[Mark Rehorst] has been on the hunt for the perfect 3D printer cooling fan and his latest take is a really interesting design. He’s printed an impeller and housing, completing the fan using a hard ...
A motor — or a generator — requires some normal magnets and some electromagnets. The usual arrangement is to have a brushed commutator that both powers the electromagnets and switches their polarity ...
According to the National Research Council of Science and Technology, the Korea Institute of Machinery & Materials (KIMM) has developed magnetic 3D printing technology capable of manufacturing ...
3D printing equipment with variable laser module for microstructure control. Credit: Korea Institute of Machinery and Materials (KIMM). Scientists in South Korea have made an exciting breakthrough in ...
Abstract: We investigated numerically the characteristics of axial unbalanced magnetic force (UMF) due to axial magnetic design in the spindle motor of a hard disk drive (HDD). The HDD spindle motor ...
STMicroelectronics' compact and highly-integrated hard disk-drive Motor Controller targets 1.8-in. and sub-1.8-in. drives used in portable products such as MP3 and video players. STMicroelectronics’ ...
Abstract: This paper investigates the dynamics and NRRO of a 2.5" HDD by using FEM, modal testing and runout analysis. Most frequency components of NRRO are generated by the defects of ball and ...
Mitsubishi showed them yesterday, and Sony followed [JP] today: All-in-one LCD TVs that feature 3D capability and come with built-in Blu-ray recorders and HDDs. The so-called BRAVIA 2 KDL series ...
