Product Description:

The MSK076C-0450-NN-M1-UG1-NNNN belongs to the MSK IndraDyn S Synchronous Motors series produced by Bosch Rexroth Indramat. As an IndraDyn S synchronous servomotor, it converts controlled electrical power into precisely regulated rotary motion. This makes it suitable for positioning axes, gantries, and packaging machinery that depend on repeatable speed and torque profiles. In closed-loop operation, the connected drive can use motor feedback to correct speed and position deviations during acceleration and changing load conditions.

This model relies on natural convection for thermal dissipation, so airflow around the housing must be maintained to keep winding temperatures within safe limits in continuous duty. Position feedback is delivered through a Hiperface interface that carries both incremental and absolute data to the drive over a single cable, reducing wiring complexity. The optical measuring system inside the encoder generates 128 signal periods per mechanical revolution, providing the base count that the drive interpolates for fine position control. The encoder is a Multiturn Absolute type, so it stores shaft revolution counts even when power is removed and eliminates homing cycles at startup. An electrically released holding brake provides a static torque of 11 Nm, permitting the motor to secure vertical loads or maintain tooling position when the drive is disabled.

The motor uses a Plain shaft, which simplifies the connection to clamp hubs or shrink discs and helps reduce torsional backlash. Frame code 076 corresponds to the stator diameter, offering a balance between torque density and a compact footprint, while length code C indicates the third-longest active stack in the family and increases continuous torque relative to shorter variants. The electromagnetic characteristics are determined by winding code 0450, which aligns the voltage constant and rated speed with common 400 V class inverters used on modular drive platforms.
