Sib Nqus Field Distribution of Ring Magnets

Kev sib nqus ncej ntawm lub nplhaib hlau nplaum feem ntau muab faib ua ob hom: axial magnetization thiab radial magnetization. Axially magnetized hlau nplaum muaj ncej nyob rau ntawm ob qho kawg ntawm lub nplhaib, nrog ib kawg yog N ncej (sib nqus flux ceev kwv yees li 0.5-1.2T) thiab lwm qhov kawg yog S ncej. Hom no yog tsim rau cov ntawv thov uas yuav tsum muaj axial magnetic teb, xws li lub cev muaj zog stators. Radial magnetized hlau nplaum muaj cov ncej faib rau sab hauv thiab sab nraud (N ncej ntawm sab hauv ncig / S ncej ntawm sab nraud ncig, lossis rov ua dua, nrog qhov sib nqus flux ntom ntawm 0.3-0.8T). Hom no feem ntau pom muaj nyob rau hauv cov sensors thiab cov khoom sib nqus sib nqus thiab tuaj yeem ua tiav ib qho kev faib tawm radial magnetic teb.
