Takemoto-Kiyota Lab
Machine-translated · View original
A lab that builds prototype motors that use no rare-earth magnets, as well as motors whose rotors levitate as they spin.
AboutAbout the lab
Magnet-free motors and levitated spinning motors
Takemoto-Kiyota Lab studies new motors that contribute to energy saving and the reduction of greenhouse gases.
One line of research is the switched reluctance motor, which achieves high performance without rare-earth magnets and is intended for use in electric and hybrid vehicles.
The other is the magnetically levitated bearingless motor, which uses no bearings and instead levitates and supports the rotating shaft with electromagnetic force.
Combining electrical, mechanical, information, and electronic engineering, the lab places importance on actually designing, prototyping, and testing motors.
Key terms
- Bearing
- A component that supports a rotating shaft so that it turns smoothly
- Switched reluctance motor
- A motor made only of an iron core and windings. Because it uses no permanent magnets, it is inexpensive and robust
- Rare earth
- A group of elements used as materials for strong magnets. Their supply and prices tend to be unstable

The lab studies new motors that contribute to energy saving and the reduction of greenhouse gases. It covers everything from motor analysis and design to prototyping, experiments, and evaluation, and places importance on verifying results on actual machines.
*Illustrative imageBearingless motors that levitate as they spin
These motors support the rotating shaft without contact, using electromagnetic force instead of mechanical bearings. They have no friction or wear, and the lab aims to apply them to cooling fans, wind power generators, and similar equipment.
*Illustrative imageMagnet-free motors (SRM)
This research concerns switched reluctance motors, which are inexpensive and robust because they use no permanent magnets. The lab demonstrated performance with a full-scale prototype and also proposed a current excitation method that reduces vibration and noise.
