B&R 8LSA46.R2030D300-3 Servo Motor: Precision Power for Packaging & Textile Automation
Revolutionizing High-Speed Production with Unmatched Performance
In the fast-paced world of packaging, printing, food processing, and textile manufacturing, the B&R 8LSA46.R2030D300-3 synchronous servo motor stands as a game-changing solution. Engineered specifically for industries demanding ultra-precise motion control at blistering speeds, this motor combines 10,000 Nm of stall torque with 3,000 RPM operation in a remarkably compact, self-cooling package.
What truly sets this motor apart is its integrated holding brake system - a critical feature for vertical applications in packaging lines where safety and position retention are paramount. The 95mm centering diameter with j6 fit ensures vibration-free operation even in high-cycle applications like rotary printing presses, while the IP64 protection guarantees reliability in environments where flour dust, textile fibers, or liquid splashes are constant challenges.
