Product Description:

The MHD071B-061-NP3-UN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It supplies regulated rotary motion for automated axes in packaging lines, material-handling gantries, and general machinery, where precise speed and position control are essential. This type of motor is suited to applications that require repeatable positioning, smooth acceleration, and stable low-speed operation across changing duty cycles. By combining a compact 071 frame with digital feedback, the unit works with compatible drive controllers to maintain commanded trajectories under variable mechanical loads.

At standstill, the motor delivers a continuous torque of 8.0 Nm, meaning it can hold that load continuously without exceeding its thermal limits. Heat is removed through liquid cooling, and coolant passages in the housing carry thermal energy away from the stator so full output is available even inside sealed cabinets. This cooling method supports continuous operation where ambient airflow is limited or where cabinet space is tightly enclosed. A 115 mm square flange follows common mounting patterns for straightforward installation. The power connector is turnable through a range of 270°, allowing the cable outlet to be directed toward the required conduit path. Position information is supplied by a digital servo feedback (HSF) encoder, which sends high-resolution data to the controller for tight velocity and torque regulation.

The centering diameter is 95 mm, providing an accurate pilot that helps prevent shaft misalignment during assembly. An internal brake supplies 10.0 Nm of holding torque to secure vertical axes when the drive is disabled. Torque is transmitted through a keyed shaft, and a shaft seal helps prevent fluid ingress during washdown or coolant exposure. This shaft arrangement supports positive torque transfer to couplings, pulleys, or gear inputs while protecting the front bearing area. Winding code 061 identifies the electrical characteristics used with the B-length stator, and the combined power and feedback connectors simplify wiring.
