MEIDENSHA CORPORATION
Stimulating the Expansion and Reinforcement of the Business Domain with
JMAG
The Meidensha Corporation, whose business ranges vary from heavy electric
machinery to industrial electric systems, was established 113 years ago.
The technology of its products is mainly founded in rotation machines.
The JSOL Corporation's electromagnetic field analysis software, JMAG, has
stimulated technological innovation, supporting product development by
providing a tool capable of achieving higher efficiency, higher output,
and establishing highly precise control technology for its products. Electromagnetic
field analysis software is also at the forefront of development for new
technologies that require advanced solutions for environmental conservation.
Mr. Yamada, Executive Officer and General Manager of the New Product Development
Group, Mr. Nomura, Senior Fellow, Mr. Watanabe, Senior Engineer of the
New Product Development Planning and Management Department, and Mr. Matsuhashi,
Manager of the Analytic Simulation and Advanced Control Technologies Section,
discuss why they decided to implement JMAG and the benefits of using it.

- The Meidensha Corporation has manufactured and sold electrical devices
such as generators, transformers, and electric distribution systems as
well as contributed to the social infrastructure, such as water treatment
devices and control systems for water supply and sewerage systems, various
electric components for manufacturing equipment, and computer systems since
it was established in 1897. What advantages does the Meidensha Corporation
have?
Mr. Yamada Our technology and products are fundamentally based on "rotation"
or in other words "rotating machines." The phenomena of "rotation"
seems simple, but in fact it is quite profound. For example, when motors
start or brake, the necessary force, rotation speed, and the type of control
depend on the type of load.
A motor-driving system usually requires a motor itself and an inverter
to control the speed of the motor by the current supplied. It wouldn't
be a high quality system if either the motor or the inverter did not work
well. The motor has to respond quickly and accurately to the control of
the inverter, and the inverter has to control the motor by accurately detecting
the speed and output.
Motors and inverters can also be bought separately and combined. However,
the Meidensha Corporation earned the trust of its customers because we
are able to produce high-performance products by developing the motor and
inverter as one unit.
Our motors and inverters are comprehensively investigated at each stage
of development by a team of development engineers. This allows us to resolve
any problem with assembly, etc., at the earliest stage of development.
We can offer products that can be used easily by our customers because
we are able to examine the products based on the actual circumstances that
our customers will be using them.
