Thank very much for attending the 23rd International Conference on Electrical Machines and Systems (ICEMS2020). ICEMS started in China since 1987 and has been held 4 times in Japan in the past (2006 Nagasaki, 2009 Tokyo, 2012 Sapporo, and 2016 Chiba). This is the fifth time that the Institute of Electrical Engineers in Japan (IEEJ) organized ICEMS. This conference is co-organized by the KIEE Electrical Machinery and Energy Conversion Systems Society (KIEE-EMECS) and the China Electrotechnical Society (CES), and is also technically co-sponsored by the IEEE Industry Applications Society (IEEE-IAS).

In May 2020, according the pandemic of COVID-19, we discussed how to hold ICEMS2020 surely and safely, with the International Steering Committee of ICEMS. Finally, we decided to organize ICEMS2020 as an on-line conference. We never forget the kind suggestions and opinions at that time.

Now, ICEMS2020 is about to begin. We strongly believe, even the conference style has changed, ICEMS2020 will provide a big opportunity for researchers and professionals from all over the world, to present the latest researches and developments and to exchange useful information and experiences in the fields of electrical machines and systems, such as motor drive systems, turbine generators, linear machines, transformers, electric vehicles, renewable energy, power converters, etc.

I would like to extend a hearty welcome to all of you for participating the 23rd International Conference on Electrical Machines and Systems (ICEMS 2020 – Hamamatsu).

An ICEMS conference is held every year in China, Korea, Japan and the fourth country in turn. This is the 23rd ICEMS conference and the 5th ICEMS organized by the Institute of Electrical Engineers of Japan, the Industry Applications Society (IEEJ-IAS). The first ICEMS organized by the IEEJ-IAS was in Nagasaki in 2006, the second in Tokyo in 2009, the third in Sapporo in 2012, and the fourth in Makuhari, Chiba in 2016. Since then about four years have passed. The original plan of ICEMS 2020 was to hold the conference in Hamamatsu, Japan. But as you know well, there are still concerns about the spread of COVID-19 infection, and, therefore, we have decided to hold ICEMS 2020 as a virtual conference.

The ICEMS has contributed to the promotion of academic and technological exchange in the fields of electrical machines and systems, and also to the progress of the fields. In the conference we have participants in a wide age range from young students to senior professors and engineers. Especially we have many students of graduate schools. It would be very important for us to stimulate interest of the students and young professionals through the program of the conference and to develop engineers and leaders of the next generation. In the ICEMS conferences the international exchange, communication, and friendship are also very important. I expect that the ICEMS 2020 will contribute to enhance the international cooperation among the academic societies and to develop our friendship furthermore.

I do hope that the conference will be very fruitful for all of you and that you will enjoy the conference.

Welcome to the 23rd International Conference on Electrical Machines and Systems (ICEMS2020). We initially planed this conference to hold at Hamamatsu, which is one of the heart cities of automotive industry in Japan. As everyone knows, however, COVID-19 unfortunately prevented us to achieve our goal. Hamamatsu was nominated as a conference site because our technical trend is accelerating towards electrification of vehicles, which matches ICEMS technical scope very well. In addition, this city has great reputation in Japanese automotive industrial history because Sakichi TOYODA (TOYOTA), Soichiro HONDA, Michio SUZUKI, and Torakusu YAMAHA, all legendary engineers were born or working in Hamamatsu area.

Even though the conference management has been switched to “web remote style,” I believe that the sprit of “YARAMAIKA!” (LET’S TRY IT! in a Hamamatsu dialect) is still alive in the heart of all the attendees of the conference. I really hope this conference can provide every participant with wonderful exchanges of the latest technologies and academic knowledge.

Enjoy the conference and YARAMAIKA! in electric machines and systems.

Welcome to the ICEMS2020 Web Remote Conference! I am very pleased that ICEMS2020 will be held with more than 400 conference papers. On behalf of the Technical Program Committee (TPC), I would like to express our sincere gratitude to all who have been involved in the ICEMS2020. The TPC has conducted strict peer review and plagiarism check for all conference papers. We are confident that high quality papers have been submitted, thanks to the efforts and cooperation of all the authors. All papers presented at the ICEMS2020 will be posted on the IEEE Xplore Digital Library. Every author who has presented a paper at ICEMS 2020 can submit a revised version of his/her manuscript for review for publication in one of the following journals: IEEJ Journal of Industry Applications (the same version as the conference paper will be also accepted), IEEE Transactions on Industry Applications. Details will be announced at the opening ceremony. Enjoy the conference!

With a growing field of electrical machines and systems area, it is supposed to be more exciting and productive to have the 23rd ICEMS meeting in Japan this year. However, regrettably we cannot gather and share our achievement due to the outbreak of COVID-19 that is the event with serious impact we have not experienced ever.

Now everyone knows that world after COVID-19 must be totally different from that before COVID-19. Academic meetings are not an exception and rather a representative example of changing norm. Even though we cannot meet each other in the same place and time, fortunately we can exchange our experience and knowledge by virtue of the current communication technology. Despite many troubles caused by COVID-19, communication and friendship in our society should be continued.

Since the first conference was commenced, this meeting has become a fundamental ground to exchange quality results and ideas provided by the researchers and scientists within universities, industries and institutes under the close cooperation and collaboration among the China Electrotechnical Society (CES), the Korean Institute of Electrical Engineers (KIEE), the IEEE-Industry Applications Society (IEEE-IAS), and the IEEJ Industry Applications Society (IEEJ-IAS). Hence, I strongly believe that the ICEMS 2020 will be also a great opportunity for everyone attending here to enrich their professional network.

Finally, we hope this virtual meeting becomes the meaningful beginning of the future that is much better than before. On behalf of KIEE Electrical Machinery and Energy Conversion Systems Society, co-organization of ICEMS, we thank you again for your commitment to ICEMS and its community, particularly during these difficult times. We hope this virtual meeting is enjoyable and informative to everyone and this field continues to progress.

It is an honor of China Electrotechnical Society (CES) to cooperate with IEEJ Industry Applications Society (IEEJ-IAS), the Korean Institute of Electrical Engineers Electrical Machinery and Energy Conversion Systems Society (KIEE-EMECS), and the IEEE-Industry Applications Society (IEEE-IAS).
