Small Motors

Adamant Namiki Precision Jewel has consistently contributed to society as a pioneer of small motors in Japan since developing the world's smallest φ10 mm DC coreless motor of its time in 1973.

The φ10 mm motor, which was unprecedented at the time, was the result of research into rare-earth magnet manufacturing methods and precious metal brushes, along with the introduction of a coreless winding patent from Germany.
After that, we continued to pursue technological innovations, and successfully developed the φ1.5mm geared motor in 2004 (which was awarded the Prime Minister’s Prize in 2006) and the current world’s smallest φ0.6mm brushless motor in 2014. These products truly bring together the precision processing techniques that we have been cultivating through jewel processing since our founding.

In addition to our responsive and quiet coreless and brushless motors, gearheads, encoders, and control boards, we also offer motion units that further combine mechanisms to meet the various needs of our customers.
Adamant Namiki’s product lineup of small (under φ30mm) motors and peripheral devices helps meet demands for smaller, thinner devices, high power output, and energy efficiency.

As society has become increasingly complex in recent years, the challenges and needs of customers are also becoming more diverse. Adamant Namiki Precision Jewel offers solutions not only for small motors, but also for integrated units, optical devices, and other components.
