MSK071D-0300-NN-S2-UG0-RNNN

The Bosch Rexroth Indramat MSK071D-0300-NN-S2-UG0-RNNN synchronous servomotor in the MSK IndraDyn S Synchronous Motors series delivers a robust and versatile solution for high-precision motion control. Engineered by Bosch Rexroth Indramat, this motor features a torque constant of 2.12 Nm/A at 20 °C and a winding resistance of 1.26 Ω, ensuring precise torque delivery and predictable thermal behavior. With an IP65 degree of protection, the unit is fully sealed against dust ingress and protected from low-pressure water jets, making it suitable for harsh industrial environments. Its plain shaft design combined with an integrated sealing ring and sealed housing guarantees long-term reliability under dynamic load conditions. The MSK071D-0300-NN-S2-UG0-RNNN supports a flange-mounted configuration for straightforward mechanical integration.

Detailed technical specifications underline the motor’s advanced capabilities: it employs an optical singleturn encoder with EnDat 2.1 interface, offering 2048 signal periods per revolution for high-resolution position feedback. Both power and feedback connectors are 240° rotatable to facilitate flexible cable routing. The motor’s cooling method is natural convection, eliminating the need for forced-air blowers. Constructed to DIN 42955 standards, the housing features increased concentricity and run-out for enhanced mechanical accuracy. Additional key parameters include Motor Size: 071 and Motor Length: D, with a housing length of 322 mm. The shaft is a plain shaft with a 32 mm diameter and 58 mm projection, and the flange measures 150 mm with four 11 mm mounting holes. The nominal winding code is 0300.

Operational performance is optimized for demanding applications: the motor delivers a continuous torque at standstill (100 K) of 20.0 Nm at continuous current (100 K) of 10.7 A, and can handle a maximum torque of 66.0 Nm at maximum current of 40.5 A. The high winding inductivity of 10,700 mH ensures smooth current transitions and low ripple during dynamic acceleration. The unit operates reliably over ambient temperatures from 0 to 40 °C and up to 1000 m elevation above sea level, maintaining consistent performance without additional cooling devices. The natural convection cooling method simplifies installation and reduces maintenance requirements.

System integration is seamless via the EnDat 2.1 encoder interface, enabling compatibility with modern drive controllers and motion PLCs. The sealed connectors and IP65 housing support washdown processes and strict hygiene standards in food or pharmaceutical production. An optional holding brake, available separately in 23 Nm and 30 Nm variants, can be fitted to provide secure stopping and holding capability. The MSK071D-0300-NN-S2-UG0-RNNN is ideally suited for CNC machining centers, robotics, automated assembly lines, and packaging machinery where precision, robustness, and ease of integration are critical.
