Electric servo-actuator ACTILINK-JD Circulo 12

rotaryservo-motorplanetary gear

Overview
ACTILINK-JD SERIES - High-dynamic robotic joint actuator designed for applications requiring high dynamics and efficiency such as humanoid and polyped robots. Light and compact low-reduction actuator combining a precise single-stage planetary gearbox and a high torque-density motor. Engineered for compact integration with high power transmission, low backlash and high power-to-weight ratio. Integrated with the Synapticon SOMANET Circulo servo drive family and supporting EtherCAT communication.
