In recent years, a thermal analysis of electric motors becomes more important following an increase of power density. Especially, it is very important for design and analysis of permanent magnet (PM) motors since characteristics of the permanent magnet are deteriorated by heat due to losses. To realize a quantitative thermal design and prevent from overheat, it is essential to establish an electromagnetic and thermal coupled analysis method for the PM motors. This paper presents a method for
