MHD071B-035-NG1-UN
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD071B-035-NG1-UN servo motor from the MHD Synchronous Motors series is a high-precision synchronous servo motor featuring liquid cooling with a housing design for natural convection or surface cooling. It delivers a continuous torque at standstill of 8.0 Nm and a holding brake torque of 5.0 Nm. The motor size 071, length B, centering diameter 95 mm and flange size 115 mm ensure robust integration. Rated speed of 2500 RPM is monitored via a digital servo feedback (HSF) encoder with relative position detection. Its plain shaft includes a shaft seal, and IP65 protection rating guarantees environmental resistance. Power and feedback connectors are turnable within a range of 270°, enhancing installation flexibility.

Frequently Asked Questions
What are the integration considerations for a flange size of 115 mm?
A 115 mm flange allows compatibility with standard industrial mountings. It also ensures stable mechanical coupling in high-torque applications.
Is the MHD071B-035-NG1-UN suitable for vertical mounting applications?
Yes, especially with its integrated holding brake rated at 5.0 Nm. It helps maintain position when power is removed, critical for vertical loads.
Why is the centering diameter important when selecting a servo motor?
The centering diameter ensures precise alignment between motor and driven equipment. Poor alignment increases wear and reduces transmission efficiency.
How does a rated speed of 2500 RPM influence system design?
A 2500 RPM speed supports fast cycle times in dynamic applications. It must be matched with gearbox ratios and load inertia for optimal results.
Can the MHD071B-035-NG1-UN handle continuous-duty operations?
Yes, its continuous torque capability at standstill and liquid cooling allow sustained performance. It is well-suited for high-duty cycle automation tasks.
