Why the 8LSC44.ee030ffgg-4 Matters for Your Bottom Line
In modern manufacturing, every minute of unplanned downtime hits your profitability. The B&R 8LSC44.ee030ffgg-4 three-phase synchronous servo motor is engineered to keep your lines running. Its permanent-magnet design delivers excellent dynamic characteristics and positioning precision, which directly reduces cycle times and scrap rates.
This motor also features a large overload capacity, so it handles peak loads without tripping. That resilience minimizes production interruptions and lowers maintenance costs. For plant managers, this translates into a lower total cost of ownership over the motor's service life.
Technical Specifications: Performance That Pays Off
The 8LSC44.ee030ffgg-4 offers a nominal speed of 3000 rpm and a nominal torque of 7.0 Nm. With a stall torque of 8.5 Nm and a maximum torque of 22.8 Nm, it provides the muscle for demanding applications. The torque constant of 1.63 Nm/A means efficient energy conversion, reducing electricity consumption per unit of work.
Its moment of inertia is 2.6 kg·cm², which allows rapid acceleration and deceleration. This agility shortens cycle times, boosting throughput. The motor's mass is 6.82 kg (without brake), making it compact and easy to integrate into space-constrained machinery.
For safety-critical processes, the optional brake offers a holding torque of 8 Nm. This ensures the load stays put when power is removed, preventing accidents and protecting your equipment. The brake adds 1.000 kg and 0.69 kg·cm² to the system, a small price for enhanced safety.
Cost Analysis: Where the 8LSC44.ee030ffgg-4 Saves You Money
Energy efficiency is a major cost driver. The motor's nominal current of 4.3 A and stall current of 5.2 A indicate a design that uses power judiciously. Lower current draw means smaller power supplies and reduced energy bills over time.
Reliability also cuts costs. The motor is rated for continuous operation (S1) per EN 60034-1, so it can run 24/7 without derating. This reduces the need for redundant units and lowers spare-part inventory. The thermal protection (KTY83-110 / AM-PTC1000) prevents overheating, extending motor life and avoiding costly burnouts.
Maintenance is another area of savings. The externally fan-cooled design (IC4A0A6) uses a machine-mounted fan that is easy to service. With IP64 protection (IP65 with optional oil seal), the motor resists dust and water ingress, reducing failure rates in harsh environments.
Application Scenarios: Where This Motor Shines
In packaging lines, the 8LSC44.ee030ffgg-4 provides the precise positioning needed for accurate filling and sealing. Its high maximum speed of 6600 rpm allows fast indexing, boosting line output. The low inertia ensures quick starts and stops, minimizing product waste.
In material handling, the motor's high overload capacity (22.8 Nm) handles sudden load spikes without stalling. This reliability keeps conveyors moving and reduces jams. The single-cable (hybrid) solution option simplifies wiring, cutting installation time and costs.
For machine tools, the motor's torque constant of 1.63 Nm/A ensures smooth, controlled cutting. The optimized torque rippling improves surface finish, reducing rework. With a resolver or EnDat feedback, the motor delivers the accuracy required for precision machining.
Compatibility and Integration
The 8LSC44.ee030ffgg-4 is designed to work seamlessly with B&R ACOPOS servo drives (recommended drive: 8X8X). This pairing ensures optimal performance and easy commissioning. The motor supports resolver (R0/R2) or EnDat feedback, including safety-related variants, giving you flexibility in control architecture.
For safety, the motor can be equipped with encoders for functional safety, and the ACOPOS drive implements STO (Safe Torque Off). This integration simplifies safety system design, reducing engineering effort and certification costs.
Frequently Asked Questions
What is the nominal torque of the 8LSC44.ee030ffgg-4?
The nominal torque is 7.0 Nm, with a stall torque of 8.5 Nm. This provides a solid margin for continuous operation, ensuring the motor can handle typical loads without overheating.
Can this motor be used in high-speed applications?
