You will learn the latest technology about the new energy-saving electromagnetic force application system that has been attracting attention recently. As we move towards a low-carbon society, there is a growing focus on making devices more energy efficient, and you will learn about the technologies and devices that are being used to achieve this.
The specific learning objectives are as follows
・Understand how to obtain mechanical power from magnetic field energy.
・Derive the mathematical model of an IPMSM motor.
・Understand how to apply vector control.
・Understand the types of reluctance motors and their drive methods.
・Understand the technology for improving efficiency using variable field magnet motors.
・Derive the mathematical model of various magnetic levitation systems.

It is desirable to have completed the following subjects.
・Vector Analysis in Electromagnetism
・Theory on the Dynamics of Electric Circuits
・Electrical Power Circuits
・Electric Machinery
・Linear System
・Control System I, II
