Product Description:

The MHD071B-035-NG0-UN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. As a rotary actuator, it delivers precise electromechanical motion for automated equipment and works with drive controllers that regulate position, speed, and torque. In automated machinery, it can serve feed axes, rotary tables, or handling modules that require smooth response to changing command values. The motor uses size 071 with length code B, and it is supplied without a holding brake, so vertical loads require external retention when power is removed.

Its centering pilot measures 95 mm, allowing accurate alignment against matching machine frames, while the square flange spans 115 mm to fit standard IEC mounting layouts. This combination supports repeatable mounting geometry when the motor is attached to machine plates or gearbox interfaces. At the stator, a continuous standstill torque of 8.0 Nm is available, which supports stable holding force at zero speed while the drive remains energized. Rotor position is monitored by digital servo feedback (HSF), and the encoder signal allows the controller to correct position and speed errors continuously. Thermal energy is removed by liquid cooling, so coolant channels in the housing help maintain winding temperature during demanding load cycles in compact installations.

The output side uses a plain shaft, so torque is transferred through clamp hubs or shrink discs instead of keys or splines. A shaft seal is present to limit lubricant escape and help block dust ingress along the journal and bearing area. Power and feedback connectors share a common housing, and the assembly is turnable within a 270° range, allowing cable exits to be directed toward the nearest routing channel. The shared connector housing reduces the number of separate connection points on the motor body. Position feedback is internally referenced, so the motor provides relative displacement information and requires homing after power-up. The stator follows winding code 035, matching the motor to drive modules that supply the appropriate current and voltage for this torque class.
