Why the 8LSC47.ee060ff00-4 Excels in High-Speed Automation
When your application demands rapid acceleration, precise positioning, and compact design, the B&R 8LSC47.ee060ff00-4 three-phase synchronous servo motor stands out. This externally fan-cooled, permanent-magnet motor is engineered for dynamic performance, making it a top choice for modern manufacturing lines. Its high nominal speed of 6000 rpm and maximum speed of 6600 rpm enable fast cycle times, directly boosting throughput.
Beyond speed, the motor delivers a nominal torque of 9.1 Nm and a stall torque of 15.6 Nm, ensuring robust force even at standstill. With a torque constant of 0.81 Nm/A, it converts electrical current into mechanical force efficiently. For engineers, this translates to reliable, repeatable motion control in applications like packaging, material handling, and precision assembly.

The motor's high overload capacity—maximum torque of 45.6 Nm—allows it to handle short-duration peak loads without compromising performance. This is particularly valuable in applications with intermittent high-force demands, such as stamping or cutting operations.
Real-World Applications: Where Precision Meets Speed
In a typical packaging line, the 8LSC47.ee060ff00-4 drives servo-controlled cutters and film feeders. Its 6000 rpm nominal speed enables rapid indexing, while the 5 pole pairs provide smooth, low-ripple torque for consistent cut lengths. The motor's compact size and reduced weight simplify machine design, freeing up space for other components.
For material handling systems, the motor's high stall torque (15.6 Nm) ensures reliable holding of loads at standstill, preventing drift. The optional single-cable hybrid solution reduces wiring complexity, cutting installation time and potential failure points. Additionally, encoders with functional safety support enable safe motion monitoring, meeting stringent safety requirements.
In precision assembly, the motor's excellent dynamic characteristics and positioning accuracy are critical. The low moment of inertia (4.8 kg·cm²) allows rapid start-stop cycles, while the optimized torque ripple ensures smooth, precise movements—essential for tasks like screwdriving or component placement.
Integration with ACOPOS Drives: A Seamless Pair
The 8LSC47.ee060ff00-4 is designed to work seamlessly with B&R ACOPOS servo drives. The recommended drive, ACOPOS 024X, provides the necessary current and control for optimal performance. However, note that the 024X has a nominal current rating of 80 A, which is below the motor's peak current of 88.0 A. This means the 024X can handle the peak current only within its short-duration overload window. For sustained high-current demands, consider a higher ACOPOS class, such as the 034X.
The motor supports both resolver and EnDat feedback systems, including safety-related variants. This flexibility allows integration with various control architectures, from simple speed control to advanced position control with functional safety. The built-in plug-in connectors and optional single-cable solution simplify installation and maintenance.
Environmental and Mounting Considerations
The motor operates reliably in temperatures from -15°C to +40°C, with a maximum of +55°C, and can be derated at higher altitudes. It is rated IP64 per EN 60034-5, with the fan rated IP20 (IP65 with optional oil seal). This makes it suitable for most industrial environments, though additional protection may be needed in dusty or wet conditions.
Mounting options include IM 3001 (horizontal), IM 3011, and IM 3031, per EN 60034-7. The flange conforms to DIN 42948 Form A, and the shaft end to DIN 748 Form E, ensuring compatibility with standard gearboxes and couplings. The motor's vibration severity is A1 per EN 60034-14, indicating low vibration levels for stable operation.
Frequently Asked Questions
