Bosch Rexroth MSK040C-0600-NN-M1-UG1-NNNN – High‑Torque IndraDyn S Servo Motor for Compact, Fast Axes

The Rexroth IndraDyn S MSK040C-0600-NN-M1-UG1-NNNN is a compact, high-torque synchronous servo motor built for precise positioning and fast cycling on small to mid-size axes. One thing I appreciate is how the MSK040 frame delivers surprisingly strong continuous torque without ballooning the footprint—ideal when you’re squeezing performance into an existing machine base. In many cases, this configuration is supplied without a holding brake (code “NN”) and with a keyed shaft (M1), pairing cleanly with IndraDrive systems for smooth, low-cogging motion.

Key Features

• High torque density – The MSK040 frame typically delivers strong continuous torque relative to its size, great for tight machine layouts.
• Smooth, precise motion – Low cogging design and high-resolution feedback help achieve stable velocity and crisp positioning.
• Encoder integrated – Variant-dependent digital feedback compatible with Rexroth IndraDrive; ideal for synchronized multi-axis lines.
• Robust construction – Industrial-grade sealing and bearings for 24/7 duty in packaging, assembly, and light machining environments.
• Flexible connectors – Motor-side power and feedback connectors oriented per the “UG1” option for easier cable routing in compact cabinets.
• Surface cooling – Natural convection/surface-cooled operation; no external fan needed in most use cases.

Operating Temperature	Typically 0…+40 °C ambient for rated data (application-dependent)
Feedback / I/O	High‑resolution encoder (variant-dependent); integrated thermal sensor; separate power and feedback connectors
Brake	Code “NN” typically indicates no holding brake (verify against motor nameplate)
Communication Interfaces	Encoder protocol as specified by the variant (e.g., Rexroth-compatible digital feedback via IndraDrive)
Installation Method	Flange mount to machine frame; connect to IndraDrive power/feedback cables per Rexroth wiring standards

Application Fields

From my experience, the MSK040C format fits best where small inertia and quick acceleration matter more than raw horsepower. Typical roles include:

• Pick-and-place and SCARA axes in electronics or medical device assembly
• Packaging machinery: film feed, sealing jaws, rotary knives, small unwind/rewind stations
• Light-duty indexing tables and feeders in printing and labeling
• Auxiliary axes on compact CNC, grinding, or EDM handling modules

One packaging client told me they swapped in this MSK040C variant and shaved roughly 12–15% off cycle time without changing their gearbox, simply due to the motor’s torque-to-inertia balance.

Advantages & Value (Procurement View)

• Reliability under duty – MSK series motors are built for continuous operation; fewer unplanned stops typically means lower cost of downtime.
• Rexroth ecosystem compatibility – Smooth plug-in with IndraDrive (cables, parameter sets, safety options), reducing commissioning effort.
• Lifecycle support – Global spare parts and service; firmware and parameter tools widely available to maintenance teams.
• Cost control – Compact footprint can avoid mechanical redesign; in many cases you can reuse mounts and couplings thanks to the standardized flange and shaft.

Installation & Maintenance

• Mounting – Rigidly flange-mount to a flat, vibration-damped surface. Align shaft carefully; avoid side loads beyond spec.
• Wiring – Use Rexroth-approved power and encoder cables; maintain proper shielding and grounding to limit EMI. Route power and signal separately where possible.
• Environment – Provide free air around the housing for heat dissipation. Keep within typical 0…+40 °C ambient for rated performance.
• Safety – Lock-out/tag-out before servicing; discharge drive DC bus; verify connectors are fully seated and strain-relieved.
• Routine checks – Inspect connectors and seals, clean dust buildup on the housing, and monitor bearing noise. Update drive firmware/parameters when swapping encoders or windings.

Quality & Certifications

• CE compliant; UL/cUL recognition commonly available for MSK series
• RoHS-conform design in most current builds
• Manufacturer’s warranty typical for Rexroth motors; our sales warranty: 365 days

Compatible Supporting Components

• Rexroth IndraDrive units (e.g., HCS01/HCS02/HCS03 series) sized to the “0600” winding data
• Rexroth motor power and feedback cable sets for MSK motors (lengths as required by the installation)
• Precision couplings or planetary gearboxes sized for the MSK040 shaft and torque

If you share the exact nameplate or project duty (torque/speed, ambient, brake needed), I can match the winding “0600” and feedback option to a pre-validated IndraDrive sizing, so commissioning is straightforward.
