A vessel traveling on the surface or under water gives rise to detectable local disturbances in the Earth’s magnetic field. These disturbances can be used to trigger weapon systems. The magnetic signature of a ship can be reduced by generating a counteracting magnetic field of suitable ... En savoir plus
Silicon carbide (SiC) epitaxial furnaces are a specialized equipment for the production and preparation of SiC epitaxial wafers. This example model demonstrates the process of preparing an SiC epitaxial wafer based on the physical vapor transport (PVT) method in a furnace. This involves ... En savoir plus
In this tutorial, a PM motor with 10 rotor poles and 12 stator slots is modeled in 2D, to capture the torque ripple over an electrical period and map the volumetric loss density in the rotor and stator iron. En savoir plus
The mutual inductance and induced currents between a single turn primary and twenty turn secondary coil in a concentric coplanar arrangement is computed using a frequency domain model. Each turn of the secondary coil is modeled explicitly. The results are compared against analytic ... En savoir plus
This tutorial model explains how to extract lumped matrices by means of the Stationary Source Sweep study. The capacitance matrix of a five-terminal system is used to infer the position of a metallic object similar to real-world capacitive position sensors. The example illustrates the ... En savoir plus
Power inductors are a central part of many low-frequency power applications. They are, for example, used in the switched power supply for the motherboard and all other components in a computer. Computer simulations are necessary in the design of such inductors. This model calculates the ... En savoir plus
This model shows a setup of two parallel wires with a constant current running through both. Their cross-sections are successively reduced until a set force per unit length is reached. En savoir plus
A magnetic brake consists of a permanent magnet, which induces currents in a rotating copper disk. The resulting eddy currents interact with the magnetic flux to produce Lorentz forces and subsequently a braking torque. This 3D problem is solved using a stationary formulation for the ...
