Applications and Use Cases

The 8LSC55.ee022ffgg-4 is ideal for a wide range of industrial applications, including packaging machinery, material handling, and robotics. Its compact design and reduced weight make it easy to integrate into space-constrained systems. Furthermore, the motor's excellent dynamic characteristics ensure precise positioning in high-speed processes. For example, in a pick-and-place application, the motor's high maximum torque (60.0 Nm) enables rapid acceleration and deceleration, improving cycle times. Additionally, the optional single-cable solution simplifies wiring, reducing installation time and potential points of failure.

Installation and Setup

Proper installation is crucial for optimal performance. The 8LSC55.ee022ffgg-4 supports mounting per EN 60034-7 (IM 3001, IM 3011, IM 3031). The flange conforms to DIN 42948 Form A, and the shaft end meets DIN 748 Form E. Ensure the motor is mounted on a stable surface to minimize vibration. For electrical connections, use the built-in plug-in connectors. The recommended servo drive is the ACOPOS 017X, which ensures seamless integration. Always follow the manufacturer's manual for wiring and configuration to avoid damage.

Maintenance and Reliability

Routine maintenance helps extend the service life of the 8LSC55.ee022ffgg-4. The motor is externally fan-cooled (IC4A0A6), and the fan module is replaceable. Inspect the fan periodically for dust accumulation and ensure it operates freely. The motor features thermal protection via KTY83-110 or AM-PTC1000 sensors, with a maximum winding temperature of 155°C. Operating temperature range is -15 to +40°C (max +55°C with derating). The motor has an IP64 protection rating per EN 60034-5, and the fan is IP20 (or IP65 with optional oil seal). For applications with high humidity, ensure the environment stays within the specified limits (max 90% non-condensing). Regular inspection per the manufacturer's safety manual is recommended.

Compatibility and Integration

The 8LSC55.ee022ffgg-4 is designed to work with B&R ACOPOS servo drives, specifically the 017X model. This combination ensures optimal performance and reliability. The motor supports resolver (R0/R2) or EnDat feedback systems, including safety-related variants. The single-cable (hybrid) solution reduces cabling complexity. For functional safety, encoders are available, and STO (Safe Torque Off) is implemented via the ACOPOS drive. Always verify compatibility with your existing control system before ordering.
