Product Description:

The MHD071B-061-PP2-UN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for closed-loop axis control in industrial automation, the motor converts drive current into regulated rotary motion for positioning and speed tasks on packaging lines, material handlers, and other CNC-based equipment. Its synchronous design supports repeatable acceleration, controlled stopping, and stable speed regulation in automated axes.

The motor’s physical envelope follows the 071 frame code and length designation B, giving a compact body that aligns to machinery through a centering diameter of 95 mm and a square flange of 115 mm. A keyed shaft with a fitted shaft seal transmits torque while blocking lubricant escape. At standstill, the rotor can deliver 8.0 Nm continuously, and the integrated holding brake secures loads with 6.5 Nm of static torque during power-off. Thermal energy is removed by liquid cooling, and the enclosure is rated IP65 for resistance to dust and low-pressure water jets. Winding code 061 identifies the coil geometry, and the stator windings use power and feedback connectors that can rotate through 270° for cable relief. Digital servo feedback built into the housing streams absolute position data to the drive for synchronized multi-axis motion.

Absolute position over more than 4096 revolutions is detected optically, allowing the controller to hold and return to any angle with a system precision of ± 0.5 angular minutes. Electrical insulation meets Class F limits, and the permitted ambient temperature during service is 0 to 40 °C. When stored or shipped, the assembly may remain anywhere from -20 to +80 °C without damage, and it can be mounted up to 1000 m above mean sea level without derating. A keyed housing profile aligns the power connector, which shares the shell with the feedback plug.
