About Rotary Actuator

eRob rotary actuator, also called eRob servomotor or eRob servo motor, is an all-in-one robotic joint.

eRob servomotor unites in a single housing all the main elements: dual absolute encoders, a controller, a harmonic gear and a servo motor. Since the controller is integrated into the robotic actuator, the eRob series is a DC servomotor with a brushless AC core.

ZeroErr provides a 1-YEAR WARRANTY. Our online support team is eager to help you whenever needed. Detailed video instructions and technical documentation are provided. Average servomotor lead-time 2-4 weeks.

ZeroErr has the first international ISO9001 certificate among domestic counterparts. What's more, we have CE certificate and RoHS report. Our eRob rotary actuators satisfy the requirements of the Electromagnetic Compatibility Directive 2014/30/EU.
