High-Speed Precision: The B&R 8LSC45.ee060ff00-4 Servo Motor
In modern manufacturing, the demand for faster cycle times and higher precision continues to grow. The B&R 8LSC45.ee060ff00-4 three-phase synchronous servo motor addresses these needs with a nominal speed of 6000 rpm and a nominal torque of 6.5 Nm. This motor is designed for applications requiring excellent dynamic characteristics and positioning accuracy, making it a valuable component in advanced automation systems.
With a compact and lightweight design, the 8LSC45.ee060ff00-4 helps reduce machine footprint and energy consumption. Its permanent-magnet, electronically commutated construction ensures efficient operation, while the large overload capacity provides flexibility for demanding tasks. For engineers seeking a balance of performance and cost, this motor offers a compelling solution.
Technical Specifications and Performance Analysis
The 8LSC45.ee060ff00-4 delivers robust performance metrics that translate directly to operational efficiency. The nominal power of 4096 W and nominal current of 8.0 A indicate a motor capable of sustained high-output work. The stall torque of 10.4 Nm and stall current of 12.8 A provide a strong starting point for applications requiring high initial force.
Key electrical parameters further define its capability. The torque constant of 0.81 Nm/A ensures predictable torque output relative to current, while the voltage constant of 49.22 V/1000 rpm helps in precise speed control. The stator resistance of 0.69 Ohm and stator inductance of 5.4 mH contribute to the motor's electrical time constant of 7.8 ms, enabling rapid response to control signals.
Mechanically, the motor features a moment of inertia of 3.2 kg·cm² and a mass of 7.74 kg without brake. The optional brake provides a holding torque of 8 Nm, adding safety in vertical applications. The thermal time constant of 26 minutes allows for sustained operation under load, while the maximum speed of 6600 rpm offers headroom for high-speed processes.
Cost-Efficiency Through Design and Integration
The 8LSC45.ee060ff00-4 is engineered to reduce total cost of ownership. Its high nominal speed of 6000 rpm allows for direct drive applications, eliminating the need for gearboxes in many cases. This reduces component costs and maintenance requirements, while improving overall system efficiency.
The single-cable (hybrid) solution option simplifies wiring and reduces installation time. By combining power and feedback in one cable, this design lowers material costs and minimizes potential connection points, enhancing reliability. For system integrators, this translates to faster commissioning and reduced labor expenses.
Furthermore, the motor's large overload capacity (maximum torque of 30.4 Nm) means it can handle peak demands without oversizing, avoiding unnecessary capital expenditure. The optimized torque rippling ensures smooth operation, which can improve product quality and reduce waste in processes like cutting or forming.
Applications in Modern Manufacturing
The 8LSC45.ee060ff00-4 is well-suited for a variety of industrial applications. In packaging machinery, its high speed and precision enable rapid, accurate product placement. The motor's compact size allows for space-saving machine designs, which is critical in facilities with limited floor space.
In electronics assembly, the motor's excellent dynamic characteristics support fast, precise movements for component placement. The availability of encoders for functional safety enhances operator protection, aligning with modern safety standards. Additionally, the externally fan-cooled design (IC4A0A6) ensures reliable operation in continuous-duty applications.
For material handling systems, the 8LSC45.ee060ff00-4 provides the torque and speed needed for efficient conveyor control. The optional brake (8 Nm holding torque) ensures secure stopping, preventing load drift. These features make the motor a versatile choice for diverse automation needs.
Compatibility and System Integration
The 8LSC45.ee060ff00-4 is designed to work seamlessly with B&R's ACOPOS servo drives, specifically the recommended 017X series. This integration ensures optimal performance and simplifies parameter setup. The motor supports both resolver and EnDat feedback systems, including safety-related variants, providing flexibility for different control architectures.
With a cable cross-section of 1.5 mm² and a connector size of 1, the motor is easy to wire into existing systems. The IP64 protection rating (per EN 60034-5) makes it suitable for most industrial environments, while the optional oil seal can upgrade protection to IP65. This compatibility reduces engineering effort and accelerates project timelines.
Real-World Application Example
In a typical high-speed labeling application, the 8LSC45.ee060ff00-4 can maintain precise label placement at rates exceeding 300 products per minute. Its high nominal speed and low inertia enable rapid acceleration and deceleration, minimizing cycle time. The motor's torque stability ensures consistent label tension, reducing waste and rework.
This hypothetical scenario illustrates how the motor's specifications translate into tangible productivity gains. By choosing a motor that matches the application's demands, manufacturers can avoid over-engineering and achieve optimal cost efficiency.
Frequently Asked Questions
