Product Description:

The MKD071B-061-KG1-KS is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It supplies rotational power to industrial axes that require synchronized motion with closed-loop feedback. Mounted on machinery through its square flange, it connects to the drive controller through a side-mounted connection box and sends position data to the control system so automated processes can maintain commanded speed and angle. Its closed-loop operation helps the drive correct load-related speed variation during normal machine use. This motor is suited for handling, packaging, and transfer tasks where repeated starts, stops, and speed changes must remain consistent over long operating periods.

The mechanical interface uses a centering diameter of 95 mm, and the square flange dimension of 115 mm provides the bolt pattern for rigid attachment to a machine plate or gearbox. At standstill, the rotor can deliver 8.0 Nm continuously, which allows the axis to maintain torque at zero speed without thermal overload during normal duty. Position feedback is provided by an integrated resolver feedback unit that sends shaft position data to the drive, and a spring-applied brake produces 5 Nm of static torque to hold the load when power is removed. Electrical insulation meets class F limits, and the housing has an IP65 rating that helps protect internal parts from dust and low-pressure water jets commonly found around industrial equipment.

The closed-loop system can maintain motion within ±8 angular minutes, which supports repeatable positioning in indexing, feed, and transfer applications. Operation is permitted at ambient temperatures from 0–40 °C, so the motor can run in typical industrial conditions without extra cooling equipment. Winding code 061 identifies the electrical winding used in this frame size, allowing the matching controller to apply suitable current values for torque production while staying within the motor's thermal limits. The motor is suitable for axes that require accurate motion and steady operation during frequent start-stop cycles.
