Micrometric non-contact position magnetoimpedance sensor
(Elsevier, 2018)
info:eu-repo/semantics/article,
In this work a sensitive micrometric non-contact position sensor based on the Giant MagnetoImpedance effect (GMI) is analyzed. A nearly zero magnetostrictive CoFeSiBCr wire was employed as sensor nucleus. The sensing ...
Thrust actuator with passive restoration force for wide gap magnetic bearings
(Elsevier, 2019)
info:eu-repo/semantics/article,
Active thrust magnetic bearings provide an axial force to balance the moving parts of machines. However, most devices produce null or unbalancing passive forces. Furthermore, reported designs usually feature very small ...
