MSK071C-0450-NN-M2-UG1-RNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK071C-0450-NN-M2-UG1-RNNN motor is part of the MSK IndraDyn S Synchronous Motors series and designed for high-precision motion control in industrial servo systems. As a IndraDyn S Synchronous Servomotor, it delivers a continuous torque at standstill of 14.0 Nm and draws a continuous current at standstill of 10.4 A under natural convection cooling. This robust design ensures reliable kinetic energy generation and precise positioning for applications ranging from metal forming to handling systems.
Incorporating advanced technical features, the MSK071C-0450-NN-M2-UG1-RNNN boasts a maximum torque of 44.0 Nm and can withstand a maximum current of 40.1 A. The winding inductivity is rated at 6,700 mH, optimizing the motor’s electrical responsiveness. The encoder subsystem utilizes Optical technology with an EnDat2.1 interface, a rotatable 240° connector, and offers 2048 signal periods with multiturn absolute resolution. The motor’s plain shaft includes a sealing ring to prevent mechanical play, and the design emphasizes increased concentricity for reduced vibration and enhanced accuracy.
Additional features include an electrically released holding brake with 23 Nm of torque for secure stoppage and safety during power loss. The motor’s plain shaft construction and natural convection cooling ensure low maintenance and high operational uptime. Compatibility with standard EnDat2.1 controllers and a resilient design make this servomotor ideal for continuous duty in harsh industrial environments. Users benefit from improved efficiency, superior positional accuracy, and long service life when integrating this motor into automated production lines.

Frequently Asked Questions
How does the optical EnDat 2.1 multiturn encoder (2048 periods) on the MSK071C-0450-NN-M2-UG1-RNNN improve servo accuracy and diagnostics?
It gives high-resolution absolute position across revolutions for eliminating homing and stabilizing low-speed motion. Its EnDat 2.1’s bidirectional link exposes status/error bits and parameters, aiding commissioning, condition monitoring and closed-loop integrity checks.
What does “14.0 Nm continuous torque at standstill (100 K) at 10.4 A” mean for vertical-axis holding on MSK071C-0450-NN-M2-UG1-RNNN?
It means the motor can continuously generate 14 Nm in thermal equilibrium with natural convection when driven at 10.4 A RMS. Its integrated 23 Nm spring-applies for power-loss parking and electrically released brake provides mechanical holding capacity.
Why is the 6,700 mH winding inductivity significant on MSK071C-0450-NN-M2-UG1-RNNN?
The greater inductivity attenuates current ripple for improving torque smoothness and easing current-loop tuning for field-oriented control. Its trade-off is a longer electrical time constant that drives must accommodate with bandwidth, decoupling and feed-forward strategies.
How do the plain shaft with sealing ring and increased concentricity option affect coupling performance on MSK071C-0450-NN-M2-UG1-RNNN?
The sealing ring mitigates ingress and oil migration for protecting front bearings and couplers. Its elevated concentricity reduces runout for enhancing alignment for bellows or elastomer couplings and lowering vibration in precision indexers and gear stages.
What are the duty-cycle implications of natural-convection cooling, and when would surface or liquid cooling be preferable?
The natural convection supports continuous duty within the stated thermal class but limits overload duration compared with surface/liquid-cooled variants. Its alternative cooling are available for higher continuous torque density or tighter thermal margins.
