MSK071C-0300-NN-M2-UP1-RNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK071C-0300-NN-M2-UP1-RNNN is part of the MSK IndraDyn S Synchronous Motors and represents a high-performance Product Type IndraDyn S Synchronous Servomotor built for demanding motion control applications. It features a compact Motor Size 071 frame and a Motor Length C housing, optimized for minimal footprint. The drive interfaces seamlessly with standard three-phase inverters and supports a Rated Speed Code 0300 for precise speed regulation up to 300 rpm. Engineered with Design Increased concentricity, this servomotor guarantees superior rotor balance and minimized vibration.
Cooling and feedback integration are tailored for reliability: the MSK071C uses Cooling Natural convection for silent operation and requires no additional fans. Position detection is managed by an Encoder Technology Optical system with a Encoder Turn Type Multiturn Absolute design, ensuring position retention through power cycles. The feedback loop communicates via a high-precision Encoder Interface EnDat2.1 with Encoder Resolution 2048 signal periods and a Rotatable, 240° Encoder Connector for flexible routing. Mechanical security is provided by a robust Shaft Type Shaft with keyway and an integrated Holding Brake, electrically-released system that delivers Holding Brake Torque 23 Nm for safe standstill locking.
The MSK071C-0300-NN-M2-UP1-RNNN offers dynamic current and torque capabilities tuned for high performance: it provides Continuous Current at Standstill 100 K 8.5 A and maintains Continuous Torque at Standstill 100 K 14.0 Nm for static holding tasks. Under peak conditions, it can handle a Maximum Current 32.9 A and deliver up to Maximum Torque 44.0 Nm, making it suitable for rapid acceleration profiles. The rotor and stator windings exhibit a Winding Inductivity 10,900 mH, contributing to smooth current transitions and precise torque control in advanced automation systems.

Frequently Asked Questions
How do the 8.5 A standstill current and 14.0 Nm continuous standstill torque on MSK071C-0300-NN-M2-UP1-RNNN affect axis sizing?
They define continuous thermal load at zero speed for holding or feed. Its gear ratio, duty cycle and cooling must preserve margin before approaching the 32.9 A, 44 Nm peak limits.
Why is a multiturn absolute optical encoder with EnDat 2.1 used on MSK071C-0300-NN-M2-UP1-RNNN?
It preserves absolute position through power cycles and reports diagnostics over a digital link. Its EnDat 2.1 simplifies cabling to improve noise immunity and shortens commissioning versus incremental encoders with homing routines.
What is the practical effect of a 10,900 mH winding inductivity in the MSK071C package?
The inductance filters current ripple and linearizes torque for improving low-speed smoothness. It also limits current-loop bandwidth, so drive tuning must balance responsiveness against stability and PWM switching losses.
How does the electrically released, 23 Nm holding brake in MSK071C-0300-NN-M2-UP1-RNNN improve safety and startup?
The brake holds the axis unpowered and releases only when energized to prevent drift. Its capacity suits vertical axes and fixtures for mitigating sag during e-stop, jog and initial encoder alignment.
What benefits does the “increased concentricity” mechanical design bring to servo performance?
Its reduced runout lowers vibration and bearing load for enabling tighter position gains. Its better rotor balance reduces periodic disturbance that yields cleaner contour accuracy and improved surface finish on interpolated paths.
