Product Description:

The MSK070E-0450-NN-M2-UG1-RNNN belongs to the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. It is an AC servomotor built for closed-loop motion axes in packaging machines, printing lines, and general automation. The motor provides precise torque and position control so that actuators can follow demanding speed profiles without mechanical backlash. In servo systems, it is suited for applications that require repeatable motion, stable speed regulation, and accurate positioning during frequent acceleration and stopping cycles.

This model rejects heat through natural convection, eliminating the need for forced airflow or liquid circuits in most cabinets. Position feedback is generated by an optical encoder that produces 2048 signal periods per revolution and communicates with the drive over the EnDat2.1 serial interface. Because the measuring system is multiturn absolute, the controller knows the shaft angle after power loss, which removes the need for homing routines at startup. For static holding or emergency stops, an electrically released brake supplies 23 Nm of holding torque. This arrangement allows the axis to restart with position data already available to the drive.

The feedback cabling attaches through a rotatable 240° connector, allowing the housing to clear tight machine walls while preserving bending radii. Production to an increased concentricity standard minimizes radial runout so couplings can transmit torque with smoother alignment at the load side. A plain shaft interface enables direct clamping in pulleys or precision bellows couplers, and the 0450 winding is matched to compatible drive modules for the required voltage constant and current density. The adjustable connector position also helps when the cable path must avoid nearby guards, frame members, or other axis components.
