MSK071E-0450-NN-S1-UG0-NSNN

The Bosch Rexroth Indramat MSK071E-0450-NN-S1-UG0-NSNN synchronous servomotor from the MSK IndraDyn S Synchronous Motors series offers high-precision motion control with robust design for explosive environments. This manufacturer motor features a singleturn optical Hiperface encoder delivering 128 signal periods for accurate position feedback. Natural convection Cooling ensures maintenance-free heat dissipation in confined installations. The standard and explosion-protection Design provides reliable operation in Zone 2 potentially explosive areas. Its plain output Shaft Type and compact Motor Size 071 construction enable seamless integration into varied mechanical systems.

The motor’s electrical parameters include a Continuous Current at Standstill 100 K of 24.4 A and a Continuous Torque at Standstill 100 K of 28.0 Nm, ensuring steady holding performance. Peak acceleration demands are met with a Maximum Current of 90.1 A and a Maximum Torque of 84.0 Nm. The custom winding code 0450 yields a Winding Inductivity of 2,600 mH for controlled current ripple and torque smoothness. Encoder details are optimized for precision, with a rotatable Encoder Connector (240°) and optical Encoder Interface Hiperface technology supporting singleturn accuracy. The motor length designation E balances torque density and inertia.

Operational performance thrives within an ambient temperature range of 0 °C to 40 °C and a maximum absolute air humidity of 29 g/m³, safeguarding the motor under variable environmental loads. The thermal time constant of 19.8 minutes and thermal class 155 insulation rating enable consistent operation under heavy duty cycles. At altitudes up to 1000 meters above sea level, the motor maintains its Continuous Torque at Standstill 100 K without derating. Natural convection cooling combined with IP65-grade sealing ensures dust and splash resistance. Acoustic emissions remain low, generating approximately 75 dB at full speed.

System integration is simplified by the standard IndraDyn S interface, offering compatibility with Bosch Rexroth drive controllers and I/O modules. The explosion-protection version meets industrial safety standards, making it ideal for chemical, petrochemical, and pharmaceutical process lines. With its high-resolution encoder and robust torque capabilities, this servomotor excels in precise positioning applications, automated production cells, and critical safety systems. The compact part_number design supports retrofits and new installations where reliability and accuracy are paramount.
