چکیده
We discuss the relevance of several finite-element formulations for nonlinear systems containing high-temperature superconductors (HTS) and ferromagnetic materials (FM), in context a 3D motor pole model. The are evaluated terms their numerical robustness efficiency. propose coupled h-phi-a-formulation as an optimal choice, modeling problem with a-formulation FM h-phi-formulation remaining domains. While maintaining low number degrees freedom, guarantees robust resolution strongly reduces iterations required handling nonlinearities HTS compared to standard formulations.

What Project Should I Choose?
This work analyzes the distribution of past CS229 projects by applying hierarchical agglomerative clustering. The clusters reveal which topics are very popular and which topics are more unique. Tracking the clusters over time also provides insight into how student projects have shifted over time. This knowledge will help future students select interesting and unique projects.

متن کامل3-D Magnetostatic With the Finite Formulation
The paper presents the solution of a three-dimensional (3-D) magnetostatic problem using the finite formulation of an electromagnetic field. Two different approaches, based on a primal-dual barycentric discretization of the 3-D space, are presented, considering as unknowns either the magnetic fluxes or the circulations of the vector potential. Results on simple reference configurations are repo...
متن کاملA New Skewed-Rotor-Pole Switched Reluctance Motor Design
This paper considers a new switched reluctance motor (SRM) structure aiming at high starting torque with low volume. For some applications such as EVs (Electrical Vehicles), the motor volume and starting torque is a critical point in its design. In many methods, reducing the motor volume causes reduction in starting torque and decreases the motor efficiency. Unlike conventional SRMs, the rotor ...

This paper presents 2D and 3D modeling of hysteresis motor using high temperature superconducting element Yttrium Barium Copper Oxide (YBCO) in the rotor. These hysteresis motors aim to improve the performance in comparison with that of conventional hysteresis motors. Various performance parameters of high temperature superconducting hysteresis motor are computed from the proposed 2D and 3D mod...
