Product Description:
Bosch Rexroth Indramat manufactures the MKD071B-061-KG1-KN synchronous servo motor within the MKD Synchronous Motors series. As a servo motor, it converts drive command currents into precisely metered shaft rotation for positioning and velocity loops in industrial automation. The integrated feedback device allows the drive controller to close the loop quickly, making the unit suitable for pick-and-place axes, packaging spindles, and general motion modules that demand repeatable step accuracy. Its construction pairs electromagnetic windings with permanent magnets to support dynamic response while keeping the housing compact.
Electromechanical output begins with a continuous standstill torque of 8.0 Nm, giving the drive enough static force to hold or move loads without overheating during idle clamping phases. Mounting is guided by a 115 mm square flange that matches standardized gearbox and machine frames, while the 95 mm centering diameter keeps the motor concentric to the driven member and limits radial runout. Internally, winding code 061 identifies the copper fill, resistance, and inductance used when pairing the motor with MKD-compatible inverters across nominal voltage classes. Motion feedback is supplied by resolver feedback, which integrates rotor-position sensing hardware inside the stator and enables analog angle reporting even under electrical noise that would hamper digital sensors.
Cabling enters on Side B through a sealed connection box, separating power conductors from signal lines and simplifying routing in cramped cabinets. A factory-mounted brake rated at 5 Nm clamps the rotor whenever supply voltage is removed, which helps vertical axes resist back-driving. The output end uses a plain shaft, so torque is transmitted through friction-fit couplings rather than keyed engagement, reducing backlash. Position data is retained by an absolute (>4096 revs) feedback system, allowing the controller to resume coordinated motion after power cycles without homing. An internal shaft seal helps prevent lubricant migration, and the motor length B in size 071 keeps the overall mass moderate for gantry-mounted applications.
