In japan, 60% of total power consumption is concumed by electical motors. Accordingly high efficiency is highly required
for the motors. Currently various apparatuses motoried, for example electric vehicles.
This course will explain a design method for highly efficience and high performance parmanent magnet motors (PM motors) in detail.
