Product Description:
The MHD071B-061-PP1-UN is an AC servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is intended for closed-loop motion axes in assembly systems, packaging machines, and other automation tasks where precise position and speed control are required. The construction follows IEC mounting dimensions to simplify interchange with legacy motors, and it interfaces directly with Indramat drive controllers to convert commanded currents into accurate shaft rotation synchronized with external processes. This arrangement suits indexing tables, feed axes, and synchronized transfer mechanisms that depend on repeatable motion under changing loads.
For mechanical integration, the motor mounts to a machine frame by means of a flange that measures 115 mm across and is centered by a 95 mm pilot diameter, ensuring radial alignment with the driven equipment. That flange-and-pilot arrangement helps maintain concentric alignment between the motor and the connected load, which supports smoother torque transfer through couplings and gearbox inputs. Mechanical power leaves the unit through a standard keyed output shaft. The winding labeled 061 delivers 8.0 Nm of continuous standstill torque to support static loads without overheating. Position feedback is supplied by a digital servo feedback unit that combines commutation signals and multiturn data, and its resolution provides absolute feedback for more than 4096 revolutions so the controller can recover position after power loss without a homing routine.
A permanent-magnet holding brake rated at 5.0 Nm secures the shaft during power-off events. Heat is removed by liquid cooling passages in the housing, helping the motor maintain rated torque in confined enclosures where ambient heat can build up around the frame. The power plug is rotatable within a 270° range, which makes cable routing easier when space around the motor is limited or the connector must face a specific direction. Electrical connections use power and feedback connectors with a sealing ring, and the keyed shaft includes a shaft seal to limit ingress during operation.
