Introduction to the 8LSC55.ee030ff00-4

When your application demands precise positioning and excellent dynamic response, the 8LSC55.ee030ff00-4 from B&R delivers. This three-phase synchronous servo motor is engineered for compactness and reduced weight, making it ideal for modern machinery. With a nominal torque of 22.4 Nm and a nominal speed of 3000 rpm, it balances power and control effectively.

Part of the 8LSC series, this motor uses permanent-magnet, electronically commutated technology. It offers a large overload capacity and optimized torque rippling for smooth, accurate motion. Whether you are upgrading an existing line or designing new equipment, this motor provides reliable performance in a space-saving package.

Key Features and Technical Specifications

The 8LSC55.ee030ff00-4 stands out with its robust electrical and mechanical parameters. Below are the core specifications that define its capability:

• Nominal torque: 22.4 Nm
• Nominal speed: 3000 rpm
• Maximum torque: 60.0 Nm
• Maximum speed: 5000 rpm
• Nominal power: 7043 W
• Stall torque: 27.3 Nm
• Moment of inertia: 12.9 kg·cm²
• Mass (without brake): 1.00 kg

One distinctive feature is the high overload capacity, allowing the motor to handle peak demands without compromising stability. Additionally, the single-cable (hybrid) solution option simplifies wiring and reduces installation time, which is a significant advantage in complex systems.

Applications and Use Cases

This servo motor excels in applications requiring precise speed and position control, such as packaging machinery, material handling, and robotic systems. Its compact size and low inertia enable rapid acceleration and deceleration, improving cycle times. Furthermore, the optional encoders for functional safety make it suitable for safety-critical processes where monitoring is essential.

For example, in a high-speed labeling machine, the 8LSC55.ee030ff00-4 maintains accurate registration even during frequent start-stop operations. Its thermal efficiency, with an insulation class F and a maximum winding temperature of 155°C, ensures consistent performance under continuous duty.

Installation and Setup

Mounting the 8LSC55.ee030ff00-4 is straightforward, following EN 60034-7 standards (IM 3001, IM 3011, IM 3031). The flange conforms to DIN 42948 Form A, and the shaft end meets DIN 748 Form E, ensuring compatibility with standard couplings. The motor is externally fan-cooled (IC4A0A6), so ensure adequate airflow around the fan for optimal cooling.

For electrical connections, the motor uses a connector size/type 1 and a cable cross-section of 1.5 mm². It is recommended to use the ACOPOS servo drive (model 024X) for best performance, as it supports the motor's feedback options (resolver or EnDat) and implements safety functions like STO.

Maintenance and Reliability

Routine maintenance is minimal, but periodic inspection of the fan and cooling paths is advised to prevent overheating. The motor's IP64 protection (per EN 60034-5) guards against dust and water splashes, while the fan is rated IP20 (or IP65 with an optional oil seal). Operating temperature range is -15°C to +40°C (up to +55°C with derating), and it can be installed at elevations up to 2000 m.

With a thermal time constant of 42 minutes, the motor handles thermal transients well, reducing the risk of damage from short-term overloads. Bearing life follows DIN ISO 281, and the vibration severity is A1 per EN 60034-14, ensuring smooth operation and long service life.

Compatibility and Integration

The 8LSC55.ee030ff00-4 is designed to work seamlessly with B&R ACOPOS servo drives, particularly the 024X model. It supports both resolver and EnDat feedback systems, including safety-related variants, enabling flexible integration into various control architectures. The single-cable option reduces wiring complexity, and the motor's compliance with LVD 2014/35/EU, EMC 2014/30/EU, and RoHS 2011/65/EU ensures it meets European regulatory standards.

For existing systems, this motor can replace older models with similar mounting dimensions, but always verify the mechanical interface and electrical compatibility with your current drive.

Comparison with Similar Motors

Compared to other servo motors in its class, the 8LSC55.ee030ff00-4 offers a higher torque-to-inertia ratio, which translates to faster response times. For instance, its stall torque of 27.3 Nm and maximum torque of 60.0 Nm provide a wide operating range, whereas some competitors may have lower peak capabilities. Additionally, the optional single-cable solution is a distinct advantage for reducing installation costs.

When evaluating alternatives, consider the total cost of ownership, including energy efficiency and maintenance. The 8LSC series is known for reliability, and this model's robust construction supports long-term operation in demanding environments.
