due to the secondary conductor loss of the rotor, which is a challenge for making compact, high-efficiency motors. However, the developed motor has been made smaller by increasing the maximum rotation speed to 32,000 rpm, and to address the increased iron loss that occurs at higher rotation speeds, amorphous core material has been used instead of electromagnetic steel sheet, improving efficiency by 1.4%.   The thickness of amorphous materials is...
