Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Reduction of force ripples in linear motors
, 2014 The influence ofhigher field harmonics of permanent magnets, and asymmetry of flux linkages according to the phase shift on the value of force ripples in linear motors is studied. The solution to this problem is based on a higher field harmonics analysis in the active zone of a two-phase permanent-magnet cylindrical linear motor.
