B&R 8LSA55.R2030D300-3 High-Torque Servo Motor: Precision Powerhouse for Industrial Automation

Engineered Excellence for Demanding Production Environments

As a proud member of the ABB Group, B&R introduces the 8LSA55.R2030D300-3 synchronous servo motor, setting new standards in high-torque motion control. Designed specifically for heavy-duty applications in packaging, printing, food processing, and textile manufacturing, this motor combines 12,500 Nm stall torque with 3,000 RPM operation in a robust, industrial-grade package.

What truly distinguishes this model is its perfect balance of holding brake security (15.00 Nm) and keyed shaft reliability, making it the ideal solution for vertical applications and high-inertia loads where safety and precision are non-negotiable.

• Gravure cylinders: Handles heavy rotary loads smoothly

• Digital printing: Provides precise registration control

Food Processing

• High-capacity mixers: Handles viscous materials effortlessly

• Packaging lines: IP64 rating withstands washdown cleaning

• Conveying systems: Keyed shaft prevents slippage in wet conditions

Textile Manufacturing

• Fabric rolling machines: Controls heavy material rolls

• Yarn twisting equipment: Maintains consistent torque

• Non-woven production: Handles wide material webs

Why the R2030D300-3 Stands Out

1. Dual Security Advantage: Combines keyed shaft and holding brake for ultimate safety

2. Maintenance Minimized: Self-cooling design reduces service requirements

3. Precision Guaranteed: 130mm centering ensures perfect alignment

4. Versatile Application: Ideal for both horizontal and vertical installations

Selection Guidance

• Choose D000-3 for basic horizontal applications without brake requirements

• Select D100-3 when keyed shaft is needed but braking isn't necessary

• Opt for D200-3 for vertical applications with smooth shaft requirements

• Specify D300-3 (current model) for vertical/high-inertia applications needing both brake and keyed shaft

Conclusion: The Smart Choice for Heavy Industrial Automation

The B&R 8LSA55.R2030D300-3 represents the pinnacle of the R2030D series, offering:

• Unmatched safety with dual brake and keyed shaft features

• Superior torque density for direct drive applications

• Industrial durability for harsh production environments

• Maintenance-friendly design for reduced downtime

For engineers specifying motors for demanding packaging, printing, food, or textile applications, this model delivers the perfect combination of power, precision, and reliability - all backed by ABB Group's world-class engineering expertise. Its unique positioning in the series makes it the ideal choice when both braking security and positive shaft connection are required.
