High-Speed Precision in Modern Automation
In today's fast-paced manufacturing environment, achieving high throughput while maintaining precise positioning is a constant challenge. The B&R 8LSC46.ee060ff00-4 three-phase synchronous servo motor addresses this need with a nominal speed of 6000 rpm and a maximum speed of 6600 rpm. This motor is engineered for applications that demand excellent dynamic characteristics and positioning precision, all within a compact and lightweight design.
As part of the 8LSC series, this motor is externally fan-cooled and features a permanent-magnet, electronically commutated design. It offers a large overload capacity and optimized torque rippling for good controllability, making it a reliable choice for demanding industrial tasks. The motor's design also supports a single-cable (hybrid) solution option, simplifying installation and reducing wiring complexity.
Key Technical Specifications of the 8LSC46.ee060ff00-4
The 8LSC46.ee060ff00-4 delivers robust performance metrics that cater to high-speed, high-precision applications. With a nominal torque of 7.7 Nm and a stall torque of 13.0 Nm, it provides ample force for a variety of motion control tasks. The motor's nominal power is 4807 W, and it operates with a nominal current of 9.4 A, while the stall current is 16.0 A.
For applications requiring short bursts of high force, the motor can deliver a maximum torque of 38.0 Nm with a maximum current of 72.9 A. The torque constant is 0.81 Nm/A, and the voltage constant is 49.22 V/1000 rpm. These parameters ensure efficient conversion of electrical energy into mechanical motion, contributing to the motor's overall performance and reliability.
Additional electrical characteristics include a stator resistance of 0.53 Ohm and a stator inductance of 4.3 mH. The electrical time constant is 8.0 ms, and the thermal time constant is 27 minutes. The motor has a moment of inertia of 4.0 kg·cm² and a mass of 8.64 kg (without brake). For applications requiring holding torque, an optional brake provides 15 Nm of holding torque, adding 1.00 kg to the mass and 1.66 kg·cm² to the inertia.
Built for Demanding Applications
The 8LSC46.ee060ff00-4 is well-suited for a range of industrial applications, including packaging machinery, material handling, and robotics. In a typical packaging line, the motor's high speed and precise positioning enable rapid and accurate product placement, reducing cycle times and increasing throughput. Its compact size and reduced weight make it easy to integrate into space-constrained equipment.
In material handling systems, the motor's large overload capacity ensures reliable operation even under variable loads. The optimized torque rippling contributes to smooth motion, which is critical for applications requiring high surface quality or precise alignment. The motor's IP64 protection rating (per EN 60034-5) makes it suitable for environments with dust and water splashes, while the externally fan-cooled design (IC4A0A6) maintains performance under continuous operation.
Compatibility and Integration
The 8LSC46.ee060ff00-4 is designed to work seamlessly with B&R's ACOPOS servo drives, specifically the recommended drive model 024X. This integration ensures optimal performance and simplifies system setup. The motor supports both resolver and EnDat feedback systems, including safety-related variants, providing flexibility for various control architectures.
For enhanced safety, the motor can be equipped with encoders for functional safety, and the Safe Torque Off (STO) function is implemented via the ACOPOS servo drive. The motor also offers a single-cable (hybrid) solution option, which combines power and feedback signals into one cable, reducing installation time and potential points of failure.
Environmental and Mounting Considerations
The motor operates in a temperature range of -15 to +40 degrees Celsius, with a maximum of +55 degrees Celsius, and requires derating above 40 degrees Celsius (10% per 10 K). It can operate at elevations up to 2000 meters, with a derating of 5% per 1000 meters above that. The maximum flange temperature is 65 degrees Celsius, and the motor is rated IP64 per EN 60034-5, with the fan rated IP20.
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 meets DIN 748 Form E. The motor's vibration severity is A1 per EN 60034-14, and the bearing life is calculated per DIN ISO 281. The coating is water-based RAL 9005, providing a durable finish.
