The Bosch Rexroth synchronous servomotor, MPN R911329205 (MSK071C-0200-NN-S2-UG1-RNNN), features a plain shaft design and utilizes natural convection for cooling. It is equipped with an optical single-turn EnDat2.1 encoder providing 2048 signal periods of resolution and a rotatable 240° connector. The motor achieves a continuous torque of 18 Nm at standstill (14 Nm at 100 K), with a continuous current uptake of 7.8 A (6.1 A at 100 K), a maximum torque of 44 Nm, and a maximum current of 23.4 A. Electrical specifications include a winding resistance of 3.10 ohms and an inductance of 19,500 mH. The rotor torque constant is 2.50 Nm/A and the moment of inertia is 0.00173 kg·m². The integrated holding brake delivers 23 Nm of torque and is electrically released. This model has increased concentricity, a weight of 13.9 kg, IP65 protection class, and insulation class 155. Installation and operation should follow the user manual and be performed by qualified personnel.

Frequently Asked Questions

What does the “S2” encoder on MSK071C-0200-NN-S2-UG1-RNNN provide, and how does it affect servo accuracy?

It’s an optical singleturn EnDat 2.1 absolute encoder with 2048 signal periods to give precise absolute position over one revolution and robust digital communication. It improves loop stiffness, commutation accuracy and repeatability when paired with IndraDrive controls.

How is the 23 Nm electrically released holding brake on MSK071C-0200-NN-S2-UG1-RNNN intended to be used?

The brake is electrically released at 24 V DC and intended to hold a static axis at standstill. Its size-matched 23 Nm static torque secures vertical or offset loads.

How does the ~19.5 mH winding inductance of MSK071C-0200-NN-S2-UG1-RNNN influence current-loop tuning and EMC?

The higher inductance raises the electrical time constant, smoothing PWM ripple and easing EMI filtering. It also constrains current-loop bandwidth.

Which torque/current figures define continuous versus transient operation for MSK071C-0200-NN-S2-UG1-RNNN?

The 071C-0200 winding and M0(100 K) = 14.0 Nm @ 6.1 A defines continuous standstill capability, while Mmax = 44.0 Nm @ 23.4 A defines peak. Its drive current limits and thermal models keep operation within these regions.

Which industries commonly deploy MSK071C-0200-NN-S2-UG1-RNNN, and why?

The MSK series motors are used in machine tools, printing/paper, packaging/food, metal forming and handling/robotics where precision and washdown-resistant enclosures matter. It offers IP65 protection and multiple cooling/encoder options to match environment and accuracy demands.
