab hloov mus rau ib qho diode tshiab ntawm tib hom, sim dua thiab teebmeem.
Cim 2: Thaum lub sij hawm luam ntawv, lub tshuab dheev poob los ntawm kev kub ceev mus qis qis thiab txawm nres.
Kev soj ntsuam thiab kev kho dua: Tom qab kev soj ntsuam, nws tau pom tias tom qab lub kaw lawm, tus neeg tsav lub zog ntawm lub tshuab hluav taws xob uas siv hluav taws xob, tus tsav AC, nws tseem ua haujlwm zoo, tab sis tus nplais khawm tsis hloov. Piav tias qhov teeb meem yog nyob rau hauv qhov txauv khawm. Txawm li cas los xij, thaum lub teeb pom kev nyob ntawm lub vaj huam sib luag ntawm lub npov ntawm lub teeb, nws qhia tau hais tias DC lub ntsiab hluav taws xob zoo, thiab qhov txhaum yog nyob rau hauv qhov kev tswj fais fab. Fais tawm, lub npov tswj kev tshem tawm, thiab cov cwj pwm ntawm cov transistors tseem kuaj tau los ntawm cov kab lus ua haujlwm ntau dhau los: nws pom tau tias peb lub electrodes ntawm BG3 (triode) thiab BG4 (ib qho kev sib txuas ntawm transistor) tsis txuas nrog txhua tus , qhia txog tias ob lub raj muaj lub hau kheej tau tshuab (ntawm chav kawm, tsis muaj mem tes yuav raug xa mus ua kom thyristor lub lag luam ntawm lub ntsiab Circuit Court). Hloov tag nrho ob lub raj, sim lub tshuab: lub tshuab tseem tsis tig. Siv lub tshuab thev naus laus taw (DC voltage) los xyuas txog BG3 thiab BG4 tee kev khiav hauj lwm muaj qhov tseem ceeb tsawg heev, qhov sib npaug ntawm qhov 3 thiab 1 ceg ntawm qhov kev thaiv NE555 kuj tsis tshua muaj; rov ntsuas lawv lub hwj huam: R2 (ua hauj) ntawm qhov dav hlau voltage yog 15V, cov zis voltage 14V, obviously nws yog deb ntawm tus 24V voltage tus nqi uas yuav muab los ntawm qhov fais fab transformer secondary (boosted ntawm diode ib nrab yoj rectification thiab cov roj capacitor)! Fais fab, tawm cov khoom siv hluav taws xob tswj lub rooj sib txuas, thiab siv ob sab lim dej sib txuas nrog lub hwjchim los mus ntsuas nrog lub multimeter ua ntaub ntawv (thaum lawv tsis tuaj yeem, qhov tso zis hluav taws xob poob qis): Tus nqi them thiab kev ua haujlwm tawm yog qhov qub, tsis muaj teeb meem dab tsi. Fais fab tuag: Siv lub tshuab hluav taws xob ntau ntawm cov ntsuas hluav taws xob los ntsuas qhov teeb meem theem nrab ntawm lub tshuab hluav taws xob hauv lub rooj sib fais loj rau 24V, li qub. Qhov no qhia tau meej meej tias qhov txhaum yog tshwm sim los ntawm ib los yog ob qho tib si ntawm lub hwj huam mov regulators (V15 thiab V16). Txawm li cas los xij, txoj cai tswjhwm ntawm lub rooj sibtham tsis muaj cov kev tswjfwm ob qhov no (daim ntawv schematic tsis phim daim ntawv qhia tseeb). Yog li ntawd, nws tsuas yog siv thiab tshawb nrhiav: nws pom tau hais tias lub 7815 peb-qhov kev tiv thaiv kev tswj yog siv los hloov ob lub qhov hluav taws xob. Tom qab hloov ib qho tshiab 7815 peb qhov chaw tswj hwm thiab khi rau pawg tswj hwm rov qab rau hauv qhov chaw, sim dua thiab teeb meem.
