The R911276843 (MHD071B-035-NG0-UN) is a Bosch Rexroth servo motor designed with a brushless configuration and fully sealed housing rated to IP65, suitable for demanding environments. It features liquid cooling and incorporates a temperature monitoring system for overload protection. This unit provides continuous torque at standstill of 8.0 Nm, a plain shaft with seal, and a B-length size. The centering diameter is 95 mm with a 115 mm flange size. Position detection uses a digital servo feedback encoder (HSF), operating in relative mode. Power and feedback connectors are provided, with the power connection direction adjustable within 270°. No holding brake is included.

What type of feedback system does the MHD071B‑035‑NG0‑UN use for position control?

It uses a digital HSF encoder with relative position detection, suitable for closed-loop motion control. This ensures reliable tracking in applications where homing can be performed at startup.

What kind of shaft coupling is ideal for this plain shaft design?

A keyless, friction-fit or clamping-style coupling is generally preferred for plain shafts. It reduces backlash and simplifies maintenance in precision-driven applications.

Can this motor be mounted in any orientation given the cooling method?

Yes, but mounting should ensure coolant flow paths remain unrestricted. Vertical mounting may require special plumbing to prevent air locking in the cooling jacket.

Does the turnable power connector offer any installation advantages?

Yes, the 270° rotatable connector allows flexible cable routing in space-constrained setups. This reduces strain on cables and simplifies integration into enclosures.

Is the motor suitable for precision applications despite relative position detection?

Yes, if paired with systems that allow homing or use external encoders for absolute reference. It remains effective in repeatable cycle operations like pick-and-place.
