Indlela hlola multimeter motor: isinyathelo ngesinyathelo imiyalelo kanye nezincomo

Ngokuvamile nawu umbuzo, indlela ukuhlola motor ngemuva kokuhluleka, futhi ngemva ukulungisa, uma lungenayo ujike. Kunezindlela eziningana: luhlolo lwangaphandle, sokumelela ekhethekile, "embili" emazombezombe multimeter. Indlela yokugcina iyona ukonga kakhulu futhi enza izinto ezihlukahlukene, kodwa inikeza imiphumela efanele akuzona njalo. Iningi postoyannikov emazombezombe ukumelana cishe zero. Ngakho-ke, busebenze lutholakala ngokuba nesilinganiso.

motor design

Ukuze ufunde ngokushesha ukuthi uhlole motor, udinga ukuthi sicacise ukuthi imininingwane eyisisekelo kudivayisi. Liyisisekelo sako konke motors kuyinto ezimbili ingxenye isakhiwo: a Rotor kanye stator. Uphiko sokuqala njalo ijikelezwe ngaphansi kwethonya ensimini kagesi, i-umile yesibili futhi nje kudala ukugeleza vortex.

Ukuze uqonde ukuthi ukuhlola motor, udinga okungenani kanye ukwenza izandla zakhe siqu. abakhiqizi ezahlukene ezakhayo ezahlukene, kodwa uphethwe wengxenye kagesi isimiso kuze kube manje uhlala ingashintshiwe. Phakathi Rotor kanye stator igebe lapho kungaba buthelela swarf ngesikhathi izindlu unsealing.

Bearings ngesikhathi bafake angakhiqiza izinkomba ngokweqile zamanje, okuholela isivikelo esiyoba ungqongqoze. Ukuhlaziya umbuzo indlela isheke motor, ungakhohlwa mayelana mechanical ukulimala ezihambayo izingxenye futhi Borno lapho othintana nabo.

nobunzima zokuxilonga

Ngaphambi isheke motor multimeter, baphathe zangaphandle ukuhlolwa umzimba ukupholisa impeller, hlola izinga lokushisa kwe-izandla ngokuthinta evele metal. Leli bhokisi evuthayo imibukiso zamanje overvalued ngenxa yezinkinga ingxenye lokukhanda.

Hlaziya isimo sangaphakathi Borno, hlola yobunzima ka imishudo namantongomane. Uma okugwenyiwe izingxenye wamanje-lithwele inqwaba yezimpahla ukwehluleka Windings singenzeka nganoma yisiphi isikhathi. Engine ebusweni zigezwe ebhuqwini umswakama ngaphakathi lingekho.

Uma sicabanga umbuzo kanjani ukuqinisekisa motor multimeter, kubalulekile ukuba sicabangele ezinye umehluko wemisindo nemiqondo yamagama:

• imikhaza Ngaphezu kwalokho multimeter isidingo yokuxhumana yokulinganisa Ukudlula wamanje ngokusebenzisa ucingo.
• Multimeter kungaba ukukala ukumelana kuphela ethe xaxa. Ukuze uhlole isimo ukwahlukanisa (lapho ukumelana - kusukela ohms ukuba megohms) megoommetr esetshenziswa.
• Ukuze bafinyelele iziphetho mayelana yiqiniso kwalesi motor, unqamule izingxenye mechanical (gearbox futha, njll) noma kudingeka siqiniseke we ukuseviswa egcwele lezi zingxenye.

imishini Ishintshela

Ukuqala emazombezombe Ukujikeleza wasebenzisa ibhodi noma edluliselwe. Ukuze uqale ukubhekana umbuzo kanjani ukuhlola motor emazombezombe, kubalulekile ukuba bayazehlukanisa supply chain. Through kungenzeka "ukushaya" izakhi ukulawula ibhodi ukuthi uzokwenza iphutha nesilinganiso. Lapho eyama izintambo kungaba ukukala voltage engenayo qiniseka besifunda ezinhle electronic.

Ngo zasendlini izinjini njalo isicelo isakhiwo ekuqaleni emazombezombe, eyeqa ukumelana zokusebenza inductance. Uma izilinganiso acabangele yokuthi bangakwazi ukwethula wamanje ukubuthwa ibhulashi. Ngesikhathi iphuzu ukuxhumana Rotor livela ezifakwa njalo, asuse, udinga ukubuyisela ephephile kufanelekile emabhulashini phakathi ukujikeleza.

Umshini wokuwasha esetshenziswa motors wosayizi omncane nge run emazombezombe. Lonke okushiwo uphethwe kuyehla kube yizilinganiso ukumelana layo. Lamanje okungukuthi elinganisiwe kancane njalo, kodwa lift izici at ezahlukene ngesivinini kungenzeka draw iziphetho mayelana ukuseviswa we motor.

Yekuchumana uphethwe kagesi

Cabanga indlela ukuhlola ukuseviswa we motor. Ngokuyinhloko ngokuvakashela contact uxhumano. Uma abanayo umonakalo obonakalayo ke wavula indawo injini wiring ukuxhumana futhi ukhiphe kubo. Kungcono ukucacisa uhlobo motor. Uma kuyiyo ngalendoda, kukhona slats noma izigaba endaweni emabhulashini kufanelekile.

Ukuze kubonakale i ukumelana ohmmeter phakathi ngamunye slats eduze. Kufanele kube okufanayo kuzo zonke izimo. Uma kukhona ingxenye sesiwancamulile noma break yabo, motor kufanele tachosensor esikhundleni. Uma "prozvanivat" Rotor ikhoyili ngokwayo, bese kuba imitha 12 bangase babe owanele. Ukuze ukuhlola ngokunembile isimo emazombezombe, kudingeka kumthombo wamandla ongaphandle. Kungaba block kusukela PC noma ibhethri.

Ukulinganisa encane amagugu ukumelana in uchungechunge ne Resistor elinganisiwe emazombezombe efakwe zenani eliyimali ezaziwayo. Ubufakazi obanelisayo ukukhetha ukumelana ohms-20. Ngemva amandla supply emandleni zangaphandle ulinganise iconsi voltage yonkana emazombezombe futhi Resistor. Inani okuholela eyatholakala kusukela ifomula-R1 = U1 *-R2 / U2, lapho u-R2 - Resistor, U2 - yokwehla kwamandla yonkana ke.

Ukuxilongwa motors indlela

On the umshini zezimboni egeza ungasebenzisa enamandla ezintathu okhombisa izinjini. Rotor kaningi kwenziwe ngesimo amapuleti ubhala nengaphakathi kazibuthe. Isigaba Windings ngokuvamile fixed kanye wahlela stator. Multimeter ukuhlola injini enjalo ilula kakhulu. Ohmmeter kudingeka ikhale ukumelana ngamunye emazombezombe. Kufanele kube okufanayo. Ungakhohlwa ukuhlola isampula emzimbeni by sokulinganisa ukumelana izindlu. Nokho, ukwahlukanisa isheke Megger.

Iphendula umbuzo kanjani ukuhlola motor emazombezombe umhloli, kufanele kuphawulwe ukuthi "isigaba ukungalingani" e motor indlela akuvumelekile. Ukumelana umehluko kumele singeqi eyodwa Ohm. Kungenjalo, inyuka wamanje ngesikhathi inductance encishisiwe, okuholela ukuhanguka emazombezombe.

Uma DC motor

izinjini okunjalo emazombezombe ukumelana sincane kakhulu kanye izilinganiso kwenziwa esebenzisa amadivayisi amabili. Kanyekanye ukuthatha ukufundwa nge ammeter futhi voltmeter. Njengoba umthombo akhethiwe ibhethri voltage ka 4-6 V Inani nomphumela ebizwa ngokuthi ifomula R = U / I.

Hlola zonke Windings we ukumelana armature, ukukala ukubaluleka phakathi amapuleti ngalendoda. Wonke la manani kufanele ilingane imitha. Ngokuqhathanisa singaqondile, singafinyelela eziphethweni njengoba ukuhlola armature motor.

Umehluko ukumelana phakathi amapuleti eduze izinkomba ngalendoda bavunyelwe akukho ngaphezu kuka 10%. Lapho ifomu factor inikezwe Yikhoyili nokulingana, ukusebenza motor kuyoba evamile lapho umehluko uyakwazisa 30%. Multimeter ukufundwa abaziniki njalo Ukubikezela olunembile mayelana nesimo se-motor umshini wokuwasha. Ngaphezu kwalokho, injini ngokuvamile kudinga ukuhlaziya umsebenzi yokumba Samandla.

Ihlola oqondile drive imoto

Uma sicabanga umbuzo kanjani ukuhlola motor umshini wokuwasha, kubalulekile ukuba acabangele uhlobo uxhumano kushaft sigubhu. It kuncike lolu hlobo Umklamo kagesi ingxenye. Multimeter prozvanivatsya emazombezombe futhi bafinyelela iziphetho ubuqotho babo.

isheke Impilo Kwenziwa ngemva kokwakhiwa kweHholo inzwa esikhundleni. Nguye owehlele ezimweni eziningi. Ngemva phambili Windings lapho ubuqotho amakhosi abanolwazi ukuncoma ukuxhuma motor ngqo inethiwekhi 220 V Umphumela umjikelezo iyunifomu ukushintsha isiqondiso sayo, ungakwazi perevotknut ipulaki ku esitolo esidayisa, ukuyivala omunye oxhumana nabo.

Le nqubo elula kusiza ukuhlonza inkinga evamile. Nokho, ukuba khona Ukujikeleza akuqinisekisi operation evamile kuyo yonke ngaphandle ngesikhathi umjikelezo spin futhi hashaza izindlela.

Kulandzelana kwalokucuketfwe lokuhleliwe uphethwe

Into yokuqala sincoma ngokushesha sinake isimo emabhulashini, izintambo. Nagar ku izingxenye bukhoma ebonisa izimo ongaphilile yenjini. Ngokwabo abaqoqi kufanele ibe bushelelezi, ngaphandle ngokuhlaziya futhi igawula. Imidwebo futhi abangele arcing, okuyinto elimaza motor Windings.

Ngo imishini yokuwasha Rotor is angahluleli ngendlela eqondile, ngoba kwenzeka aqhephukile noma slats eziphukile. Ibhodi yokulawula yengamela isikhundla Rotor nge Hall inzwa noma tachogenerator, ungeza noma ukunciphisa voltage osetshenziswayo lekhoyili ukusebenza. Kusuka lapha kukhona komsindo lapho ujikelezisa, isusa okuthile okungavamile ngesikhathi umjikelezo spin.

Lesi simo esiyingqayizivele sibangelwa kungabonwa ngesikhathi umjikelezo spin kuphela imodi wokugeza Kunenkolelo stably. Ukuxilonga imishini akusho ngaso sonke isikhathi zidlule ukuhlaziywa kagesi ingxenye. I Mechanics kungaba imbangela ukungasebenzi. Ngaphandle kulayishwa injini ungakwazi spin ngempela ngokulinganayo futhi kancane kancane kuragela.

Uma Nokho, sidilize Ukuvikelwa?

Ngemva izilinganiso owazenza iphutha elintantayo is hhayi Kunconywa ukuba ukuxhuma kunethiwekhi ukuqinisekisa. Ungabonisa injini phansi ngokuphelele, engazi inkinga. Indlela hlola imoto emazombezombe multimeter, ukutshela inkosi sesevisi ngocingo. Ngaphansi kwesandla sakhe, kuyoba lula ukucacisa uhlobo olunjani lwesakhiwo futhi oda zokuxilonga okuyiphutha umshini wokuwasha.

Nokho, ngokuvamile abantu futhi izingcweti abanolwazi akakwazi ukubhekana eyinkimbinkimbi ukulungisa lapho iphutha ezintantayo. Ukuze uhlole uma ufuna ukusebenzisa umshini wokuwasha, abagxeka izingxenye lokukhanda. Misalignment shaft motor icala ekhethekile zezinkinga ukujikeleza sigubhu.
