8LSC57.ee022ffgg-4 | B&R 8.25 kW Servo Motor

Introduction to the B&R 8LSC57.ee022ffgg-4

When your application demands precise motion control and high dynamic performance, the 8LSC57.ee022ffgg-4 from B&R stands ready. This three-phase synchronous servo motor is engineered for excellent positioning accuracy and compact size, making it a reliable choice for modern industrial automation.

With a nominal power of 8250 W and a nominal torque of 35.8 Nm, this motor handles heavy workloads while maintaining efficiency. Its permanent-magnet design and electronic commutation ensure smooth operation and reduced torque ripple, which translates into better controllability in your processes.

Key Features and Technical Specifications

The 8LSC57.ee022ffgg-4 offers a robust set of parameters that support a wide range of motion control tasks. Here are the core specifications you can rely on:

• Nominal speed: 2200 rpm
• Number of pole pairs: 5
• Nominal torque: 35.8 Nm
• Nominal power: 8250 W
• Nominal current: 16.2 A
• Stall torque: 37.7 Nm
• Stall current: 17.0 A
• Maximum torque: 90.0 Nm
• Maximum current: 55.6 A
• Maximum speed: 5000 rpm

One standout feature is the high overload capacity. With a maximum torque of 90.0 Nm, this motor can handle short bursts of heavy load without compromising performance. This capability is essential for applications that experience sudden load spikes or require rapid acceleration.

Additionally, the motor includes a built-in holding brake with a torque of 27 Nm, ensuring safe operation when the motor is stationary. This brake adds reliability to vertical axes or any application where holding position is critical.

Applications and Use Cases

Because of its excellent dynamic characteristics, the 8LSC57.ee022ffgg-4 is well-suited for a variety of industrial applications. You will find it in packaging machinery, material handling systems, and robotic cells where precise positioning and repeatability are paramount.

Furthermore, its compact design and reduced weight make it an ideal choice for mobile or space-constrained equipment. The motor's ability to deliver high torque in a small footprint helps engineers optimize machine layouts without sacrificing performance.

In addition, the optional single-cable (hybrid) solution simplifies wiring and reduces installation time, which is a significant advantage in complex multi-axis systems.

Installation and Setup

Proper installation is key to getting the most out of your 8LSC57.ee022ffgg-4. The motor supports multiple mounting configurations per EN 60034-7, including IM 3001 horizontal and IM 3011/3031 orientations. This flexibility allows you to integrate it into your machine with ease.

The shaft end conforms to DIN 748 Form E, and the flange follows DIN 42948 Form A, ensuring compatibility with standard couplings and gearboxes. Always refer to the B&R manual for detailed mounting instructions and torque specifications for fasteners.

For electrical connections, the motor uses a connector size/type 1, and the recommended servo drive is the ACOPOS 024X. This pairing ensures optimal performance and simplifies commissioning.

Maintenance and Reliability

Reliability is a key concern in industrial environments, and the 8LSC57.ee022ffgg-4 is built to last. The motor is rated for continuous operation (S1) per EN 60034-1, and its insulation class F (per IEC 60085) allows for a maximum winding temperature of 155°C, providing a safety margin under normal operating conditions.

To maintain long-term performance, follow a routine inspection schedule. Check for any unusual noise or vibration, and ensure that the cooling fan (externally fan-cooled, IC4A0A6) is free from dust and debris. The motor's IP64 protection rating (with optional IP65 with oil seal) guards against dust and water ingress, but regular cleaning of the fan area is still recommended.

Additionally, the motor features thermal protection via KTY83-110 or AM-PTC1000 sensors, which help prevent overheating. By monitoring these signals through your drive system, you can avoid unexpected downtime and extend the motor's service life.

Compatibility and Integration

The 8LSC57.ee022ffgg-4 is designed to work seamlessly with B&R's ACOPOS servo drives, specifically the 024X model. This combination provides a complete motion control solution with high performance and easy setup.

The motor supports both resolver and EnDat feedback systems, including safety-related variants. This flexibility allows you to choose the feedback type that best matches your safety requirements and control architecture.

Furthermore, the optional single-cable (hybrid) solution reduces cabling complexity, which is especially beneficial in applications with many axes. This integration simplifies maintenance and reduces the risk of wiring errors.
