Multi-Turn Coil Winding around a Ferromagnet

A demo model of a 50 Hz AC coil wound around a ferromagnetic (linear) core. The model is intended as a tutorial to show how to create a relatively complex geometry and set up the new Multi-Turn Coil features for the simulation. The model requires the Design module to fillet the edges of ... Saiba Mais

Mutual Inductance and Induced Currents in a Multi-Turn Coil

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. The secondary coil is modeled using a homogenized approach which does not explicitly consider each turn ... Saiba Mais

Induction Currents from Circular Coils

A time-varying current induces a time-varying magnetic field. The magnetic field induces currents in neighboring conductors. The induced currents are called eddy currents. In this model, the phenomenon is illustrated by a time-harmonic field simulation as well as a transient analysis, ... Saiba Mais

Computing the Resistance of a Wire

Every electrical device has some resistance. That is, when a voltage difference is applied across any two terminals of the device, there will be a directly proportional current flow. This model demonstrates how to compute the resistance of a short section of copper wire. The convergence ... Saiba Mais

Transient Modeling of a Capacitor in a Circuit

A transient model of a capacitor is solved in combination with an external electrical circuit. The finite element model of the capacitor is combined with a circuit model of a voltage source and a resistor. A step change in voltage is applied, and the transient current through the ... Saiba Mais

Modeling of an Electric Generator in 3D

These models demonstrate how to set up a sector model of rotating machinery both in 2D and 3D using the *Rotating Machinery, Magnetic* interface in COMSOL Multiphysics®. The stator in these permanent magnet AC generator examples consists of a stator winding backed by an iron core. The ... Saiba Mais

Electromagnetic Forces on Parallel Current-Carrying Wires

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. Saiba Mais

Inductive Heating of Copper Cylinder

The induced currents in a copper cylinder produce heat that in turn change the electrical conductivity. This means that the field propagation has to be solved simultaneously with the heat transfer through the cylinder and surrounding system. This model shows this coupling between eddy ... Saiba Mais

Frequency Domain Modeling of a Capacitor

A capacitor with an applied sinusoidally time-varying voltage difference is modeled. A wide frequency range is considered and the impedance of the device is computed. Solver accuracy is addressed. The relationship between the frequency domain impedance and the steady-state capacitance ... Saiba Mais
