Some features of the Namiki DC motor include its super small size (a diameter of 2mm & 4mm), low inertia, and quick response. Since the development of the smallest coreless motor in 1973, Namiki has successfully commercialized the DC micro 2mm diameter brushless motor into the market. Since then, it has been widely used in various industries such as the medical equipment, analytical, physics and chemical fields that require small and precision motion control functions.
