MHD071B-061-PG3-UN
MHD Synchronous Motors
MHD071B-061-PG3-UN, Bosch Rexroth Indramat, MHD Synchronous Motors. The MHD071B-061-PG3-UN magnet motor delivers high-precision motion with a nominal speed of 4500 min⁻¹ and is equipped with a multifunction Digital servo feedback w/ integrated encoder. It features a Winding Code of 061 and a robust plain shaft design to handle heavy loads without bending. Safety is assured by an electric-resistant housing and integrated sealing rings preventing ingress of water and particles.
The motor’s Holding Brake provides a 10.0 Nm Holding Brake Torque, securing tools in vertical positions and preventing unintended motion. Continuous output at standstill reaches 8.0 Nm Continuous Torque at Standstill, while the Type of Position Detection is Absolute (>4096 revolutions) for multi-turn accuracy. A Housing Cooling Type of liquid cooling maintains optimal temperature control across 0 … 45 °C. The unit uses a Centering diameter of 95 mm and a Flange size of 115 mm, housed in a Motor Size 071 envelope. Power and feedback connectors are turnable within a range of 270° Power Connection Direction, simplifying installation.
Engineered for seamless integration, the MHD071B-061-PG3-UN pairs with standard Rexroth drives and controllers for synchronized multi-axis operation. Its liquid-cooled housing and reinforced shaft seal enhance reliability in demanding CNC machining, robotics, and automated tool-changing applications. With its compact footprint and modular connector orientation, this servo motor offers exceptional uptime, precision positioning, and ease of maintenance in industrial automation systems.

Frequently Asked Questions
How does the 10 Nm holding brake improve vertical axis safety?
The holding brake prevents unintentional motion during power loss or shutdown, especially for vertically mounted tools. It ensures load retention without needing external mechanical locks.
Why is multi-turn absolute feedback important in automated systems?
Multi-turn encoders retain position data even after power loss, eliminating the need for re-homing. This is critical in systems requiring uninterrupted positioning, like in robotics or packaging lines.
What role does the 270° rotatable power connector play in installation?
It allows flexible cable routing, making it easier to fit the motor into tight or complex machine layouts. This reduces cable strain and simplifies retrofit applications.
Does the MHD071B-061-PG3-UN support high-inertia load applications?
Yes, its plain shaft and torque characteristics support moderate to high inertia loads without compromising positional stability. This suits milling heads or indexing tables.
How does this motor behave at standstill under continuous torque load?
It can deliver continuous 8.0 Nm torque at standstill, suitable for static holding under full load. This is essential in tasks like press-fit operations or clamping.
