New release of MagNet, ElecNet, ThermNet and OptiNet The newest
releases of MagNet,
ElecNet,
ThermNet
and OptiNet
Improved meshing with latest releases Two significant improvements to the mesh generator have been included in the latest versions of MagNet, ThermNet and ElecNet. Automated mesh refinements in 2D are handled more efficiently, resulting in significantly faster runtimes. Example: Transformer Bushing  To demonstrate, consider the following transformer
bushing model (click on image to view full model). The following
analysis will examine the variation across the bushings. Using ElecNet 6.16.1, the solve time was 31 minutes, 12 seconds.  Shown here is the electric field |E| shaded plots.Performing the same simulation with ElecNet 6.17, the solve time was 9 minutes, 53 seconds - more than three times faster. The increase in efficiency will vary depending on the model and mesh complexity. Mesh Refinement Component Control Mesh refining on specific components can also be enabled or disabled in either 2D or 3D. Users can improve efficiency by selecting different mesh refinements based on the sensitivity of different components in a device. .back to top General springs for dynamic mechanical effects Users simulating the simplest to most complicated electromechanical devices have continuously praised the versatility permitted with MagNet’s support of arbitrary motion (multiple degrees of freedom). Taking full advantage of such power is easy with improved spring modeling that calculates the dynamic mechanical effects of any two spring-connected components, commonly found in many magnetic suspension systems or complex actuators. back to top New Extension Pack Consolidates Specialized Tools The new Extension Pack is a free software bundle available for all maintained MagNet, ElecNet and ThermNet customers. Users can easily install several specialized tools for enhanced analysis capabilities with one quick download, including: • The 3D Coil Creator • The Parameter Manager • The Field Integrator • More Please visit the Documentation Center for more details. Maintained customers can download the latest Extension Pack from the download section of our Online Customer Support Center. back to top Vector Control supported in Plug-In for Simulink© facilitates design of energy efficient motors Complex control algorithms, such as vector controlled circuitry, are now supported when using the MagNet Plug-In for Simulink for co-simulations between an electric machine and control logic. Load has been added to the existing voltage and current feedback parameters when coupling the two packages for a powerful joint analysis to characterize the performance of the entire device, facilitating the design and analysis of newer energy efficient types of brushless dc and induction motors. back to top New B-H data processing worksheet An updated B-H data validation worksheet, one of many free utilities in the Documentation Center, is now available for download. Created to assist users’ input custom material data in MagNet, the newest version improves handling of nonlinear B-H data. For a complete list of recent changes, click the What’s New button from the Documentation Center home page. back to top Design ExamplesSwitched Reluctance Motor OptimizationThis example demonstrates how OptiNet searches for the improved design of a 8/6 SRM to maximize the torque generated while conforming to manufacturing and operating constraints.

Read the full press release from Webcom > Infolytica will be presenting the following paper at M&D 2008: Automated Design of Multiphase Switched Reluctance Machines A fully automated design algorithm is implemented for SRMs. A minimum number of inputs that specify the performance criterion of the motor are used to initiate the design process and no analytic approximations are made in subsequent steps. The design process presented here is demonstrated for the case of an 8/6 SRM and the results are compared with those from an industrial 8/6 SRM. View the entire conference program > back to top |
