Planetary Gearboxes

COSMOS Series

Planetary gearboxes feature a robust design and are used in applications requiring high performance and small size. The gear train can be metal, plastic, or, on request, in a mixed configuration. The gearboxes are lubricated according to application needs based on temperature and functionality. Servotecnica’s COSMOS gearboxes best suit ATOM Series Brushed and Brushless Coreless Micromotors combinations.
Customizations are available upon request.
