MSK070C-0450-NN-S2-UP1-RNNN

The MSK070C-0450-NN-S2-UP1-RNNN synchronous servomotor by Bosch Rexroth Indramat belongs to the renowned MSK IndraDyn S Synchronous Motors series, offering a compact yet powerful solution for precise motion control. Designed with a motor size of 070 and a motor length designation C, this unit delivers continuous torque at standstill of 14.5 Nm at 100 K and continuous current at standstill of 13.7 A. The winding is identified by the winding code 0450, featuring a winding inductivity of 4.0 mH and a leakage capacitance of 3.1 nF to optimize electromagnetic performance. The servomotor integrates a robust shaft with keyway for secure coupling and a holding brake, electrically released, capable of 23 Nm holding brake torque to maintain position under load. Weighing just 11.7 kg and rated for a maximum rotational speed of 6000 rpm, this unit balances power density with ease of installation.

Performance is driven by a maximum torque of 33.0 Nm under a maximum current of 36.9 A, ensuring rapid acceleration and dynamic response. Precision feedback is provided through an optical encoder technology featuring EnDat 2.1 interface, rotatable 240° encoder connector, and 2048 signal periods singleturn resolution for sub-micrometer positioning. The motor achieves a torque constant of 1.16 Nm/A and a voltage constant of 71.3 V/1000 min⁻¹, supporting efficient energy conversion across its speed range. Thermal behavior is managed by a thermal time constant of 31 minutes and natural convection cooling, while the thermal class F (155) insulation ensures durability under continuous operation. Acoustic emissions remain below 75 dB(A) at full load, making the motor suitable for noise-sensitive environments.

Engineered for reliability, the MSK070C-0450-NN-S2-UP1-RNNN meets IP65 protection level standards, offering resistance against dust and water ingress in harsh industrial settings. The increased concentricity design minimizes vibration and mechanical stress, extending service life and reducing maintenance intervals. Installation is simplified by adherence to standard Bosch Rexroth mounting specifications, including recommended fasteners and altitude limits up to 1000 m above sea level. Integration with the IndraDyn S drive platform unlocks advanced functions such as auto-tuning, vibration suppression, and torque ripple compensation, enabling seamless incorporation into robotics, packaging machinery, and multi-axis CNC systems. Overall, this servomotor provides a dependable, high-performance foundation for demanding automation and motion control applications.
