Switched reluctance motors work on the principle of reluctance torque. The stator and rotor will interact to minimize the reluctance for the flux path. This application simulates the behavior of the motor when the stator winding is excited with a step voltage and when the rotor is at a ... Mehr lesen
This model illustrates the working principle of an electrodynamic wheel (EDW) magnetic levitation system. EDW magnetic levitation system consists of rotating and/or translationally moving permanent magnet Halbach rotor above a passive conducting guideway/track. Eddy current is ... Mehr lesen
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 ... Mehr lesen
In this model, a linear magnetic gear system with a gear ratio of 11:4 is modeled. The liner magnetic gear is assumed to be infinitely long with the modular structure that is repeating on either side. Only a single modular section is modeled by using the customized linear periodic ... Mehr lesen
Several different approaches to optimizing a ten-turn axisymmetric coil are presented. First, the current in each turn is adjusted with the objective of having a uniform magnetic flux density along the centerline. Second, the currents are adjusted to minimize power dissipation with a ... Mehr lesen
This model simulates an LED that emits in the infrared part of the electromagnetic spectrum. The device structure is made up of a single p-n junction formed by a layer of p-type doping near the top surface of an otherwise n-type wafer. This kind of device geometry is simple and cheap to ...

This model presents the transient modeling of a coaxial magnetic bearing using permanent magnets. The coaxial magnetic bearing is advantageous over the conventional mechanical gear mainly because of minimum noise, maintenance free operation, overload protection and physical isolation ... Mehr lesen
The multipole expansion is a powerful tool for analyzing electromagnetic waves scattered by small objects. In the expansion, the scattered field is represented as a superposition of the fields created by a finite set of point multipoles. Each point multipole is connected to a unique ... Mehr lesen
Das Modell analysiert die Modenausbreitung in einem Nano-Schlitzwellenleiter. In einer Schlitzwellenleiterkonfiguration sind zwei Platten mit hohem Brechungsindex (~3,48) neben dem Schlitz mit niedrigem Brechungsindex (~1,44) angeordnet. Die Modenanalyse wurde an einem 2D-Querschnitt ... Mehr lesen
This model demonstrates three different ways to find the eigenfrequencies of a rectangular metallic cavity. The first method uses an eigenfrequency study step together with the Electromagnetic Waves, Beam Envelopes interface. Here, it is important to define a wave vector for the physics ... Mehr lesen
