Berger Lahr WD3-007.0501 Stepper Motor Drive

The Berger Lahr WD3-007.0501 Stepper Motor Drive (WD30070501) is an industrial-grade three-phase stepper drive designed to interface digital-positioning systems with 3-phase stepping motors, drawing its power from a 230 VAC mains supply. The controller accepts a 24 V control signal input and provides a regulated drive output at up to 2.5 A per phase, with a practical operating frequency range of 45–66 Hz to balance torque and speed. As part of the WD3 family, the WD3-007 series is documented for use in automation and motion-control applications where reliable torque delivery and simple 24 V signaling are required, including legacy machines that rely on Berger Lahr control hardware. This particular revision is noted as Rev. 04 (WD30070501), with alternate part references WD3-007 and WD3-007.0501; buyers should verify compatibility with their motor and control system, and anticipate sourcing challenges given the model’s age. Common catalog listings emphasize its 230 VAC input, 45–66 Hz drive frequency, 2.5 A per phase current, and 24 V signal input, making it a direct option for legacy Berger Lahr drive configurations in industrial automation.
