Magnetic gear and coupling using permanent magnet.
Journal of the Magnetics Society of Japan, 1987 Recently, permanent magnets have shown excellent practical performance characteristics. A description is given of a magnetic device with rotational ratio n constructed using a permanent magnet. When n ≠ 1, it operates as a magnetic gear and when n = 1, it operates as a magnetic coupling. As a magnetic gear, we used SmCo5 for the permanent magnet.

Small, EarlyView.ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

steel research international, EarlyView.Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse. To

Artificial Organs, EarlyView.This study aims to evaluate the potential of a multistage pump design to enhance hemocompatibility in left ventricular assist devices. We found that the two‐stage concept offers favorable hemolysis measures compared to single‐stage designs, as the reduction in peak shear stresses outweighs the disadvantage associated with prolonged residence time ...
