The Bosch Rexroth synchronous servomotor, MPN R911318419 (MSK071C-0300-NN-M1-UG1-NNNN), is a standard-design IndraDyn S motor equipped with an optical Hiperface multiturn absolute encoder, offering 128 signal periods and a 240° rotatable connector. It features a plain shaft, standard insulation system, and protective components for transport and assembly. This unit operates within a temperature range of -20°C to 80°C, with continuous standstill current of 8.5 A, continuous torque at standstill of 14.0 Nm, peak current of 32.9 A, and maximum torque of 44.0 Nm. The winding inductivity is 10,900 mH. The holding brake is electrically released with a holding torque of 23 Nm. The motor is cooled by natural convection and has a size code 071 and length C. Heat resilience can be affected by housing contamination. Exposure to saline environments, extreme cold, or direct sunlight should be avoided during use, storage, or transport. The holding brake is not intended for personal protection purposes.

Frequently Asked Questions

How does the M1 Hiperface multiturn encoder on the MSK071C-0300-NN-M1-UG1-NNNN improve commissioning and recovery after power loss?

The M1 provides absolute position across 4096 revolutions with 128 periods per turn, so axes wake aligned without homing. It accelerates startup, preserves reference and reduces fixture wear.

Why is natural-convection cooling advantageous for the MSK071C-0300-NN-M1-UG1-NNNN in sealed cabinets, and when consider blowers/liquid cooling?

Its passive heat rejection avoids fan maintenance and helps preserve IP65 sealing. For elevated continuous thermal loads, Rexroth offers axial/radial blowers or liquid-cooling options to raise permissible duty and continuous torque.

What does the 10,900 mH winding inductivity in MSK071C-0300-NN-M1-UG1-NNNN do in fast-switching PWM drives?

The higher inductivity lowers current ripple and attenuates switching harmonics for improving torque smoothness at lower electrical time constants. It also eases EMC compliance and mitigates audible noise under steep edge rates.

How is the electrically released 23 Nm holding brake on MSK071C-0300-NN-M1-UG1-NNNN applied in vertical axes or emergency stops?

The loss of supply engages the brake to hold position against gravity or drift during faults. During motion, the drive energizes it for supporting STO chains and controlled deceleration strategies.

How do the 240° rotatable power/encoder connectors on MSK071C-0300-NN-M1-UG1-NNNN affect multi-axis routing and serviceability?

It aligns exits with trunking to minimize bend radii and crossovers in dense cabinets. It also allows connector access without dismounting the motor for reducing service time in enclosed frames.
