Product Description:

The MSK101E-0450-NN-M2-BP2-RNNN belongs to the MSK IndraDyn S Synchronous Motors series produced by Bosch Rexroth Indramat. It is an AC servomotor used for precise position and speed control in automated machinery, where closed-loop feedback and high torque density are required for accurate axis response. The model combines a compact 101 frame with an E-length stator to provide repeatable motion in packaging, handling, and machining cells. This layout supports stable servo response on axes that must start, stop, and reverse direction with consistent accuracy during normal machine cycles.

The motor dissipates heat through natural convection, so the installation must allow free airflow around the housing to keep winding temperature within limits. Position data is delivered by an optical encoder that communicates via the EnDat2.1 interface. Inside the measuring head, the disk generates 2048 signal periods, which the controller interpolates for fine positioning. Because the sensing element is multi-turn absolute, it reports both shaft angle and total revolution count after power loss. This arrangement helps the drive retain accurate axis status between restarts and supports smooth closed-loop motion. An electrically released holding brake supplies up to 70 Nm of static torque, so vertical or suspended axes remain locked when the drive is disabled.

The mechanical build features increased concentricity to limit radial runout, which helps improve repeatability during acceleration and reversing movements. This can also reduce coupling misalignment effects at the load interface. Power conductors exit on the B-side, which can simplify cable routing when the machine layout requires separation between power and feedback paths. Torque is transmitted through a shaft with a keyway, allowing standard keyed couplings to be installed without special adapters. The stator uses winding code 0450, which matches the voltage and current characteristics expected by the associated drive.
