Value of FEA
Is FEA effective in motor design?
This series has explained the issue of "Why is finite element method electromagnetic field analysis (hereafter FEA) effective in motor analysis?" Issue 1 discussed the use of FEA at the concept design and initial design stages for motors, and showed that use of FEA at the initial design stage allows high-speed investigation of design proposals with many degrees of freedom, which is difficult to calculate by hand. Issue 2 explained that, at the detailed design stage, FEA can be used for trial-and-error to economize on detailed designs. This final issue discusses the significance of FEA for detailed understanding of the phenomena that occur inside a motor.
As computer hardware and software becomes more advanced, finite element method electromagnetic field analysis (hereafter FEA) is being used more, and its real effectiveness in development facilities is growing.
However, if you talk to people who are not using FEA now, there are many who say things like "I've heard that FEA is good, but we can accomplish the same things with our current development process, so we don't need it," or "It seems like it would take a lot of time and effort to adopt it."
This series attempts to respond to the concern of "why is FEA effective in motor design?" We hope this helps you to understand the benefits of using FEA for better motor design.
In Issue 1, I discussed the use of FEA at the concept design and initial design stages in motor design. Here in Issue 2, I will present uses for FEA at the detailed design stage. The goal at this stage is to optimize design variables based on rough proposals determined at the concept and initial design stages, and then to settle on design parameters such as measurements, conditions, and material properties for the various parts. We will discuss effective use of FEM in design optimization at the detailed design stage, and how to analyze FEA results and apply them to designs.
Along with the progress in computers and software, finite element magnetic field analysis (FEA below) is being utilized in motor design and is actually producing results in development. On the other hand those not using FEA might be thinking, "I know FEA is good but evaluating will take effort and time so in the end a traditional design sheet will be quicker." In this series, we will explain "Why FEA is effective in motor design?". We would be happy if this is used as a reference for utilizing FEA and designing better motors.
FEA Commentary: What Advantages Does FEA Bring to Development?
The purpose of this session is to show the merit of using simulation for the design of induction heating apparatus. Please consider the merits of analysis when you try to improve your heating method.
I would like to clarify how much value there is in introducing finite element analysis (FEA) to the electrical equipment design field. In this issue, I will examine the ways in which FEA can be applied to transformers, and to large scale power transformers in particular. In general, FEA allows you to visualize physical quantities that cannot be seen by the naked eye and streamline your design process. This article is a must-read for those who have given up on FEA because they think that it takes too much time.
Effectiveness of FEA in the Development Process
This report introduces FEA's characteristics, which include an excellent analytical ability, in order to examine both the advantages they bring to the development process and the utilization methods for applying them. In this, the final issue, I will introduce applications to failure modes, which is a new way of using FEA. Using FEA allows us to obtain information that is not available through an actual device test. It can give us substantially greater insight into the device's performance.
Among those reading this magazine there are most likely some who think that, because they began development in an era when there was no FEA and their design process is already set in stone, there is no point in starting to develop with FEA at this late stage. There are also probably quite a few who are interested in FEA, but cannot picture how they would actually be able to extend it to the design process.
In this issue, by taking another look at the product development process up to the present, I would like to exhibit the fact that there are places in which FEA is actually able to play a large role in various development process situations, including design.
Electromagnetic field finite element analysis (FEA) has been rapidly expanding as a tool used in the development process over the last 15 years.
The application of FEA varies based on the needs of each development process, but why has FEA expanded so rapidly as a tool for development? In addition, what are the advantages of using FEA in the development process?
Impact of FEA on the Design Process will introduce how FEA has effected the development process from multiple perspectives over the next year.
