DYNAMIC COMPACTION OF PURE COPPER POWDER USING PULSED MAGNETIC FORCE H.P. Yu1,C. F. Li1 (1.National Key Laboratory for Precision Hot Processing of Metals, Harbin Institute of Technology, Harbin 150001, China) Abstract:The compaction of pure Cu powder was carried out through a series of experiments using dynamic magnetic pulse compaction, and the effects of process parameters, such as discharge......
to the corridor of magnetic force lines, therefore only an effectively closed magnet array structure can form a relatively uniform and closed discharge lane. The main reasons for electrons'' releasing from magnetic confinement are the vertical magnetic repelling force as well as a more and more weak confinement action in outer range etc. The dominant reasons for a comparatively low increase of substrate''s......

(2012) 19: 357-364 DOI: 10.1007/s11771-012-1012-7 Optimization of rotor shape for constant torque improvement and radial magnetic force minimization CHO Gyu-won, WOO Seok-hyun... magnetic force; cogging torque 1 Introduction An interior permanent magnet synchronous motor (IPMSM) is a mechanically strong structure with permanent magnets embedded in rotor, and the generating torque per......
range of magnetic force number from 0 to 1000. Vertical walls of the square cavity were heated differentially while the horizontal walls were assumed to be adiabatic. Distributions of the flow... with the augment of magnetic force number. Under gravitational condition, two-cellular structure only occurs when the magnetic field is relatively strong, and the average Nusselt number decreases at first......
rectangularity. It is found that the sintered NdFeB magnet has relatively high magnetic performance of Br=12.17kGs, jHc=13.52kOe and (BH)max=34.71MGOe. The sintered NdFeB sample was examined by magnetic force...; magnetic force microscope; domain structure; rare earths; [全文内容正在添加中] ......
