Berger Lahr VRDM3910/50LWBOO is an inverter-duty, two-phase stepper motor designed for converter-based control in automation systems. The unit operates from 230 VAC with a per‑phase current of 2.25 A and comes in a compact 90 x 90 x 190 mm housing that weighs about 3.26 kg. It uses a two‑arm (two‑winding) configuration for reliable inverter-drive performance, aligning with VPWM/VT control typically used in Berger Lahr VRDM motor applications.
