Effectiveness of FEA in the Development Process
Issue 1 Prevalence and background of FEA

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?

Issue 2 Reproducing Phenomena Authentically using FEA

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?

Issue 3 FEA Expansion to the Product Development Process

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.

Final Issue Failure Mode Simulation Using FEA

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.

FEA Commentary: What Advantages Does FEA Bring to Development?
Applying JMAG to Power Transformer Designs - Preventing Insulation Breakdowns Ahead of Time -

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.

The Goal of Induction Heating Analysis

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.

Is FEA effective in motor design?
Issue 1 Let's utilize it in initial design

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.

Issue 2 Making Use of FEA in Detailed Design

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."

Is FEA effective in motor design?
Issue 3 FEA for Understanding Detailed Phenomena

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.
