The Bosch Rexroth Indramat MSK070D-0300-NN-M2-UP0-RNNN synchronous servomotor from the MSK IndraDyn S Synchronous Motors series delivers a compact yet powerful solution for demanding industrial automation tasks. This brushless, natural convection cooled unit features an advanced optical encoder and precision mechanics to achieve high dynamic response and operational efficiency. With a robust shaft with keyway and specialized sealing ring, the MSK070D’s mechanical design ensures reliable torque transmission under continuous duty. Engineered without a holding brake, this model prioritizes simplicity and serviceability while sustaining performance at elevated temperatures. The increased concentricity design contributes to reduced vibration and noise, supporting applications that demand precision and endurance.
The MSK070D-0300-NN-M2-UP0-RNNN’s electrical characteristics include a continuous current at standstill (100 K) of 12.6 A and a continuous torque at standstill (100 K) of 20.0 Nm, with a maximum current of 33.0 A and a maximum torque of 52.5 Nm under peak conditions. Winding inductivity is rated at 6,000 mH, while the standardized winding code 0300 ensures interchangeability across the MSK70D frame. The motor’s encoder interface EnDat2.1 communicates high‐resolution feedback, with an encoder resolution of 2048 signal periods and multiturn absolute encoder technology for precise position tracking. The rotatable encoder connector, 240°, simplifies cabling in confined installations. The motor’s nominal size 070 and motor length designation D facilitate system planning by standardizing mounting envelopes.
Operational resilience is achieved through natural convection cooling, eliminating the need for auxiliary fans or liquid cooling loops in many environments. The brushless design maintains up to 95% efficiency, reducing thermal losses, while the integrated grease-lubricated ball bearings manage residual heat via convection and conduction to the housing. With no holding brake, the MSK070D focuses on continuous operation in high-dynamic-index machines, minimizing maintenance points. The optimized concentricity and low rotor inertia enhance acceleration and deceleration characteristics, delivering rapid response times in metal forming, pick-and-place robotics, and high-speed indexing applications.
System integration is streamlined through compatibility with the Bosch Rexroth IndraDrive or IndraControl platforms, offering real-time motion control, parameter storage, and diagnostic monitoring. The MSK IndraDyn S series supports standardized mounting interfaces and electrical connections, reducing commissioning time in multi-axis systems. Its plain steel shaft and keyway design allow direct coupling to gearboxes or torque arms without additional adapters. Target applications include metal press automation, robotic assembly cells, paper converting machinery, and any high-precision process demanding reliable torque delivery and seamless network integration.
