NAMIKI have developed a variety of products with smallest in size for DC motor solutions since 1939, and been leading the technologies in the field.

About this Solution:

Our standard product line includes instrument quality Coreless DC and Brushless motors with available gearheads, encoders and driver electronics. Namiki precision technology produces the worlds’ smallest Brushless DC motor / gearhead.

Technology Calendar (1939 ~ Present)


DC Motors:

Motor Requirement Trend:


Coreless Motors:


Namiki DC coreless motors are available in sizes from 7 to 18 mm diameter, featuring high efficiency and low power consumption motors. The low inertia rotor coil provides quick response with no cogging and features a skewed winding for smooth torque generation. The high performance rare earth magnets for these motors are produced by Namiki using our own precision manufacturing technology. Optional gearheads in planetary or spur configurations, as well as, encoder position feedback are available to meet most application requirements. These instrument grade motors have been widely used in many various applications, such as: auto focus cameras, measuring instruments, medical devices, and personal electronics.



Brushless Motors:


Our brushless motor lineup includes models from 4mm diameter up to 22mm diameter sizes. All have low inertia rotors for quick response, and hi energy rare earth magnets for optimum performance. The slotless, brushless motors achieve more efficient operation through low damping losses.

Planetary and spur gearheads, as well as high resolution encoders are available to meet critical application requirements. A miniature size driver board is featured for sensor-less commutation models. Namiki brushless motors provide high reliability and long life for high value applications such as medical equipment, analytical instruments, and robotics.


  • Driver Specification / Applicable Motor:





Planetary and spur gearheads with the wide range of gear ratios are available for all coreless and brushless motor models. Namiki original miniature size gearheads continue to provide excellent value for applications which require low noise operation and long life.
