Kev Taw Qhia luv luv rau Radially Oriented NdFeB Ntiv Nplhaib Magnets
Ntau tus neeg siv hlau nplaum tau nyiam ua kom tsis meej pem radially magnetization nrog diametrical magnetization. Raws li lub npe implies, lub magnetization kev taw qhia ntawm radially magnetized nplhaib hlau nplaum yog raws lub radial vector. Rau sintered NdFeB hlau nplaum, radially magnetization yog raws li radially orientation, tab sis radially oriented NdFeB nplhaib hlau nplaum yog ua hauj lwm ntau raws li lub hauv paus kom tau txais multipole NdFeB nplhaib hlau nplaum.
Dhau li cov txheej txheem hmoov hlau metallurgy, radially oriented NdFeB nplhaib hlau nplaum tuaj yeem tsim los ntawm cov txheej txheem kub-deformed. Hmoov metallurgy txheej txheem tsis yooj yim rau kev tsim cov hlau nplaum nrog lub taub me me lossis qhov siab siab vim yog anisotropy ntawm cov tub ntxhais hluas lub modulus. Nyob rau hauv lub caij no, nws kuj yog ib qho nyuaj kom tau txais high orientation degree thiab sib nqus kev ua tau zoo vim qhov nyuaj orientation teb tsim. Cov txheej txheem kub-deformed siv nanocrystalline NdFeB hmoov raws li cov khoom siv raw thiab ntxiv nws mus rau hauv ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom, tom qab ntawd nws thiaj li tau txais tag nrho cov nplhaib hlau nplaum los ntawm cov txheej txheem kub deformation.
Hmoov Metallurgy txheej txheem
Magnetic field orientation thaum lub sij hawm molding txheej txheem siv kev sib cuam tshuam ntawm NdFeB hmoov thiab sab nraud magnetic teb los txiav txim qhov yooj yim magnetization kev taw qhia ntawm hmoov thiab ua kom nws raws li qhov kawg magnetization kev taw qhia. Lub hom phiaj tseem ceeb ntawm radially orientation teb suav nrog kev siv thev naus laus zis tsis tu ncua thiab suav nrog kev hloov pauv kev taw qhia thev naus laus zis.
Repulsive Orientation Technology
Sib nqus Circuit Court ntawm repulse orientation technology yog tsim los ntawm hluav taws xob coils thiab pwm. Tshwj xeeb tshaj yog, pwm mandrel thiab mounting lub tes tsho ntawm poj niam pwm txais cov khoom siv hlau nplaum. Punch thiab poj niam pwm yog ua los ntawm cov khoom siv tsis muaj hlau nplaum. Hluav taws xob coils muab tso rau ntawm qhov kawg ntawm pwm mandrel. Cov kev taw qhia tam sim no ntawm ob lub coils yog qhov sib txawv thiab yog li kev sib nqus magnetic teb yuav tsim cov radially magnetic teb rau orient hmoov. Repulsive orientation thev naus laus zis muaj qhov zoo tshaj plaws axial symmetry thiab yog li sib nqus kev ua tau zoo sib xws raws qhov ncig tuaj yeem lav. Txawm li cas los xij, magnetic force kab ntawm qhov siab qhov taw qhia yuav txawv ntawm lub dav hlau kab rov tav thiab tom qab ntawd txwv cov hlau nplaum qhov siab.
Rotating Orientation Technology
Rotating orientation technology siv hluav taws xob coil, kiv cua zoo li tus yoke hlau, thiab pwm mandrel los tsim cov kiv cua zoo li cov hlau nplaum, ces hmoov ntawm cov ces kaum sib txawv yog taw qhia nyob rau hauv succession vim yog kev sib hloov ntawm cov poj niam pwm. Rotating orientation thev naus laus zis tuaj yeem txo qhov kev taw qhia thaj chaw zoo thiab txhim kho lub zog sib nqus. Txawm li cas los xij, kev sib txuam ntawm qhov tseeb ntawm kev sib hloov mechanism yuav cuam tshuam rau concentricity ntawm lub nplhaib hlau nplaum thiab sib nqus kev ua tau zoo ib yam ntawm qhov ncig.
Kub-deformed txheej txheem
Nd2Fe14B theem tseem ceeb muaj cov qauv tetragonal thiab elastic modulus ntawm qhov yooj yim magnetization axis yog qhov tsawg. Rau isotropic nanocrystalline NdFeB hlau nplaum, nws yooj yim magnetization kev taw qhia yuav tsim kev nyiam kev taw qhia raws li kev taw qhia thaum kub deformation txheej txheem. Qhov tseem ceeb tshaj plaws ntawm cov txheej txheem kub-deformed yog tias nws tsis xav tau qhov chaw sib nqus rau cov hmoov nplej. Cov txheej txheem kub-deformed yog zoo haum rau siab L / D piv thiab nyias-phab ntsa nplhaib hlau nplaum.
