3. Advantages and Features

• High Reliability: Built with industrial-grade materials and tested for a mean time between failures (MTBF) exceeding 100,000 hours, the R911317019 ensures minimal downtime in 24/7 operations. Its robust design resists electromagnetic interference (EMI) and mechanical vibrations, making it suitable for noisy industrial environments.
• Precision Motion Control: The Hiperface® encoder enables high-resolution position tracking, critical for applications requiring sub-millimeter accuracy, such as semiconductor wafer handling or precision assembly.
• Energy Efficiency: The motor’s 95% efficiency rating reduces energy consumption, lowering operational costs by up to 20% compared to standard servo motors. This efficiency is achieved through optimized winding design and regenerative braking capabilities.
• Flexible Integration: Rotatable electrical connectors (240° adjustment) simplify installation in confined spaces, while support for multiple communication protocols ensures seamless integration with both Rexroth and third-party control systems.
• Compact Design: The 61 mm frame size allows for easy retrofitting in existing machinery or integration into new systems with space constraints, without compromising on performance.

4. Application Areas and Case Studies

Industry Applications

• Semiconductor Manufacturing: Used in wafer inspection and pick-and-place systems to achieve sub-micron positioning accuracy.
• Robotics: Powers collaborative robots (cobots) in electronics assembly for delicate component handling.
• Packaging: Ideal for high-speed labeling and sorting machines, ensuring consistent throughput and precision.
• CNC Machining: Enables rapid tool positioning and contouring in milling and turning processes.

Case Study

5. Competitor Comparison

• Superior Torque-to-Size Ratio: Delivers 15% higher continuous torque than comparable models in its power class, enabling more robust load handling in a compact form factor.
• Advanced Encoder Technology: The Hiperface® multi-turn encoder offers absolute positioning without reference homing, improving system efficiency compared to motors with incremental encoders.
• Enhanced Environmental Resistance: The IP65 rating provides better protection against dust and water compared to standard IP54-rated alternatives, expanding its suitability for harsh environments.
• Cost-Effective Operation: Lower energy consumption and extended maintenance intervals result in a 20% lower total cost of ownership over the motor’s lifespan.

6. Selection Recommendations

• Load Requirements: Ensure the motor’s continuous torque (2.7 N·m) and speed range (0–6,000 rpm) align with your application’s mechanical demands, especially for dynamic or high-inertia loads.
• Environmental Conditions: If operating in temperatures above 40°C or highly corrosive environments, consider optional coatings or forced cooling to maintain performance and longevity.
• Control System Compatibility: Verify that your drive system supports the Hiperface® encoder protocol and communication standards (e.g., Profinet, EtherCAT) for seamless integration.
• Budget and Performance Balance: While the motor offers premium precision and efficiency, assess whether its specifications match your project’s accuracy and speed requirements to avoid over-engineering.

7. Precautions

• Installation: Follow Rexroth’s guidelines for proper mounting to ensure mechanical alignment and secure fastening, reducing the risk of vibration-induced damage. Use torque wrenches to meet specified tightening values for mounting bolts.
• Electrical Safety: Always disconnect power before installing or servicing the motor. Use shielded cables for encoder and power connections to minimize EMI and ensure signal integrity, and ensure proper grounding to comply with electrical safety standards.
• Maintenance: Regularly inspect the motor for signs of wear, such as unusual noise or overheating. Clean external surfaces to prevent dust accumulation that may affect thermal performance, and lubricate bearings according to the manufacturer’s schedule (typically every 20,000 hours of operation).
• Firmware and Configuration: Use Rexroth’s official software to configure motor parameters and update firmware, ensuring compatibility with your control system and accessing the latest performance optimizations.
