Product Description:

Bosch Rexroth Indramat manufactures the MSK050B-0450-NN-M1-UP0-NNNN as part of the MSK IndraDyn S Synchronous Motors series. The motor provides precise torque and position control for automated pick-and-place units, packaging axes, and CNC tooling. Through closed-loop feedback, the unit supports repetitive motion profiles and tight path tracking, making it a common drive element in multi-axis factory cells and material-handling gantries.

The housing releases waste heat by means of natural convection, so no fan or liquid circuit is required and cabinet airflow remains undisturbed. A power and feedback plug that is rotatable through 240° allows cable routing toward a duct or trough without twisting the harness. Position data travels over the Hiperface bidirectional interface, allowing the drive controller to read absolute position at startup and write calibration offsets as needed. Inside the feedback assembly, an optical scanning method detects code tracks etched on the disk, producing low-jitter signals for stable velocity loops. The scale contains 128 signal periods, so every mechanical revolution is divided into 8192 discrete counts after interpolation, providing fine granularity for contouring applications that demand sub-arc-minute repeatability.

Mechanical integration centers on a shaft with keyway that mates directly with keyed couplings or pulleys to prevent slip under reversing loads. The frame is size 050 with length code B, giving the motor a compact envelope while retaining continuous torque consistent with the 0450 winding variant. The motor is supplied without a holding brake, so holding torque must be provided externally when the axis is at rest. The 0450 winding code matches coil impedance to standard IndraDrive amplifiers, providing electrical compatibility without additional filtering or matching networks.
