Maitiro ekuyedza Stator ine Multimeter (3-Nzira Yekuyedza Gwaro)
Zviri mukati
Iyo alternator, inosanganisira stator uye rotor, inopa simba injini nekushandura simba remagetsi kuita magetsi uye inochaja bhatiri. Ndosaka, kana chimwe chinhu chisina kumira zvakanaka ne stator kana rotor, motokari yako ichava nezvinetso kunyange kana bhatiri yakanaka.
Kunyange zvazvo rotor yakavimbika, inonyanya kutadza kukundikana nokuti ine stator coils uye wiring. Naizvozvo, kutarisa stator ine yakanaka multimeter inhanho yakakosha mukugadzirisa matambudziko alternators.
Aya matanho anotevera achakubatsira iwe kuyedza stator nedhijitari multimeter.
Nzira yekutarisa stator ne multimeter?
Kana iwe uine dambudziko kubhadharisa mota yako kana mudhudhudhu, inguva yekuburitsa DMM yako.
Kutanga, isa iyo DMM kune ohms. Uyezve, paunobata waya dzemamita, skrini inofanirwa kuratidza 0 ohms. Mushure mekugadzirira iyo DMM, edza bhatiri nemamita anotungamira.
Kana iyo DMM ichiverenga yakatenderedza 12.6V, bhatiri rako rakanaka uye dambudziko rinonyanya kuve neiyo stator coil kana stator waya. (1)
Pane nzira nhatu dzekuyedza stators:
1. Stator static test
A static test inokurudzirwa kana uchinetseka kuchaja mota yako kana mudhudhudhu. Zvakare, iyi ndiyo chete bvunzo yaunogona kumhanya kana mota yako isingatangi. Iwe unogona kubvisa stator kubva kumotokari yemotokari kana kuiedza mujini yacho pachayo. Asi usati watarisa kukosha kwekupokana uye kutarisa ipfupi muwaya dze stator, ita shuwa kuti mota yakadzimwa. (2)
Mune static stator bvunzo, anotevera matanho anoitwa:
(a) Dzima injini
Kuti utarise mastators mune static mode, injini inofanira kudzimwa. Sezvambotaurwa, kana mota ikasatanga, iyo stator static bvunzo ndiyo chete nzira yekuyedza iyo stator.
(b) Gadzira iyo multimeter
Isa iyo multimeter kuDC. Isa iyo nhema inotungamira yemultimeter mune dema COM jack, zvinoreva kuti Common. Waya dzvuku ichapinda mune dzvuku slot ine zviratidzo "V" uye "Ω". Ita shuwa kuti waya tsvuku haina kubatirwa muAmpere connector. Inofanira kunge iri muVolts/Resistance slot.
Iye zvino, kuti uedze kuenderera mberi, shandura iyo DMM knob uye iise kune beep chiratidzo sezvo iwe unonzwa beep kuti uone kuti zvese zvakanaka nedunhu. Kana usati wamboshandisa multimeter kare, ndapota verenga bhuku rekushandisa usati waishandisa.
(c) Mhanya bvunzo yakamira
Kuti utarise kuenderera mberi, isa ese ari maviri multimeter probes mune stator sockets. Kana iwe ukanzwa beep, dunhu rakanaka.
Kana iwe uine matatu-phase stator, unofanirwa kuita bvunzo iyi katatu, uchiisa iyo multimeter probes muchikamu chekutanga uye chikamu 1, chikamu 2 uye chikamu 2, uyezve chikamu 3 uye chikamu 3. Kana iyo stator yakanaka, iwe inofanirwa kunzwa beep mune zvese zviitiko.
Nhanho inotevera ndeyekutarisa ipfupi mukati me stator. Bvisa waya imwe kubva pane stator socket uye bata stator coil, pasi kana mota chassis. Kana pasina chiratidzo chezwi, saka hapana pfupi pfupi mu stator.
Zvino, kuti utarise maitiro ekupikisa, isa iyo DMM knob kune iyo Ω chiratidzo. Isa iyo multimeter inotungamira mune stator sockets. Kuverenga kunofanira kuva pakati pe0.2 ohms uye 0.5 ohms. Kana kuverenga kuri kunze kweiyi chiyero kana kuti yakaenzana nekusingaperi, ichi chiratidzo chakajeka chekukundikana kwe stator.
Tinokupa zano kuti uverenge bhuku rebasa remotokari yako kuti uzive kuverenga kwakachengeteka.
2. Stator dynamic test
Iyo inosimba stator bvunzo inoitwa zvakananga pamotokari uye inotsigira iyo multimeter mu AC modhi. Izvi zvinoedza rotor, iyo ine magineti uye inotenderera yakatenderedza stator. Kuita bvunzo ine simba stator, matanho anotevera anoitwa:
(a) Dzima moto
Kutevera maitiro akafanana neyeye static bvunzo, isa iyo multimeter inotungamira mumasokisi e stator. Kana iyo stator iri yechitatu-phase, iyi bvunzo inofanira kuitwa katatu nekuisa probes muzvigadziko zvechikamu 1 uye chikamu 2, chikamu 2 uye chikamu 3, chikamu 3 uye chikamu 1. Nekudzima moto, haufanirwe kutora. chero kuverenga paunenge uchiita bvunzo iyi.
(b) Ignition ine ignition switch
Tanga injini uye dzokorora kupisa kwepamusoro kune imwe neimwe yezvikamu. Iyo multimeter inofanira kuratidza kuverenga kwe25V.
Kana kuverenga kwechero chikamu kwakadzikira zvakanyanya, taura kutenderera 4-5V, zvinoreva kuti pane dambudziko neimwe yezvikamu uye yave nguva yekutsiva stator.
(c) Wedzera kumhanya kweinjini
Dzokorora injini, wedzera rpm kusvika ku3000 uye dzokorora. Panguva ino multimeter inofanira kuratidza kukosha kwe60 V, uye ichawedzera pamwe chete nehuwandu hwekuchinja. Kana kuverenga kuri pasi pe60V, dambudziko riri ne rotor.
(d) Regulator rectifier bvunzo
Iyo regulator inochengeta iyo voltage inogadzirwa ne stator pazasi pemuganhu wakachengeteka. Batanidza stator yemota yako kune regulator uye isa iyo DMM kuti itarise maamps pachiyero chakaderera. Batidza moto uye zvese zvinobatidza uye bvisa iyo negative bhatiri tambo.
Batanidza iyo DMM inotungamira munhevedzano pakati peiyo yakaipa danda rebhatiri neiyo yakaipa danda. Kana bvunzo dzese dzakapfuura dzaive dzakanaka, asi iyo multimeter inoverenga isingasviki 4 amps panguva iyi bvunzo, regulator rectifier inokanganisa.
3. Kuongorora kunoonekwa
Static uye ine simba inzira mbiri dzekuyedza stators. Asi, kana iwe ukaona zviratidzo zvakajeka zvekukuvadza kune stator, somuenzaniso kana inoratidzika yakatsva, ichi chiratidzo chakajeka che stator yakaipa. Uye haudi multimeter yeizvi.
Usati waenda, unogona kutarisa mamwe Tutorials pazasi. Kusvikira chinyorwa chedu chinotevera!
