Product Description:

The MKD071B-061-KG3-KN is a servo motor from the MKD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It serves as the rotating actuator in machining centers, packaging lines, and other automated equipment that rely on precise torque production and rapid speed changes. When paired with a compatible drive controller, the unit supports coordinated multi-axis motion while maintaining the efficiency typical of a permanent-magnet synchronous design.

Mechanical mounting begins with a centering diameter of 95 mm that aligns the housing to the machine frame and a square flange measuring 115 mm that accepts standard ISO fasteners. The MKD size 071 stator package and B-length stack support a continuous standstill torque of 8.0 Nm without exceeding permissible winding temperature. Power and feedback conductors exit toward the rear because the electrical interfaces are oriented on Side B, and they terminate inside a sealed connection box that simplifies cable routing. A resolver feedback unit is integrated, and the analog rotor position signal it provides lets the drive commutate the motor sinusoidally at all speeds. A shaft seal is fitted at the output end to protect internal bearings from coolant splash and dust ingress.

The motor has a holding brake that engages automatically when the drive disables current to secure the load during power-off conditions. Motion data is retained by absolute feedback that resolves positions over >4096 revs, which eliminates homing moves after startup. The rotor couples to machinery through a plain shaft that minimizes runout and accepts clamp-style couplings supplied by the machine builder. Winding code 061 identifies the wire gauge and turns ratio used for the required voltage class, giving the axis predictable dynamic response without auxiliary sensors.
