Delta Line Expands Its Range Leo Brushless DC Drives Family with the Introduction of New Leo B3800 and Leo B860.

Why It Matters

The new drives give machine builders a single source for high‑performance and space‑constrained applications, accelerating system integration and reducing component sprawl. Their safety and connectivity features align with Industry 4.0 demands, strengthening Delta Line’s competitive edge.

Key Takeaways

• B3800 delivers up to 3800 W, 80 A rms
• B860 offers 860 W power in compact footprint
• Both support multiple fieldbus protocols for integration
• Integrated SIL3/Ple Safe Torque Off enhances safety
• Expanded portfolio covers intralogistics to robotics applications

Pulse Analysis

The brushless DC (BLDC) drive market is increasingly driven by the need for higher power density and seamless digital integration. Manufacturers seek solutions that can handle demanding torque requirements while fitting into tighter mechanical envelopes. Delta Line’s introduction of the Leo B3800 and B860 addresses these trends by delivering a broad power spectrum—from 860 W to 3800 W—under a unified architecture that simplifies procurement and maintenance for system integrators.

The Leo B3800 targets high‑performance applications, offering up to 80 A rms continuous current and a peak of 240 A, sufficient to drive Delta Line’s top‑tier servo motors such as the 100SV, 110SV, and 130SV series. Its 12‑60 VDC supply range and built‑in protections make it suitable for heavy‑duty robotics and machine tools. Conversely, the Leo B860 focuses on compactness and cost efficiency, delivering 18 A rms with a modest footprint ideal for space‑constrained equipment like pick‑and‑place cells. Both models incorporate SIL3/Ple Safe Torque Off, supporting incremental and absolute encoders, and they communicate over CANopen, EtherCAT, Modbus, Profinet, Powerlink, and Ethernet/IP, ensuring plug‑and‑play compatibility across diverse automation ecosystems.

By filling the gap between low‑end Gemini drives and higher‑end B1400 units, Delta Line creates a seamless product ladder that reduces the need for multiple vendor relationships. This strategic expansion positions the company to capture growth in sectors such as intralogistics, where compact yet powerful drives are essential, and advanced robotics, which demand precise, safe, and network‑ready motion control. As Industry 4.0 standards evolve, the integrated safety functions and multi‑protocol support of the new Leo drives will likely become baseline expectations, reinforcing Delta Line’s relevance in the competitive motion‑control landscape.
