Infolytica Announcement #31
September 9, 2005
Product News
Latest version of Infolytica's design optimization tool, OptiNet 2.1, is released
The new OptiNet release comes equipped with a wider variety of objective/constraint functions, an expanded list of built-in functions for expressions, and re-usable expression variables. OptiNet 2.1 also comes with updated tutorials that address some real world examples. To obtain more information or to arrange a web demo of OptiNet, please contact one of our representatives by email at info@infolytica.com or by phone at 514-849-8752.
The Design Optimization category of the Gallery section has recently added two excellent examples (please see below) of OptiNet.

Ensuring Electric Machine Efficiency with MagNet and OptiNet
The task of the machine designer--a tireless effort to optimize torque ripple, running torque, efficiency, cost and a whole host of other factors--is now made easier with the latest software releases from Infolytica. In this example, MagNet and OptiNet are used to optimize an IPM (interior permanent magnet) machine, with the goal of minimizing the torque ripple, while maintaining a minimum running torque and ensuring that the back EMF does not exceed the supply voltage.Advanced Optimization of an IPM (Interior Permanent Magnet) Machine
This example looks at the optimization of a 3-phase, 4-pole single-barrier IPM (interior permanent magnet) using the combined power of MagNet (as the core solution engine) and OptiNet (as the optimizer). The goal is to optimize the motor's performance with respect to a reasonably realistic and complex objective function by changing a few simple geometric parameters (the size and position of the permanent magnets) and the advance angle (angle between the d-axis and the stator field). OptiNet and Magnet allow for the simple setup of such a model using its rich library of built-in constraints and objective functions, full parameterization of models and close coupling between both packages.Core Loss and Efficiency Calculations with Infolytica software
Magnetic losses (also known as iron losses or core losses) are an area of growing interest in fields such as advanced electric machines and transformers. This Gallery page demonstrates how Infolytica's MagNet and ThermNet software applications can give you more accurate results for both thermal and magnetic simulations.
Case Studies
Three separate case studies/ tutorials that examine a brushless DC Motor using MagNet's 2D solvers and a couple of specific purpose tools. The Air Gap Flux Calculator is used for the extraction of the radial air gap flux data and determines its harmonic content through Fourier Transform. The Cogging Torque Calculator allows users to enter the desired skew angle (in degrees), and the number of poles and slots. The tool can be used to generate a graph of the cogging torque for both the original and skewed machines:
