Industrial 3HAB8101-8 Servo Drive Rectifier Unit

ABB 3HAB8101-8 is an Inmotion servo drive rectifier unit that serves as the power conversion module in ABB's Inmotion industrial robot servo drive systems. This rectifier unit accepts AC input and provides the DC bus power required by the servo drive to drive multi‑axis robots, enabling precise speed and torque control in automation cells. The base model is specified at 14A, with distributor variants such as 3HAB8101-8/15A and 3HAB8101-8/17C used to suit different installation requirements. In many ABB Inmotion configurations, this rectifier unit integrates with the DSQC346G family of drive electronics to support high‑speed servo operation and reliable performance in demanding environments. Common applications include robotic cells and automated manufacturing lines that deploy ABB Inmotion servo drives for precise motion control of industrial robots. As part of the Inmotion line, the 3HAB8101-8 family is intended to be paired with the corresponding servo drive modules and control electronics to implement robust automation solutions, with multiple current/rating variants offered by distributors to fit space and load constraints.
