Product Description:

The MHD071B-035-PG0-UN is a servo motor produced by Bosch Rexroth Indramat and supplied within the MHD Synchronous Motors series. As an electromechanical actuator, it converts regulated three-phase current from a compatible drive into controlled rotary motion for positioning, indexing, and continuous-duty tasks in automated lines. Integrated feedback electronics, internal coolant passages, and a sealed stator chamber allow this motor to operate near machining, packaging, or assembly stations where precision and sustained torque output are required. It is suited for axes that need repeatable motion and steady performance over long operating periods.

The motor has a centering shoulder diameter of 95 mm, which helps keep the housing concentric with the mounting surface. Its square mounting flange measures 115 mm, providing adequate bolt spacing for medium-frame gearboxes. During continuous stall, it can supply 8.0 Nm, allowing axis controllers to hold loads without thermal derating. Heat generated by copper losses is removed through liquid cooling, which permits higher RMS currents than comparable air-cooled units. This model is delivered without a holding brake, eliminating the added backlash and inertia associated with internal brake disks. When static holding is required, that function must be handled outside the motor.

Rotor position information is generated by digital servo feedback with an integrated absolute track, providing multi-turn measurement for more than 4096 revolutions to the drive. This allows the control system to retain position information across many shaft turns instead of relying only on single-turn data. The connector housing can be turned through 270°, so power cabling can be routed in a preferred direction, and both power and encoder signals exit through combined connectors. The output side uses a plain shaft, so couplings or pulleys mount directly without key machining, and an installed shaft seal protects the bearings from coolant ingress. Motor size 071, length code B, and winding code 035 are used by the controller to apply the correct commutation tables and thermal model.
