Implementing JMAG

- How will the Meidensha Corporation expand their business in the future and what role will JMAG play?

Mr. Yamada The Meidensha Corporation created a medium-term management plan, "POWER 5," which is a five year plan starting from fiscal 2009. In this medium-term plan, we are striving to expand our business in 5 areas that contribute to a low-carbon society, such as motors and inverters for electric vehicles. Each of these business areas relates to rotating machine technology in some way, such as motors. The direction of technology in the future points to continuous technological development for rotating machines. In addition, innovation of products contributing to environmental conservation is also indispensable.

In the future, design methods accounting for the biodegradability of products, which is the last stage of their life cycle, will be necessary to meet the challenges in reducing the total environmental burden. PM motors, for example, will probably need to be innovatively designed so that the permanent magnets of the rotor can be recycled easily. Heavy electric equipment and industrial electric systems, just like appliances, require recycling control methods founded in product liability.


Mr. Watanabe Product development has to be environmentally friendly as well as consumer friendly, not simply by quantitatively understating the environmental burden of the products, but by establishing a product life cycle management system. Therefore, it is necessary to know the performance of products at an early stage of development or even at the stage of concept. And it means that simulation becomes more and more important.

I have realistic expectations that the calculation speed will continue increasing and the range of analysis will expand to thermo-fluid analysis. However, stepping back for a wider perspective, I would love to see functions to calculate the CO2 emissions of a product at the analysis stage and increase the percentage of materials used in products that can be recycled.

JMAG is evaluated highly as one of the major leaders in magnetic field analysis software since its release in 1983. And for this reason, I expect JMAG to continue being a software that engineers can rely on.
