This book focuses on how to use magnetic material usefully for
electrical motor drive system, especially electrical vehicles and power
electronics. The contents have been selected in such a way that
engineers in other fields might find some of the ideas difficult to
grasp, but they can easily acquire a general or basic understanding of
related concepts if they acquire even a rudimentary understanding of the
selected contents.The cutting-edge technologies of magnetism are also
explained. From the fundamental theory of magnetism to material,
equipment, and applications, readers can understand the underlying
concepts. Therefore, a new electric vehicle from the point of view of
magnetic materials or a new magnetic material from the point of a view
of electric vehicles can be envisioned: that is, magnetic material for
motor drive systems based on fusion technology of an electromagnetic
field. Magnetic material alone does not make up an electric vehicle, of
course. Other components such as mechanical structure material,
semiconductors, fuel cells, and electrically conductive material are
important, and they are difficult to achieve. However, magnetic material
involves one of the most important key technologies, and there are high
expectations for its use in the future. It will be the future standard
for motor-drive system researchers and of magneticmaterial researchers
as well. This book is a first step in that direction.
