Investigation of Superconducting Linear Synchronous Motor Propulsion Control via an Exact Mathematical Model

Numerical Design Methodology for an All Superconducting Linear Synchronous Motor

One potential advantage of the application of superconducting materials in electrical machines is the possibility to build lighter and compact devices by removing iron. These machines find applications, e.g., in systems where cryogenics is already available, or in naturally cryogenic environments. The design of motors with high temperature superconductors (HTS) presents issues unconsidered in c...

Mathematical Model of Unsteady Groundwater Flow Through Aquifers and Calibration Via a Non-Linear Optimization Technique

In this study, the general partial differential equation of unsteady groundwater flow through non-homogeneous and anisotropic aquifer was solved by the fully implicit finite difference method with control volume approach. The calibration of permeability and storage coefficients as model parameters was performed by a transformation technique and application of Powell's non-linear optimization me...

Mathematical Analysis for Response Surface Parameter Identification of Motor Dynamics in Electric Vehicle Propulsion Control

2D Analytical Modeling of a Wholly Superconducting Synchronous Reluctance Motor

An analytical computation of the magnetic field distribution in a wholly superconducting synchronous reluctance motor is proposed. The stator of the studied motor consists of three-phase HTS armature windings fed by AC currents. The rotor is made with HTS bulks which present the specificity to have a diamagnetic behavior under zerofield cooling. The electromagnetic torque is obtained by the int...
