Why the 8LSC47.ee030ffgg-4 Matters for Modern Automation
In today's competitive manufacturing environment, every axis of motion must deliver both precision and efficiency. The B&R 8LSC47.ee030ffgg-4 three-phase synchronous servo motor addresses this need with a design that balances dynamic performance with operational economy. As part of the 8LSC series, this motor is engineered for applications requiring excellent dynamic characteristics, positioning precision, compact size, and reduced weight.
For engineers evaluating motion control upgrades, the 8LSC47.ee030ffgg-4 offers a compelling mix of power density and control accuracy. Its permanent-magnet, electronically commutated design ensures high efficiency, while the large overload capacity provides a safety margin for demanding cycles. This article breaks down the motor's key specifications, explores real-world applications, and analyzes how its technical features translate into cost savings and ROI.
Key Technical Specifications and Performance
The 8LSC47.ee030ffgg-4 is a performance-oriented servo motor with a nominal speed of 3000 rpm and a maximum speed of 6600 rpm. It delivers a nominal torque of 13.3 Nm and a stall torque of 15.6 Nm, with a maximum torque of 45.6 Nm for short-duration peak loads. The nominal power is 4170 W, and the nominal current is 8.1 A, with a maximum current of 44.0 A.
These figures indicate a motor that can handle both high-speed continuous operation and sudden torque demands. The torque constant of 1.63 Nm/A and voltage constant of 98.44 V/1000rpm show a well-matched electromagnetic design. With a stator resistance of 1.66 Ohm and inductance of 14.1 mH, the motor offers predictable electrical behavior. The electrical time constant of 8.5 ms and thermal time constant of 27 minutes provide insight into its dynamic response and thermal stability.
Mechanically, the motor has a moment of inertia of 4.8 kg·cm² and a mass of 9.55 kg without brake. The optional brake provides a holding torque of 15 Nm and adds 1.00 kg to the mass. The motor is rated for continuous operation (S1) per EN 60034-1, with insulation class F (IEC 60085). Cooling is provided by an externally mounted fan (IC4A0A6), ensuring consistent performance even under sustained load.
Cost-Efficiency Through Design and Performance
The 8LSC47.ee030ffgg-4's specifications directly impact total cost of ownership. Its high overload capacity (maximum torque of 45.6 Nm vs. nominal 13.3 Nm) allows the motor to handle peak loads without oversizing, reducing initial capital expenditure. The wide speed range (up to 6600 rpm) provides flexibility across different applications, potentially eliminating the need for multiple motor sizes.
Energy efficiency is another cost factor. The permanent-magnet synchronous design inherently offers high efficiency, which lowers electricity consumption over the motor's lifetime. The externally fan-cooled design (IC4A0A6) ensures that the motor maintains its rated performance without derating, even in continuous-duty cycles. This reliability translates into fewer production interruptions and lower maintenance costs.
Furthermore, the motor's compact size and reduced weight (9.55 kg) simplify installation and reduce structural requirements. The single-cable (hybrid) solution option minimizes cabling costs and installation time. These factors combine to reduce both upfront and operational expenses, making the 8LSC47.ee030ffgg-4 a cost-effective choice for high-performance automation.
Real-World Applications and Use Cases
The 8LSC47.ee030ffgg-4 is suited for a variety of industrial applications that demand precise motion control. In packaging machinery, for example, the motor's high dynamic response and positioning accuracy enable rapid, accurate indexing and filling operations. The large overload capacity handles intermittent loads, such as cutting or sealing mechanisms, without compromising cycle times.
In material handling and robotics, the motor's compact design and high torque density allow for smaller, lighter end-effectors. The optional encoders for functional safety support safe motion monitoring, which is critical for collaborative applications. The motor's IP64 protection rating (with optional IP65 with oil seal) makes it suitable for environments with dust and light moisture.
Another typical scenario is in machine tool spindles or feed axes. The 8LSC47.ee030ffgg-4's speed range and torque characteristics provide the necessary performance for milling, drilling, or turning operations. The motor's low torque ripple, optimized for good controllability, ensures smooth surface finishes and reduces tool wear.
Compatibility and Integration
The 8LSC47.ee030ffgg-4 is designed to work seamlessly with B&R's ACOPOS servo drives. The recommended drive series is ACOPOS 013X, which provides the necessary power and control algorithms. The motor supports both resolver and EnDat feedback systems, including safety-related variants, allowing integration into safety-rated applications.
The motor features built-in plug-in connectors and a single-cable (hybrid) solution option, which simplifies wiring and reduces installation errors. The connector size/type is specified as "1", and the cable cross-section is 0.75 mm². This standardized interface ensures compatibility with B&R's ecosystem and reduces commissioning time.
For system integrators, this compatibility means lower engineering effort and faster time-to-market. The motor's compliance with LVD 2014/35/EU, EMC 2014/30/EU, and RoHS 2011/65/EU ensures it meets European regulatory requirements, simplifying machine certification.
Frequently Asked Questions
What is the maximum speed of the 8LSC47.ee030ffgg-4?
The maximum speed is 6600 rpm, while the nominal speed is 3000 rpm. This wide range allows the motor to operate efficiently across various speed requirements, from high-speed continuous processes to lower-speed high-torque applications.
What is the overload capacity of this motor?
The motor has a maximum torque of 45.6 Nm, which is more than three times the nominal torque of 13.3 Nm. This large overload capacity enables the motor to handle peak loads without oversizing, saving cost and space.
Does the 8LSC47.ee030ffgg-4 support functional safety?
Yes, the motor can be equipped with encoders for functional safety. Additionally, the Safe Torque Off (STO) function is implemented via the ACOPOS servo drive, not within the motor itself. This allows for safe integration into safety-rated machinery.
What cooling method does this motor use?
The motor is externally fan-cooled (IC4A0A6), with a machine-mounted independent fan component. This ensures consistent cooling even at low speeds, maintaining performance and extending component life.
