Therefore, the improvement of motor efficiency is very effective in reducing energy-related carbon dioxide emissions, and is a very important research topic from the perspective of countermeasures against global warming and the depletion of energy resources. Accordingly, we are conducting research on &#8220;high performance motors&#8221; and &#8220;bearingless motors and magnetic bearings utilizing magnetic levitation&#8221; with the aim of &#8220;reducing the environmental burden caused by motors.<\/p>\n<ul>\n<li><a href=\"https:\/\/www.cc.okayama-u.ac.jp\/~eng_mse\/index.html\">Link to group homepage<\/a><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<table class=\"el_table_fix\" style=\"width: 100%\">\n<tbody>\n<tr>\n<th style=\"width: 20%\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium\" src=\"https:\/\/www.elst.okayama-u.ac.jp\/up_load_files\/areas\/areas03_elect\/TSUNATA Ren.JPG\" width=\"320\" height=\"408\"><\/th>\n<td style=\"width: 80%\">\n<ul>\n<li style=\"list-style-type: none;font-size: 12px;margin-left: -20px\"><span style=\"font-size: 12pt\">Assoc.
