Installation & Setup Guidance
Proper installation is critical for optimal performance of the 8LSC45.ee060ff00-4. Follow these guidelines:
- Mount the motor according to EN 60034-7 (IM) configurations: IM 3001 horizontal, IM 3011, or IM 3031. Ensure the flange matches DIN 42948 Form A and the shaft end conforms to DIN 748 Form E.
- Use the recommended ACOPOS servo drive (type 017X) to ensure correct electrical matching and control performance.
- Connect the motor cable with a cross-section of 1.5 mm², as specified. Verify the connector size/type matches the motor's built-in plug-in connectors.
- If using the optional brake, ensure the holding torque of 8 Nm meets your application's safety requirements.
- For environments with high ambient temperatures, apply derating: 10% per 10 K above 40°C and 5% per 1000 m elevation increase.
Maintenance & Reliability
To maximize the service life of the 8LSC45.ee060ff00-4, implement a routine maintenance schedule:
- Periodically inspect the external fan for dust accumulation and ensure unobstructed airflow. The fan is rated IP20, so keep the area clean.
- Check the motor's thermal protection (KTY83-110 / AM-PTC1000) by monitoring winding temperature. The maximum winding temperature is 155°C, but for extended life, keep it below 130°C when using ACOPOS with EnDat/resolver.
- Verify that the motor's IP64 protection is maintained. If an oil seal is installed, inspect it for wear.
- Listen for unusual noise from the fan. The 24 VDC fan for this size is rated at 57 dB(A), and the 230 VAC fan at 37 dB(A). A significant increase may indicate bearing wear.
- Check the shaft for excessive runout or vibration, which could indicate bearing issues.
By following these steps, you can reduce downtime and extend the operational life of your equipment.
Selection Guide & Purchasing Advice
Before purchasing the B&R 8LSC45.ee060ff00-4, verify that it matches your application requirements. Consider the following:
- Confirm the required torque and speed profiles. The motor provides 6.5 Nm nominal torque and 6000 rpm nominal speed, with a maximum speed of 6600 rpm.
- Check the compatibility with your existing servo drive. The recommended ACOPOS drive is model 017X. Ensure your control system supports the selected feedback type (resolver or EnDat).
- Evaluate the need for the optional brake. The motor's brake has a holding torque of 8 Nm and adds 1.0 kg to the mass.
- Assess the environmental conditions. The motor operates in -15°C to +40°C (up to +55°C with derating) and is rated IP64. For higher elevations, note that the maximum is 2000 m.
