REXROTH MSK076C-0450-NN-M1-UG1-NNNN High – Performance Servo Motor

Description

In dynamic industrial automation setups where rapid acceleration and precise load handling define efficiency, the Bosch Rexroth MSK076C-0450-NN-M1-UG1-NNNN emerges as a targeted ally for engineers wrestling with torque inconsistencies or encoder lag in compact, high-response systems. Visualize a high-speed winding machine in cable production where momentary speed dips cause tension breaks and scrap, or a robotic palletizer where position errors under varying payloads lead to stacking faults—these setbacks often stem from motors that compromise on density or feedback resolution under real-time stresses. This synchronous servo motor counters them with its permanent magnet rotor and Hiperface multiturn encoder, supplying absolute position data across 128 increments per turn for up to 4096 revolutions, ensuring I/O signals remain sharp and control algorithms execute without interpolation delays.

It holds particular value in process control applications like textiles or electronics assembly, where high reliability in motion feedback underpins defect-free output and cycle optimization. The Bosch Rexroth MSK076C-0450-NN-M1-UG1-NNNN fits modular racks via its rotatable power connector, enabling natural convection cooling that dissipates heat effectively in enclosed or vibration-prone enclosures, sidestepping the bulk of forced-air alternatives. For retrofits in IndraDrive ecosystems, it aligns without encoder adapters, trimming custom tuning while amplifying signal integrity against electrical transients. In environments demanding continuous uptime, its overload capacity up to 5.2 times rated torque prevents stall-outs during peaks, allowing seamless scaling from prototype to full lines. By focusing on torque density and absolute encoding, the Bosch Rexroth MSK076C-0450-NN-M1-UG1-NNNN strengthens system stability, letting you achieve sub-millisecond synchronization and reduced variance that directly lifts throughput in rigorous industrial automation pipelines, all without inflating footprint or complexity.

When scouting actuators for velocity-sensitive architectures, the Bosch Rexroth MSK076C-0450-NN-M1-UG1-NNNN distinguishes itself through its balanced power profile, offering the precision and resilience that elevates performance in EMI-challenged or space-limited deployments.

The Bosch Rexroth MSK076C-0450-NN-M1-UG1-NNNN performs as a compact AC synchronous servo motor in the IndraDyn S MSK series, embedded at the drive interface in your motion stack. It translates pulse commands from IndraDrive controllers into rotational energy via electronic commutation, yielding 43.5 Nm standstill torque at 3.7 A continuous current, with peak speeds reaching 5000 rpm for agile start-stop profiles. The integrated optical Hiperface encoder delivers multiturn absolute feedback, relaying 128 sin/cos cycles per revolution for high-resolution tracking that feeds into PLCs or safety PLCs over EnDat-compatible buses, supporting synchronized multi-axis operations without homing routines.

Flange-mounted to a 125 mm frame, it couples to loads through a plain shaft with sealing ring, drawing from a shared DC link for regenerative efficiency in deceleration phases. Its surface-cooled windings maintain thermal stability up to 40°C ambient, with diagnostics monitoring rotor temperature and commutation angle to preempt faults, enabling redundancy via parallel cabling in critical nodes. In a layered system, the Bosch Rexroth MSK076C-0450-NN-M1-UG1-NNNN executes downstream from velocity planners but upstream of mechanical linkages, interfacing via the rotatable 240° plug for flexible routing in backplanes or cabinets—its IP65 sealing guards against ingress while relaying health metrics to HMIs, crafting a durable I/O pathway that evolves with protocols like Profinet or EtherCAT for uninterrupted data cycles.

Incorporating the Bosch Rexroth MSK076C-0450-NN-M1-UG1-NNNN injects a level of torque fidelity that holds firm at 43.5 Nm across wide speed bands, quelling the fluctuations that trigger overcurrents or positioning hunts in dynamic sequences, which in turn stabilizes cycle times and curbs energy spikes from inefficient braking. This reliability cascades into fewer quality escapes, as the absolute encoder’s granularity ensures trajectories track within arcseconds, empowering finer path planning without auxiliary sensors that add weight or points of failure.

Encoder-embedded parameters further optimize upkeep, storing calibration curves for drive auto-tuning that shortens commissioning and lets field teams interrogate faults remotely, often resolving issues in under 30 minutes versus hours for non-absolute systems. Its plug-oriented design eases engineering during panel layouts—rotating the connection avoids cable strain in awkward mounts, streamlining expansions and reallocating design hours from mechanical tweaks to software logic. Built to weather industrial rigors, this motor secures long-term performance with a 25-minute thermal constant that buffers against overloads, recycling kinetic energy to offset power draws and sustaining your automation’s edge through phased upgrades or load variants.

In wire and cable extrusion lines, the Bosch Rexroth MSK076C-0450-NN-M1-UG1-NNNN actuates capstan drives, where its peak torque manages pull variations in heated, dusty conditions, preserving critical system uptime for uniform gauging in continuous process control.

Electronics pick-and-place stations harness it for XY gantry motion, delivering fast data cycles from the Hiperface encoder to hit micron placements amid cleanroom constraints and rapid indexing, amplifying throughput in high-reliability assembly.

For printing presses in packaging, this servo motor synchronizes roller trains, meeting vibration and ink-mist challenges with absolute feedback that locks web alignment, supporting extended runs in modular automation environments.

When readying the Bosch Rexroth MSK076C-0450-NN-M1-UG1-NNNN for deployment, align the 125 mm flange’s pilot diameter to 0.02 mm tolerance and check shaft parallelism under 0.01 mm/100 mm to forestall vibration harmonics from day one. Confirm IndraDrive firmware supports Hiperface DSL 2.1 for full multiturn access, and position the motor so convection paths remain unobstructed—aim for 100 mm clearance above in cabinets, adding fins if ambient nears 40°C. Shield feedback cables with ferrite clamps every 1 m to damp EMI from nearby inverters, especially in dense racks.

Keep it primed with quarterly seal checks for lubricant weep in greasy atmospheres, gently cleaning the shaft collar with non-abrasive wipes to uphold IP65 barriers. Query encoder diagnostics via IndraWorks monthly to baseline commutation offsets and thermal profiles, spotting asymmetries that hint at winding fatigue. An annual torque-velocity sweep under no-load verifies the 5000 rpm ceiling holds, and though sealed-for-life bearings need no regrease, logging install torque aids lifecycle forecasting. This disciplined flow integrates with your PM schedule, nipping degradations early to safeguard motion fidelity.
