Description

The Bosch Rexroth R911307234, also designated as MSK060C-0300-NN-M2-UG0, is a high-performance permanent magnet AC servo motor from the renowned MSK series, engineered for dynamic motion control applications requiring precision, reliability, and compact integration. As part of Bosch Rexroth’s comprehensive drive technology portfolio, this motor is designed to pair seamlessly with IndraDrive amplifiers—especially the IndraDrive Cs and IndraDrive Mi families—enabling high-bandwidth torque and speed control in demanding automation environments. The Bosch Rexroth R911307234 delivers continuous torque of 2.5 Nm at 3000 rpm, with a peak torque capability of up to 7.5 Nm, making it ideal for applications ranging from robotic arms and pick-and-place systems to printing presses and semiconductor handling equipment.

Built with a low-inertia rotor and optimized magnetic circuit, the MSK060C-0300-NN-M2-UG0 ensures rapid acceleration and smooth operation even at low speeds, minimizing cogging and torque ripple. Its robust construction features an IP65-rated housing for protection against dust and water jets, oil-sealed bearings for extended service life in contaminated environments, and an integrated resolver or encoder (depending on variant) for precise position feedback. The Bosch Rexroth R911307234 uses the standardized M2 mounting flange per IEC 60034-5, ensuring mechanical compatibility with a wide range of gearboxes and couplings. With its UG0 cable configuration—featuring a pre-assembled, shielded motor power and feedback cable—the MSK060C-0300-NN-M2-UG0 simplifies installation and reduces wiring errors in high-density machine layouts.

Technical Specifications

Main Features and Advantages

High dynamic response with low inertia design:
The Bosch Rexroth R911307234 features a lightweight rotor and compact stator geometry that minimizes rotational inertia, enabling sub-millisecond response times in torque control mode. This allows machines to achieve higher throughput without sacrificing positioning accuracy—critical in high-speed packaging lines or delta robots where cycle time is king.

Robust construction for industrial longevity:
Encased in a corrosion-resistant aluminum housing with double-shielded, grease-lubricated bearings, the MSK060C-0300-NN-M2-UG0 withstands continuous exposure to coolant mist, metal chips, and ambient humidity. The oil seal on the drive-end bearing prevents lubricant migration and contamination ingress, extending maintenance intervals beyond 20,000 operating hours under normal conditions.

Seamless integration with IndraDrive ecosystem:
Thanks to Rexroth’s standardized motor-amplifier interface, the Bosch Rexroth R911307234 automatically communicates its parameter set (torque constant, thermal model, feedback type) to compatible IndraDrive units via the power connector—eliminating manual tuning or DIP switch configuration. This “plug-and-play” capability reduces commissioning time by up to 50% and ensures optimal performance out of the box.

Integrated high-resolution feedback for precision motion:
The built-in 2048-line incremental encoder provides quadrature signals (A/B/Z) with index pulse, supporting position resolution down to 0.044° mechanical when used with a standard 25-bit interpolation drive. This level of fidelity enables contouring accuracy in CNC axes and jitter-free velocity control in web handling systems. The encoder is fully sealed and shock-rated to 100 g, ensuring reliability in high-vibration environments.

Simplified installation with UG0 hybrid cable:
Unlike motors requiring separate power and feedback cables, the MSK060C-0300-NN-M2-UG0 ships with a single UG0 hybrid cable that combines all conductors in one shielded jacket, terminated with matching connectors for IndraDrive. This reduces panel space, minimizes EMI coupling, and accelerates field wiring—especially valuable in OEM production where assembly time directly impacts cost.

Application Field

The Bosch Rexroth R911307234 is extensively deployed in industries where precision, speed, and reliability converge. In the packaging sector, it powers horizontal form-fill-seal (HFFS) machines, carton erectors, and labeling heads—executing synchronized motions at rates exceeding 200 cycles per minute. Its low cogging ensures consistent film tension, while high peak torque handles sudden load changes during product insertion.

In machine tooling, the MSK060C-0300-NN-M2-UG0 drives rotary tables, tool changers, and feed axes on compact CNC mills and lathes. The motor’s thermal stability and minimal heat generation prevent thermal drift during long machining runs, maintaining micron-level tolerances. Similarly, in electronics manufacturing, it positions PCBs, solder paste stencils, and component pick-up heads with repeatability better than ±0.01 mm.

Material handling systems—such as automated guided vehicles (AGVs), palletizers, and gantry robots—also benefit from the Bosch Rexroth R911307234’s high power density and ruggedness. Its IP65 rating allows operation in washdown areas of food processing plants, while the oil-sealed bearings tolerate airborne flour, sugar, or starch without premature wear. Even in renewable energy, the MSK060C-0300-NN-M2-UG0 controls solar tracker azimuth drives and battery module assembly robots, proving its versatility across emerging automation frontiers.

Installation and Maintenance

Pre-installation preparation: Before mounting the Bosch Rexroth R911307234, verify shaft alignment and coupling tolerance—misalignment beyond 0.05 mm can cause bearing overload and premature failure. Use only Rexroth-specified torque values for the M2 flange bolts (typically 5.5 N·m in a cross-pattern sequence). Ensure the UG0 cable routing avoids sharp bends (min. bend radius: 75 mm) and is secured away from high-frequency sources like VFDs or welding equipment to prevent encoder noise. Confirm that the connected IndraDrive firmware supports the MSK060C motor ID; older versions may require a parameter update.

Maintenance recommendations: The MSK060C-0300-NN-M2-UG0 is maintenance-free under normal operating conditions due to its lifetime-lubricated bearings. However, inspect the motor housing annually for signs of coolant ingress, paint blistering, or excessive surface temperature (>80°C indicates possible overload or poor ventilation). Check cable strain relief and connector integrity—loose pins can cause intermittent faults that mimic drive errors. If the motor is used in a vertical orientation, consider upgrading to a brake version to prevent uncontrolled backdriving during power loss.
