The article presents information on the International Magnetics Conference 2005 held in Nagoya, Japan. The conference was of outstanding scientific and technical quality. Altogether there were 1058 presentations given at the conference. These were strictly selected by the Program Committee from the 1527 digests and nominations that were submitted. After the conference, a total of 817 manuscripts were submitted for consideration for publication in this volume. This was a much heavier burden than anticipated for the editors of Intermag 2005. In order to avoid any delays, two publications teams were set up: Higashi and Nishi.

For the design of an Interior Permanent Magnet (IPM) motor with small torque ripple and large driving torque, the optimal design method called the ON/OFF method is attractive, because a new magnetic circuit, which we could not imagined beforehand, may be obtained. In this paper, a non-parametric optimization technique to find a new magnetic circuit which minimizes a torque ripple and maximizes a driving torque of IPM motor is examined. The effectiveness of the ON/OFF method for the optimal design of a motor is examined by applying it to the design of the verification model of the IPM motor established by the technical committee of IEE of Japan. Factors affecting torque ripple and driving torque of the obtained optimal motor core are also discussed. [ABSTRACT FROM PUBLISHER]

We developed a parallel computing method of the magnetic field for rotating machines by using the 3-D finite element method (FEM) with edge elements. In this paper, we describe the outline of the developed method and an optimization of the method for the Earth simulator, which is a vector-type parallel supercomputer in Japan. Moreover, the performance of the proposed method running on the Earth simulator is quantitatively clarified. [ABSTRACT FROM AUTHOR]

In order to examine estimation methods of iron losses of rotating machines, a verification model of the surface permanent magnet (SPM) motor is manufactured and measured by the investigation committee of the IEE of Japan. The effect of stress due to the insertion to aluminum case on magnetic characteristics can also be investigated by using the model. In this paper, features of the benchmark model are discussed, and some results of calculation and measurement are shown. Various kinds of methods for estimating iron losses due to distorted elliptical rotating flux are discussed. It is illustrated that the difference between results estimated using those methods and measured iron loss is within 10%. [ABSTRACT FROM AUTHOR]

The Fifteenth Biennial IEEE Conference on Electromagnetic Field Computation (CEFC 2012) was held in Oita, Japan, on November 11-14, 2012. The statistics for CEFC 2012 are as follows: the registered attendance was 347 participants and 28 countries were represented at the Conference. There was an appreciable number of participants attending from Korea, China, France and Brazil, with a broad spectrum of people from all over the world. Of the 617 abstracts submitted, 496 were presented. There were three invited lectures and one keynote speech, with 133 oral presentations and the remainder of digests (363) presented as posters.
