Key Takeaways

• Siemens adds the Sinamics E210 ELV converter and Simotics E‑1EE1 servomotors to its low‑voltage drive line.
• Both devices operate on 24 V or 48 V battery packs, eliminating the need for intermediate DC‑DC stages.
• Integrated PROFIsafe, PROFINET IRT, and TIA Portal/Simove support cut engineering time by up to 30 %.
• The motor‑converter pair delivers SIL 2 safety, regenerative braking, and optional gear/ brake options for AGVs, AMRs and driver‑less transport.

Siemens Broadens ELV Drive Portfolio for Mobile Intralogistics

Siemens has announced a new, tightly coupled drive solution aimed at battery‑powered mobile equipment. The offering pairs the Sinamics E210 compact converter with the Simotics E‑1EE1 family of extra‑low‑voltage (ELV) servomotors. Together they target automated guided vehicles (AGVs), autonomous mobile robots (AMRs) and other driver‑less transport platforms that rely on 24 V or 48 V battery systems.

Sinamics E210 – Compact Regenerative Converter

The Sinamics E210 is engineered for 24 V and 48 V battery architectures. As a regenerative drive, it can feed kinetic energy back into the battery during braking, improving overall system efficiency by 5‑8 % in typical AGV duty cycles. Key features include:

Direct connection to the battery eliminates auxiliary converters, reducing wiring complexity and weight—critical factors for mobile platforms where every kilogram matters.

Simotics E‑1EE1 – ELV Servomotors for Higher Power

The Simotics E‑1EE1 series expands Siemens’ ELV motor range into the higher torque regime required for wheel drives, steering actuators and lifting mechanisms. Motors are offered in shaft heights 40 mm, 50 mm, 63 mm, delivering up to 2.5 kW and 250 Nm of continuous torque.

A built‑in 14‑bit BiSS‑C safety encoder provides precise position feedback while meeting SIL 2 requirements without external safety modules. The electronic nameplate enables the Sinamics E210 to pull motor parameters automatically during commissioning, cutting set‑up time by an estimated 20 %.

Integrated Drive System for Mobile Intralogistics

By pairing the E210 converter with an E‑1EE1 motor, system integrators obtain a single‑platform solution that bundles drive control, safety functions and network communication. Benefits include:

• Reduced engineering effort – the combined hardware can be configured entirely within the TIA Portal, eliminating separate safety PLCs.
• Scalable architecture – additional axes (e.g., lift, tilt) can be added using the same ELV family, preserving a uniform voltage level across the vehicle.
• Future‑proofing – native PROFINET IRT and PROFIsafe support simplify upgrades for cybersecurity and functional safety updates.

The solution is especially attractive for AGVs that require precise traction control, AMRs that need fast steering response, and driver‑less transport carts used in warehouses or factories.

Bottom Line

Siemens’ new ELV drive pair—Sinamics E210 and Simotics E‑1EE1—delivers a compact, battery‑direct solution for the growing market of electric mobile intralogistics. By operating exclusively at 24 V/48 V, the system removes the inefficiencies of intermediate converters, while built‑in safety and seamless TIA Portal integration shrink development cycles. For manufacturers of AGVs, AMRs and driver‑less transport equipment, the combined offering provides a future‑ready, scalable platform that meets both performance and safety demands without the overhead of legacy voltage conversion hardware.
