Classical eddy current losses in Soft Magnetic Composites
1 a Corresponding author: [email protected] 2 This paper deals with the problem of loss evaluation in Soft Magnetic Composites (SMC), focusing 2 on the classical loss component. It is known that eddy currents can flow in these granular materials at 3 two different scales, that of the single particle (microscopic eddy currents) and that of the specimen 4 cross-section (macroscopic edd...
متن کاملStator Core with Slits in Transverse Flux Rotary Machine to Reduce Eddy Current Loss
This paper presents an eddy current loss analysis for a transverse flux rotary machine (TFRM) with laminated stator cores, which consist of inner and outer cores whose laminated directions are perpendicular to each other. Although the TFRM is laminated to reduce eddy current losses, it still exhibits rapidly increasing core losses as the frequency increases. To solve this problem, slits are int...
متن کاملEddy Current Losses in Transformer Windings and Circuit Wiring
Skin Effect Figure 1 shows the magnetic field (flux lines) in and around a conductor carrying dc or low frequency current I. The field is radially symmetrical, as shown, only if the return current with its associated field is at a great distance. At low frequency, the energy in the magnetic field is trivial compared to the energy loss in the resistance of the wire. Hence the current Introductio...
متن کاملEvaluation of Eddy Losses Due to High Current Leads in Transformers Using a Subproblem Method
A subproblem finite element method is developed for evaluating the eddy losses due to high current leads in transformers. The structural component of the transformer is modeled with classical volumetric elements or more efficiently with a thin shell model (surface impedance technique). Tools are then developed to correct the inaccuracies near edges and corners inherent to thin shell models for ...
متن کاملReviewing the Impact of FACTS Devices to Reduce Losses and Voltage Profile in the Pool Market
Abstract: In this paper, a generalized Lagrangian-based algorithm (TRALM) and gravitational search algorithm (GSA) are used to solve the Optimal Load Distribution Problem (OPF) in the presence of FACTS equipment. Four TCSC, TCPST UPFC and SVC equipment’s have been tested. Modeling of FACTS equipment is based on power injection method. To optimally manage production, losses and voltage profiles,...
