Product Description:

Bosch Rexroth Indramat manufactures the MSK071E-0450-NN-S2-UG1-RNNN, an IndraDyn S synchronous servomotor from the MSK series. In automated machinery, it delivers controlled torque and precise position feedback to axis drives, acting as the electromechanical link between the drive amplifier and the mechanical load. The unit fits multi-axis systems where compact dimensions, high encoder accuracy, and maintenance-friendly features support precise motion and straightforward installation.

The motor’s enclosure is rated at IP65, so dust ingress is prevented and water jets do not affect internal components during washdown cycles. Heat is removed by natural convection, eliminating fans and allowing installation without external airflow guides. Position data are transmitted through the EnDat 2.1 serial interface, and the optical encoder provides 2048 signal periods per revolution in a single-turn format; this resolution supports fine velocity loops at the drive controller. A rotatable 240° encoder connector eases cable routing in tight spaces, while the increased concentricity design helps minimize runout at higher speeds. An electrically released holding brake supplies 23 Nm of static torque to secure axes during power-off events.

The mechanical drive side uses a plain shaft that mates with backlash-free couplings or timing belt pulleys, and the shaft geometry aligns with the series 071 frame code and length E housing. Continuous operation is specified within an ambient range of 0 to 40 °C, so the motor can be installed in standard control rooms without forced cooling. Coil insulation follows class 155, enabling winding temperatures up to 155 °C before thermal derating occurs. The electromagnetic circuit uses winding code 0450, which gives the matching drive the proper voltage-current profile for servo tuning and peak torque allocation.
