High-Speed Precision: The B&R 8LSC47.ee060ffgg-4 in Modern Automation
In today's fast-paced manufacturing environment, the demand for precise, high-speed motion control continues to grow. The B&R 8LSC47.ee060ffgg-4 three-phase synchronous servo motor is engineered to meet these challenges, offering a blend of dynamic performance and compact design. This motor is part of the 8LSC series, known for its excellent dynamic characteristics and positioning precision.
With a nominal speed of 6000 rpm and a maximum speed of 6600 rpm, this motor is well-suited for applications requiring rapid acceleration and deceleration. Its permanent-magnet, electronically commutated design ensures efficient operation and reduced weight, making it an ideal choice for modern machinery where space and performance are critical.
Key Technical Specifications and Performance
The 8LSC47.ee060ffgg-4 delivers robust performance metrics that cater to demanding industrial applications. It provides a nominal torque of 9.1 Nm and a stall torque of 15.6 Nm, ensuring strong holding and driving capabilities. The motor's maximum torque reaches 45.6 Nm, allowing it to handle peak loads during operation.
Electrical characteristics include a nominal current of 11.2 A and a stall current of 19.3 A, with a maximum current of 88.0 A. The torque constant is 0.81 Nm/A, and the voltage constant is 49.22 V/1000 rpm. These parameters indicate efficient torque generation relative to current draw, contributing to the motor's overall energy efficiency.
The motor features a stator resistance of 0.41 Ohm and a stator inductance of 3.5 mH, with an electrical time constant of 8.5 ms. The thermal time constant is 27 minutes, and the moment of inertia is 4.8 kg·cm². The motor mass is 9.55 kg without brake, and the optional brake adds 1.00 kg with a holding torque of 15 Nm.
Designed for Dynamic Applications
The 8LSC47.ee060ffgg-4 is designed for applications that require excellent dynamic characteristics and positioning precision. Its large overload capacity and optimized torque rippling ensure good controllability, making it suitable for high-performance motion control tasks. The motor's compact size and reduced weight facilitate integration into space-constrained machinery.
Typical applications include packaging machinery, textile equipment, and material handling systems. In a packaging line, for example, the motor's high speed and precise positioning enable accurate cutting and sealing operations. In material handling, its dynamic response supports rapid pick-and-place actions, improving throughput.
Flexible Feedback and Safety Options
The motor supports both resolver and EnDat feedback systems, including safety-related variants. This flexibility allows integration with various control architectures. The single-cable (hybrid) solution option simplifies wiring and reduces installation time, which is a significant advantage in complex machinery.
For functional safety, encoders are available, and safe torque off (STO) is implemented via the ACOPOS servo drive. This integration ensures that safety requirements can be met without additional components, streamlining system design.
Compatibility and Integration
The recommended servo drive for the 8LSC47.ee060ffgg-4 is the ACOPOS 024X. This drive is designed to match the motor's performance characteristics, ensuring optimal operation. The motor's feedback options are compatible with ACOPOS drives, providing a seamless integration experience.
For applications requiring higher sustained current, a larger ACOPOS class (e.g., 034X) may be considered, as the 024X's nominal current rating of 80 A is below the motor's peak current of 88.0 A. This boundary is important for system designers to consider when planning for continuous high-load operations.
Comparison with Similar Servo Motors
When compared to other servo motors in its class, the 8LSC47.ee060ffgg-4 stands out due to its high nominal speed of 6000 rpm and a power-to-weight ratio that is favorable for dynamic applications. Its torque constant of 0.81 Nm/A indicates efficient torque production per ampere, which can translate to lower energy consumption.
In contrast, some competing motors may offer lower maximum speeds or require larger frame sizes to achieve similar torque. The 8LSC47.ee060ffgg-4's compact design and reduced weight provide an advantage in applications where space is at a premium.
