Abstract
As reported in this article in 2022, a synchronous reluctance motor (SynRM) has many advantages over conventional motors [1]. Conventional high-efficiency motors generally use rare earth permanent magnets. In comparison, a SynRM does not use permanent magnets. Rare earth metals, the raw materials for permanent magnets, emit lots of CO

during their mining processes and are thus inconsistent with creating a green society. Furthermore, such materials are not abundant and are only produced in a few countries. Therefore, a SynRM, which does not use rare earth permanent magnets, is superior from the perspective of preventing global warming and avoiding geopolitical risks.
期刊介绍：
The EI Magazine publishes articles written by authors from industry, research institutes and academia. The articles are more practical in content than the papers published in the Transactions. Usually three articles are published in each issue. The articles deal with dielectric materials, processes and new developments applied to industry products. Also the EI Magazine is used to promote upcoming conferences and solicits papers for the conferences. In addition, reports on past conferences are given in many issues. Book reviews and news items are included. An editorial is written by both the EIC and the President of DEIS in alternate issues. Advertising of insulation products appears in many issues.
