The need for high performance magnets has dramatically increased in recent years to meet the demands of modern electronics used both commercial clean energy and consumer products. Wind especially because unique large power density conversion efficiency needs powertrains require. Exciting new materials that these requirements include Nd/DyFeB, SmCo, SmFeN-based permanent magnets. To reduce waste production, manufacturing techniques like compression molding are necessary. work presented here...
Bimodal particles of NdFeB and SmFeB yielded high-density bonded magnets. The energy product 20 MGOe with 81 vol% magnet loading was demonstrated.
Newly developed high thermal conductivity polymer composite 3D printing filaments are used to characterize the properties as a function of print orientation. The printed part is anisotropic and varies by 2–6 times depending on direction - demonstrating higher in deposition (in-plane) than two directions perpendicular (cross-plane through-plane). Therefore, path planning greatly affects overall heat dissipation rate performance sink. Traditionally, slicers generate paths based solely...
Anisotropic bonded Nd2Fe14B (NdFeB) magnets in a polycarbonate (PC) binder matrix are fabricated into near-net shape using compression molding process. The weight fractions (w.f.) of NdFeB PC 20, 50, 75, 85 and 95% compared to the twin screw extruder with 50 75% respectively. density batch mixed was 5.34 g/cm3 magnetic properties are, intrinsic coercivity Hci = 942.99 kA/m, remanence Br 0.86 T, energy product (BH)max 120.96 kJ/m3. tensile range 27-59 MPa, displaying higher strength that...
