The Rexroth Indramat R911276749 (MHD041A-144-PG0-UN) is a servo motor from the MHD series, featuring an 82 mm flange and 50 mm centering diameter. Classified as size 041, length category A, this motor delivers a continuous standstill torque of 1.3 Nm and handles a rated speed of 4,000 rpm (540 VDC), with a maximum speed of 7,500 rpm and theoretical maximum torque of 5.6 Nm. It employs liquid cooling and a shaft with seal, uses digital servo feedback with an integrated multi-turn absolute encoder, and does not include a holding brake. Moment of inertia is 0.88 × 10⁻⁴ kg·m², with winding inductance at 13.5 mH and a peak current of 15.8 A. Power and feedback connections are rotatable within 270°. Suitable for environments ranging from -20°C to 80°C in storage or transport, and up to 40°C in operation. Over-temperature classes are 60K and 100K.

Frequently Asked Questions

What installation flexibility does the MHD041A-144-PG0-UN offer for cabinet layouts?

Its turnable power connector allows up to 270° adjustment, simplifying cable routing. This reduces space conflicts in compact control cabinets.

How does liquid cooling affect the long-term operation of this servo motor?

Liquid cooling keeps winding temperatures stable under peak demand. This extends service life and maintains consistent torque output.

Why is the encoder’s absolute position detection important?

Absolute feedback eliminates the need for homing on restart. This ensures immediate accuracy and minimizes downtime after power cycles.

What applications benefit most from the MHD041A-144-PG0-UN’s torque capability?

Its 1.3 Nm continuous torque suits precise pick-and-place tasks, light robotics, and indexing drives. These applications demand repeatable accuracy at standstill.

What effect does the encoder’s high resolution have on motion control?

It enables smoother interpolation in multi-axis systems. This is critical for synchronized robotics and precision machining operations.
