چکیده
Additively manufactured soft magnetic Fe-3.7%w.t.Si toroidal samples with solid and novel partitioned cross-sectional geometries are characterized through measurements. This study focuses on the effect of air gaps annealing temperature AC core losses at 50 Hz frequency. In addition, DC electromagnetic material properties presented, showing comparable results to conventional other 3D-printed, high-grade, materials. The magnetization 1.5 T was achieved 1800 A/m, exhibiting a maximum relative permeability 28,900 hysteresis 0.61 (1 T) 1.7 (1.5 W/kg. A clear trend total loss reduction observed in relation segregation specimen topology. lowest were measured for four internal annealed 1200 °C, 1.2 5.5 is equal an 860% 1 510% compared bulk-printed material. Based findings, advantages disadvantages printed air-gapped structures discussed detail.

متن کاملModel Order Reduction for Rotating Electrical Machines
The simulation of electric rotating machines is both computationally expensive and memory intensive. To overcome these costs, model order reduction techniques can be applied. The focus of this contribution is especially on machines that contain non-symmetric components. These are usually introduced during the mass production process and are modeled by small perturbations in the geometry (e.g., ...
متن کاملSoft Magnetic Composites for AC Machines - A Fresh Perspective
Soft magnetic composites (SMCs) have opened up new possibilities for the design of both DC and AC machines. Since SMCs are isotropic, machine topologies such as claw pole machines, transverse flux machines and the like, which have three dimensional flux density patterns have attracted the most attention. Very little effort has gone into improving the performance of conventional AC machines such...
متن کاملOverview and Comparison of Iron Loss Models for Electrical Machines
One important factor in the design process and optimization of electrical machines and drives are iron losses in the core. By using new composite materials and low-loss electrical SiFe steels, the losses in the magnetic ux conducting parts of the machine can be reduced signi cantly. However, it is necessary to have accurate but also easy implementable iron loss models to take the loss e ects in...
