MHD071A-061-NG0-UN
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD071A-061-NG0-UN is a high-performance component in the MHD Synchronous Motors series, designed for precision motion control in demanding industrial environments. As a specialized servo motor, it delivers a continuous torque at standstill of 3.5 Nm and employs a robust liquid cooling housing system to manage thermal loads during extended operation. Equipped with a digital servo feedback (HSF) encoder and relative position detection, this motor ensures accurate positioning and dynamic response for automated systems requiring tight control and repeatability.
This servo motor features a compact motor size of 071 with a motor length A profile, built around a 95 mm centering diameter and a 115 mm flange size for versatile mounting options. The plain shaft design includes a shaft seal to protect internal components from contamination, while the 061 winding code optimizes the motor’s electromagnetic characteristics for efficient torque delivery. Power and feedback connectors are integrated into a turnable connection housing within a range of 270°, allowing flexible installation without compromising cable routing or system layout. With no holding brake installed, the unit remains lightweight and can be paired with external braking solutions when required.
Designed to enhance reliability and streamline system integration, the MHD071A-061-NG0-UN offers exceptional durability thanks to its sealed shaft interface and liquid-cooled housing. Its precise digital feedback mechanism supports seamless compatibility with modern drive controllers, facilitating high-speed operation and rapid acceleration. The absence of an internal holding brake reduces maintenance complexity and provides designers the freedom to select braking systems tailored to specific applications. Overall, this servo motor ensures efficient energy use, stable thermal performance, and long-term operational integrity, making it ideal for robotics, CNC machinery, and other industrial automation solutions where precision and uptime are critical.

Frequently Asked Questions
How does the liquid-cooled housing in the MHD071A-061-NG0-UN affect long-term operation?
It dissipates heat more effectively than air cooling, allowing the motor to run at higher duty cycles. This reduces thermal stress on windings and extends service life in demanding applications.
What is the benefit of using a sealed shaft design with a shaft seal?
The seal prevents dust, oil, and coolant ingress into the motor. This protection is critical in CNC and machining environments where contaminants are common.
How does the winding code 061 influence efficiency?
The winding characteristics are optimized to balance torque output and electrical consumption. This helps achieve efficient torque delivery without excessive heating.
What should be considered when mounting the MHD071A-061-NG0-UN on machinery?
It uses a 115 mm flange and 95 mm centering diameter, so proper alignment is essential. Accurate mounting ensures minimal vibration and consistent shaft load distribution.
How does the compact motor size affect integration in multi-axis systems?
Smaller profiles enable closer spacing of axes in confined machine frames. This is especially useful in robotics or packaging systems with limited installation space.
