Improved Iron Loss Prediction in Transformers

This example shows that a MagNet time-harmonic solver can predict the same iron loss as a transient solver within a fraction of the time. A 90 % reduction in solution-time was achieved in this example of 100 kVA single-phase distribution transformer.

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.

Vibrations in Electric Motors

In this case study we consider a 4-pole-24-slots electric motor, which is modeled in MagNet by a quarter section. The rotor rotates with a frequency of 30 Hz and the coils exhibit an odd parity. We are interested in the vibrational behavior of the full stator.

From Electromagnetic Forces to Acoustics Part 1

The electromagnetic forces computed by MagNet can be transferred by the FSIMapper to structural analyses. For transient MagNet results additionally a Fourier transformation can be applied in order to generate the loading for structural vibration analyses. In this way the engineer is able to investigate the resulting vibrations and noise emissions. Also partial MagNet models (with even or odd periodicity) are supported to be mapped on full structural models. The functionality is presented using some examples. (This was originally presented at Engage 2015).

Toyota 2010 Prius traction motor analysis using MotorSolve

The engineers at NTRT at OakRidge National Labs have carefully tested the 2010 Prius and completely reverse engineered the power train system and taken extensive test data.. The content of this presentation outlines the results of a complete analysis of the 2010 Prius traction machine using MotorSolve and compares the results with the test data from the NTRT report. The complete machine performance results from MotorSolve including a thermal analysis and efficiency plot comparison are presented. (This was originally presented at Engage 2015).
