U Shaped vs Horseshoe Magnets: Qhov txawv & Yuav Ua Li Cas Xaiv

Koj puas tau tshawb xyuas cov hlau nplaum thiab tuaj hla ob qho "U-shaped" thiab "horseshoe" tsim? Thaum xub thawj siab ib muag, lawv zoo nkaus li zoo tib yam - ob qho tib si muaj lub iconic curved-rod saib. Tab sis ua tib zoo saib thiab koj yuav pom qhov sib txawv me me uas tuaj yeem cuam tshuam rau lawv qhov kev ua tau zoo thiab kev siv zoo. Kev xaiv cov hlau nplaum zoo tsis yog hais txog kev zoo nkauj xwb, nws yog hais txog kev siv lub zog sib nqus kom zoo.

Cia peb rhuav tshem cov hlau nplaum no "cov kwv tij loj":

1. Puab: Curves yog huab tais

Horseshoe hlau nplaum:Xav txog cov classic horseshoe zoo siv rau horseshoes. Cov hlau nplaum no muaj qhov sib txawvdav khoov, nrog ob sab ntawm khoov flaring me ntsis sab nraud. Lub kaum sab xis ntawm tus ncej yog obtuse ntau dua, tsim kom muaj qhov loj dua, nkag tau yooj yim ntawm cov ncej.

U-shaped hlau nplaum:Xav txog qhov tob, nruj dua "U", zoo li tsab ntawv nws tus kheej. Cov hlau nplaum no muaj ibntxaum khoov, tighter khoov, thiab ob sab yog feem ntau nyob ze ua ke thiab ntau parallel. Lub kaum sab xis yog sharper, nqa cov ncej los ze zog ua ke.

Visual Tip:Xav txog tus nees nees li "dav thiab flatter" thiab U-zoo li "qhov tob thiab nqaim."

 

2. Sib Nqus Field: Concentration vs. Accessibility

Cov duab ncaj qha cuam tshuam rau kev faib tawm ntawm cov magnetic teb:

Horseshoe Magnet:Qhov loj dua qhov sib txawv, qhov dav ntawm qhov sib nqus ntawm cov ncej thiab qhov tsis tshua muaj siab. Thaum lub magnetic teb tseem muaj zog nyob ze ntawm tus ncej, lub zog teb decays sai ntawm tus ncej.Qhov qhib tsim ua rau nws yooj yim dua rau tso cov khoom hauv thaj chaw sib nqus.

U-shaped hlau nplaum:Qhov khoov me me, qhov ze rau sab qaum teb thiab sab qab teb ncej. Qhov no ua rau lub zog teb ntawm cov ncej muaj zog thiab muaj zog ntau dua.Lub zog teb nyob rau hauv qhov sib txawv nqaim no ntau dua li qhov sib txawv ntawm qhov sib txawv ntawm cov hlau nplaum zoo sib xws.Txawm li cas los xij, qhov khoov loj dua qee zaum ua rau nws yooj yim dua los tso ib qho khoom ncaj nraim ntawm tus ncej piv rau qhov qhib horseshoe.

 

3. Kev siv tseem ceeb: Txhua tus muaj nws tus kheej lub zog

Qhov zoo tshaj plaws siv rau Horseshoe Magnets:

Kev Kawm Txuj Ci:Nws cov qauv zoo nkauj thiab qhib tsim ua rau nws zoo meej rau kev siv hauv chav kawm - yooj yim ua qauv sib nqus nrog cov ntaub ntawv hlau, khaws ntau yam khoom ib zaug, lossis ua qauv qhia txog kev nyiam / kev tawm tsam.

Lub hom phiaj dav dav nqa / tuav:Thaum koj xav tau los khaws lossis tuav cov khoom ferromagnetic (xws li, ntsia hlau, ntsia hlau, cov cuab yeej me) thiab cov ntsiab lus meej ntawm cov hlau nplaum tsis yog qhov tseem ceeb, qhov qhib tsim muab qhov yooj yim dua rau kev tso cov khoom.

Poles yuav tsum nkag mus tau:Tej yaam num uas yuav tsum tau yooj yim nkag tau los yog kev sib cuam tshuam nrog cov khoom nyob ze ntawm tus ncej (tsis yog ntawm lawv).

 

Qhov zoo ntawm U-shaped hlau nplaum:

 

Muaj zog tsom magnetic teb:Cov ntawv thov uas xav tau qhov siab tshaj plaws magnetic teb lub zog ntawm ib qho chaw nqaim tshwj xeeb. Piv txwv li, sib nqus chucks rau tuav hlau workpieces thaum lub sij hawm machining, tshwj xeeb sensor daim ntaub ntawv, los yog thwmsim uas yuav tsum tau ib tug muaj zog localized magnetic teb.

Kev siv electromagnetic:Feem ntau siv los ua cov ntsiab lus tseem ceeb ntawm qee hom electromagnets los yog relays, qhov uas tsom rau cov hlau nplaum yog qhov zoo.

Motors thiab generators:Hauv qee qhov DC lub cev muaj zog / lub tshuab hluav taws xob tsim, qhov sib sib zog nqus U-puab muaj txiaj ntsig zoo rau thaj chaw sib nqus nyob ib puag ncig ntawm armature.

 

 

U-Shaped vs. Horseshoe Magnet: Kev sib piv ceev

 

Thaum ob qho tib si horseshoe thiab U-zoo li tus hlau nplaum muaj cov qauv nkhaus, lawv cov duab lawv tus kheej txawv:

Curvature thiab Ncej Pitch: Horseshoe hlau nplaum muaj qhov dav, flatter, qhib curvature, nrog tus ncej taw feem ntau flaring tawm sab nraud, tsim kom muaj qhov chaw loj dua, nkag tau yooj yim ntawm cov ncej. U-shaped hlau nplaum muaj qhov sib sib zog nqus, nruj dua, nqaim curvature, nqa cov ncej kom ze zog ua ke hauv kev sib piv ntau dua.

Sib Nqus Field Concentration: Cov duab sib txawv no muaj kev cuam tshuam ncaj qha rau ntawm qhov chaw sib nqus. Cov hlau nplaum horseshoe muaj qhov sib txawv loj dua, ua rau muaj qhov dav dua tab sis tsis tshua muaj zog sib nqus ntawm nws cov ncej. Nyob rau hauv sib piv, U-shaped hlau nplaum muaj ib tug tsawg nkhaus curvature, uas ua rau ib tug ntau khaus thiab khaus magnetic teb nyob rau hauv lub nqaim qhov sib txawv ntawm nws ncej.

Accessibility vs. Concentration: Qhov qhib tsim ntawm horseshoe hlau nplaum ua rau nws yooj yim dua rau tso cov khoom hauv thaj chaw sib nqus los yog cuam tshuam nrog tus ncej. Qhov sib sib zog nqus U-puab tuaj yeem ua rau nws nyuaj me ntsis los nrhiav cov khoom nruab nrab ntawm nws cov ncej, tab sis qhov no yog sib npaug los ntawm nws qhov zoo dua cov hlau nplaum sib nqus hauv cov cheeb tsam tshwj xeeb.

Cov txiaj ntsig zoo: Cov hlau nplaum Horseshoe muaj ntau yam thiab zoo tagnrho rau kev kawm, kev ua qauv qhia thiab lub hom phiaj dav dav, nrog kev yooj yim ntawm kev tuav thiab thaj chaw dav dav. U-shaped hlau nplaum yog tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov ntawv thov uas yuav tsum tau tuav lub zog siab tshaj plaws hauv qhov chaw kaw, muaj zog hauv zos sib nqus (xws li cov hlau nplaum sib nqus) lossis cov qauv siv hluav taws xob tshwj xeeb (xws li motors, relays).

 

Yuav Xaiv Li Cas: Xaiv Koj Cov Hlau nplaum zoo meej

Kev xaiv ntawm U-shaped thiab horseshoe hlau nplaum nyob ntawm koj cov kev xav tau tshwj xeeb:

Lub luag haujlwm tseem ceeb yog dab tsi?

Xav tau lub zog siab tshaj plaws hauv qhov chaw me me (piv txwv li kom tuav nyias nyias workpieces)? 

Mus nrog U-shaped hlau nplaum.

Yuav tsum ua kom pom cov hlau nplaum, khaws cov khoom xoob, lossis yooj yim nkag mus rau cov ncej?

Mus nrog ib tug horseshoe hlau nplaum.

Yuav tsum tau txuas cov hlau nplaum rau ib yam khoom loj?

Need tuav cov khoom ze heev rau ib leeg?                                                                     

Cov hlau nplaum ntawm U-zoo li cov hlau nplaum yog ntau concentrated.

Cov khoom tawg tawg lossis xav tau thaj chaw tuav loj dua? 

Cov hlau nplaum horseshoe muaj thaj tsam dav dua.

 

Cov ntaub ntawv tseem ceeb, ib yam nkaus!

 

Ob daim duab hlau nplaum tuaj hauv cov khoom sib txawv (Alnico, Ceramic / Ferrite, NdFeB). NdFeB hlau nplaum muaj lub zog tuav lub zog ntawm ob daim duab, tab sis nkig ntau dua. Alnico tuaj yeem tiv taus qhov kub thiab txias. Cov hlau nplaum ceramic yog tus nqi-zoo thiab feem ntau siv rau hauv kev kawm / lub teeb-lub luag haujlwm horseshoes. Ntxiv rau qhov zoo, xav txog cov khoom siv zog thiab kev xav tau ib puag ncig.

Xav txog practicality:

Yog tias qhov yooj yim ntawm kev tuav thiab tso ntawm cov khoom yog qhov tseem ceeb, qhov qhib tsim ntawm tus nees nees feem ntau yeej.

Yog tias tuav lub zog hauv qhov chaw kaw yog qhov tseem ceeb, U-shaped hlau nplaum yog qhov zoo tagnrho.
