Product Description:

The MHD071B-061 is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It is intended for position and velocity control in automated machining cells, pick-and-place modules, and packaging axes where drive current is converted into tightly regulated rotary motion. Feedback from the motor allows digital controllers to correct speed and position continuously during operation. This makes the unit suitable for synchronized acceleration, deceleration, and short settling times between commanded moves. It can serve axes that need accurate coordination with conveyors, tooling heads, or rotary transfer mechanisms.

The mounting pilot has a 95 mm centering diameter that provides a consistent reference for shaft alignment with gearboxes or belt pulleys. A square flange of 115 mm carries mounting loads into the housing, and its face-mount layout supports rigid attachment to machine plates. Continuous stall torque reaches 8.0 Nm, allowing the axis to hold position at low speed or standstill against static process forces. The frame code 071 indicates the motor size, while the B length uses a longer active section to increase thermal mass and torque density. Winding code 061 matches the electrical characteristics expected by compatible power modules. The pilot and flange arrangement also help maintain concentric mounting, which reduces coupling stress during repeated reversals.

In operation, the motor supports dwell periods, indexing moves, and repeated speed changes without sacrificing position stability. Its housing geometry suits multi-axis assemblies where several servo-driven stations need a consistent mechanical footprint and predictable alignment. The selected frame length and winding variant balance response and heat dissipation during moderate duty cycles. In transfer systems, feeders, and rotary tables, this behavior supports repeatable start-stop motion and smooth recovery after rapid speed changes. When the drive applies current under normal thermal limits, the motor can resist load disturbances at standstill and maintain controlled shaft position. This also helps maintain consistent part handling when the mechanical load changes from cycle to cycle.
