ThermNet 1.8 release has more for motors

The upcoming release of ThermNet will allow for the simulation of heat exchange between the rotor and the stator, through the air gap. In this simulation model, the heat flux from any point on the surface of one body is proportional to the difference between the temperature at that point, and the average temperature on the surface of the second body. The constant of proportionality, which is under user control, may be a function of temperature and will, in general, depend on factors such as the width of the air gap and the speed of rotation. An energy balance is enforced so that all of the heat leaving one body surface is transferred to the other body.

Another important new feature of ThermNet 1.8 will be its capability to perform coupled transient-to-transient analysis. For example, using MagNet's Transient 3D with Motion solver and ThermNet's Transient 3D thermal solver, it is now possible to analyze temperature rise in different parts of an electrical machine due to winding and core losses.

Infolytica enters into a strategic partnership with SPEED

Electric machine designers who use University of Glasgow's SPEED software will now be able to combine its advanced CAD software for electric motors and drives, with the powerful calculations of MagNet, Infolytica's design & analysis software for low frequency electromagnetic devices. A link that was first developed by Infolytica Ltd in the UK is now part of a tightly integrated system that will fulfill all the current GoFER functions in SPEED. As well, MagNet is capable of returning the same files as PC-FEA to all SPEED programs for MatchFE and for further design calculations in SPEED. More developments are planned for the near future to further enhance the combined service of MagNet and SPEED to the worldwide community of electric machine designers.

Please note that examples of this new MagNet-SPEED link will be available shortly in our web site's Gallery section. One of these examples will feature a 4-pole, 15-slot, 1-barrier Interior Permanent Magnet Motor (IPM), with fractional winding. Click here for a preview.

MagNet 6.16.2

Once again, our developers have managed to make a significant improvement to MagNet. This latest enhancement will substantially increase MagNet's processing speed when analyzing models that contain many interdependent parameters. MagNet 6.16.2 should be available sometime in the following week.

News & Events

Infolytica to present at SMMA Fall Technical Conference

David Lowther, PhD, President, and Behzad Forghani, Vice President, Infolytica Corporation, invite you to join them at this year's SMMA conference, where they will be presenting a seminar titled "An optimization tool for electric motor design", on November 3, 2004: 1:00-5:00 pm. This seminar will focus on the practical uses of optimization based on electromagnetic field simulation for effective improvement of motor designs. Starting from an initial design that may contain even a large number of parameters, it will be shown how improvements are found and validated for robustness. Several motor design examples will be used to illustrate the operation of OptiNet, Infolytica's design optimization tool.

Mr. Forghani will also be giving a talk on "Dynamic Simulation of Electric Motors" on November 4, 2004: 4:30-5:00 pm.

MagNet training course

This course (scheduled for November 16 - 18, 2004) shortens the learning curve and helps you rapidly become productive with one of the most powerful 2D and 3D software tools available for the Electromagnetics' designer.

OptiNet training course

The OptiNet course will be held on Friday, November 19, 2004. This course combines tutorials, demonstrations and lectures where participants acquire a better understanding of optimization using OptiNet.
