The Bosch Rexroth R911330886 (MSK071C-0300-NN-M2-UG0-RNNN) is an MSK series synchronous servo motor engineered for high-torque density and compact integration. It supports a maximum torque of 44.0 Nm and a peak continuous torque at standstill of 14.0 Nm (100 K), with a continuous standstill current of 8.5 A and maximum current of 32.9 A. The unit features a multiturn absolute optical encoder (EnDat2.1) with 2048 signal periods, and offers 240-degree rotatable connectors for both power and feedback connections. The motor uses natural convection cooling, optionally enhanced by surface cooling, and does not include a holding brake. A plain shaft with seal is supplied, and the motor has a DIN 42955-compliant housing for improved concentricity and run-out. It has a winding inductivity of 10,900 mH and weighs approximately 13.9 kg. Protection is rated at IP65.

Frequently Asked Questions

Why is natural-convection cooling advantageous in MSK071C-0300-NN-M2-UG0-RNNN?

Its passive cooling reduces parts count and removes blower maintenance while maintaining rated output in clean installations with adequate airflow. It simplifies enclosure design and improves reliability for continuous-duty axes.

How does the EnDat 2.1 multiturn encoder in MSK071C-0300-NN-M2-UG0-RNNN aid precision and diagnostics?

The digital, bidirectional EnDat protocol transmits absolute position plus encoder metadata over minimal lines for supporting reliable commissioning and advanced condition data. Its multiturn tracking preserves position across power cycles that streamlines homing for automated cells.

How does 10,900 mH winding inductivity influence current dynamics and drive tuning?

Its higher inductivity smooths current ripple and eases current-loop tuning for improving torque linearity at low speeds. Its drive can run with reduced switching ripple stress for aiding thermal behavior under cyclic loads.

What benefits arise from the rotatable 240° encoder connector on MSK071C-0300-NN-M2-UG0-RNNN?

The swiveling feedback connector eases cable routing in crowded cabinets or moving carriages to minimize bend radius violations. It also enhances serviceability when swapping feedback cables or adapting to different machine layouts.

How does IP65 sealing impact deployment environments and maintenance intervals?

The IP65 allows operation against dust ingress and low-pressure jets that enables use near coolants and paper dust in machine tools or printing. It reduces auxiliary guarding needs and extends service intervals.
