Analysis of a Boost Converter Inductor

MagNet's suitability is demonstrated by using it to analyze the inductor of a 27 kW boost converter that steps-up an electric vehicle's battery voltage from 200 V to 200 - 650 V range.

Demonstrating a variation of the MagLev suspension system

The performance of this machine is simulated using MagNet’s Transient 3d with Motion solver. The vehicle, consisting of the aluminum channel with payload, is given six degrees of freedom so that it is free to rotate about the roll, pitch and yaw axes and so that it is also free to move in all three dimensions (up-down, left-right, forward-backward). The vehicle is initially resting on supports 1 cm above the track, which is 0.5 cm below its equilibrium position when the track is energized.

Optimization Of A Die Press (T.E.A.M. Problem 25)

In this device, the objective is to find the size of the inner die mold and the shape of the outer die mold in order to obtain the desired magnetic field in the cavity shown in the figure. Using MagNet and OptiNet, the optimal radius for the inner mold and the elliptical shape for the outer mold can be determined given specified design objectives.

Simulating a Cyclic Electron Path in a Magnetron

The trajectory of an electron in a magnetron can be simulated based on the fields present in the space between the cathode and the anode.Using MagNet, ElecNet and the Trajectory Evaluator, the electric and magnetic field strengths are adjusted so that the path of the electron does not reach the anode and forms a cyclic trajector.

Simulating Multiple Moving Parts of a Magnetic Gear

This example shows simulations of a magnetic gear system and it’s performance. In this example, the magnetic planetary gear assembly is analogous to an equivalent mechanical system, with the inner rotor acting as the sun gear, the outer rotor as the ring gear, and the stationary steel pole pieces acting as planetary gears (it is the magnetic field that spins, not the pole pieces themselves). There are 2 pole pairs on the inner rotor and 5 pole pairs on the outer rotor, making the gear ratio of this assembly 2.5:1. The model is shown here.
