Product Description:

The MHD071B-061-NP2-UN is a servo motor built by Bosch Rexroth Indramat as a member of the MHD Synchronous Motors series. The size code 071 and the B-length housing give it a mid-range mechanical envelope that fits compact automation stations while still supplying the torque needed for closed-loop motion. Within an integrated drive system, this motor receives current from a digital inverter and returns high-speed feedback, providing precise position and velocity control for tooling heads, gantry axes, and conveyor modules. Its internal winding designation 061 matches the drive parameters used for correct current and voltage limits.

The continuous stall capability of 8.0 Nm is the load that the rotor can hold indefinitely without overheating, making the unit suitable for indexing tables or tension-controlled winders. Mounting is through a 115 mm square flange that aligns with standard IEC motor adapters, simplifying installation on existing machinery. Heat generated by copper losses is removed through liquid cooling, so the motor can maintain rated torque even in sealed enclosures with minimal airflow. Position and speed are exchanged with the controller via digital servo feedback (HSF), enabling high-resolution electrical commutation and rapid dynamic correction.

The centering pilot measures 95 mm, ensuring concentric alignment between the flange and gearbox bores. An internal holding brake rated at 6.5 Nm locks the shaft when power is removed, preventing drift on vertical or suspended loads. The main power plug can be swiveled through 270°, and the combined power and feedback connectors allow flexible cable routing inside tight panels. Output torque is transferred through a keyed shaft, and a shaft seal keeps lubricant and contaminants separated. The motor reports relative position data for closed-loop motion control.
