Multipole nplhaib hlau nplaum yog ib qho kev xav tau ntau dua rau cov hlau nplaum ruaj khov thiab cov khoom sib nqus sib nqus hauv kev sib piv nrog cov pa sib txuas ntau cov hlau nplaum. Nws tuaj yeem raug cais rau hom isotropic thiab anisotropic hom. Hom isotropic feem ntau yog hais txog lub nplhaib-zoo li cov hlau nplaum sib txuas nrog ntau tus ncej. Anisotropic hom, los yog multipole sintered nplhaib hlau nplaum, yeej ib txwm tau touted raws li ib tug high-end khoom.
Hais txog Multipole Sintered Nplhaib Magnet
Siv sintered Neodymium hlau nplaum ua piv txwv, xws li radial orientation lossis multipole orientation tuaj yeem ua haujlwm los tsim ntau lub nplhaib sintered hlau nplaum. Radially oriented nplhaib hlau nplaum ua los ntawm radial orientation tuaj yeem ncaj qha magnetized rau multipole raws radial vector. Lub hom phiaj tseem ceeb ntawm radial orientation magnetic teb muaj xws li tsoos repulse orientation technology thiab Suav cim rotating orientation technology.
Multipole sintered nplhaib hlau nplaum tsim los ntawm multipole orientation tseem hu ua polar anisotropic hlau nplaum. Orientation magnetic teb ntawm polar anisotropic hlau nplaum yog tsim los ntawm pulser coil. Nws cov kab flux nkag mus rau S polars uas nyob ib sab los ntawm N polars thiab nthuav tawm qhov nkhaus faib, yog li cov hmoov sib nqus kuj tam sim no nkhaus. Sib nqus teb lub zog waveform ntawm polar anisotropic hlau nplaum yog ze rau sinusoidal thiab zoo heev rau daim ntawv thov lub cev muaj zog.
Dhau li ntawm sintering thev naus laus zis, cov txheej txheem kub-deformation yog lwm qhov kev daws teeb meem kom tau txais ntau lub nplhaib Neodymium nplhaib hlau nplaum thiab.
Waveform vs. Motor Performance
Kev ntsuas kev sib piv ntawm ntau lub nplhaib hlau nplaum yog qhov tshwj xeeb ntawm kev sib nqus lub zog waveform, nws cov tsis zoo li tus nqi ncov, lub kaum sab xis, thiab lub voj voog lub luag haujlwm yog ze rau kev ua haujlwm ntawm lub cev muaj zog. Peak qhov tseem ceeb tuaj yeem qhia tau qib ntawm cov hlau nplaum thiab qib saturation ntawm magnetization. Peak tus nqi sib txawv thiab lub kaum sab xis sib txawv tau cuam tshuam rau kev ua haujlwm ntawm lub cev muaj zog, cogging torque, kub nce, thiab suab nrov. Ob qhov kev txwv tsis pub tuaj yeem hloov kho kom zoo dua ntawm kev tsim cov thev naus laus zis thiab kev sib nqus sib nqus. Tsis tas li ntawd, thaj chaw thiab lub luag haujlwm yuav cuam tshuam rau lub zog hluav taws xob (BEMP), ntsuas lub zog, thiab lub zog.
