Description
Bosch Rexroth MSK076C-0450-NN-M1-UG1-NNNN | IndraDyn S Motor Key Spec, New In Stock
Architect’s Product Breakdown
The MSK076C-0450-NN-M1-UG1-NNNN servo motor acts as a high-capacity rotary actuator engineered for high-performance multi-axis motion systems. Driven by Bosch Rexroth IndraDrive controllers, this 076-frame C-stack variant delivers substantial continuous torque output, making it ideal for high-inertia loads in automated machining centers, printing presses, and heavy transfer lines. Its optical multi-turn absolute encoder maintains precise position tracking across power cycles without requiring manual homing routines.
Integrating this unit into existing machinery requires verifying drive firmware compatibility and ensuring the control loop gains are tuned to match the thermal and rotational inertia profiles of the 076-series frame. The “UG1” designation specifies an integrated shaft sealing ring, protecting the front bearing assembly against coolant and oil ingress in aggressive production environments.
Engineering teams must prioritize thermal management and shield grounding. Operating enclosed motors without adequate convective airflow or leaving power cable shields unbonded can cause thermal derating or electromagnetic interference across control channels.

Field Engineer’s Pitfall Guide
- Feedback Connector Misalignment: Forcing the circular feedback plug without aligning the internal keyway can bend delicate pins, triggering immediate absolute encoder communication faults on the drive.
- Neglecting Lip Seal Maintenance: While the UG1 integrated shaft seal protects against fluid migration, failing to monitor the seal for dry-running wear can cause premature friction breakdown in aggressive lubricant environments.
- Inadequate Power Cable Shield Grounding: Failing to secure the motor power cable shield 360 degrees to the drive chassis clamp introduces high-frequency noise that disrupts nearby low-voltage instrumentation loops.
QA & Testing SOP
- Visual & Origin Inspection: Verify factory seals, inspect housing coatings and shaft seal surfaces for transit damage, and check connector pin alignment against production documentation.
- Live Test Environment: Couple the motor to a calibrated IndraDrive test bench to verify smooth commutation, holding current stability, and velocity tracking under load.
- Diagnostics & Handshake Tests: Execute absolute encoder initialization routines, verify multi-turn position count registers, and perform a megohmmeter insulation resistance test on the windings.
- Preservation & Packaging: Install protective plastic caps over the shaft and connectors, wrap the unit in antistatic shielding material, and secure it inside heavy-duty industrial foam.
Technical FAQ
Does the MSK076C-0450-NN-M1-UG1-NNNN include an integrated holding brake?
No. The “-NN-” designation indicates that this specific configuration is supplied without an internal holding brake.
What is the difference between a UG0 and a UG1 shaft designation?
The UG0 designation represents a plain shaft without an integrated sealing ring, whereas UG1 includes an integrated shaft sealing ring for enhanced protection against fluid ingress.
Can I operate this motor using a third-party AC servo drive?
No. MSK motors use proprietary digital encoder communication protocols that require a compatible Bosch Rexroth IndraDrive controller for proper commutation and operation.
What software is required to configure the connected drive parameters?
Drive configuration, parameterization, and tuning are performed using the Bosch Rexroth IndraWorks engineering software platform.
