B&R 8LSA35.DB060S100-3 High-Speed Servo Motor 6000 RPM – 1.6 Nm, Multi-Turn EnDat 2.2 for Dynamic Automation

The B&R 8LSA35.DB060S100-3 is a high-performance synchronous servo motor specifically tailored for applications demanding high rotational speeds and precise positional control. Unlike standard 3000 RPM variants, this model operates at 6000 RPM, making it the optimal choice for high-dynamic processes such as rapid pick-and-place, high-speed labeling, and light-duty robotics.

At the heart of this motor is the EQI 1331 FS absolute multi-turn encoder, which communicates via the EnDat 2.2 protocol. With the ability to track absolute position across 4096 mechanical revolutions, this system eliminates the need for referencing runs after a power cycle—significantly reducing machine downtime and improving overall equipment effectiveness (OEE).

A Note on This Specific Configuration (Product Code Breakdown)

Breaking down the model code helps you understand what you are ordering:

• DB: Denotes the Multi-turn encoder feedback system.

• 060: Indicates the nominal speed of 6000 RPM (where "030" would mean 3000 RPM).

• S100: Refers to the winding design and stator length, optimized for high-speed torque delivery.

• -3: Confirms the single-cable connection system for streamlined cabling.

This unit is supplied without an integrated holding brake (identified by the missing brake option in the code). This brake-less configuration is intentional for applications where external mechanical braking is not required or where a separate safety circuit is already in place. It reduces motor weight and inertia, allowing for quicker acceleration and deceleration ramps.

The 14 mm keyed shaft provides a positive-locking torque transmission, ideal for connecting to timing pulleys, belt drives, and gearboxes where slip-free operation is mandatory. Combined with the angled swivel connector and IP64 protection, this motor is engineered for reliable operation in moderately harsh industrial environments.

Why Choose the 8LSA35.DB060S100-3?

• High-Speed Dynamics: 6000 RPM nominal speed enables faster cycle times compared to standard 3000 RPM motors, boosting production throughput.

• Absolute Positioning Confidence: Multi-turn EnDat 2.2 encoder ensures the machine always knows its exact position—even after emergency stops or power outages.

• Optimized for Horizontal Axes: Without a built-in brake, this motor has lower rotor inertia, making it highly responsive for horizontal moving axes and continuously rotating applications.

• Space-Saving Installation: Single-cable technology combines power and feedback into one hybrid cable, drastically reducing cable tray clutter and connection effort.

• Ready for Retrofitting: The 91.30 mm standard flange and 80 mm centering diameter ensure mechanical compatibility with existing B&R 8LSA35 setups and many third-party mounting interfaces.

• Energy Efficient: With a 94.0% efficiency rating, this motor contributes to lower operational energy costs and reduced heat dissipation in control cabinets.

Typical Applications

• High-Speed Packaging Lines: Indexing conveyors, film wrapping, and carton erectors requiring rapid start/stop cycles.

• Printing & Labeling Machinery: Precise web-fed printing and rotary label applicators that demand consistent speed and accurate registration marks.

• Pick-and-Place Systems: Light-load robotic arms and gantry systems for electronic assembly and small parts handling.

• Belt-Driven Transfer Units: Material handling modules where horizontal traverse speed is critical for production rhythm.

• Rotary Indexing Tables: Light to medium-duty turntables requiring quick positioning with multi-turn absolute feedback.

• Replacement & Upgrade Projects: Direct drop-in replacement for failed or outdated servo motors in existing 8LSA35-based machine designs.

Frequently Asked Questions (FAQ)

Q1: What is the main difference between the DB060 and DB030 variants in the 8LSA35 series?
The key difference is the nominal speed. The DB060 (this model) is rated for 6000 RPM with 1.60 Nm torque, designed for high-speed operation. The DB030 is rated for 3000 RPM with a higher nominal torque of 2.10 Nm, prioritizing torque over speed. Choose DB060 for dynamic, fast-moving horizontal axes, and DB030 for heavier loads or vertical applications with brake.

Q2: Can I use this motor for a vertical lifting axis?
Not recommended. This specific model does not include a holding brake. Without a mechanical brake, the load could drop when power is removed. For vertical lifting, we recommend selecting an 8LSA35 variant with an integrated brake (e.g., the DB030S300-3) or adding an external safety brake to your mechanical design.

Q3: What is the advantage of the single-cable solution?
The single-cable hybrid technology combines both motor power and encoder feedback signals into one physical cable and connector. This reduces the number of cables by half, simplifies installation, lowers spare parts inventory, and minimizes potential failure points from loose connections.

Q4: Does this motor come with the mating connector?
Typically, the motor includes the angled swivel connector on the motor side. However, the mating connector for the drive-side cable harness is usually ordered separately. Please check your B&R drive interface requirements or consult your system integrator.

Q5: Is the EQI 1331 encoder compatible with third-party drives?
The encoder uses the standard EnDat 2.2 digital protocol. While it is physically compatible with any EnDat 2.2 interface, the motor performance and parameterization are optimized for B&R servo drives (ACOPOS/ACOPOSmulti) . For best results, use it within a B&R ecosystem, or ensure your third-party drive has appropriate motor parameter libraries for 8LSA series.
