Product Description:
The MSK070E-0450-NN-S2-UG1-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a permanent-magnet AC unit, it delivers closed-loop positioning and speed control for automated machinery where compact torque density is required. The motor occupies size 070 with length code E and uses a plain shaft to transmit motion directly to couplings or gear stages in packaging lines, pick-and-place axes, or forming stations. Its synchronous operating principle allows the paired drive to regulate speed and position with quick response during repeated start-stop motion.
This model relies on natural convection to remove heat, so no external fan or liquid circuit is needed during operation within the ambient range of 0–40 °C. The aluminum housing carries an IP65 rating that blocks dust ingress and low-pressure water jets, allowing cabinet-free mounting near the work zone. The motor uses an increased concentricity design to reduce runout and help the rotor stay balanced at high acceleration. A rotatable encoder connector that sweeps through 240° simplifies cable routing in tight enclosures. Thermal stability is supported by insulation class 155, and winding code 0450 indicates the electrical values of the stator coils used by the matching drive.
Feedback is provided by an EnDat2.1 optical single-turn encoder that generates 2048 signal periods per revolution, giving precise position data to the drive controller. The optical sensing path resists magnetic interference common near high-current busbars and supports stable signal transmission. A spring-applied, electrically released brake supplies 23 Nm of holding torque, securing vertical loads when power is removed. This brake helps keep the axis in place during stops, while the plain shaft and rotatable connector support integration with external transmission components.
