The effects of the inverter supply are taken into account by coupling Flux2D with Matlab/Simulink. The results are compared with those obtained from noise measurements performed on the studied motor.

Using Analytical Approach with Finite Element Analysis for Coupling Magnetic and Thermal Analysis for Motors

Thermal analysis is a key factor when designing motors. We propose to link the studies of electromagnetic and thermal aspects in transient application with Finite Element Method (FEM) to represent the thermal state of motor with higher accuracy. As electromagnetic response time is different of thermal response time, an original method is used for extracting average values on one magnetic period of losses (Joule and iron losses), and to use them as input for the transient thermal analysis. So, the temperature in different parts of the motor is extracted, and brought back as input for the next electromagnetic computation.

Increasing the Customer Value of Structural Designs Using HyperStudy and Topology Optimization While Considering Manufacturing Constraints

This was a 2010 Americas HTC Presentation given by Steve Reagan from L&L Products. In the demanding environment seen in today's markets, continual innovations driving increasing levels of customer value are key. The use of topology optimization with the inclusion of manufacturing constraints was critical to the achievement seen in this project and was made possible through the close product/process integration available through the HyperWorks tool suite. In this presentation, Dr. Reagan shows how HPC, RADIOSS, HyperStudy, and OptiStruct were employed to drive material cost down while maintaining product performance.

HyperMesh and HyperView customization for thermal analysis of engine systems

This was a 2010 Americas HTC Presentation given by Emil Chouinard from GE Aviation. GE Aircraft Engines has many NPI (new product initiative) programs that rely on accurate and timely thermal analysis, as temperatures are critical to accurate estimates of hardware life. HyperMesh and HyperView have been customized as the pre and post processing tools, respectively, for thermal analysis of engine systems. The single database with relational data management greatly reduces modeling errors and results in Engineers being able to focus on the physics of the problem instead of data management.
