Product Description:
The MSK101D-0450-NN-S2-AG2-RNNN servomotor is produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts electrical energy into controlled torque and speed for positioning tasks in automated machinery. The D-length, size-101 frame combines permanent-magnet rotor technology with a plain shaft to couple directly to gearboxes or mechanical loads, making it a compact actuator for numerically controlled axes.
Thermal management is based on natural convection, so the housing must be mounted where free airflow can remove heat without external fans. The Cooling FN designation indicates that supplemental cabinet airflow may be required. Position feedback is generated by an optical encoder that offers EnDat2.1 serial communication, allowing high-speed parameter transfer to the drive. The encoder provides 2048 signal periods per revolution and operates in a single-turn format, giving absolute position within one mechanical turn without additional batteries. An electrically released holding brake supplies 70 Nm of static torque, letting vertical or suspended axes hold position when power is removed.
The shaft is a plain shaft, machined for low runout in line with the increased concentricity design, and the protection rating of IP65 seals the housing against dust ingress and low-pressure water jets. Winding code 0450 identifies the stator turns that shape torque and voltage constants, while the motor’s thermal class is 155, allowing a high winding temperature limit before insulation aging accelerates. Operation is specified within an ambient range of 0 to 40 °C, so installation outside controlled enclosures may require derating or forced cooling. Power enters on the A-side connector, and the unit’s D-length frame preserves axial space while delivering the torque needed for medium-to-large gantry axes.
