MSK070C-0300-NN-S2-UP0-RSNN

The Bosch Rexroth Indramat MSK070C-0300-NN-S2-UP0-RSNN is a high-performance synchronous servomotor in the MSK IndraDyn S Synchronous Motors series, designed for precision motion control in demanding industrial environments. This Bosch Rexroth Indramat MSK070C-0300-NN-S2-UP0-RSNN model delivers consistent performance with a torque constant of 1.74 Nm/A at 20°C, producing robust dynamic response across a broad operating range. It features a sound pressure level of ~75 dB(A) and six pole pairs for optimized electromagnetic efficiency. The integrated optical encoder system, Singleturn EnDat2.1 with 2048 signal periods per revolution, ensures accurate position and speed feedback without external calibration or battery backup. Built for safety, the motor meets explosion protection standards and is certified for use in hazardous zones.

Detailed technical specifications reflect the motor's robust design. It operates with a continuous current at standstill of 9.2 A and a continuous torque at standstill of 14.5 Nm at 100 K, while accommodating a maximum current of 32.8 A and generating a maximum torque of 33.0 Nm. The winding inductivity of 8300 mH provides smooth current transition and torque ripple minimization. The motor's winding code 0300 and motor size 070 correspond to a compact length designation "C". Encoder connectivity is managed via a rotatable Encoder Connector (240°) and power/encoder interfaces conform to RLS1200/RGS1000 standards. Cooling is achieved through natural convection, eliminating the need for external fans.

Operational features emphasize reliability and maintenance-free performance. The self-cooling design expels heat through the housing, supporting continuous operation between 0°C and 40°C ambient temperature. A built-in temperature sensor provides thermal overload protection, while a maximum permitted shock load of 6 ms protects internal bearings and windings. Increased concentricity in the shaft assembly and a keyway per DIN 6885-1 ensure minimal vibration and precise torque transmission. With a bearing lifetime of 30,000 operating hours, the motor operates without scheduled maintenance under standard conditions.

System integration is simplified through compatibility with Bosch Rexroth Indramat servo drives and controllers, facilitating seamless communication via the EnDat2.1 encoder interface. The MSK070C-0300-NN-S2-UP0-RSNN excels in applications requiring high positioning accuracy and dynamic performance, including machine tools, printing and paper processing equipment, packaging lines, food processing machinery, metal forming systems, and robotics. Its explosion-protected design makes it suitable for hazardous environments in chemical or pharmaceutical production, where both precision and safety are paramount.
