Synapticon SOMANET Circulo 7 and 9 Servo Drives

SOMANET Circulo packages a servo drive around a hollow center for integration into robot joints and smart actuators. Circulo 7 and Circulo 9 have different electrical capacity, central clearance and encoder resolution. Integrated encoder rings, a brake and extended Safe Motion functionality depend on the selected construction. The product is drive and sensing hardware for an engineered axis, not a complete robot joint with a motor and gearbox already included.

Applications and Industries
Robot-joint and smart-actuator integration requiring a hollow local-drive package
Industrial automation
Review Summary
Consider Circulo when the joint architecture benefits from local drive electronics and a central cable route. Select the 7 or 9 from the actual continuous load, transient duty and mechanical envelope. In particular, the family’s 60 A RMS headline belongs to Circulo 9 peak phase current; it is neither Circulo 7 capability nor Circulo 9 continuous current.
