MSK071D-0450-NN-S1-BG0-NNAN

The MSK071D-0450-NN-S1-BG0-NNAN by Bosch Rexroth Indramat is a high-performance servomotor within the MSK IndraDyn S Synchronous Motors series, engineered for demanding industrial automation. This robust device delivers a maximum current of 69.3 A and a maximum torque of 66.0 Nm, ensuring reliable power density for dynamic load conditions. With a compact motor size of 071 and a framed motor length of D, the unit maintains a low-profile footprint while weighing just 18 kg. The motor features a leakage capacitance of 7.8 nF, contributing to electromagnetic compatibility in sensitive control environments. Its product type as an IndraDyn S synchronous servomotor positions it as an ideal choice for precision motion applications.

The technical configuration of this servomotor underscores its advanced capabilities: an optical encoder technology with encoder interface Hiperface provides high-fidelity feedback, utilizing a singleturn encoder turn type and delivering a encoder resolution of 128 signal periods. The stator winding follows a precise winding code of 0450 with a winding inductivity of 3,200 mH, optimizing current flow and response time. Continuous operation at standstill is rated at 17.6 A, generating a stall torque of 20.0 Nm at 100 K, while the shaft-mounted radial sealing ring safeguards against contaminants. Passive cooling is achieved through natural convection, allowing maintenance-free temperature regulation under typical ambient conditions. A plain shaft configuration without holding brake simplifies mechanical coupling and reduces inertia.

Operational excellence is assured by multiple design features: the absence of a holding brake reduces wear and improves responsiveness, while the robust power connector on the B-Side permits streamlined cable routing in compact assemblies. The motor’s thermal management benefits from a natural convection scheme, resulting in consistent performance without auxiliary cooling systems. An integrated encoder data memory stores threshold warnings and shutdown temperatures, protecting the unit from overtemperature scenarios and drive controller faults. The unit’s maintenance procedures are simplified by its resistance to excessive dust and chip deposition, although regular cleaning is recommended to maintain performance. Safety is enhanced through the use of an Hiperface redundant feedback loop, ensuring reliable position data under high dynamic loads.

Integration into multi-axis systems is facilitated by the motor’s compact design and standardized mounting interfaces, enabling straightforward installation in robotic arms, CNC machines, and conveyor systems. Compatibility with Bosch Rexroth IndraDrive controllers allows seamless parameterization of torque constants, current limits, and encoder settings via electronic nameplate data. The servomotor’s plain shaft and radial sealing ring support various couplings and gearboxes, extending its applicability to machine tools, packaging equipment, and assembly lines. Its robust construction and high electromagnetic compatibility make it an excellent candidate for environments requiring precise motion control and low electromagnetic interference.
