6. Selection Recommendations
When selecting the R911317019, consider the following:
- 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.
