Solving High-Speed Precision Challenges
In modern manufacturing, engineers face a common dilemma: achieving high throughput while maintaining exact positioning accuracy. The B&R 8LSC44.ee060ff00-4 three-phase synchronous servo motor directly addresses this challenge. It delivers a nominal speed of 6000 rpm and a nominal torque of 5.3 Nm, making it suitable for applications that demand both speed and precision.
This motor is part of the 8LSC series, known for its compact size and reduced weight. Its permanent-magnet, electronically commutated design ensures excellent dynamic characteristics. For engineers, this means faster cycle times without sacrificing control quality.
Technical Specifications: What the Numbers Mean
Understanding the key parameters helps you select the right motor for your application. The 8LSC44.ee060ff00-4 offers a nominal power of 3349 W and a nominal current of 6.6 A. Its stall torque is 8.5 Nm, providing strong holding force when needed.
The motor's maximum torque reaches 22.8 Nm, with a maximum current of 43.8 A. This overload capacity is crucial for handling short-duration peak loads. The torque constant is 0.81 Nm/A, and the voltage constant is 49.22 V/1000rpm, ensuring predictable performance.
Key electrical parameters include a stator resistance of 0.96 Ohm and a stator inductance of 7.5 mH. The electrical time constant is 7.8 ms, while the thermal time constant is 25 minutes. The moment of inertia is 2.6 kg·cm², and the motor mass (without brake) is 6.82 kg.
For applications requiring a brake, the holding torque is 8 Nm, with a brake mass of 1.000 kg and a brake inertia of 0.69 kg·cm². The cable cross-section is 0.75 mm², and the recommended servo drive is the ACOPOS 013X.
Application Scenarios: Where This Motor Excels
The 8LSC44.ee060ff00-4 is ideal for high-speed pick-and-place machines. In such systems, the motor's 6000 rpm nominal speed and 5.3 Nm torque enable rapid, precise movements. Its compact design allows for space-saving machine layouts.
Another key application is in packaging equipment, where precise registration and consistent torque are essential. The motor's large overload capacity (22.8 Nm maximum torque) handles sudden load changes without losing synchronization. The single-cable hybrid solution option simplifies wiring and reduces installation time.
In a typical electronics assembly line, this motor can drive a rotary index table. The encoder options, including functional safety variants, provide the feedback needed for accurate positioning. The optimized torque rippling ensures smooth motion, which is critical for delicate component handling.
Compatibility and Integration
The 8LSC44.ee060ff00-4 is designed to work seamlessly with B&R ACOPOS servo drives, specifically the 013X model. This pairing ensures optimal performance and easy commissioning. The motor supports resolver or EnDat feedback systems, including safety-related variants.
For system integration, the motor offers a single-cable (hybrid) solution that combines power and feedback in one cable. This reduces cabling complexity and potential failure points. The built-in plug-in connectors further simplify installation.
Regarding environmental compliance, the motor conforms to LVD 2014/35/EU, EMC 2014/30/EU, and RoHS 2011/65/EU. It meets standards EN 60034-1/7/11/14. Note that it is NOT C-UR-US listed; only the 8LSA series carries UL certification (file E360421).
Real-World Application Example
Consider a high-speed bottling line where capping heads must align perfectly with each bottle. The 8LSC44.ee060ff00-4, with its 6000 rpm speed and 5.3 Nm torque, can drive the capping turret with precision. The motor's compact size allows for a more streamlined machine design, reducing floor space.
In this scenario, the motor's overload capacity (22.8 Nm) handles the momentary resistance when the cap is tightened. The encoder feedback ensures that each cap is applied at the exact correct torque. This results in fewer rejects and higher throughput.
