MSK071D-0300-NN-M2-UP2-RNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK071D-0300-NN-M2-UP2-RNNN is part of the MSK IndraDyn S Synchronous Motors series, designed as an advanced IndraDyn S Synchronous Servomotor for precision motion control. With a motor size of 071 and motor length designation D, this unit delivers a continuous torque at standstill 100 K of 20.0 Nm and a maximum torque of 66.0 Nm, making it ideal for applications requiring high static and dynamic performance. The natural convection cooling system ensures reliable thermal management without additional auxiliary cooling components. Its primary function is to provide accurate, high-torque rotational motion in automated machinery and positioning systems.
Featuring an optical encoder technology with a multiturn absolute turn type, this servomotor integrates a rotatable encoder connector (240°) and supports the high-precision EnDat 2.1 interface. The encoder resolution of 2048 signal periods enables fine position detection and minimal error accumulation. The design emphasizes increased concentricity for reduced vibration and noise. Winding inductivity is rated at 10,700 mH, balancing current response and stability. The motor operates at a continuous current at standstill 100 K of 10.7 A and can handle a maximum current of 40.5 A, offering robust electrical performance under varying loads.
This model is equipped with a shaft with keyway for secure coupling and includes a holding brake (electrically released) with a holding brake torque of 30 Nm, ensuring safe stops and positional retention during power loss. The servomotor requires additional cooling FN for extended high-load duty cycles, meeting stringent industrial durability requirements. Its compliance with Bosch Rexroth design standards and requirement for external cooling underscores its adaptability in modular automation systems. In industrial applications, this servomotor delivers exceptional efficiency, precise torque control, and reliable operation, contributing to reduced downtime and optimized process throughput.

Frequently Asked Questions
How does the rotatable encoder connector improve installation flexibility?
The design allows adjustment up to 240 degrees. The flexibility simplifies cable routing in space constrained machine layouts.
Why is increased concentricity important in synchronous servomotors?
The feature reduces vibration during high speed operation. The result is smoother motion and longer bearing life.
How does the holding brake improve safety during machine stops?
The brake locks the shaft when power is removed. The mechanism prevents drift or movement that could damage tools or products.
In what types of automation systems would a torque capacity up to 66 Nm be beneficial?
The capability supports heavy load handling in packaging presses and cutting equipment. The strong torque output also improves acceleration in robotic axes.
How does winding inductivity influence the electrical performance of the motor?
The high inductivity smooths current flow. The effect reduces overshoot and stabilizes performance under dynamic load changes.
