2 Pole High-speed Coreless Brushless Micromotors

ATOM HS Series

Typically employed in the medical field for surgical tools, these motors merge the SVTN A Series characteristics into an optimized project for high-speed functions.
Thanks to the precise balancing of the rotor and the use of special bearings, maximum stability, and low noise are guaranteed.
