MOTOR SYSTEMS ENGINEERING
From electricity to motion.
From motion to the future.
Takemoto–Kiyota Motor Lab explores smarter, more powerful ways to use energy through research on next-generation motors, magnetic levitation, and drive and control technologies.

Research
We do not stop at simulation. We design, build, run, and validate.
Our work connects electrical engineering, mechanics, electronics, and information science—and values proof on real hardware.
01
High-performance motors
We pursue efficient, compact, high-output motor systems, including rare-earth-free and application-specific designs.
02
Magnetic levitation
Bearingless motors and magnetic bearings enable contact-free rotation for high-speed and demanding environments.
03
Magnetic materials, vibration, and noise
We characterize magnetic materials and evaluate vibration and noise to improve motor performance and quietness.
04
Drive and control
Sensing and digital control bring new motor structures to life and reveal their performance on real hardware.
